The agent does not decide what to pay. Participant numbers and fees are not stated in the announcement.

What Visa, BILL and Billtrust announced
Visa, BILL and Billtrust announced on 20 October 2026 what they call the first live pilot in which trusted AI agents start and complete approved buyer invoice payments end to end through supplier portals. The companies say many payment portals have relied on human authentication, which limited how far approved payments could be automated.
The flow starts with the BILL Payment Agent, which is registered using Visa's Trusted Agent Protocol and Agentic Directory. It uses tokenized payment credentials and controls that match the buyer's approved payment instructions to pay suppliers on behalf of BILL customers. On the supplier side, Billtrust uses the same protocol to recognize, authenticate and admit the agent to its portal. The release says this agent authentication can satisfy the protections that CAPTCHA and other bot blocking used to provide, without a separate agent login. The pilot is live and processing transactions with participating buyers and suppliers.
What the agent can and cannot do
The companies list five controls: an authenticated agent acting for an identified buyer, tokenized credentials instead of shared supplier-portal logins, payment controls tied to the approved instruction, a payment path tied to the specific invoice, and visibility into authorization and completion. The FAQ in the release is explicit that the agent does not make payment decisions. It only executes eligible payments the buyer has already approved, and buyers do not hand over their supplier-portal credentials.
Mark Nelsen, head of product for commercial and money movement solutions at Visa, is quoted saying the pilot tests how identity, payment controls and transaction visibility can make agent-completed payments work across platforms. BILL says nearly 500,000 businesses use its platform, and Billtrust says its network has more than 20 million buyers.
Why it matters
This pilot targets a narrow and controlled case: business payments that already pass through approval workflows, which Visa's FAQ names as the reason B2B is a good fit. It also treats agent identity as a replacement for bot defenses rather than a way around them. A portal that recognizes a registered agent no longer needs a CAPTCHA to tell people from scripts, which is the same problem browser and desktop agents run into on the open web. For suppliers, Visa says the model could bring card payments to portals that mostly received ACH transfers or checks, and could shorten days sales outstanding.
What to watch next
The release gives no count of participating buyers or suppliers, no transaction volume and no date for a wider rollout. It says the three companies will keep exploring agentic payments as the pilot progresses. Whether other accounts payable platforms register agents in Visa's directory will show if the protocol spreads beyond this pilot. Related agent coverage is collected under AI Agents.
What changed
| Before | Paying an approved invoice through a supplier portal often needed an employee to log in and key in card details, because portals relied on human authentication |

| After | A registered BILL agent authenticated through Visa's Trusted Agent Protocol pays approved invoices on Billtrust portals with tokenized credentials, in a live pilot |
| Who it affects | Accounts payable teams using BILL, suppliers accepting payments through Billtrust portals, and card issuers and networks building agent payments |
