HENNGE One Now Supports “Bill One,” an Accounting DX Service

HENNGE K.K. (Headquarters: Shibuya-ku, Tokyo; Representative Director and CEO: Kazuhiro Ogura) announces that its cloud security service “HENNGE One,” which supports the safety and convenience of the working environment, now supports single sign-on to “Bill One,” an accounting DX service provided by Sansan, Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director, CEO, CPO: Chika Terada).

Due to recent legislation like the Invoice System and the Revised Electronic Book Preservation Act, corporate invoice processes are becoming increasingly intricate, placing a heavier burden on accounting departments. To alleviate the burden and enhance business efficiency while cutting costs, companies can consider adopting accounting DX solutions such as Bill One, which offers a valuable approach to digitizing invoice receipts and expense settlements.

The integration of HENNGE One and Bill One enables the companies employing HENNGE One to use a single sign-on to Bill One. They no longer have to manage complicated multiple IDs and passwords. Furthermore, HENNGE One’s access control features, such as IP Control and multi-factor authentication like device certificate, contribute to safer usage of Bill One, reducing the risks of unauthorized access.

HENNGE will continue to integrate more SaaS with HENNGE One to support companies’ convenient and secure adoption of SaaS.
