[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiment.

[0017] [1. Overview] First, an overview of the present invention will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of a conventional cost accounting process.

[0018] Previously, the actual cost of goods was calculated and managed based on inventory data, and the system accounting year and month was updated after the monthly closing process, and cost accounting was performed daily. Also, previously, the inventory valuation unit price of goods was calculated by running the cost accounting process, which aggregated and calculated the latest inventory receipt and payment data for the current month of the system accounting year and month, and the sales cost data of the sales data was updated based on the calculated inventory valuation unit price, allowing the gross profit based on the actual cost to be understood.

[0019] In this way, in the past, the inventory valuation unit price was calculated based on the confirmed inventory data of the previous month and the receipt and payment data of the current month, so in terms of operation, the system accounting year and month differed from the actual year and month until the monthly closing work was completed, so the cost for that period could not be calculated, and as a result, the cost was different or could not be obtained, so daily gross profit could not be confirmed. Furthermore, in the past, if there was a large amount of backlog of orders for the current month, the final inventory valuation unit price and inventory amount were not known until sales and purchases were confirmed, so manual data processing was required to forecast the final amount.

[0020] For example, as shown in Figure 1, previously, monthly closing operations and closing processing for the current month were carried out within five business days from the end of the month, and even if the actual year and month was January 2020 and the accounting year and month in the system was December 2019, and products scheduled to be purchased at the end of the month were often purchased across months (due to the effects of overseas transactions, etc.), because the monthly closing operations for December 2019 had not been completed, the inventory amount at the end of December 2019 had not been determined, and cost calculations for January 2020 taking into account the backlog of orders scheduled for January 2020 were not performed (black circles in the figure), it was not possible to confirm daily trading results and gross profit as management indicators, and it was not possible to predict the outcome of transactions.

[0021] Therefore, in this embodiment, a mechanism is provided that allows for timely understanding of costs and profits by performing cost calculations by referring to the latest data at that time, even before the previous month's inventory data is finalized.

[0022] [2. Configuration] An example of the configuration of the cost calculation device 100 according to this embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of the configuration of the cost calculation device 100 in this embodiment.

[0036] [3. Specific Examples] A specific example of this embodiment will be described with reference to FIGS.

[0037] [Cost calculation process] An example of the next month's cost calculation process in this embodiment will now be described with reference to Fig. 3. Fig. 3 is a flowchart showing an example of the process of the cost calculation apparatus 100 in this embodiment.

[0038] As shown in FIG. 3, the order acquisition unit 102a acquires order data that sets the number of products ordered in the current month and the order amount for the current month before the monthly closing process is completed, and registers the order data in the transaction database 106a (step SA-1).

[0039] Then, before the monthly closing process is completed, the order acquisition unit 102b acquires order data that sets the order quantity and order amount of the product for that month, and registers the order data in the transaction database 106a (step SA-2).

[0040] Then, the purchase schedule acquisition unit 102c acquires purchase schedule data that sets the current month's purchase quantity of the product, the current month's purchase amount, and the current month's expenses based on the order data, and registers the purchase schedule data in the transaction database 106a (step SA-3).

[0041] Then, before the monthly closing process is completed, the inventory acquisition unit 102d acquires the previous month's inventory data, which includes the inventory quantity and inventory amount of the product at the end of the previous month, as preliminary values, and registers the previous month's inventory data in the transaction database 106a (step SA-4).

[0042] Then, the inventory valuation unit price calculation unit 102e uses the sum of the inventory amount at the end of the previous month, the purchase amount for this month, the expenses for this month, and the order amount for this month as the dividend, and uses the sum of the inventory quantity at the end of the previous month, the purchase quantity for this month, and the order quantity for this month as the divisor, calculates the quotient as a preliminary inventory valuation unit price value, and registers the preliminary inventory valuation unit price value in the transaction database 106a (step SA-5).

