Visa, BILL, and Billtrust Launch AI Agent Invoice Payment Pilot
Visa, BILL Holdings, and Billtrust have launched the first real-time pilot allowing trusted AI agents to initiate and complete buyer-approved corporate invoice payments end-to-end without manual login or verification.
The pilot registers the BILL Payment Agent using Visa's Trusted Agent Protocol and Agentic Directory, controlling tokenized payment credentials and buyer-approved payment instructions to initiate card payments to vendor portals on behalf of BILL customers. Billtrust uses the same protocol on the vendor side to identify, authenticate, and authorize agents to complete payments.
Previously, many payment portals relied on manual identity verification, limiting the automation of approved payments. This pilot addresses one of the last major manual steps in the accounts payable process, allowing agents to operate without sharing logins or facing CAPTCHA-like bot intercepts while maintaining vendor control and transaction visibility.
The pilot is currently processing real-time end-to-end transactions between participating buyers (using BILL) and Billtrust vendors. The Visa Intelligent Commerce suite supports this process, aiming to address the pain points of manual review and payment of repetitive corporate invoices.
BILL's stock rose about 5.1% in early trading following the announcement, while Visa increased by about 1.4%. The three parties will continue to explore agent payment opportunities, with the scale of the pilot and specific transaction volumes yet to be disclosed.
Corporate finance teams are adopting agent payments to free up manual time and accelerate cash flow, driven by bottlenecks in accounts payable automation; funds and transactions flow through Visa's tokenization and protocol layers, benefiting BILL and Billtrust customers with faster collections and reduced manual operations, while traditional processes relying on manual portal logins face pressure.

Visa has previously collaborated with OpenAI and others to explore consumer-side agent shopping, and this time extends the Trusted Agent Protocol to B2B invoice payments, replacing portal logins with identity protocols and tokenized credentials; similar to earlier attempts to introduce virtual cards or automated clearing in corporate payments, but for the first time achieving end-to-end agent execution across buyer and vendor platforms.
Capital and transactions flow through Visa's Intelligent Commerce layer and tokenized credentials, with BILL agents initiating on the buyer side and Billtrust authenticating completion on the vendor side; the pilot shifts repetitive invoice payments from manual operations to controlled agent execution, aiming to reduce manual time for finance teams while retaining approval control.
This is similar to the paths taken by Stripe, Adyen, and others in payment automation and embedded finance, but Visa chooses to connect existing AP and AR platforms through protocol layers rather than building a full process from scratch; currently in a pilot phase transitioning from rule automation to identity-trusted agent payments, focusing on solving the long-standing bottleneck of portal authentication.
Essentially, this represents a technological substitution and transfer of pricing power: agent identities and tokenized credentials shift the payment execution authority from manual portal operations to a verifiable AI agent layer, with pricing and control determined by Visa's protocols and buyer preset instructions; finance teams transition from executors to supervisors, while the value and friction of manual verification in portals decrease.

Agent identity equals removing manual verification from the payment chain
Tokenization plus protocol equals cross-platform without login
From manual portals to agent execution, control remains at the instruction layer
