[Product purchase process]
Next, the outline of the product purchase process by the purchase management system 100 will be described. The product purchase process is a process in which a customer purchases a product at a store 8 using a mobile terminal 3. FIG. 6 is a flowchart showing an outline of the product purchase process. The product purchase process is roughly classified into a store entry process S100, a product selection process S200, and an accounting process S300. The product purchase process is mainly realized by the management server 2, the mobile terminal 3, and the accounting machine 5 executing programs prepared in advance.

(Store entry process)
First, the store entry process will be described. The store entry process is a process performed prior to the purchase of a product when a customer enters the store 8, and corresponds to preparation for the purchase of the product. FIG. 7 is a flowchart showing an example of the store entry process. This process is performed by the mobile terminal 3 and the management server 2.

First, when the customer enters the store 8, the customer reads the store barcode using the mobile terminal 3 (step S101). The store barcode is affixed to a predetermined place in the store 8, for example, a wall near the entrance of the store, a card used for shopping, or the like. When the customer reads the store barcode, the mobile terminal 3 acquires the store ID from the read store barcode and transmits it to the management server 2 (step S102). When transmitting the store ID, the mobile terminal 3 also transmits the customer identification information that identifies the customer who uses the mobile terminal 3 or the mobile terminal 3. In the product selection process and the accounting process described below, the mobile terminal 3 basically transmits the customer identification information for identifying itself when transmitting some information to the management server 2.

The management server 2 receives the store ID from the mobile terminal 3 and acquires the selling price list of the store from the product information DB 28 (step S104). This is because the selling price of the product is different for each store. Then, the management server 2 transmits the store information including the store name and the sale information of the store to the mobile terminal 3 (step S105), and the mobile terminal 3 receives the store information (step S106). As a result, the current store name, sale information of the store, and the like are displayed on the display unit 31 of the mobile terminal 3, and the customer can start shopping. The store information transmitted by the management server 2 includes information indicating the transaction status of the customer at the store, and when a new shopping is started at the store, the transaction status becomes new. On the other hand, when the customer interrupts shopping at the store for some reason, the purchased product list screen corresponding to the transaction state up to that point is displayed on the mobile terminal 3.

(Product selection process)
Next, the product selection process will be described. The product selection process is a process in which the customer uses the mobile terminal 3 to read the product barcode 7 attached to the product and registers it in the purchased product list. FIG. 8 is a flowchart of the product selection process. This process is executed by the mobile terminal 3 and the management server 2.

First, when the customer finds a product he / she wants to purchase, he / she puts the mobile terminal 3 into the product reading mode and reads the product barcode 7 attached to the product by the mobile terminal 3 (step S201: Yes). The mobile terminal 3 transmits the read product identification information of the product to the management server 2 (step S203). At this time, the quantity of the product is automatically set to "1". When the management server 2 receives the product identification information from the mobile terminal 3 (step S203), the management server 2 updates the purchased product list and transmits it to the mobile terminal 3 (step S204). The mobile terminal 3 receives the updated product list and displays it on the display unit 31 (step S205). As a result, the newly added product and its quantity are added to the purchased product list and displayed on the mobile terminal 3 as the purchased product list screen.

Next, when the customer operates the mobile terminal 3 to change the quantity of the product as needed, the mobile terminal 3 acquires the changed quantity (step S206: Yes). When the product barcode is first read, the quantity of the product is automatically set to "1", but when the customer purchases the same product more than once, the mobile terminal 3 is operated to set the quantity. Can be changed. When the changed quantity is set, the mobile terminal 3 transmits the product identification information of the product to be changed and the changed quantity to the management server 2 (step S207).

When the management server 2 receives the product identification information and the changed quantity from the mobile terminal 3 (step S208), the management server 2 updates the purchased product list and transmits it to the mobile terminal 3 (step S209). The mobile terminal 3 receives the updated purchased product list and displays it on the display unit 31 as a purchased product list screen (step S210). As a result, the quantity change is reflected in the purchased product list.

Next, the mobile terminal 3 determines whether or not the payment button 45 has been pressed by the customer (step S211). The payment button 45 is a button that the customer presses when completing the shopping. If the payment button 45 is not pressed (step S211: No), the process returns to step 201. In this way, the customer can add products, change the quantity, and continue shopping until the payment button 45 is pressed. Then, when the payment button 45 is pressed (step S211: Yes), the product selection process ends.

