Our strengths

  1. Adopted by many large enterprises

    The AI we provide is specialized in the field of accounting. Furthermore, we have realized more efficient expense reimbursement operations by refining the performance of our AI and our solutions and through deepening our understanding of accounting operations. As a result, our solutions are being adopted by an increasing number of large enterprises.

  2. No. 1 share in sales of payment-related document solutions

    According to the survey conducted MM Research Institute, Ltd. (AI-OCR Market Trend Survey in the Field of Accounting DX (2022 Edition)), we achieved No. 1 share in the sales of payment-related document solutions in Japan in FY2021*.

  3. Centralized management of paper, PDF and digital invoices

    Peppol is a set of digital invoice specifications, and its Japanese version is currently being developed under the leadership of the Digital Agency. We are a Peppol service provider accredited by the Digital Agency. Our solutions make it possible to handle not only traditional paper invoices and PDF invoices, but also digital invoices with the same product to realize both “analog to digital” and “digital to digital” transformation.

  4. Functions complying with the latest Japanese laws

    Under the “Invoice System” scheduled to start in October 2023, the recipient of an invoice needs to confirm the registration number. We have started providing convenient functions to help confirm the registration number and functions for checking the calculation of tax and other amounts by tax rate category.

    In addition, we plan to provide functions that satisfy the preservation and search requirements of the amended “Law Concerning Preservation of National Tax Records in Electronic Form” going forward as they become available for release.

The future of accounting

Accounting and finance departments are currently spending enormous effort for data input to ERP and related confirmation and approval work. By automating these tasks, we will create an environment in which our clients can focus on strategic accounting and preparing reporting materials.
