Achieving Efficient Business! Points for Introducing a System for Receiving Invoices
In today's world, where external factors such as a shrinking workforce are forcing businesses to become more efficient, companies are constantly having to understand and utilize new technologies and systems. In this context, invoice receipt systems are now attracting attention as playing an important role. By reducing manual labor and errors, this system saves time and money and is key to keeping the entire business process running smoothly. This article explores the effective use of invoice receipt systems and how they can contribute to efficient business operations.

What is an invoice receipt service?
Invoice receipt services are designed to digitize invoices and streamline a series of tasks. The services offered vary in size, but include the ability to automate the processing of received invoices and to link with other systems to generate data for accounting journal entries and transfers.
By utilizing this service, it is possible to significantly reduce the workload from receiving invoices to subsequent processing, which used to be complicated. In addition, it is important to understand the correct way to store invoices to meet legal requirements and points to consider when sending receipt emails.
Problems when receiving invoices
Depending on the client, invoices are provided in different formats, such as paper or PDF, and there is a wide variety of ways to receive invoices, such as by mail, fax, or e-mail. It is very time-consuming to deal with invoices in different formats each time, and to check and input data. Especially during the Corona disaster, we often found ourselves in situations where we had to come into the office just to receive an invoice, even though we were working from home.
A wide variety of receipt methods complicate the process.
A major challenge is the variety of ways to receive invoices, which differ for each supplier. Invoices are usually passed on to purchasing or accounting personnel, who receive them in a variety of ways, including by mail, e-mail, website download, or even by delivery of a written notice of payment at the end of each month (so-called "invoice-less transactions").
Variations in these receipt methods can hinder the smooth processing of payments from purchasing or accounting personnel to the next step in the process.

Complicated process of obtaining approval in accounting
The first step in processing invoices in accounting to obtain approval for payment is to circulate them to the relevant departments. Once received, a number of complex steps must be taken, such as checking the description and recording the transaction by the accountant.
Because invoices do not always come in a certain format, some experience and skill are required to complete these processes quickly and accurately.
Ambiguity in response process
Because there are many steps in the invoice process, it is not always easy to know when an invoice is received and when it is reviewed by the accountant.
Because it is unclear who is currently processing a particular invoice, it is difficult to quickly ascertain the current status without a system when a problem arises.
Barriers to flexible work styles
In the wake of the new coronavirus, many companies have been strengthening remote work and telecommuting. However, if you receive paper invoices in the mail, you will need to come into the office to process them.
The method of receiving invoices is often an obstacle to achieving flexible work styles.
Increased workload due to introduction of invoice system
An invoice system will be introduced in Japan on October 1, 2023. This new system will add new mandatory items to invoices and make it mandatory to issue and keep proper invoices. The accounting department will need to adapt to the new tasks, as the new system requires a different method of creation and storage than the old invoices. This is expected to increase the workload of the accounting department.
In addition, the invoice system will be enforced from October 1, 2023, requiring registration as a qualified invoicing business and compliance.
Transitional measures for tax credits on purchases for transactions with tax-exempt businesses are applicable until September 30, 2026, but after that date, tax credits will not be allowed at all, so it is necessary to take action as soon as possible. Therefore, it is necessary to take action as soon as possible.
Advantages of introducing an invoice receipt service
Here are four advantages of introducing an invoice receipt service.
(1) Reduce workload by digitizing invoices
One of the key features of the invoice receipt service is the automation of invoice data. This feature allows for the smooth capture of company names and invoice amounts without the need to look at the originals and manually enter them into accounting software or workflow systems. This allows for rapid data processing and eliminates the worry of input errors. The result is faster invoice payment and smoother transactions with business partners.
2) Payment details simplifying internal application and approval process
Many invoice receipt services have the ability to provide a submission and approval process for managing payment requests. Some services can even automatically set up the appropriate approval process based on departmental information and payment amounts. Thus, multi-step approvals, such as payment requests from other departments to the accounting department, can be smoothly submitted and approved in the cloud.
Furthermore, each invoice can be checked in real time to see "who applied and approved it, when, and who is waiting for approval in the future," which can significantly reduce the time and effort required for internal application procedures.

(iii) Quick response to updates in legal systems
The legal system for processing invoices has been undergoing significant changes in recent years against the backdrop of ongoing digitization and changes in the business environment. 2022 will see the revision of the Electronic Bookkeeping Law, which will revise the requirements for electronic storage of invoices, and the invoice system will come into effect on October 1, 2023, requiring the registration of qualified invoicing businesses In addition, the electronic storage requirement for invoices will be revised in accordance with the revision of the Electronic Bookkeeping Act in 2026.
In addition, a transitional measure for the deduction of taxes on purchases for transactions with tax-exempt businesses is in effect until September 30, 2026, but after that date, the deduction of taxes on purchases will be completely prohibited, so early action is required.
Latest Trends in Electronic Bookkeeping Law
In 2022, the Electronic Bookkeeping Law will be revised, and electronic data storage will be required. Companies will need to introduce electronic invoicing to comply with this.
From January 1, 2024, data storage of electronic transactions will become fully mandatory, and paper storage will no longer be allowed. Currently, it is recommended to use a cloud-based invoice management system that complies with the requirements of the Electronic Bookkeeping Law.
From 2023, an invoice system was introduced that requires the preservation of "qualified invoices".
While it is possible to comply with these legal requirements in-house, it can require a great deal of man-hours. This is where a cloud-based invoice receipt service comes in handy, which is updated as new laws and regulations come into effect. It is quite possible that new legislation will emerge in the future. The ability to constantly adapt to invoice-related laws and regulations is one of the benefits of using an invoice receipt service. The ability to integrate with various services, including the
(4) Integration with other services to generate transaction data and remittance information
API, to generate journal entries and transfer data is another advantage of implementing an invoice receipt service.
Generation of accounting data
After receiving invoices from suppliers and completing payment, the information needs to be recorded in the accounting software. If there are many invoices, it is easy for input errors and omissions to occur.
Therefore, an invoice receipt service can be linked to other services via CSV or API to automatically import invoice and transfer information into the accounting software and streamline the creation of journal entries.
Generate Remittance Information
By linking with other services, the Invoice Receipt Service can automatically generate bank transfer data that is compatible with the JBA format, greatly improving the efficiency of bank transfer operations.