FIG. 9 shows a display example of the purchased product list screen displayed on the mobile terminal 3. In this example, the purchased product list screen has a product reading button 40, a list display field 41, a subtotal display field 42, a total amount display field 43, a home screen transition button 44, a payment button 45, and a transaction cancellation button. It has 46 and. The purchased product list screen is an example of the purchased product screen.

When the mobile terminal 3 detects that the product reading button 40 has been selected by a tap operation or the like, the mobile terminal 3 switches the display of the display unit 31 to the product reading screen. On the product reading screen, the mobile terminal 3 displays an image or the like acquired from the activated reading unit 36. As a result, the customer can move the product or the mobile terminal 3 so that the product barcode 7 is located within the reading range of the reading unit 36, and can read the product barcode 7.

In the list display column 41, the name, quantity, and price of the purchased product are displayed for each purchased product. Further, a quantity decrease button 47 and a quantity increase button 48 are displayed for each purchased product in the list display field 41. Then, when the mobile terminal 3 accepts the quantity change of the purchased product by the quantity decrease button 47 or the quantity increase button 48, the mobile terminal 3 transmits the product identification information of the purchased product whose quantity has been changed and the changed quantity to the management server 2. ..

The subtotal display column 42 displays the subtotal of the selling price excluding tax for all the products in the purchased product list, and the total amount display column 43 displays the total amount of the selling price including tax for all the products in the purchased product list. The management server 2 calculates these subtotals or total amounts based on the prices of the purchased products registered in the product information DB 28, specifically, the selling price list of the store acquired by the store entry process.

When the mobile terminal 3 detects that the home screen transition button 44 is selected, it transmits a home screen display request to the management server 2 and displays a predetermined home screen based on the display information received as a response. The home screen may display information on discounts and discounts at the store 8, customer registration information on the mobile terminal 3, and the like.

When the mobile terminal 3 detects that the payment button 45 has been selected, it transmits an accounting request to the management server 2 and displays a payment method selection screen based on the display information received as a response. Further, when the mobile terminal 3 detects that the transaction cancellation button 46 is selected, the mobile terminal 3 transmits information for notifying the transaction cancellation to the management server 2. In this case, the management server 2 deletes the purchased product list corresponding to the mobile terminal 3.

(Accounting)
Next, the accounting process will be described. The accounting process is a process of paying for a product selected by a customer by a product selection process. FIG. 10 is a flowchart of accounting processing. This process is executed by the mobile terminal 3, the management server 2, and the accounting machine 5.

First, when the payment button 45 described above is pressed, the mobile terminal 3 transmits an accounting request to the management server 2 (step S301). When the management server 2 receives the accounting request (step S302), the management server 2 calculates the payment amount based on the purchased product list at that time (step S303). The management server 2 transmits a payment method selection screen including the purchased product list and the payment amount calculated in step S303 to the mobile terminal 3 (step S304).

The mobile terminal 3 displays the received payment method selection screen on the display unit 31 (step S305). FIG. 11 is a display example of the payment method selection screen. In this example, the payment method selection screen includes a list display field 61, a subtotal display field 62, a total amount display field 63, a credit button 64, an electronic money button 65, and a cash button 66. In the list display field 61, the name, quantity, and price of the purchased product are displayed. The subtotal display column 62 displays the subtotal of the selling price excluding tax for all the purchased products displayed in the list display column 61, and the total amount display column 63 displays the total amount of the selling price including tax for all the purchased products. The customer confirms the payment amount by looking at the payment method selection screen, and presses any of the credit button 64, the electronic money button 65, and the cash button 66. The payment method selection screen includes a list display field 61 and a subtotal display field 62, but the present invention is not limited to this, and it is sufficient if the payment amount can be confirmed and the payment method can be selected.

When the credit button 64 or the electronic money button 65 is pressed, that is, when the payment method is not cash (step S306; No), the control unit 35 of the mobile terminal 3 makes a payment according to the selected payment method. (Step S307).

Specifically, when the customer selects payment by credit by pressing the credit button 64, the mobile terminal 3 displays the name of the credit company that makes the credit payment, the credit card number, the payment amount, and the like. Then, when the customer receives a payment request by pressing the payment button or the like, the mobile terminal 3 prompts the input of a personal identification number or the like as necessary to perform credit payment. In addition, the customer can use his / her mobile terminal 3 by registering a credit card with the store operating company when registering as a member, or by registering with a payment agency contracted by the store. You can use it to make credit payments.

