  FIG. 8 is a flowchart showing an overview of the overall operation on the store terminal 2 side. First, in the input waiting state (step A1), the store terminal 2 performs processing for analyzing the input instruction content when detecting any input (steps A2 and A4). If an input instruction for registering sales data is detected (step A2), sales data registration processing is performed according to this input instruction (step A3).

  FIG. 9 is a flowchart showing the sales data registration process. First, the ECR terminal apparatus 3 determines whether the instruction content is a sales input (step B1) or a closing input instructed at the end of registration for one transaction (step B4). Here, if it is a sales input (step B1), the sales are registered based on the input sales data for each product, and the input sales data for each product is printed out on a receipt / journal or displayed. Data registration processing is performed (step B2). Then, corresponding to the registered product, “Date”, “Time”, “Store ID”, “Product Code”, “Character”, “Price”, “Number”, “Gross Profit”, “Inventory”, “Region ID” is stored in the sales log file 2-1 (step B3). In the case of a closing input (step B4), a normal closing process is performed to print the total amount, change, etc. on the receipt paper (step B5). Then, “sales date, time”, “store ID”, “transaction type”, “total sales”, and “tax” are stored in the transaction log file 2-2 (step B6).

  On the other hand, when a transmission instruction for various log files is input in step A4 in FIG. 8, the contents of the sales log file 2-1 and the transaction log file 2-2 are called and transmitted to the service surrogate server 1 (step A5). Here, on the service surrogate server 1 side, analysis processing of sales data, which will be described later, is performed based on the contents of each log file, and the analysis result is transmitted to the requesting store terminal 2. When the store terminal 2 receives the analysis result transmitted from the service surrogate server 1 side (step A6), the store terminal 2 displays and prints it (step A7).

  FIG. 10 is a flowchart showing an overview of the overall operation on the service surrogate server 1 side. First, it is determined whether or not data is exchanged with the store terminal 2 (step C1). When data is exchanged with the store side, the sales log file 2-1 and the transaction log file 2 are sent from the store terminal 2. -2 is transmitted (step C2). When the sales log file 2-1 and the transaction log file 2-2 are transmitted from the store terminal 2, each received log file is collected and based on the contents of each store according to time zone In addition to creating a sales database 4-1, a sales database by product 4-2 by store, and a sales database 4-3 by transaction by store, the sales by region based on the sales log file 2-1 sent from the store side The contents of the corresponding region in the product database 4-4 and the region-specific product database 4-5 are updated (step C3). Then, other sales analysis processing is executed (step C4).

  FIG. 11 is a flowchart showing the other sales analysis process described above. In this case, the sales analysis processing includes the sales database 4-1 by store, the sales database 4-2 by store, the sales database 4-2 by store, the transaction database 4-3 by store, and the sales by region. This is done by referring to the product database 4-4 and the region-specific product database 4-5. The service surrogate server 1 refers to the contents of the store-specific sales database 4-1 and compares the store sales data for each time zone to determine the best-selling time zone (step) D1) The message data that prompts the user to perform the time service in the best selling time zone is created (step D2). Next, referring to the contents of the store-by-product sales database 4-2, by comparing the store-by-product sales data, 10 products that are sold are extracted as the best-selling products (step D3). Message data including “product name” and “product code” of the best-selling product is created (step D4).

  Furthermore, by referring to the contents of the store-by-product sales database 4-2 and comparing the store-by-product sales data, 10 products with poor sales are extracted as dead products (step D5). Then, referring to the contents of the regional hot selling product database 4-4, 10 hot selling products are extracted from the product group belonging to the same store category in the same region (step D6). The sales database 4-2 by store is searched based on the hot selling products extracted in this manner, and it is determined whether or not the store has already sold hot selling products (10 items) (step D7). If there is, the “product name” and “product code” of the product are temporarily stored (step D8), and the score of the product being handled is obtained (step D9).

  Next, referring to the contents of the regional best-selling product database 4-4, regardless of the same region, the best-selling product of a different industry is discriminated (step D10), and the “product name”, “product” of the product is determined. "Code" is temporarily stored (step D11). Then, the contents of the temporary storage, that is, the products that are not handled among the best-selling products belonging to the same store category in the same region, the top-selling products of different industries regardless of the same region, and the deadly products are exchanged. The message data recommending the power is created (step D12). Then, a billing procedure for billing for the sales analysis agent is performed (step D13).

