The recognition that "the PDF invoice received from the other party must be stored as electronic data" is widely accepted. However, is that response truly sufficient for perfection? ◆ The "receipt" of electronic transactions includes issuance and delivery The Electronic Bookkeeping Act defines "electronic transactions" as the receipt of electromagnetic records related to transaction information. Breaking down the term "receipt" is key to understanding. - "Receipt": Receiving electronic data such as invoices and receipts from business partners - "Issuance": Issuing and delivering electronic data such as invoices and estimates to business partners When downloading a PDF from your company's accounting system and attaching it to an email, or concluding electronic contracts through a cloud-based invoicing service, both the receiving party and the issuing party (your company) are obligated to store the data. 【Utilizing paperlogic DESKTOP for document management】 - Elimination of manual input - Assurance of reliable searchability - Centralized management of receipt and issuance → paperlogic DESKTOP addresses the challenges of complex metadata management in the storage of these issued documents.

We are pleased to announce that Arsystem Co., Ltd. has received the "Health Management Excellent Corporation 2025" and "Next Bright 1000*" certifications under the Health Management Excellent Corporation Certification System promoted by the Ministry of Economy, Trade and Industry and the Japan Health Conference. *Certified corporations that applied for Bright 500, ranking from 501 to 1500. This year, we are also able to receive the new certification "Next Bright 1000," and we feel happy to have taken another step toward realizing our vision of being "the company that values its employees the most on Earth." Moving forward, we will continue to strive to create a "Love Al" environment where each of our valued employees can work healthily and energetically, both physically and mentally.