When the payment is completed, the mobile terminal 3 displays the accounting end screen (step S308). FIG. 12A shows a display example of the accounting end screen displayed on the display unit 31 when the credit settlement is completed. FIG. 12A is an example when the customer selects credit card payment, and the accounting end screen includes a payment information field 71, a receipt button 72, and an end button 73. The payment information column 71 displays information such as the payment amount and the payment method, for example, the card company name. The receipt button 72 is a button for printing out a receipt. The end button 73 is a button for confirming that the customer has completed the accounting process. When the customer presses the end button 73, the mobile terminal 3 reports to the management server 2 that the payment has been completed, and returns the display of the display unit 31 to the main menu.

When the customer selects payment with electronic money by pressing the electronic money button 65, the mobile terminal 3 displays various electronic money that can be used for payment, the payment amount, and the like. Then, upon receiving the payment request by pressing the payment button of the customer, the mobile terminal 3 prompts the user to select the electronic money to be used for payment from a plurality of electronic money as necessary, and performs the electronic money payment. When the payment is completed, the mobile terminal 3 displays the accounting end screen (step S308). FIG. 12B is an example when the customer selects electronic money payment, and the accounting end screen includes a payment information field 74, a receipt button 75, and an end button 76. The payment information column 74 displays information such as the payment amount, the payment method, for example, the name of the electronic money, and the balance of the electronic money. Since the receipt button 75 and the end button 76 are the same as the receipt button 72 and the end button 73 in FIG. 12 (A), the description thereof will be omitted.

On the other hand, when the cash button 66 is pressed, that is, when the payment method is cash (step S306; Yes), the control unit 35 of the mobile terminal 3 transmits the cash payment request to the management server 2. When the management server 2 receives the cash payment request (step S309), the management server 2 generates an accounting barcode based on the purchased product list at that time (step S310). The accounting barcode is information that uniquely identifies the purchase content indicated by the currently purchased product list. In one example, the accounting barcode can be a random code uniquely associated with the purchase content at that time. In this case, the accounting barcode has a meaning as an inquiry number for payment information. The management server 2 transmits a payment screen including the payment amount calculated in step S303 and the accounting barcode generated in step S310 to the mobile terminal 3 (step S311).

The mobile terminal 3 displays the received payment screen on the display unit 31 (step S312). FIG. 13 is a display example of the payment screen. In this example, the payment screen includes an accounting barcode 67, a total amount field 68, and a completion button 69. The customer moves to the accounting machine 5 with the mobile terminal 3 on which the payment screen is displayed, and reads the accounting barcode with the barcode reader 56 (step S313). The accounting machine 5 displays a cash payment screen based on the read accounting barcode (step S314). Specifically, the accounting machine 5 transmits the inquiry number indicated by the accounting barcode to the management server 2 and acquires payment information from the management server 2. The payment information includes details such as the total amount and the IDs and quantities of all the products in the purchased product list. The accounting machine 5 displays a cash payment screen based on the acquired payment information.

FIG. 14A shows a display example of the cash payment screen. On the cash payment screen, a total amount column 77 and a message prompting cash to be inserted into the cash slot are displayed. When the customer inserts cash into the cash slot, the accounting machine 5 pays change as needed. When the cash settlement is completed (step S315), the accounting machine 5 displays the accounting end screen (step S316). FIG. 14B shows a display example of the accounting end screen. FIG. 14B is an example when the customer selects cash settlement, and the accounting end screen includes a settlement information field 78, a receipt button 79, and an end button 80. The payment information column 78 displays information such as the amount of payment. Since the receipt button 79 and the end button 80 are the same as the receipt button 72 and the end button 73 in FIG. 12 (A), the description thereof will be omitted. When the customer presses the end button 80, the accounting machine 5 reports to the management server 2 that the settlement has been completed, and returns the display of the display unit 51 to the main menu. As shown in FIG. 13, the completion button 69 is also displayed on the payment screen displayed on the mobile terminal 3, and the customer presses the completion button 69 on the payment screen when the accounting process is completed. When the completion button 69 is pressed, the mobile terminal 3 reports to the management server 2 that the payment has been completed, and returns the display unit 31 to the main menu.

