Description

  The present invention relates to a POS system.

  In general, retail stores such as supermarkets manage product sales information such as price and quantity using a POS (Point of Sales) system. In retail stores, for the purpose of attracting customers, a period may be set for a specific product by date and time, and a special sale may be performed to provide the product at a price lower than the price normally sold during that period. Conventional POS systems generally manage product sales information by setting the quantity and period of products for sale (see, for example, Patent Document 1).

That is, the values of these items may be added as reference information when setting products or quantities for sale.

[Special sale setting process]
A sale quantity setting process of the store controller 3 will be described.
Information necessary for setting the special sale quantity is input by the operator from the operation unit 33 of the store controller 3. The purchase information including the purchase cost and the purchase quantity and the special sale information including the special sale period, the special sale price, and the special sale quantity are input and set from the operation unit 33 of the store controller 3 and stored in the storage unit 32. .

It is assumed that the products for sale are selected in advance based on the result of considering the number of products in stock, the purchase plan, and the like. The sale price is determined based on data included in the purchase information file.
The CPU 31 sets, as a special sale quantity, a purchase quantity at the time of purchase at the lowest purchase cost among the purchase costs at which a special sale product fluctuates in a certain period. Note that if a product has already been sold when setting a special sale quantity, it is possible to prevent cost breakdown by setting the inventory quantity of the product as a special sale quantity. In addition, when confirming the change in the purchase cost, the target period is set manually or automatically, for example, as one month.
As another example, even if the CPU 31 is a method of summing the purchase quantities on the purchase date when the purchase cost of the special sale product in a certain period is equal to or less than the average purchase cost, and setting the value as the special sale quantity Good.

  The special sale quantity is not limited to the above example as long as it is set within a range in which the target profit can be secured in consideration of the purchase cost and the purchase quantity. In addition, although the example in which the special sale quantity is automatically calculated by the CPU 31 has been described, the store controller 3 may have a plurality of special sale quantity determination methods, and the operator may select one of the methods.

The store controller 3 transmits special sale information and information related to product registration to the POS register 2 before starting the special sale.
When the operator operates the store controller 3 as described above, the sale quantity and sale price for the sale target product are set.

[Special sales accounting]
The accounting process in each POS register 2 will be described with reference to the flowchart of FIG.
Step S701: When the accounting process is started, the POS register 2 reads the barcode attached to the product purchased by the customer by the scanner unit 20. The scanner unit 20 notifies the CPU 11 of a product code represented by the read barcode, and the product is registered in the POS register 2.
Step S703: It is determined whether or not the registered product is a special sale product. Specifically, the CPU 11 checks whether or not there is bargain information corresponding to the merchandise identification code of the registered merchandise. If there is bargain information corresponding to the registered merchandise, the CPU 11 displays the information. The extracted data is stored in the work area of the RAM 13, and the process proceeds to step S705. On the other hand, if there is no sale information for the registered product, the process proceeds to step S709.
Step S705: It is determined whether or not the remaining number of sale items is greater than or equal to the number of registered items. Specifically, the CPU 11 calculates the remaining number of the sale products from the sale quantity stored in the sale information and the sale price at the sale price with respect to the registered quantity, and the remaining number of the sale products is registered. If there are more than the quantity of the merchandise, the process proceeds to step S707. On the other hand, if the remaining number of sale items is smaller than the registered item quantity, the process proceeds to step S706.
Step S706: It is determined whether or not the remaining number of special sale quantities is one or more. Specifically, the CPU 11 checks whether there is one or more remaining merchandise registered, and if the remaining number is one or more, the process proceeds to step S708. On the other hand, if there is no remaining number of sale products for the registered product quantity, the process proceeds to step S709.
Step S707: The CPU 11 applies the normal price to the registered product.
Step S708: For the registered product, the CPU 11 applies the sale price to the remaining number of sale items and applies the normal price to the shortage.
Step S709: The CPU 11 applies the normal price to the registered product.
Step S711: The CPU 11 transmits the sales volume of the registered product to the store controller 3. The store controller 3 updates the sales quantity of the product in the sale file based on the received data.
Step S713: It is determined whether or not the product registration has been completed. Specifically, when the store clerk operation unit 15 receives a key input and the subtotal key is pressed, that is, when the product registration is completed, the CPU 11 proceeds to the process of step S715. On the other hand, if the product registration has not been completed, the CPU 11 returns to step S701 to register the next product.
Step S715: The CPU 11 performs a product settlement process. Specifically, the CPU 11 calculates the total purchase amount and purchase quantity of the products stored in the work area of the RAM 13. Next, the store clerk performs a settlement process such as cash delivery using the drawer 17 and the change machine 18 and issues a purchase statement (receipt) by the printing unit 19.

In the above description, the method of calculating the remaining number of sale items from the sale quantity stored in the sale information file and the sale quantity at the sale price has been described. However, the present invention is not limited to this, and data used for calculating the remaining number of sale items may be stored in another file. For example, the storage unit 32 of the store controller 3 stores a merchandise inventory master file, and the merchandise inventory master file indicates a “sale quantity” indicating the sales limit number of the special sale product, and a “sales quantity” indicating the sales performance number of the special sale product. Each item may be included.
As another example, each item of “sale quantity” indicating the sale limit number of sale items in the purchase information file stored in the storage unit 32 of the store controller 3 and “sales quantity” representing the number of sale results of sale items. May be included.
That is, the file for storing data used for calculating the remaining number of special sale products is not limited to the special sale information file.

The POS system 1 of the present embodiment can set the purchase quantity of the lowest purchase cost among the purchase costs for each purchase in a certain period as the special sale information when setting the special sale information. At this time, the special sale price is set based on the purchase price.
Alternatively, a purchase quantity at a purchase cost that is equal to or less than the average purchase cost calculated based on the purchase cost for each purchase in a certain period can be set as a special sale quantity. At this time, the special sale price is set based on the purchase price.
As a result of the above, special sales can be carried out without causing any disadvantages due to cost reduction in sales of special sales products.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design etc. of the range which does not deviate from the summary of this invention are included.
