The storage unit 12 stores various programs for causing the control unit 13 to function. The storage unit 12 stores a plurality of past invoice data in which product names described in a plurality of invoices issued or received in the past are associated with at least one of unit price and quantity.

FIG. 3 is a diagram showing an example of the data structure of past invoice data stored in the storage unit 12. As shown in FIG. FIG. 3A shows an example of the data structure of received past bill data stored in the storage unit 12, and FIG. 3B shows an example of the data structure of issued past bill data stored in the storage unit 12. An example is shown for each. In the received past invoice data shown in FIG. ” and “details” are associated with each other. "Breakdown" includes "product name", "unit price" and "quantity" to be billed on the invoice. A single past invoice data may contain a plurality of breakdowns. In the issued past invoice data shown in FIG. 3(b), "issued to", "issued invoice number", "bill issue date", and "billing amount" indicating the business operator to which the invoice data is addressed. and "breakdown" are associated with each other. The past invoice data may further include consumption tax amount, tax rate, transfer account information, and the like.

It should be noted that the storage unit 12 may store invoice data that has been sent and received in the past by other companies other than one's own company as past invoice data. In this case, bill data is stored in which the information indicating the business operator has been processed so that the business operator of the bill issuer and recipient cannot be specified.

The control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 functions as an acquisition unit 131 , a specification unit 132 and a display processing unit 133 by executing control programs stored in the storage unit 12 .

[Abnormality determination process]
Abnormality determination processing in the information processing apparatus 1 will be described. The acquisition unit 131 acquires invoice data including the product name and at least one of the unit price and quantity. FIG. 4 is a diagram showing an example of invoice data acquired by the acquisition unit 131. As shown in FIG. Invoice data includes, for example, the name of the issuing company, the issuing company number, the invoice number, the date of issue, the name of the receiving company, the receiving company number, the billing amount, the transfer account information, and the details of the billing object. include. The breakdown of billable items includes, for example, the product name, unit price, quantity, subtotal billed amount for each product name, and consumption tax amount to be billed in the invoice data. Note that when the bill data is bill data of a bill to be issued, the obtaining unit 131 may obtain bill data that does not include the bill number and issue date. Whether the bill data is scheduled to be issued or has already been received may be determined, for example, based on the sender of the bill data.

The identifying unit 132 identifies one or more unit prices or quantities associated with the product name included in the invoice data in past invoice data. The identifying unit 132 identifies the product name included in the acquired invoice data as the product name to be determined. If the invoice data includes multiple product names, each of the multiple product names may be specified as the product name to be judged. For example, when acquiring the invoice data shown in FIG. 4, the specifying unit 132 specifies that the product A and the product B included in the acquired invoice data are the product names to be determined.

Then, using the identified product name as a search key, the identification unit 132 extracts invoice data that includes the same product name in the past invoice data, Identify the associated unit price or quantity.

The identification unit 132 may select past bill data to be searched according to whether the bill data obtained is received bill data or bill data to be issued. That is, when the identification unit 132 acquires bill data issued by another business from an accounting processing device used by another business, the identification unit 132 searches past received bill data, When bill data scheduled to be issued is obtained, past bill data that has already been issued may be searched.

The display processing unit 133 causes the external device to display predetermined information when the relationship between the unit price or quantity included in the invoice data and the one or more unit prices or quantities identified by the identifying unit 132 satisfies a predetermined condition. . The display processing unit 133 compares the unit price or quantity associated with the product name included in the acquired invoice data with the unit price or quantity specified by the specifying unit 132, and determines whether or not a predetermined condition is satisfied. do. Predetermined conditions will be described later. Then, when the predetermined condition is satisfied, the display processing unit 133 causes the information terminal 2 to display the screen shown in FIG.

FIG. 5 is a diagram showing an example of a screen displayed by the display processing unit 133. FIG. In FIG. 5, a warning message is displayed to warn that the unit price or quantity of the product deviates from past data. The screen shown in FIG. 5 further includes a button labeled "Confirm" and a button labeled "OK". When the user presses a button labeled "confirm", the display processing unit 133 further displays a screen (described later) for displaying information contained in the past invoice data. When the button labeled "OK" is pressed, the screen shown in FIG. 5 is closed.

By configuring the information processing device 1 in this way, the business that issues or receives the invoice can confirm the validity of the information included in the invoice data. In particular, the information processing device 1 is configured to determine the validity of information at the timing of receiving invoice data or at the timing of acquiring invoice data to be issued. A person can prevent the issuance of invoices with erroneous contents or accounting processing based on erroneous invoices.