In the above example, the accounting barcode is simply an inquiry number for payment information, and the accounting machine 5 uses this inquiry number to acquire payment information from the management server 2. Instead, the accounting barcode may include payment information. That is, when the management server 2 receives the cash payment request, it generates an accounting barcode using the total amount and the information of the purchased product list based on the contents of the purchased product list at that time. In this case, the accounting machine 5 can acquire the payment information by reading and decoding the accounting barcode, so that it is not necessary to communicate with the management server 2 in order to acquire the payment information. That is, the accounting machine 5 may extract the total amount from the read accounting barcode and display the payment method selection screen.

[Eat-in selection process]
Since October 2019, the reduced tax rate system has been introduced as the consumption tax rate has been raised to 10%. The reduced tax rate is a consumption tax rate (for example, 8%) set lower than the standard tax rate (for example, 10%) for a specific product. Products subject to the reduced tax rate (hereinafter referred to as "products subject to the reduced tax rate") are, for example, food and drink products. However, if you eat in the purchased product, the reduced tax rate will not be applied to the product and the standard tax rate will be applied. Therefore, when the customer wants to eat in, it is necessary to select and indicate the product to be eaten in advance before the checkout.

The eat-in selection process is a process of selecting an eat-in product from the food and drink products that are purchased products. FIG. 15 is a flowchart of the eat-in selection process. This process is executed by the mobile terminal 3 and the management server 2. When the eat-in selection process is performed, the purchased product list screen includes the eat-in selection button 81 as shown in FIG. The eat-in selection button 81 is a button that sends an eat-in selection request to the management server 2 by pressing the button and performs an eat-in selection process.

Basically, the customer registers the purchased product by the product selection process shown in FIG. 8, and when the eat-in selection button 81 is pressed on the purchased product list screen, the mobile terminal 3 executes the eat-in process. do.

First, the mobile terminal 3 determines whether or not the eat-in selection button 81 has been pressed (step S501). When the eat-in selection button 81 is not pressed (step S501; No), the mobile terminal 3 ends the eat-in selection process, returns to the purchased product list screen shown in FIG. 16, and performs the product selection process. On the other hand, when it is determined that the eat-in selection button 81 has been pressed (step S501), the mobile terminal 3 transmits an eat-in selection request to the management server 2 (step S501; Yes). When the management server 2 receives the eat-in selection request (step S502), the management server 2 refers to the purchased product list at that time, and selects the products to be eat-in from among the purchased products (hereinafter, referred to as "eat-in target products"). Extract (step S503). The eat-in target product is a product that can be eaten and eaten in the store 8, and can be arbitrarily set, and the product identification information of the product is associated with the eat-in target product in advance. The management server 2 generates an eat-in selection screen based on the extracted eat-in target product and transmits it to the mobile terminal 3 (step S504).

The mobile terminal 3 displays the received eat-in selection screen on the display unit 31 (step S505). FIG. 17 is a display example of the eat-in selection screen. In this example, the eat-in selection screen includes a message prompting the selection of the eat-in target product and input of the quantity, the eat-in display field 82, the quantity input field 83, the cancel button 84, and the confirmation button 85. The eat-in display field 82 includes a quantity input field 83 for inputting the name of the eat-in target product extracted from the purchased products and the quantity to be eat-in, and the number of purchased products already registered (hereinafter, “product quantity”). Call.) Is displayed. With such an eat-in selection screen, the customer can easily input "what and how many to eat in" from the purchased products. When the cancel button 84 is pressed, the screen returns to the purchased product list screen. When the confirmation button 85 is pressed, the quantity entered in the quantity input field 83 is confirmed as the number of eat-in target products.

In the quantity input field 83, the number of products to be eat-in (hereinafter referred to as "eat-in product") may be directly input by a number, or by tapping the name of the product to be eat-in in the eat-in display field 82, etc. The quantity change screen shown in FIG. 18 may be displayed, and the number of eat-in products may be input from the quantity change screen. FIG. 18 shows a display example of the quantity change screen displayed by tapping the focaccia in the eat-in display field 82. As shown in FIG. 18, the quantity change screen includes all buttons 86, quantity decrease button 87, quantity increase button 88, cancel button 89, change button 90, product quantity 91, and eat-in product quantity 92. including. The customer can increase or decrease the number of eat-in products 92 by pressing the quantity decrease button 87 or the quantity increase button 88. When the all button 86 is pressed, all of the product number 91 becomes the number of eat-in products 92. According to this, if the number of products is as large as "20" and the number of eat-in products is to be entered as "19", the customer presses all the buttons 86 and then the quantity decrease button. By pressing 87 once, "19" can be easily input, which is convenient. When the cancel button 89 is pressed, the screen returns to the eat-in selection screen. When the change button 90 is pressed, the screen returns to the eat-in selection screen, and the number in the quantity input field 83 is changed to the number of eat-in products 92 on the quantity change screen.

