[Overview of invoice data management system S]
FIG. 1 is a diagram for explaining an outline of the invoice data management system S. The invoice data management system S is a system for managing the data described in the invoice, and includes an employee terminal 1, an invoice data management device 2, and an accounting terminal 3. The employee terminal 1, the invoice data management device 2, and the accounting terminal 3 are connected to a network such as a LAN (Local Area Network), and can transmit and receive data to and from each other.

The employee terminal 1 is a terminal used by an employee of a company that manages invoices using the invoice data management system S, and is, for example, a computer. Although only one employee terminal 1 is shown in FIG. 1, a plurality of employee terminals 1 may be included in the invoice data management system S via a network.

The employee terminal 1 transmits invoice image data (hereinafter referred to as “invoice image data”) issued by another company to the invoice data management device 2 by using an electronic message. The invoice image data is data in which the content of the invoice is converted into an image, and is included in an electronic file in a file format such as pdf, JPEG, or bmp. The invoice image data is transmitted from the employee terminal 1 to the invoice data management device 2 in association with the electronic message.

The electronic message is a message including text data, such as an e-mail, a chat message, and an SNS (Social Networking Services) message. If the e-mail is an e-mail, the invoice image data is included as an e-mail attachment. When the electronic message is a chat message or an SNS message, the bill image data is stored in the storage area of the computer corresponding to the address (for example, the link destination) indicated by the text data contained in these messages, and the billing is performed. The document data management device 2 may receive invoice image data via the computer. In the following description, the case where the electronic message is an electronic mail will be described as an example, but the same effect can be obtained when the electronic message is an electronic mail.

The employee terminal 1 attaches invoice image data received by e-mail from, for example, an e-mail to an e-mail according to an operation of an employee using the employee terminal 1, and the invoice data management device 2 causes the invoice data management device 2. Send the e-mail to the specified e-mail address that can be received. The employee terminal 1 may send an invoice image data created by a scanner or a camera that has read a paper invoice by attaching it to an e-mail.

FIG. 2 is a diagram showing an example of an invoice transmitted by the employee terminal 1 to the invoice data management device 2. The invoice shown in FIG. 2 contains the name, address, and contact information of the business operator that issued the invoice (hereinafter referred to as "issuing business operator"). In addition, the name of the product to be billed, the number of products purchased, the amount of the purchased product, the tax amount, etc. are described.

Upon receiving the invoice image data, the invoice data management device 2 identifies a character string included in the invoice image data (hereinafter, referred to as "first character string"). The invoice data management device 2 specifies, for example, a character string such as the name of the invoice issuing business operator, the name of the product to be billed, the number of purchased items, the amount of money, and the tax amount. Further, the invoice data management device 2 specifies a character string (hereinafter, referred to as "second character string") included in the e-mail received with the invoice image data attached. The invoice data management device 2 specifies, for example, a character string such as the name of the employee who sent the invoice image data by e-mail and the name of the department to which the invoice is assigned.

The invoice data management device 2 registers the first character string and the second character string corresponding to the same e-mail in the invoice database as one data group. The invoice data management device 2 transmits the data registered in the invoice database to the accounting terminal 3 in response to the request from the accounting terminal 3.

The accounting terminal 3 is a terminal used by an employee (for example, an accounting person) who processes an invoice, and is, for example, a computer. The accounting terminal 3 transmits a request for accessing the invoice database stored in the invoice data management device 2 to the invoice data management device 2 and is registered in the invoice database, for example, in response to an operation by an accounting person. The collected data is acquired from the invoice data management device 2 and displayed.

As described above, the invoice data management device 2 is registered in the invoice data management device 2 in a state in which the first character string and the second character string necessary for processing by the accounting staff are integrated into one data group. Therefore, when the accounting terminal 3 acquires the data registered in the invoice database, the accounting staff can use various information contained in the invoice and various information necessary for managing the invoice (various information necessary for managing the invoice). For example, the accounting process can be executed quickly without inputting the applicant's name).
Hereinafter, the configuration and operation of the employee terminal 1 and the invoice data management device 2 will be described in detail.