An example of judgment processing will be explained. The display processing unit 133 displays the unit price or quantity included in the invoice data, and the average or median value of one or more unit prices or quantities associated with the product name included in the invoice data in one or more past invoice data. , satisfies a predetermined condition, predetermined information is displayed on the external device. The display processing unit 133 calculates the average value or median value of one or more unit prices or quantities associated with the same product name in the past invoice data specified by the specifying unit 132 . Then, it is determined whether or not the relationship between the unit price or quantity associated with the product name included in the invoice data and the calculated average value or median value satisfies a predetermined condition.

The display processing unit 133 causes the external device to display predetermined information when a predetermined condition is satisfied that the ratio of the unit price or quantity included in the invoice data to the calculated average value or median value is equal to or greater than a predetermined value. may The predetermined value is set, as an example, based on the fluctuation range that is considered to be no more divergent due to the nature of the transaction. As an example, the predetermined condition is that the ratio of the unit price or quantity to be determined to the average value or median value of the calculated unit price or quantity is 150% or more or 50% or less.

If the amount of change in quantity or unit price can be predicted in advance, the predetermined condition may be set by the absolute value of the difference between the specified unit price or quantity and the calculated average or median value of the unit price or quantity. That is, the display processing unit 133 transmits predetermined information to the external device when a predetermined condition is satisfied that the difference between the unit price or quantity included in the invoice data and the calculated average value or median value is equal to or greater than a predetermined value. may be displayed.

By the way, since the trading volume and trading price fluctuate depending on the nature of the product, if the information processing device 1 is configured so that different predetermined conditions can be given for each product, it will be easier to detect abnormal transactions. information can be provided to the user.

In this case, the storage unit 12 stores the product name and the predetermined condition in association with each other. As an example, for products with small fluctuations in transaction volume or price, the storage unit 12 states that "the quantity or price of the product to be judged deviates from the specified unit price or the average value or median value of the quantity by 20% or more." Memorize the condition. On the other hand, for products with large fluctuations in transaction volume or price, the storage unit 12 stores the value of 50 of the average value or median value based on the average value or median value of the unit price or quantity specified by the quantity or price of the product to be judged. % or more" is stored.

Then, the display processing unit 133 determines that the relationship between the unit price or quantity and the average value or median value included in the invoice data is stored in the storage unit 12 in association with the product name included in the invoice data. If the conditions are satisfied, predetermined information may be displayed on the external device. The display processing unit 133 acquires a predetermined condition associated with the product name included in the invoice data in the storage unit 12 . Then, the display processing unit 133 determines whether or not the relationship between the unit price or quantity included in the invoice data and the average value or median value of the calculated unit price or quantity satisfies the acquired condition.

For example, if the upper limit or lower limit of the price or quantity is predetermined, the storage unit 12 stores the product name and the unit price or quantity to be determined as being larger than the upper limit value or smaller than the lower limit value of the price or quantity. You may store the condition that Then, the display processing unit 133 displays predetermined information when the quantity or amount of the product included in the invoice data is greater than the upper limit value or less than the lower limit value stored in the storage unit 12 in association with the product name. Display it on an external device.

In addition, depending on the product, the trading volume and price fluctuation range may vary depending on the time. Therefore, the storage unit 12 may store predetermined conditions in association with product names and times. As an example, the storage unit 12 may store a predetermined condition when product A is traded in December and a predetermined condition when product A is traded at other times. Then, the display processing unit 133 sets a predetermined condition used for determination based on the product name included in the invoice data and the date of issue associated with the acquired invoice data or the date on which the information processing apparatus 1 performs determination. Acquired from the storage unit 12 . Then, the quantity or unit price included in the invoice data is compared with the specified unit price or quantity, and it is determined whether the acquired predetermined condition is satisfied. By configuring the information processing device 1 in this way, it is possible to determine an abnormality based on a predetermined rule set in view of the property of the product, and improve the accuracy of determination.

By the way, the transaction volume and transaction price of products may differ depending on the counterparty of the transaction. Therefore, the information processing apparatus 1 may be configured to determine whether or not there is an abnormality in the unit price or quantity based on different conditions depending on the other party.

The storage unit 12 stores a plurality of past invoice data in which the product name, at least one of unit price or quantity, invoice issue time, and invoice issuer or recipient are associated. In other words, the storage unit 12 stores the past bill data further associated with the destination business operator or the issuing business operator of the bill. Past invoice data includes, for example, the business name or business number of the destination business or the issuing business. The storage unit 12 stores the issuer or destination of the bill in association with a predetermined condition. That is, the storage unit 12 stores different predetermined conditions for each trading partner even for the same product.