In this embodiment, "0" is set in advance for the quantity input field 83 on the eat-in selection screen and the number 92 of the eat-in products on the quantity change screen. However, the present invention is not limited to this, and any number can be set as long as the number of purchased items is not exceeded. If the customer wishes to cancel the product selected as the eat-in product later, the customer may change the number in the quantity input field 83 corresponding to the product selected as the eat-in product on the eat-in selection screen to "0".

In this embodiment, the quantity change screen is displayed as a pop-up screen when the name of the eat-in target product on the eat-in selection screen is tapped, and thus can be said to be a part of the eat-in selection screen. In the present embodiment, all the buttons 86 are included in the quantity change screen, but the present invention is not limited to this, and may be included in the eat-in selection screen.

In this way, the mobile terminal 3 selects the eat-in product on the eat-in selection screen and inputs the number of the eat-in products (step S506). The customer presses the confirmation button 85 in order to confirm the number of eat-in products. The mobile terminal 3 determines whether or not the confirmation button 85 has been pressed (step S507). If it is determined that the confirmation button 85 is not pressed (step S507; No), the mobile terminal 3 waits until the confirmation button 85 is pressed. On the other hand, when it is determined that the confirmation button 85 has been pressed (step S507; Yes), the mobile terminal 3 has the product identification information of the eat-in product in which a number "1" or more is input in the quantity input field 83 and the quantity input field. The number input to 83 and the number input to the management server 2 are transmitted as eat-in information (step S508).

The management server 2 receives the eat-in information from the mobile terminal 3 (step S509), and based on the product information DB 28, the tax-excluded price and the tax-included price of the eat-in product and the tax-excluded selling price for all the products in the purchased product list are excluded. The total amount including the subtotal and tax is calculated as the final price (step S510). Specifically, the management server 2 acquires the basic price of the eat-in product from the product information DB 28 based on the product identification information included in the eat-in information. Here, the basic price is a basic price when calculating the tax-included price, the subtotal, and the total amount, and is the tax-excluded price in this embodiment. The tax-included price is the tax-excluded price, which is the basic price, plus the consumption tax. It is assumed that the management server 2 stores information such as a standard tax rate related to consumption tax and a reduced tax rate applied to some target products in the storage unit 23 as tax rate information.

For example, suppose that the basic price of "Focaccia" selected as an eat-in product is "192 yen". Since the standard tax rate is applied to eat-in products, not the reduced tax rate, the management server 2 sets the tax-included price of "Focaccia" to be eat-in, for example, the price "211 yen" with 10% consumption tax. calculate. Since the reduced tax rate is applied to "Focaccia" that does not eat in, the tax-included price of "Focaccia" that does not eat in is, for example, the price "207 yen" in which 8% consumption tax is levied. Further, the management server 2 calculates the subtotal of the selling price excluding tax and the total amount including tax for all the products in the purchased product list based on the calculated price.

The management server 2 updates the purchased product list based on the calculated tax-excluded price and tax-included price of the eat-in product, and the subtotal of the selling price excluding tax and the total amount including tax for all the products in the purchased product list, and the mobile terminal 3 (Step S511). The mobile terminal 3 displays the received purchased product list as a purchased product list screen on the display unit 31 (step S512). As a result, the eat-in selection process ends. The customer continues to perform product selection processing and accounting processing from the purchased product list screen displayed on the mobile terminal 3.

FIG. 19 is a display example of the purchased product list screen after the eat-in product is selected. As shown in FIG. 19, the list display field 41 of the purchased product list screen displays the eat-in product icon 94 in association with the eat-in product. Since the quantity of the eat-in product is input on the eat-in selection screen, it is assumed that the corresponding quantity decrease button 47 and quantity increase button 48 do not exist.

According to this, the customer can easily select and confirm what to eat in among the purchased products. In addition, eat-in products are not subject to the reduced tax rate even if they are food and drink products, and the consumption tax of the standard tax rate is applied. If so, you can easily recognize it.