[Functional configuration of employee terminal 1]
FIG. 3 is a diagram showing a functional configuration of the employee terminal 1. The employee terminal 1 has a communication unit 11, an operation unit 12, a storage unit 13, and a control unit 14. The control unit 14 has an invoice acquisition unit 141, a mail creation unit 142, and a mail transmission / reception unit 143.

The communication unit 11 is a communication interface for transmitting an e-mail to the invoice data management device 2 via the network. The communication unit 11 has, for example, a communication controller for transmitting and receiving e-mail. For example, the communication unit 11 inputs an e-mail received from the computer of the company that issued the invoice via the Internet to the mail transmission / reception unit 143, or inputs an e-mail from the mail transmission / reception unit 143 via the intranet. It may be sent to the invoice data management device 2.

The operation unit 12 has a device such as a keyboard, a mouse, and a display for the user of the employee terminal 1 to perform an operation for inputting an e-mail text. The operation unit 12 notifies the mail creation unit 142 of the data input by the user's operation.

The storage unit 13 has a storage medium such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a hard disk. The storage unit 13 stores a program executed by the control unit 14. Further, the storage unit 13 temporarily stores the invoice image data.

The control unit 14 is, for example, a CPU (Central Processing Unit). The control unit 14 functions as an invoice acquisition unit 141, a mail creation unit 142, and a mail transmission / reception unit 143 by executing a program stored in the storage unit 13.

The invoice acquisition unit 141 acquires invoice image data. The invoice acquisition unit 141 acquires, for example, the invoice image data attached to the e-mail received via the communication unit 11 and the mail transmission / reception unit 143. The invoice acquisition unit 141 may directly acquire the invoice image data from the mail transmission / reception unit 143, or the invoice image data stored in the storage unit 13 by the mail transmission / reception unit 143 may be acquired. The mail transmission / reception unit 143 may acquire invoice image data created by reading a paper invoice by an image reading device such as a scanner or a digital camera. The invoice acquisition unit 141 inputs a file containing the acquired invoice image data as an attached file to the mail creation unit 142 in response to an operation of a user who creates an e-mail using, for example, the employee terminal 1.

The mail creation unit 142 creates an e-mail to be sent to a predetermined e-mail address corresponding to the invoice data management device 2. Specifically, the mail creation unit 142 creates an e-mail including a character string input by the user of the employee terminal 1 using the operation unit 12, and inputs the created e-mail to the mail transmission / reception unit 143. The mail creation unit 142 inputs a file containing the invoice image data input from the invoice acquisition unit 141 according to the user's operation to the mail transmission / reception unit 143 as an attachment file of the e-mail to be created.

The mail transmission / reception unit 143 attaches a file containing the invoice image data received from the external device to the e-mail created by the mail creation unit 142, and sends the e-mail to a predetermined e-mail address. The external device is the computer of the business operator that issued the invoice, or the reading device that reads the invoice.

FIG. 4 is a diagram showing an example of an e-mail transmitted by the mail transmission / reception unit 143. The e-mail area R11 shown in FIG. 4 includes a transmission date / time, a sender, a destination, and a subject. The sender column contains the e-mail address of the user of the employee terminal 1. The address field contains an e-mail address corresponding to the invoice data management device 2. The subject field is an example of a second character string input by the user of the employee terminal 1, and the invoice data management device 2 is an e-mail for specifying the first character string included in the invoice image data. Contains a predetermined character string indicating that.

The e-mail area R12 shown in FIG. 4 contains an attached file. In this example, a file with the file name "Invoice S1000224" is attached. The file name is also an example of the second character string.

The area R13 of the e-mail shown in FIG. 4 includes the body of the e-mail. As an example, the body of the email includes the name of the applicant's department, the employee code, and the name of the employee. The employee code is a symbol or character string for identifying an employee. These character strings included in the body of the email are also examples of the second character string. In order for the invoice data management device 2 to easily identify the predetermined second character string, it is desirable that the predetermined character string is described in the mail body in a predetermined format. The area R13 may not include a character string, and may include only one of the employee code and the employee's name.

