What is Visa, BILL and Billtrust Trusted AI Agent B2B Invoice Payments Pilot?

Accounts payable is the work of paying the money a business owes its suppliers, and much of it still involves manual steps such as keying details into supplier payment portals. Those portals are often built for human logins, which makes it hard for software to complete an approved payment on its own. This pilot tests letting an AI payment agent be recognised by a supplier portal, using Visa's Trusted Agent Protocol, and pay a specific invoice with tokenized payment credentials (stand-in codes that replace the real payment details) instead of a shared login. Visa, BILL (buyer side) and Billtrust (supplier side) announced it on October 20, 2026.