For convenience of explanation, the list display field 41 of the purchased product list screen shown in FIGS. 16 and 19 displays both the tax-excluded price and the tax-included price as the price of the product. In addition, the total amount of the selling price including tax for all the products in the purchased product list is calculated by taxing and totaling each product. However, the present invention is not limited to this, and the list display column 41 may display either the tax-excluded price or the tax-included price, and the total amount is subject to the subtotal of the products subject to the reduced tax rate and the standard tax rate. After calculating the subtotal of the products, each may be taxed and added up.

[Product selection process with change in selling price]
Next, a product selection process that involves a change in selling price will be described. The product selection process that involves a change in the selling price is a process that reflects the purchased product or the number of purchased products in the price, subtotal, and total amount on the purchased product list screen when they correspond to various discounts or discounts. In this case, basically, the customer registers the purchased product by the product selection process shown in FIG. 8, and performs the selling price change process described later at the timing when the purchased product list is updated. FIG. 20 shows a flowchart of a product selection process that involves a change in selling price.

In FIG. 20, the processes of steps S701 to S703, the processes of steps S705 to S709, and the processes of steps S711 to 713 other than the selling price change process are the processes of steps S201 to S203 and steps S204 to S208, respectively. Since the process of (1) and the process of steps S209 to S211 are the same, the description thereof will be omitted.
(Selling price change processing)
Next, the selling price change process will be described. The selling price change process is a process of determining whether or not a purchased product or a purchased quantity corresponds to various discounts or discounts, and changes the price if applicable. FIG. 21 is a flowchart of the selling price change process. This process is executed by the management server 2.

When the management server 2 receives the product identification information and the quantity from the mobile terminal 3 (steps S703 and S709 in FIG. 20), the management server 2 updates the purchased product list (step S601). Specifically, the management server 2 adds the product indicated by the received product identification information to the target purchased product list, and stores the updated purchased product list in the purchased product list DB 29. Then, the management server 2 determines whether or not the purchased product list meets any of the selling price change conditions indicated by the selling price change information 27 (step S602). In other words, the management server 2 determines whether or not any of the selling price change conditions shown in the selling price change information 27 is satisfied based on the product identification information and the number of purchased products shown in the purchased product list.

When the updated purchased product list does not meet any of the selling price change conditions indicated by the selling price change information 27 (step S602; No), the management server 2 ends the selling price change process and changes the selling price shown in FIG. Return to the accompanying product selection process. On the other hand, when the updated purchased product list corresponds to any of the selling price change conditions indicated by the selling price change information 27 (step S602; Yes), the management server 2 determines the discount or value associated with the corresponding selling price change condition. Based on the discount, the price, subtotal, and total amount of the products corresponding to the selling price change condition are calculated as the final price (step S603).

Specifically, the management server 2 acquires the basic price of the product corresponding to the selling price change condition from the product information DB 28, and the basic price, the purchased product list, and the discount rate or / / associated with the corresponding selling price change condition. And the discount amount, and the tax-excluded price of the product is calculated as the changed price. Further, the management server 2 is based on the calculated change price, tax rate information, and the purchased product list, and the tax-included price of the product, the subtotal of the selling price for all the products in the purchased product list, and the total amount including tax. And are calculated. That is, in this embodiment, the modified price obtained by applying the discount rate and / and the discount amount to the tax-excluded price, which is the basic price, is the tax-excluded price of the product, and the price obtained by taxing the consumption tax on the modified price is the product. It is a tax-included price. Then, the management server 2 ends the selling price change process and returns to the product selection process accompanied by the selling price change.

Here, the classification "Focaccia" to be discounted as the discount information by classification and the discount rate "10%" are associated with each other, and the selling price change process when two Focaccia are added to the purchased product list will be explained. do.

In the selling price change process, the management server 2 first receives the product identification information of "Focaccia" and the number of products from the mobile terminal 3 and updates the purchased product list. Then, the management server 2 determines whether or not the updated purchased product list meets any of the selling price change conditions indicated by the selling price change information 27 (step S602). At this time, the management server 2 determines that the selling price change condition of the discount by classification is satisfied (step S602; Yes). Therefore, the management server 2 calculates the price, subtotal, and total amount of "Focaccia" based on the discount information for each category (step S603).