  Read sales data by time, transaction, and product corresponding to the store from the sales database 4-1 by store, sales database 4-2 by store, and sales database 4-3 by transaction To the requesting store terminal 2 (step D14). And various messages created as described above, that is, a message urging that the time service should be performed during the best-selling time in the store, a message of the best-selling product in the store, and a message recommending replacement of the product The request is transmitted to the requesting store terminal 2 (step D15). Thereafter, each transmitted data is cleared (step D16).

  As described above, in this embodiment, the service surrogate server 1 collects sales data of each store transmitted from each store terminal 2 via the Internet 3, and collects the sales data of each store and one target store. Is compared with the sales data transmitted from the store terminal, and based on the compared result, it is determined whether or not the product sold at the target store is appropriate, and a message indicating the determined determination result is displayed. Since the information is transmitted to the store terminal 2 of the target store, it can be determined whether or not the product sold in the store is appropriate, and the determined determination result can be reported to the store.

  In addition, the sales analysis processing performed on the service surrogate server 1 side calculates a sales total for each aggregation type of sales data by time zone, product, etc., and generates a report that analyzes the total sales for each aggregation type. Create or give advice on sales strategy according to the analysis result, that is, find a dead product, advise the best selling product instead of this dead product, aggregate sales data by time zone, and sell In search of the time zone, you can advise the best selling time zone. In this case, when advising a hot selling product as a substitute for a dead product, it is possible to advise a hot selling product in consideration of the regional characteristics to which the store belongs. As a result, the store side can know the analysis results of other stores in the same region in addition to the sales analysis results of its own store, which can be used as effective materials for improving sales, It becomes possible to improve sales accurately.

  In the above-described embodiment, as the sales analysis processing at the store unit, the product-based aggregation, the time zone-based aggregation, and the transaction-based aggregation are performed. You may make it perform the total according to genre. That is, the content of sales analysis is arbitrary, and any kind of sales analysis may be performed. The same applies to sales analysis of other stores in the same region and sales analysis of other regions. In addition, the sales analysis may be performed by collecting sales data of the store at a time arbitrarily designated by the registered member user, not limited to the case where the sales analysis is periodically performed. That is, sales analysis may be performed according to the request of the registered member user, and the analysis result may be transmitted as a report message.

  In the embodiment described above, as a sales analysis process for each region, a hot selling product in the same-sector store or a different industry store in the region is identified and a report message is created. Among them, it is possible to identify a hot selling product in the same store category in a designated area arbitrarily designated by a registered member user and create a report message thereof. For example, in order to investigate a consumption trend of a shopping street or a busy shopping street that is in a competitive relationship, a shopping street or a busy shopping street that is in a competitive relationship may be designated and the analysis result may be obtained.

  Further, only the sales analysis arbitrarily designated by the registered member user from various sales analysis menus prepared in advance may be performed. In other words, in addition to product-based totals, time-based totals, and transaction-based totals, you may select and specify the desired sales analysis from among weekly, monthly, and period-by-unit aggregation processes, and product-genre aggregation. Good. In addition, when billing an agency fee for sales analysis to each member store, the amount charged to the store may differ depending on what kind of sales analysis the registered member user requested. . That is, a billing method according to the type of sales analysis, the number of analyzes, and the amount of data to be analyzed may be adopted.

  Further, on the service provider side, sales analysis may be executed in accordance with the purchaser's age condition, sex condition, etc. in addition to the district condition. That is, sales analysis may be performed in consideration of the purchaser's age, sex, and the like. In this case, the store side inputs the district conditions to be analyzed, the purchaser's age conditions, gender conditions, etc. from the store side to the service provider side, and the service provider side executes the sales analysis according to the input conditions. May be instructed. Furthermore, when performing sales analysis according to district conditions, purchaser's age conditions, and sex conditions, relaxation of the conditions may be instructed from the store side.

  On the other hand, the computer provided in the service surrogate server 1 collects the sales data of each store transmitted from the store terminal 2, and the collected sales data of each store and the sales data transmitted from the store terminal of one target store And a message indicating the discrimination result discriminated by the discriminating means, discriminating means for discriminating whether or not the product sold at the target store is appropriate based on the comparison result compared by the comparing means May be provided as a transmission means for transmitting the information to the store terminal 2 of the target store.
