Visa, BILL and Billtrust announced they have launched the first live pilot to enable trusted AI agents to initiate and complete approved buyer invoice payments end-to-end through supplier portals.

Until now, many payment portals relied on human authentication requirements that limited how approved payments could be automated. Together, with leading accounts payable and receivable solutions providers BILL and Billtrust, the Visa Intelligent Commerce portfolio helps bridge that gap. Leveraging offerings such as Visa Trusted Agent Protocol, AI agents can now be securely authenticated to credentialed portals. As a result, buyer payments that previously relied on manual entry can be completed by trusted AI agents, while preserving supplier control and oversight.

The flow begins when the authorized BILL Payment Agent — registered using Visa’s Trusted Agent Protocol and Agentic Directory — uses tokenized payment credentials and controls aligned with the buyer’s approved payment instructions to issue payments on behalf of BILL's customers. Supported by capabilities within the Visa Intelligent Commerce (VIC) portfolio, this enables BILL to securely automate card payments for supplier invoices.

Once the payment is initiated, Billtrust leverages Visa's Trusted Agent Protocol to recognize, authenticate, and grant access to the authorized agent, enabling BILL to complete the invoice payment on the customer's behalf. This agent authentication can satisfy the site protections historically provided by CAPTCHA and other bot-blocking mechanisms, without requiring an additional agent login. As a result, Billtrust customers can receive fast portal payments in accordance with their acceptance policy, which can help accelerate cash flow.

“Businesses should not have to choose between automation and control when making payments,” said Mark Nelsen, SVP and Head of Product, Commercial & Money Movement Solutions, Visa. “This pilot applies agentic commerce to a real B2B-payment problem by having trusted agents complete payments across platforms. Working with BILL and Billtrust, we are testing how identity, payment controls and transaction visibility can make that model work.”
