About "インフォマート"
What is Infomart
Infomart is the "BtoB Platform" series from Infomart Corporation (TSE Prime, securities code 2492) that lets companies exchange invoices, orders, contracts and other B2B documents as data, completing them on screen. Accounting and purchasing staff spend less time printing, mailing, keying in and filing paper, PDF and fax documents; the platform is used by more than 1.3M companies, with over ¥71 trillion in annual transaction value (official announcement, October 2026). Trading partners (the receiving side) use it for free; the adopting company pays a setup fee plus a monthly fee — the flagship "BtoB Platform Invoice" is quote-only (amounts not disclosed), while "BtoB Platform Contracts" starts at ¥10,000/month (excl. tax).
Infomart is not a product built around generative AI; it is a platform that digitizes the transactions themselves. AI is used in AI-OCR, which reads paper/PDF invoices and purchase orders and turns them into data, and in the AI business-analysis service "IMAgent", whose beta launched on August 26, 2026 (ask questions about your transaction data in a chat and get analysis back; for paying Invoice users, beta free of charge).
Not "sending," but completing it on screen
Paper and PDF invoices take effort to print, stuff, and mail, and to enter and store on the receiving side. Infomart lets both parties exchange data on the same platform, so both issuing and receiving are completed on screen. Because trading partners can join for free, adoption spreads easily, and the strength is being connected to a network of 1.3M+ companies.

- The receiving side must enter and store data

Infomart states there are no system maintenance or renewal fees after adoption. "BtoB Platform Contracts" publishes a price list (as of November 2026, official pricing page).

2025, on the platform

Jun 2025, Tokyo Shoko Research
The BtoB Platform is used by more than 1.3M companies, and its annual transaction value for 2025 exceeded ¥71 trillion (official announcements, July–October 2026). It connects with 50+ systems such as OBC, Yayoi, PCA and Concur, and with Peppol.
How it differs from other BtoB / invoice services
Invoicing takes many forms — "a feature of accounting software," "a service specialized in receiving," and so on. Infomart's distinction is being a network-type service that supports both issuing and receiving, with partners joining for free, and its overwhelming scale of use.
| Aspect | Infomart | Accounting software (freee / MoneyForward) | Receiving-focused (Bill One, etc.) |
|---|---|---|---|
| Purpose | Digitize B2B transactions (issue & receive) | Bookkeeping / accounting / closing | Receiving & digitizing invoices |
| Network | Partners join for free (1.3M+) | Centered on one's own accounting | Focused on receiver efficiency |
| Strength | No.1 share; food-industry commerce | Accounting/back office overall | Unifying the receiving workflow |
For the back office overall, see freee or MoneyForward Cloud and Yayoi; for invoice AI-OCR, see invox (Infomart formed a business alliance with invox Inc. in January 2026 and is co-developing the integrated accounting solution with it). For companies that want to bring partners on board and digitize invoicing and ordering together, Infomart is a strong choice.