[0043] Then, the inventory acquisition unit 102d sets the inventory quantity at the end of the current month for the product as the sum of the inventory quantity at the end of the previous month and the purchase quantity for the current month minus the number of orders for the product for the current month, acquires inventory data at the end of the current month in which the product of the preliminary inventory valuation unit price and the inventory quantity at the end of the current month is set as the inventory amount at the end of the current month, and registers the inventory data at the end of the current month in the transaction database 106a (step SA-6).

[0044] Then, when the monthly closing process is completed, the inventory acquisition unit 102d acquires the previous month's inventory confirmation data, which sets the previous month's inventory confirmation quantity and the previous month's inventory confirmation amount of the product, and registers the previous month's inventory confirmation data in the transaction database 106a (step SA-7).

[0045] Then, the inventory valuation unit price calculation unit 102e uses the sum of the confirmed inventory amount at the end of the previous month, the purchase amount for the current month, and the expenses for the current month as the dividend, and uses the sum of the confirmed inventory quantity at the end of the previous month and the purchase quantity for the current month as the divisor to calculate the inventory valuation unit price, and registers the inventory valuation unit price in the transaction database 106a (step SA-8), and terminates the processing.

[0046] An example of the cost calculation process in this embodiment will now be described with reference to Figures 4 and 5. Figures 4 and 5 are diagrams showing an example of the cost calculation process in this embodiment.

[0047] As shown in FIG. 4, in this embodiment, in a company that performs monthly closing processing for the previous month within 5 business days from the end of the month, in early January 2020 (before the completion of monthly closing processing for December 2019), "inventory valuation unit price = (inventory confirmed amount at the end of the previous month + purchase amount for this month + overhead amount for this month) / (confirmed inventory at the end of the previous month + purchase amount for this month)" is calculated, "inventory at the end of the current month = inventory at the end of the previous month + purchase amount for this month - sales amount for this month" is calculated, and "inventory amount at the end of the current month = inventory valuation unit price × inventory at the end of the current month" is calculated, and the cost calculation process at the end of the current month (December 2019) is performed in the accounting system. Here, as shown in FIG. 4, in this embodiment, the purchase amount for this month, purchase amount for this month, overhead amount for this month, and sales amount for this month may be reflected in the monthly inventory table each time each input process (purchase input, purchase overhead input, sales input, etc.) is performed.

[0048] Furthermore, as shown in Figure 5, in this embodiment, at the beginning of January 2020 (before the monthly closing process for December 2019 is completed), the accounting system obtains the end-of-month inventory quantity and end-of-month inventory value for the current month (December 2019) as preliminary values, and these are registered in the monthly inventory table as preliminary values ​​for the end-of-previous month inventory quantity and end-of-previous month inventory value for January 2020. As shown in FIG. 5, in this embodiment, the order quantity and order amount for this month, which are scheduled to be purchased in January 2020, are obtained from the order table, and the calculation is "provisional inventory valuation unit price = (inventory amount at the end of the previous month + purchase amount for this month + general expenses for this month + order amount for this month) / (inventory quantity at the end of the previous month + purchase quantity for this month + order quantity for this month)". The order quantity for this month, which is scheduled to be sold in January 2020, is obtained from the order table, and the calculation is "inventory quantity at the end of this month = inventory quantity at the end of the previous month + purchase quantity for this month - sales quantity for this month". The inventory quantity and inventory amount at the end of this month are reflected as preliminary values ​​in the monthly inventory table. In this way, in this embodiment, the data (order amount and order quantity for this month) included in the actual year and month (January 2020) of the planned purchase date in the order table may be included in the calculation of the preliminary inventory valuation unit price.

[0049] In this embodiment, the monthly closing process is completed on January 8, 2020, and the accounting system year and month (accounting year and month) becomes the actual year and month, January 2020, and the monthly inventory data for the previous month (December 2019) is finalized. Therefore, cost calculation processing is performed at any time using the finalized inventory amount and finalized inventory quantity of the product at the end of the previous month.