The display processing unit 133 stores the relationship between the unit price or quantity included in the invoice data and the calculated average value or median value in the storage unit 12 in association with the issuer or destination of the invoice corresponding to the invoice data. When the predetermined condition is satisfied, predetermined information is displayed on the external device. The display processing unit 133 identifies the issuer business operator or destination business operator associated with the acquired invoice data. Then, the display processing unit 133 acquires a predetermined condition stored in association with the issuing company or the destination company. Then, the display processing unit 133 determines whether the unit price or quantity included in the acquired invoice data satisfies a predetermined condition.

The information processing device 1 may determine whether there is an abnormality in the unit price or quantity based on different conditions depending on the issuer or destination of the invoice and the product. In this case, the storage unit 12 stores the predetermined conditions in association with the issuer or destination of the bill and the product. Then, the display processing unit 133 acquires a predetermined condition stored in the storage unit 12 in association with the issuing company or destination company associated with the invoice data including the unit price or quantity to be determined, and the product, Determine whether the unit price or quantity included in the acquired invoice data satisfies the acquired conditions.

By the way, there are cases where the upper limit of the unit price is set in advance in the contract. In such a case, the information processing device 1 may be configured to determine abnormalities in the unit price or quantity based on the transaction conditions defined in the contract.

In this case, the storage unit 12 stores contract data including terms of trade with multiple businesses. As an example, the contract data includes the destination business name, destination business number, contract date, business name, business number, address or telephone number of the business placing the order, and transaction conditions. The terms of trade include the traded product name, unit price, or quantity. As an example, the storage unit 12 may store contract data in which a different unit price is set for each traded quantity as terms of trade. For example, when the quantity of commodities to be traded is 100 or more and less than 200, the storage unit 12 may store contract data in which a higher unit price is set than in the case of trading of 200 or more and less than 300. Further, the storage unit 12 may store contract data in which different unit prices are set according to transaction amounts. As an example, the storage unit 12 may store contract data in which a larger unit price is set for a transaction of 100,000 yen or more and less than 1 million yen than for a transaction of 1 million yen or more and less than 5 million yen.

The display processing unit 133 may display predetermined information on the external device when the unit price or quantity included in the invoice data does not satisfy the transaction conditions included in the contract data. The display processing unit 133 identifies contract data to be referred to according to the product name, quantity, or amount included in the invoice data, and acquires the identified contract data. Then, it is determined whether or not the unit price or quantity included in the invoice data satisfies the transaction conditions indicated by the contract data. is displayed on the information terminal 2. By configuring the information processing device 1 in this manner, it is possible to determine whether or not there is an abnormality in the invoice data based on predetermined transaction conditions.

[Abnormality determination processing using a machine learning model]
Although the processing for determining abnormalities in unit prices or quantities included in invoice data on a rule basis has been described, the information processing apparatus 1 is configured to perform determination using a machine learning model trained using a known machine learning method. may be With this configuration, it is possible to present information for confirming the validity of the information included in the invoice data even when the judgment criteria cannot be clearly defined in advance.

The storage unit 12 is a trained model that has learned the product name and at least one of the unit price and quantity included in a plurality of past invoice data, and the product name and at least one of the unit price and quantity are input. Then, it stores a trained model for determining whether or not there is an abnormality in the input data. As an example, the storage unit 12 stores a trained model obtained by unsupervised learning of normal product names and unit prices or quantities included in past invoice data. In addition, if past invoice data containing the necessary amount of abnormalities for learning can be prepared in advance, a trained model that has learned teacher data with flags indicating normal or abnormal past invoice data may be stored. . The storage unit 12 may additionally learn the name of the business partner of the transaction partner included in the past invoice data as a feature amount. As an example, the storage unit 12 may store a plurality of trained models trained for each product name, or may store a plurality of trained models trained for each business partner name. .

Then, the display processing unit 133 inputs the product name and at least one of the unit price and quantity included in the invoice data to the learned model, and if it is determined that the input data is abnormal, the display processing unit 133 information is displayed on an external device. The display processing unit 133 acquires the learned model stored in the storage unit 12 . When the storage unit 12 stores a plurality of trained models trained for each product name or trading partner, the display processing unit 133 stores the product name included in the invoice data or the name of the destination company or issuer of the invoice data. Get the trained model corresponding to the business name. Then, the product name and at least one of the unit price and quantity included in the invoice data are input to the acquired learned model. If the determination result obtained from the learned model indicates that the bill data is abnormal, the display processing unit 133 causes the information terminal 2 to display the message shown in FIG.