[Functional configuration of invoice data management device 2]
FIG. 5 is a diagram showing a functional configuration of the invoice data management device 2. The invoice data management device 2 has a communication unit 21, a storage unit 22, and a control unit 23. The control unit 23 includes an image data acquisition unit 231, a first character string specifying unit 232, a second character string specifying unit 233, and a data registration unit 234.

The communication unit 21 includes a communication controller for receiving e-mail from the employee terminal 1 via the network and transmitting the data stored in the storage unit 22 to the accounting terminal 3. The communication unit 21 inputs a file attached to the e-mail received from the employee terminal 1 to the image data acquisition unit 231. Further, the communication unit inputs the e-mail received from the employee terminal 1 into the second character string specifying unit 233. Further, the communication unit 21 transmits the data input from the data registration unit 234 to the accounting terminal 3.

The storage unit 22 includes a storage medium such as a ROM, RAM, and a hard disk. The storage unit 22 stores a program executed by the control unit 23. Further, the storage unit 22 stores an invoice database registered in a state in which the first character string and the second character string included in the invoice image data transmitted by the employee terminal 1 and the e-mail are associated with each other. .. Further, the storage unit 22 stores one or more third character strings in association with one or more second character strings. As an example, the storage unit 22 stores an employee database in which the name of the employee as the second character string and the name of the department to which the employee belongs as the third character string are associated with each other.

The image data acquisition unit 231 acquires invoice image data using e-mail. Specifically, the image data acquisition unit 231 acquires the invoice image data included in the file attached to the e-mail received from the employee terminal 1 by the communication unit 21. The image data acquisition unit 231 inputs the acquired invoice image data to the first character string specifying unit 232.

The first character string specifying unit 232 identifies a plurality of first character strings included in the invoice image data input from the image data acquisition unit 231. The first character string specifying unit 232 identifies the first character string included in the invoice based on the invoice image data, for example, by executing OCR processing. The first character string specified by the first character string specifying unit 232 is, for example, the name of the issuing company, the invoice issuance date, the name of the product to be billed, the number of products purchased, the amount of the purchased product, and the amount of the purchased product. It is a tax amount, etc., and is a character string corresponding to the information registered in the invoice information database.

The first character string specifying unit 232 includes, for example, an AI engine (artificial intelligence engine), and for example, a machine learning model constructed by deep learning the relationship between image data and a character string as teacher data is used. Specifies the character string with high accuracy. The first character string specifying unit 232 inputs a plurality of specified first character strings to the data registration unit 234. The first character string specifying unit 232 inputs a plurality of first character strings to the data registration unit 234 in association with, for example, the file name of the invoice image data.

The second character string specifying unit 233 identifies one or more second character strings other than the invoice image data included in the e-mail received from the employee terminal 1 by the communication unit 21. The one or more second character strings other than the invoice image data are at least one of the character strings included in the e-mail area R11 and the area R13 shown in FIG. 4, and the file name of the attached file. .. That is, the second character string specifying unit 233 specifies one or more second character strings included in the subject information or the sender information of the e-mail.

As an example, in the second character string specifying unit 233, for example, among the character strings included in the area R13, the character string described next to the character string "applicant" is assumed to be the name of the department to which the applicant belongs. Identify, identify the string listed below as the employee code, and identify the string listed next as the employee's name. The second character string specifying unit 233 notifies the data registration unit 234 of the specified second character string.

The data registration unit 234 acquires a plurality of first character strings from the first character string specifying unit 232, and acquires one or more second character strings from the second character string specifying unit 233. The data registration unit 234 is a second character in an e-mail in which one or more first character strings among a plurality of first character strings and invoice image data including the one or more first character strings are transmitted. The invoice data is registered in the invoice database registered in association with one or more third character strings corresponding to one or more second character strings specified by the column identification unit 233.