Specifically, the management server 2 first acquires the basic price (for example, 192 yen) of "Focaccia" from the product information DB 28 based on the product identification information. The basic price is the tax-excluded price. Then, the management server 2 determines the discount amount (19 yen) and the changed price of "Focaccia" obtained by subtracting the discount amount from the basic price, that is, the discounted tax-excluded price (19 yen) based on the basic price and the discount information for each category. 173 yen) and. Further, since the management server 2 is subject to the reduced tax rate if it is a "Focaccia" to be taken out, the management server 2 calculates the discounted tax-included price (186 yen) in which the consumption tax (for example, 8%) is levied on the changed price. .. The management server 2 also calculates the subtotal and the total amount of the purchased product list based on the calculated price. In this way, the management server 2 calculates the discounted tax-excluded price and tax-included price of "Focaccia", and the subtotal and total price as the final price based on the discount information for each category.

Then, the management server 2 returns to the product selection process accompanied by the selling price change shown in FIG. 20, and updates the purchased product list based on the discounted tax-excluded price and tax-included price of "Focaccia", and the subtotal and total amount. , Send to the mobile terminal 3. FIG. 22 is a display example of the purchased product list screen including the products to which the discount by classification is applied. The mobile terminal 3 displays a purchased product list screen as shown in FIG. 22 based on the received purchased product list. As shown in FIG. 22, the list display field 41 on the purchased product list screen includes a message 96 indicating "10% discount (-19 yen)", a tax-excluded price "173 yen", and a tax-included price "186 yen including tax". And include.

In this way, when the purchase product is registered and the discount or discount based on the selling price change information 27 occurs, the management server 2 reflects the discount or discount on the purchased product list screen to be displayed thereafter. The price, subtotal, and total amount are displayed on the mobile terminal 3. As a result, the management server 2 can make the customer who uses the mobile terminal 3 recognize the accurate price at the present time. Further, the management server 2 can make the customer who uses the mobile terminal 3 preferably recognize the existence of the discount / discount by clearly indicating the amount of the price change on the purchased product list screen.

In the product selection process that involves changing the selling price, when the eat-in button 81 is pressed on the purchased product list screen, the mobile terminal 3 performs the eat-in selection process. At this time, in step S510 of the eat-in selection process shown in FIG. 15, the management server 2 first applies the discount and / and the discount corresponding to the basic price, that is, the changed price to which the discount and / and the discount is applied, that is, after the discount and / and the discount is applied. Calculate the tax-excluded price. Then, the management server 2 calculates the tax-included price, the subtotal, and the total amount after applying the discount and / and the discount of the purchased product based on the changed price. Specifically, in the above example of discount by classification of "Focaccia", if one of the two "Focaccia" is selected as an eat-in product, the management server 2 will be charged a reduced tax rate if it is an "Focaccia" to eat in. Therefore, the tax-included price (190 yen) in which the consumption tax (for example, 10%) is levied on the discounted tax-excluded price (173 yen) is calculated. Then, the management server 2 calculates the subtotal and the total amount of the purchased product list based on the calculated price. Further, the management server 2 updates the purchased product list and transmits it to the mobile terminal 3.

FIG. 23 is a display example of the purchased product list screen including the eat-in products to which the discount by classification is applied. Based on the received list of purchased products, the mobile terminal 3 has an eat-in product icon 94 and a message indicating "10% discount (-19 yen)" on the eat-in product "Focaccia" as shown in FIG. Display the purchased product list screen in which 96, the discounted tax-excluded price "173 yen", and the discounted tax-included price "190 yen including tax" are associated with each other.

In this way, in the eat-in selection process, the management server 2 calculates the price, subtotal, and total amount of the purchased product after applying the corresponding discount or discount. This is not limited to classified discounts, but applies to all discounts and discounts. For example, even if the basic price of "Focaccia" is 192 yen per piece, but if you buy two pieces together, the discounted tax-excluded price will be 350 yen, the management server 2 will have a bundle discount. After applying, calculate the price, subtotal, and total amount of the purchased product. At this time, the discounted tax-included price of the eat-in product is calculated by taxing the standard tax rate on the discounted tax-excluded price to which the bundle discount is applied. In other words, even if one of the two "Focaccia" purchased in bulk becomes an eat-in product, the bundle discount will be applied. Therefore, the mobile terminal 3 displays the purchased product list screen as shown in FIG. 24.

[Modification example]
