“Can an invoice-collaboration tool evolve into the dominant procure-to-pay operating system for mid-market finance teams by embedding payments, cards, and AI into one workflow?”
Stampli started in 2015 as an AI-powered invoice collaboration tool bridging accountants, approvers, and vendors around invoice-level discussions. It expanded from pure AP automation into payments (Stampli Direct Pay, domestic ACH/check + international wires in 100+ countries), then into virtual cards (Stampli Card for AP and expense), and finally into a full procure-to-pay suite with procurement, vendor onboarding, expense management, and the Billy AI agent. Today it positions itself as an end-to-end intelligent P2P platform for mid-market finance teams, not just invoice automation.
Stampli moves money over ACH.
Stampli's cards run on Visa and Mastercard.
Stampli integrates with QuickBooks Online, QuickBooks Desktop, NetSuite, Sage Intacct, Sage Intacct Construction, Sage 100, Microsoft Dynamics 365 Business Central, Microsoft Dynamics 365 Finance and 6 others.
The Embedded Finance Index 2026 maps 3 layers in Stampli's stack: Money movement (ACH); Card network (Visa and Mastercard); Accounting (QuickBooks Online, QuickBooks Desktop, NetSuite, Sage Intacct and 10 others).
Stampli was founded by Eyal Feldman and Ofer Feldman and is founded in 2015, headquartered in Mountain View, California, United States.
Stampli has raised $148M in total (latest round: Series D, October 2023).
