These records are inventory data. The control unit 232 of the store computer 230 stores the number of sales corresponding to each product code included in the record of the sales table classified by time zone, which is sales data classified by time zone, which will be described later. Update based on data. In this way, the control unit 232 manages the inventory quantity of each product on the inventory table T5.

  FIG. 6 shows an example of the sales table by time zone T2. In the sales table by time zone T2, records of date, time zone number, cash register number, unit price, sales point, and discount amount are recorded in association with the product code. These records are sales data by time zone. The sales data by time zone is data in which each product code is associated with the number of sales by time zone and by sales unit price. Such sales data by time zone is generated based on the sales data in which the product code generated by the POS terminal 210 for each transaction, the selling unit price, and the sales generation time correspond to each other. That is, the time zone is specified by referring to the sales generation time generated for each transaction by the POS terminal 210, and the number of sales based on the number of sales data of the same product code and the same unit price within the time zone. Is required. Sales data for each time zone is generated based on the time zone and the number of sales determined in this way.

  As shown in FIG. 6, when a plurality of types of selling unit prices are set in the same time zone, a record of sales data by time zone is generated for each selling unit price. In the example shown in FIG. 6, the record whose time zone number (No.) is “17” (indicating time 16: 00 to 17:00) has a selling price of “100” and a selling price of “90”. Two types of records have been generated.

  Here, as an example, the record recorded in the sales table by time zone T2 is generated based on the sales data generated by the POS control unit 212 of the POS terminal 210, and transmitted to the store computer 230 via the LAN 250. Recorded in the store computer 230. The flowcharts shown in FIGS. 11 and 12 show the contents of processing in the POS control unit 212 of the POS terminal 210 and processing in the control unit 232 of the store computer 230 at that time. As another example, the POS terminal 210 transmits sales data to the store computer 230 via the LAN 250, and records recorded in the sales table by time zone T2 based on the sales data received by the control unit 232 of the store computer 230. May be generated.

  FIG. 7 shows an example of the unit price sales table T3. In the unit sales table T3, records of register numbers, product codes, unit sales prices, sales amounts, and sales points are recorded in association with dates.

  FIG. 8 shows an example of the sales tabulation table T4 by time zone. As described above, the sales tabulation table by time zone T4 corresponds to the product code, and includes the date, time zone number, unit price, discount width, sales point, sales amount, discount point, discount amount, and rough amount. A record of interest is recorded. These records are sales summary data by time zone. Such a record of the sales summary table by time zone T4 is generated by the control unit 232 of the store computer 230 through a summary process based on the records of the sales table by time zone T2. That is, the control unit 232 aggregates the sales unit price, the sales point, and the discount amount data for all the register numbers in the same time zone for the same product code, and records the data in the time zone sales summary table T4. Then, the control unit 232 generates and records a record of discount width, sales amount, discount points, and gross profit based on the record thus recorded.

  Next, the control unit 232 of the store computer 230 determines, for each individual product specified by the product code, based on the record recorded in the time-based sales summary table T4 and the record recorded in the inventory table T5. Display data indicating the number of sales by time zone and by sales price is generated, and the generated display data is displayed on the display 235. The display data is generated as tabular data in which time zones and selling unit prices are expressed in a matrix format and the number of sales is positioned at the intersection of these time zones and selling unit prices. A sales analysis screen is displayed on the display 235 based on such display data.

  FIG. 9 shows an example of a sales analysis screen displayed on the display 235 of the store computer 230. In the sales analysis screen shown in FIG. 9, a product code, a product name, and the current inventory quantity are displayed as information about the product that is the target of the sales analysis screen. These various records are displayed by quoting the records recorded in the inventory table T5. In the example illustrated in FIG. 9, the product code is “49XXXX1”, the product name is “product A”, and the current stock quantity is “10”.

  In the sales analysis screen shown in FIG. 9, the time axis is assigned to the horizontal axis (row), the date and the unit price are assigned to the vertical axis (column), and each individual unit price includes a total score and amount. And gross profit is allocated. And at the intersection of the time zone and selling unit price (score, amount, gross profit), the number of sales for each time zone, the amount of sales total amount, the gross amount of gross margin A record is displayed. These various records relating to unit sales prices etc. are displayed by quoting the records recorded in the sales tabulation table T4 by time zone.

  Then, the control unit 232 of the store computer 230 calculates the total value of all the time zones by calculating the number of sales (points), the total sales amount (amount), and the gross profit total amount (gross margin) in each selling unit price. The total is displayed on the sales analysis screen shown in FIG. For example, the total number of sales (points), total sales amount (amount), and gross profit total amount (gross margin) sold at a fixed price of 100 yen on July 20 are “105” and “10500”, respectively. , “5250”.

  Similarly, the control unit 232 of the store computer 230 obtains the total value of the number of sales (points), the total amount of sales (amount), and the total amount of gross profit (gross margin) for each time period. It is displayed as a total on the sales analysis screen shown in FIG. For example, the total of the number of sales (points), total sales amount (amount), and gross profit total amount (gross margin) sold in the time zone from 11:00 to 12:00 on July 20 is “20 ”,“ 2000 ”, and“ 1000 ”.

  In addition, the control unit 232 of the store computer 230 calculates the total number of discarded points (points) for the discarded items, the sales amount (amount) when the product is sold, and the gross amount (gross margin). The value is also displayed on the sales analysis screen. Of these, the gross profit is the amount of loss caused by disposal.

