Electronic Contract Service "GMO Sign" and "Administrative Management Support Service FAST Financial Accounting" Collaborate [GMO GlobalSign Holdings]

GMO GlobalSign Holdings K.K. (Headquarters: Shibuya-ku, Tokyo, Representative Director and President: Mitsuru Aoyama, hereinafter GMO GlobalSign HD)'s electronic contract service for local governments, "GMO Sign Gyokaku DX Electronic Contract" (hereinafter GMO Sign), and Japan System Co., Ltd. (Headquarters: Shibuya-ku, Tokyo, Representative Executive Officer and President: Katsuya Matsuno, hereinafter Japan System)'s "Administrative Management Support Service FAST Financial Accounting" (hereinafter FAST Financial Accounting) have commenced cooperation today, May 13, 2026 (Wednesday).

Through this cooperation, contract decision information (contract counterparty, contract details, contract amount, decision reason, etc.) managed in "FAST Financial Accounting" can now be automatically linked to "GMO Sign", digitalizing the entire process from contract conclusion to management. By unifying information management between "FAST Financial Accounting" and "GMO Sign", the effort for duplicate input is reduced, alleviating the workload for local government operations and preventing input errors.

[Background and Overview of Cooperation]

"GMO Sign" is a cloud-based electronic contract service that provides one-stop solutions from contract conclusion to management. On the other hand, "FAST Financial Accounting" is a solution that strengthens the PDCA cycle (planning/budgeting, execution, settlement, evaluation) in administrative and fiscal management, contributing to the promotion of local government DX.

Since the establishment of the "Digital Agency" in the autumn of 2021, the digitalization of administration has been promoted in local governments nationwide. As of 2026, government agencies and local governments are actively utilizing digital technologies. Recently, electronic contract services that digitalize contract conclusion operations and financial accounting systems that centrally manage contract decision information for transactions between government agencies and companies have been adopted by many local governments. However, if electronic contract services and financial accounting systems are introduced separately, without system integration, issues such as increased workload for staff due to duplicate management of contract information and increased man-hours arise.

To solve such problems, GMO GlobalSign HD and Japan System have started cooperating with "GMO Sign" and "FAST Financial Accounting" with the aim of improving convenience. By linking various contract decision information managed in "FAST Financial Accounting" to "GMO Sign", it can be utilized seamlessly, enabling efficiency and speed in contract procedures, and preventing manual input errors and duplicate management. Furthermore, unified management of contract information makes it easier to search and share information, improving operational transparency and accuracy. As a result, it contributes to shortening the lead time until contract conclusion and strengthening compliance.

[Precedent Case]

In Kariya City, Aichi Prefecture, "GMO Sign" has been linked with "FAST Financial Accounting" and in use since January 2026, already leading to a reduction in human errors and an improvement in operational efficiency.

[Comment from Kariya City, Contract and Inspection Division]

Kariya City has been using "FAST Financial Accounting" since 2009. When introducing "GMO Sign" in January 2026, cooperation with "FAST Financial Accounting" commenced, and it has been in operation as a precedent.

The effect obtained from the cooperation between "FAST Financial Accounting" and "GMO Sign" is that information held by "FAST Financial Accounting" can be automatically linked to "GMO Sign", eliminating the need for manual input of contract numbers and case names, thereby preventing human errors. We feel that administrative efficiency has been improved by linking the two services.

Currently, the main use is for cases related to construction work, etc., where the Contract and Inspection Division and Waterworks Division conclude contracts, but in the future, we plan to expand the departments and scope of contracts using it.

Based on Kariya City's success story, GMO GlobalSign HD and Japan System aim to horizontally deploy the cooperation of both services to local governments nationwide, further strengthen functions, and contribute to the promotion of DX in local governments nationwide.
