Visa, BILL and Billtrust bring agent payments into supplier invoice portals

A live pilot connects approved buyer payment instructions with authenticated agents and supplier-controlled invoice payments.

Visa, BILL and Billtrust announced a live pilot on 20 October that allows trusted AI agents to complete approved buyer invoice payments through supplier portals. The collaboration tackles a familiar business-payment task: an invoice is approved, but someone still needs to enter a supplier portal and finish the payment.

In the announced flow, BILL's Payment Agent is registered through Visa's Trusted Agent Protocol and Agentic Directory. It acts using tokenised payment credentials and controls aligned with the buyer's approved instructions. On the receiving side, Billtrust recognises the authorised agent and applies the supplier's acceptance policy.

Identity travels with the payment task

The arrangement is designed around an identified buyer, a recognised agent and a specific invoice. It gives participants visibility into payment authorisation and completion without sharing a supplier-portal login. The protocol lets the portal recognise the approved automated transaction through a purpose-built access path.

That is a practical extension of agentic commerce into accounts payable and receivable. A buyer's payment approval becomes an instruction that can be carried into another organisation's interface. The supplier retains a role in accepting the payment, while the agent completes the operational steps connecting the two.

A connected accounts workflow

Consider the sequence from a finance team's perspective. The invoice is received, reviewed and approved. A payment instruction identifies what should be paid. The agent carries out that instruction in the supplier's portal, and the resulting transaction can be reconciled against the invoice.

The pilot concentrates on that final portal step. It brings together the accounts-payable platform, payment network and accounts-receivable platform rather than asking a single agent to replace the whole finance process.

The product direction is clear: business automation is moving from producing a recommendation to completing a recognised transaction between systems. For software vendors building around invoices, the useful integration points are the buyer's approval, the supplier's acceptance and the recorded completion of the same payment task.
