In the previous discussion, I conveyed that electronic contracts are legally valid and that there is a range of strictness in identity verification depending on the method of signature. This time, I will organize the differences between the "witness-type" and "party-type" that create this range along five axes. ---【Conclusion of this article】-------------------------------- - The witness-type involves the business entity, while the party-type involves the contracting parties themselves performing the electronic signature. - Both can be subject to the presumption of validity under the Electronic Signature Act if they meet the requirements. The difference manifests in the mechanisms of identity verification and the ease of demonstrating validity in case of disputes. - It is not about which is superior; rather, the basic principle is to differentiate based on the importance of the contract and the circumstances of the other party. -------------------------------------------------------- The full article can be accessed via the "Related Links."

Our representative, Koichi Yokoyama, a certified public accountant and tax accountant, will be speaking at the online seminar "Leading Successful AI Utilization: Learning About Reliable Data Foundations and Practical Know-How" on November 27 (Friday). ◆ Overview We will explain the important concepts of data in the AI era, reliable foundations, and how to utilize AI agents for business improvement. - Date and Time: November 27, 2026 (Friday) 13:00 - 15:05 - Venue: Online (Zoom) - Free - Application Deadline: November 25 (Wednesday) 17:00 - Organized by: Otsuka Shokai Co., Ltd. ◆ Seminar Presentation (14:05 - 14:35) "What Does It Mean to Create Reliable Data? - A Certified Public Accountant and Tax Accountant Explains How to Prepare Reliable Data Before Relying on AI" The quality and reliability of the data provided to AI agents directly influence the outcomes.

This time, I will explain the "another preservation deadline" hidden behind the numbers of the Electronic Bookkeeping Act and the "technical lifespan" unique to electronic contracts. ---Content of the article here-------------------------------- ■Differences in preservation periods for tax and legal purposes ■Contract cases that require long-term preservation of over 10 years 　●In the construction and building industry 　●In the manufacturing industry 　●In the case of ongoing long-term contracts ■Risks unique to electronic contracts: "Validity period of electronic signatures" ■Long-term preservation solutions (paperlogic) ■Summary: Building a long-term preservation system to protect corporate rights -------------------------------------------------------- The full text of the article can be accessed from the "Related Links."

We will explain the legal obligations of the "recipient" in electronic contracts that cannot be ignored, the risks of "leaving it unattended" from tax and legal perspectives, and provide a practical storage manual that can be used immediately. ---Content of the article here-------------------------------- [Part 1] ■ The biggest trap is thinking "it doesn't matter because our company hasn't implemented it." The obligation to store electronic records applies 100% to the recipient as well. ■ Is it legal to "leave it unattended" in the other party's system? Interpreting the latest views from the National Tax Agency. ■ The three major risks of "leaving it unattended" from the perspectives of legal affairs and internal controls. ■ What requirements must the recipient clear? [Part 2] ■ A review of the "two major requirements" of the electronic record law that the recipient must clear. ■ Reducing the burden on the field! A specific storage and operation manual for the "recipient." ■ The true solution is the integration and centralized management of "third-party system contracts." ■ Utilizing paperlogic for "ultimate automation and centralized management." ■ Even as the "receiving side," it is necessary to maintain control over electronic transactions! -------------------------------------------------------- The full text of the article can be accessed from the "related links."

The method of signing electronic contracts (party type and witness type) is directly linked to the strength of their legal effectiveness. In this article, we will outline the reasons why the more stringent "party type" has been difficult to popularize until now. ---【Conclusion of this article】-------------------------------- • There are two methods of signing electronic contracts: "witness type" and "party type," which differ in the strictness of identity verification. • The main reasons why the party type has not spread are the three factors of "effort, cost, and structural risks associated with entrusting the private key." • However, currently, with the spread of public personal authentication using My Number cards (JPKI), these three barriers are beginning to crumble. -------------------------------------------------------- The full text of the article can be accessed via the "Related Links."

In response to concerns about whether operations in the cloud and electronic contracts without seals have legal validity, this series will explain how to choose a signature method. As a premise, this time we will clarify the legal treatment of electronic contracts. (Note that the preservation rules under the Electronic Books Preservation Act are a separate topic.) ---【Conclusion of this article】-------------------------------- - Electronic contracts are validly established without a written document according to the principles of civil law. - The "paper" of a contract is not a requirement for the establishment of the contract, but rather a practical measure to retain evidence of the contract. - However, there are exceptions where certain contracts require a written document as mandated by law. -------------------------------------------------------- The full text of the article can be accessed via the "Related Links."

Is there no time in your daily operations to search for documents, wondering "Where is that document?" You might spend time looking for documents, asking others, or crossing departments... Such time can accumulate to a loss of 20 minutes a day, 1.7 hours a week, and 80 hours a year. The common belief that "storing on paper is the norm" is becoming a significant cost that hinders company growth. By digitizing paper documents (DX), we can create new time, make management decisions based on facts (data), and benefit from AI (artificial intelligence). Why not envision such a future with paperlogic?

This time, I will explain the differences in roles between the "accounting system" and the "document management system," which are surprisingly not well-known, as well as points that are often overlooked in legal compliance. ■ The difference between accounting systems and document management systems is their "scope of coverage." - Accounting System = Management of "money (numbers)" - Document Management System = Management of "evidence (documents)" ■ Documents often overlooked by accounting systems The accounting system primarily focuses on "accounting processing." - "Estimates" where no money movement occurs - "Delivery notes" and "purchase orders," which are intermediate points in transactions ⇒ There are cases where these are not stored or managed within the accounting system. This could be considered a deficiency under the Electronic Bookkeeping Preservation Act. ■ Supplementing the missing parts with an "independent system" While there are high-function ERP (Enterprise Resource Planning) systems that can manage everything from estimates to invoicing seamlessly, the reality is that the cost can be a significant barrier to implementation. Therefore, managing documents with an independent document management system like paperlogic is also an option. Paperlogic is currently offering a free trial. Please feel free to contact us.

Regarding the "quotation" used at the forefront of sales activities: "Do we really need to save everything when we revise it to Ver.1, Ver.2, etc., every time the amount or specifications change?" "Should we also keep the data from other companies that were not selected in competitive quotations?" Have you ever wondered about these questions? The Electronic Bookkeeping Act strictly demands the "authenticity" of data, but saving every process is a significant burden for the field. This time, we will clearly explain the boundaries of the preservation obligation in a case study format, incorporating the latest interpretations from the National Tax Agency's Q&A. *You can read the full text from the note in the "Related Links." [Contents of this article] 1. The boundary of the preservation obligation lies in "sending to external parties." - Items sent externally are "generally required to be preserved." - Items not sent externally have "no preservation obligation." 2. The sender's judgment: "Is it linked to a transaction?" 3. The recipient's judgment: "The perspective of the 'Corporate Tax Act' is important." ■ Note! "Version revisions" and "corrections/deletions" are different things. ■ A smart way to achieve reliable "version management." ■ Summary
