Visa Pilots AI Agent Payments With BILL and Billtrust

Visa, BILL and Billtrust have launched a live pilot that lets trusted AI agents initiate and complete approved buyer invoice payments through supplier portals. The pilot is processing end-to-end transactions for participating buyers that use BILL and suppliers that use Billtrust.

The BILL Payment Agent is registered through Visa's Trusted Agent Protocol and Agentic Directory. It uses tokenized payment credentials and controls tied to the buyer's approved payment instructions to issue card payments for supplier invoices.

Billtrust uses the protocol to recognize and authenticate the agent before granting it access to its portal. Visa said this authentication can satisfy protections historically provided by CAPTCHA and other bot blocking, without a separate agent login, and gives both sides visibility into how each payment was authorized and completed.