  FIG. 10 shows an example of a message displayed on the display 235 of the store computer 230. This message is composed of a character string indicating the ratio of the sales score to the inventory quantity in a certain time zone, and a predetermined warning message displayed when the ratio is equal to or less than a preset reference value. In this example, “6% of the inventory has been sold” and “Warning: some of the inventory may be disposed of” are displayed. Here, for example, it is assumed that 10% is set as the reference value.

  FIG. 11 is a flowchart showing the processing procedure of the POS terminal 210. Hereinafter, the processing procedure of the POS terminal 210 will be described with reference to the flowchart of FIG. First, in step S1, the POS control unit 212 is stored in the hard disk drive (HDD) 219 based on sales data for each customer (consisting of a product code, a selling price, a sales score, etc. of the sold product). Records are added and updated to the sales table by time zone T2 shown in FIG.

  Next, in step S2, it is determined whether or not the current time has reached a preset transmission time. As a result, when it is determined that the current time is not the transmission time, the process returns to step S1, and the processes after step S1 are repeatedly executed. On the other hand, if it is determined that the current time is the transmission time, the process proceeds to step S3.

  In step S 3, under the control of the POS control unit 212, unsent data in the sales table by time zone T 2 is read from the hard disk drive device (HDFD) 219 via the I / O device control unit 213 and sent via the bus 220. The data is transmitted to the store computer 230 via the LAN 250 under the control of the communication interface (I / F) 211.

  Next, in step S4, it is determined whether or not the end of the process is instructed by turning off the power of the POS terminal 210 or the like. As a result, when it is determined that the end of the process is not instructed, the process returns to step S1 and the processes after step S1 are repeatedly executed. On the other hand, if it is determined that the end of the process has been instructed, the present process ends.

  FIG. 12 is a flowchart showing the processing procedure of the store computer 230. First, in step S21, the control unit 232 determines whether or not the data of the sales table classified by time zone T2 has been transmitted from the POS terminal 210 via the LAN 250. As a result, when it is determined that the data of the sales table by time zone T2 has not been transmitted from the POS terminal 210 via the LAN 250, the process returns to step S21, and the processes after step S21 are repeatedly executed. On the other hand, if it is determined that the data of the sales table by time zone T2 has been transmitted from the POS terminal 210 via the LAN 250, the process proceeds to step S22.

  In step S 22, under the control of the control unit 232, the data of the sales table by time zone T 2 is received by the control of the communication interface (I / F) 231 and stored in the hard disk drive device (HDD) 239. The record of the sales table T2 is updated.

  Next, in step S23, under the control of the control unit 232, the sales summary table by time zone T4 (FIG. 8) is generated or updated based on the sales table by time zone T2 and the product master table T1.

  Next, in step S24, display data for displaying the sales analysis screen as shown in FIG. 9 is generated under the control of the control unit 232 based on the sales summary table T4 and the inventory table T5 according to time zones. And displayed on the display 235.

  Next, in step S <b> 25, under the control of the control unit 232, the ratio of the sales score to the inventory quantity is calculated and displayed on the display 235. For example, at time 11:00, the number of stocks before sales of 10 sales points is 175 with respect to 10 sales points, so the ratio of the sales points to the number of stocks is about 6 (= 10/175 × 100). % (Percent).

  Next, in step S26, it is determined whether or not the ratio of the sales score to the inventory quantity is equal to or less than a preset reference value. As a result, when it is determined that the ratio of the sales score to the inventory quantity is not equal to or less than the reference value, the process returns to step S21, and the processes after step S21 are repeatedly executed. On the other hand, when it is determined that the ratio of the sales score to the inventory quantity is below the reference value, the process proceeds to step S27, and a warning message as shown in FIG.

  FIG. 10 shows an example in which the ratio of the sales score to the stock quantity and the warning message are displayed in another window displayed on the screen, but a predetermined display area in the sales analysis screen shown in FIG. And the ratio of the sales score to the inventory quantity and a warning message may be displayed in the area.

  Next, the process proceeds to step S28, where it is determined whether or not the end of the process is instructed by turning off the power of the store computer 230. As a result, it is determined that the end of the process is not instructed. Then, the process returns to step S21, and the processes after step S21 are repeatedly executed. On the other hand, if it is determined that the end of the process has been instructed, the present process ends.

  As described above, according to the present embodiment, based on the sales data transmitted from the POS terminal 210 to the store computer 230, the display 235 of the store computer 230 displays the sales analysis as shown in FIG. Since the screen is displayed, the user (store manager) can easily grasp the number of sales by product and by sales price for each time zone. Further, discount consideration can be started promptly by a warning message. Therefore, when it is desired to sell out a product with a expiration date within the expiration date, it becomes possible to determine the discount timing and the discount amount relatively easily based on the display contents of the sales analysis screen and the warning message. .

  After determining the discount timing and discount amount for a certain product, the store manager actually updates the current unit price of the product in the product master table T1 and executes the discount. The current unit price corresponds to the selling unit price. In this way, it is possible to set a price that increases the profit while reducing the occurrence of unsold as much as possible.

  It should be noted that the configuration and operation of the above-described embodiment are examples, and it goes without saying that they can be changed as appropriate without departing from the spirit of the present invention. The specific numerical values and names used in the above embodiments are examples and are not limited to these.
