AI-assisted source summary · not independently verified. Content standards

BILL, Visa, and Billtrust launched a supplier payment pilot in October, in which AI agents execute payments for buyer-approved invoices on supplier websites. Billtrust uses Visa’s protocol to authenticate the agents, which use tokenized card credentials, while suppliers’ existing payment rules remain applicable. Melio’s agent logs into suppliers’ existing billing or accounts receivable systems, identifies available payment methods, and returns information that helps match invoices.