Types of invoice receipt services and how to choose one
Invoicing services are basically classified into three different types, depending on who enters the invoice data.
Each type is described in detail below.
(1) Service vendor receives and digitizes invoices on behalf of the client
In the first method, the customer requests a traditional invoice, but the service provider receives and scans the invoice on their behalf. For example, for paper invoices, the service provider receives and scans them on behalf of the company, and is even responsible for digitizing them.
The process after receiving the invoice varies from service to service. Some, such as HUE Digital Invoice, Bill One, and TOKIUM Invoice, store the invoices in a warehouse and destroy them after a certain period of time.
(2) Service vendor supports in-house data conversion process
While invoices will still be processed in-house, AI OCR will help reduce the workload. Specifically, paper invoices can be scanned, and PDF invoices attached via email can be uploaded directly to the system, and AI OCR will automatically convert each item into data, greatly reducing the need for manual input.
The highly accurate AI OCR feature is especially useful when a large number of paper invoices are sent in a fixed format each month.

(3) Invoices registered by client companies
The third option is to have suppliers enter invoice information directly into the invoice receipt system. This is not easy to implement because it requires cooperation, but if the partner company uses a similar service or is receptive to the proposal, a significant improvement in operational efficiency can be expected. This is especially effective when the number of partner companies is limited and a relationship of trust has been established.
It is also important to ensure that separately received invoices can be manually uploaded into the system and centralized with other data to prevent accidental double-checking.
Six points to consider when choosing an invoice receipt service
Most invoice receipt services do not differ significantly in their basic functionality. They automatically convert the information on received invoices into data that can be viewed and retrieved in the system. All services are compliant with the revised Electronic Bookkeeping Law. When preparing point-of-sale invoices, it is important to follow the guidelines for creating polite and timely mailings.
So how should you choose the right service for your company? Here are six important points of comparison that are essential to choosing the right service.
(1) Whether to receive and digitize invoices in-house or to do it on behalf of the client company
The extent to which you want to reduce the effort of invoice processing, i.e., whether to receive and digitize invoices in-house or outsource the process, is a very important decision.
As already mentioned, there are two types of invoice receipt services: "system stand-alone" and "system + outsourced". The "system stand-alone" type is suitable for companies that want to streamline only the data processing of invoices, while the "system plus agent" type is suitable for companies that want to improve overall efficiency, including operations outside the system such as receipt, confirmation, and storage of the original invoices.
Two criteria for selection should be considered: (1) the number of invoices to be received each month and (2) the format of those invoices.
(2) Whether digital storage of tax-related documents other than invoices is possible?
If you are able to comply with the Electronic Bookkeeping Act for invoices, but have not caught up with the Act for documents related to national taxes, such as receipts, estimates, and delivery slips, you will need to introduce another system, which will increase your management costs. Unless you are already using a voucher management system, it is important to ensure that the system can handle documents related to national taxes other than invoices, as well as the DENCHO Law.
(iii) Accuracy of data conversion and processing time
Each service differs in the accuracy and time required to convert invoice information into data. The "system stand-alone type" uses AI-OCR for automatic data conversion, and while there is a risk of error, the processing time is short. On the other hand, the "system + agent type" is performed by an operator, and while the accuracy is very high, it may take more time than the stand-alone type. Since there is a trade-off between accuracy and time, it is a good idea to determine your company's priorities before choosing a service.
The accuracy of AI-OCR is affected by the format of the invoice. For standard invoices, AI-OCR can be expected to be highly accurate, but for invoices in a wide variety of formats, errors may increase and corrections may be necessary.
Conversely, an operator-based system guarantees high accuracy for any invoice format. However, running costs tend to be higher, but the advantage is that it eliminates the need for in-house verification.
(iv) Whether a full support system is in place
No matter how excellent a system may be, it is meaningless if it is not easy to use. When considering the introduction of a system, it is important to confirm that it has a solid support system. In particular, it is necessary to check whether "support for initial setup" and "operational support after implementation" are properly provided.
Invoicing services go beyond mere data conversion to include functions that digitize internal application and approval processes, as well as functions that allow journal data to be set up in line with the accounting system. In order to take full advantage of these features, it is key to have support to help with the initial setup at the time of implementation.
In addition, you should make sure that there is a point of contact for email, chat, or phone calls should any problems arise after implementation. Some services may take a long time to respond, and in some cases there may be a limit to the number of responses, so it is a good idea to confirm these points in advance.

(5) Whether smooth integration with accounting system is possible?
When linking billing data to an accounting system, there are two methods: using an API or importing a CSV file. Which method you choose may depend on the service you use.
The advantage of using an API is that data can be automatically linked between systems without manual manipulation of the data by the accounting staff. However, API linkage is often only applicable to specific accounting systems.
The method of importing CSV files allows linkage with most accounting systems, but some services may require manual data formatting. We recommend choosing a service that does not require manual formatting to avoid delays in closing.
⑥ Are there other areas where labor savings can be made in addition to receipt and data conversion
Some services may incorporate additional agency functions in addition to the basic functionality, such as