The third character string is the same character string as the second character string, or a character string different from the second character string stored in the storage unit 22 in association with the second character string in advance. That is, the data registration unit 234 registers in the invoice database one or more third character strings associated with the one or more second character strings specified by the second character string identification unit 233 in the storage unit 22. The data registration unit 234 may register the second character string included in the e-mail as the third character string in the invoice database, and can be acquired via the storage unit 22 without using a communication means. A third character string different from the two character strings may be registered in the invoice database.

When the second character string is the employee's name, the data registration unit 234 sets the employee code as the third character string, for example, by referring to the employee database in which the employee's name and the employee code are associated with each other. Register in the invoice database as one of. If the second string is an email address, the data registration unit 234 refers to the employee database associated with the email address and at least one of the employee's name, employee code or department name. , At least one of the employee's name, employee code or department name may be registered in the invoice database as a third character string.

The second character in the e-mail to which the data registration unit 234 has transmitted the plurality of first character strings specified by the first character string identification unit 232 and the invoice image data including the plurality of first character strings. The method of associating with one or more second character strings specified by the column specifying unit 233 is arbitrary. In the data registration unit 234, for example, a second character string that matches one first character string included in a plurality of first character strings newly input from the first character string identification unit 232 is specified as a second character string. The plurality of first character strings are associated with one or more second character strings, provided that they are included in one or more second character strings newly input from unit 233.

The data registration unit 234 uses the file name of the file containing the invoice image data attached to the e-mail to input a plurality of first character strings and one or more second character strings corresponding to the same e-mail. It may be associated. Specifically, the data registration unit 234 is associated with the plurality of first character strings and the file name input from the first character string specifying unit 232 (that is, the invoice image data in which the plurality of first character strings are specified). One or more second character strings notified from the second character string specifying unit 233 in association with the same file name as the file name of the image file including) are associated with the plurality of first character strings. When the data registration unit 234 uses the file name of the attached file, the accuracy of associating the first character string with the second character string is improved.

FIG. 6 is a diagram showing an example of a screen on which data to be registered in the invoice database by the data registration unit 234 is displayed. The screen is, for example, a screen displayed on the accounting terminal 3.

Area R21 contains an invoice summary and an applicant summary. The "slip number" is an invoice number which is one of the first character strings included in the invoice image data, and is an attached file name included as a second character string in the e-mail.

The "payee" in the area R21 corresponds to the first character string of the issuer name of the invoice included in the invoice image data. The "application date" corresponds to the second character string indicating the transmission date and time included in the e-mail area R11 shown in FIG. The "applicant" corresponds to the second character string indicating the name of the employee included in the e-mail area R13 shown in FIG. The "affiliation department" corresponds to the second character string indicating the name of the employee's affiliation department included in the e-mail area R13 shown in FIG.

The area R22 of FIG. 6 includes a plurality of first character strings included in the invoice image data. Area R23 contains information for obtaining approval to process the invoice. The "applicant" column contains the name of the employee that was included in the email area R13. The "Approver" column contains the name of the approver for processing the invoice filed by the employee. The data registration unit 234 identifies the name of the boss registered as the approver of the employee who is the applicant as the third character string indicating the approver, for example, by referring to the employee database.

Even if the data registration unit 234 checks the consistency between the first character string and the second character string or the third character string before registering the first character string and the second character string in the invoice database. good. In the data registration unit 234, for example, at least one of a plurality of first character strings and at least one of one or more second character strings or at least one of one or more third character strings are one. If so, a process different from the case where at least one of the plurality of first character strings and at least one of one or more second character strings or one or more third character strings do not match is executed. do.

Specifically, when it is determined that the data registration unit 234 matches, the data registration unit 234 associates the first character string with the third character string and registers them in the invoice database. On the other hand, when the data registration unit 234 determines that they do not match, the first character string and the third character string are not associated with each other and registered in the invoice database, and the sender of the e-mail is inadequate. You may send an email notifying you that there is.

