Visa, BILL, and Billtrust have launched the first live pilot in which trusted AI agents initiate and complete approved buyer invoice payments end-to-end through supplier portals. Announced October 20 at Money20/20 in Las Vegas, it targets a stubborn manual step in B2B payments: the human who still has to log into a supplier portal and key in a payment that was already approved. It is the first live pilot to complete approved invoice payments end-to-end through supplier portals with trusted agents, and it is processing real transactions with participating BILL buyers and Billtrust suppliers.
Highlights#
-
How the flow works. A buyer approves an invoice in BILL. BILL's registered Payment Agent, enrolled through Visa's Trusted Agent Protocol and Agentic Directory, uses tokenized payment credentials and controls tied to that approved instruction. When it reaches a Billtrust supplier portal, the Visa protocol authenticates the agent so it can complete the payment without a separate login or shared portal credentials.
-
Agent identity replaces CAPTCHA. The authentication can satisfy the bot-blocking protections portals historically relied on. Suppliers keep their existing acceptance policies and reconciliation data while recognizing payments from verified business agents.
-
Humans authorize, agents execute. The agents are not choosing which invoices to pay. Buyers approve first; agents automate the last manual step. Finance teams get back the time spent keying payments into portals, and Billtrust suppliers see faster payment and improved cash flow.
-
Distribution is the interesting part. BILL serves nearly 500,000 businesses and Billtrust powers accounts receivable for a broad buyer network, giving the pilot a ready-made path beyond the initial participants if it scales.
Why it matters#
The pilot reframes what needs to be true for agent-to-agent commerce: not just payment rails, but a way for one company's system to verify an agent's identity and authority before releasing funds. The pilot is a wager that trusted agent access becomes as important as the payment rail itself. No transaction volume or commercial rollout dates have been disclosed.