The data registration unit 234 has at least one of a plurality of first character strings and at least one of one or more second character strings, such as an invoice number and a file name reflected in the "slip number". The first character string and the second character string are associated and registered in the invoice database on condition that they match. That is, the data registration unit 234 is one with one or more first character strings, provided that at least one of the plurality of first character strings matches the name of the attached file containing the invoice image data. The above third character string may be registered in the invoice database.

By checking the consistency in this way, the data registration unit 234 can definitely register the first character string and the third character string corresponding to the same invoice in the invoice database. Further, by using the invoice number as the file name attached to the e-mail transmitted by the employee terminal 1, the data registration unit 234 selects the first character string and the second character string corresponding to the same invoice. Definitely easier to associate and register in the invoice database. The file name used for the consistency check is not limited to the invoice number, and may include the name of the business operator that issued the invoice and the invoice issuance date.

At the bottom of the screen shown in FIG. 6, an operation button for sending an approval request to the approver is included. When the person in charge of accounting using the accounting terminal 3 clicks the button, the invoice data is transmitted to the approver. When the approval by the approver is completed, for example, the accounting staff can perform an operation to execute the remittance process, and when the remittance process operation is performed, the process of remittance of the amount shown in the invoice data is executed. The invoice data is sent to an external server and the remittance process is executed.

The data registration unit 234 has one or more first character strings and one or more third character strings corresponding to a plurality of predetermined items to be registered in the invoice database before sending the approval request to the approver. It may be determined whether or not it is present. The data registration unit 234 has a case where one or more first character strings and one or more third character strings corresponding to a plurality of predetermined items to be registered in the invoice database are prepared, and a predetermined case to be registered in the accounting database. The processing is changed depending on whether at least a part of the one or more first character strings and the one or more third character strings corresponding to the plurality of items of is not aligned.

The data registration unit 234 is, for example, one or more, provided that one or more first character strings and one or more third character strings corresponding to a plurality of predetermined items to be registered in the invoice database are prepared. The approval process for executing the remittance process of the billing amount included in the first character string is executed. Specifically, when the first character string and the third character string corresponding to all the items shown in FIG. 6 are acquired from the first character string specifying unit 232 or the second character string specifying unit 233, the data registration unit 234 causes the accounting terminal 3 to display the "send to approver" button. On the other hand, when any of the first character strings and the third character strings corresponding to the items shown in FIG. 6 cannot be obtained from the first character string specifying unit 232 or the second character string specifying unit 233. In addition, the data registration unit 234 sends an e-mail notifying the sender of the e-mail that there is a defect.

[Operation flow of invoice data management device 2]
FIG. 7 is a flowchart showing the operation flow of the invoice data management device 2. The flowchart shown in FIG. 7 starts from the time when the employee terminal 1 sends an e-mail with the invoice image data as an attached file.

First, the image data acquisition unit 231 receives the e-mail transmitted by the employee terminal 1 (S11). The first character string specifying unit 232 identifies a plurality of first character strings included in the invoice image data attached to the e-mail (S12). Further, the second character string specifying unit 233 specifies one or more second character strings included in the e-mail (S13). The data registration unit 234 specifies a third character string corresponding to the second character string (S14). The timing at which the first character string specifying unit 232 executes the processing of S12 and the order in which the second character string specifying unit 233 executes the processing of S13 are arbitrary.

Subsequently, the data registration unit 234 determines whether or not there is a problem as a character string to be registered in the invoice database based on at least one of the specified first character string, second character string, or third character string. (S15). The data registration unit 234 determines, for example, whether there is a problem in the consistency between the first character string and the second character string or the third character string as described above, or all items to be registered in the invoice database. It is determined whether or not the first character string and the third character string corresponding to are aligned.

When the data registration unit 234 determines that there is no problem (YES in S15), the data registration unit 234 registers the first character string and the third character string in the invoice database (S16). If the data registration unit 234 determines that there is no problem, the data registration unit 234 notifies the approver of the approval request in response to the operation for transmitting the data to the approver (S17). When the approval process is completed (S18), the data registration unit 234 enables the process to be executed in order to remit the billed amount (S19).
