What is Stampli?
Founded in 2015 and headquartered in Mountain View, California, Stampli is an AI-powered procure-to-pay platform for finance teams. It serves 1,800+ customers, processes 400,000+ invoices weekly, and has raised $148 million.
Stampli is an ERP-connected procure-to-pay platform built around the invoice as the working record. Finance teams capture invoices from email, uploads, portals, CSV and other configured channels, then use one workspace for coding, matching, approvals, vendor conversations, documents and payment status. Its embedded Stampli AI, known as Billy, learns business coding and routing patterns while the ERP remains the system of record. The product covers the invoice-to-pay workflow without requiring teams to replace or rework their ERP.
The platform combines invoice capture, AI-assisted coding, purchase-order matching, approval workflows, fraud and duplicate checks, vendor management, procurement, payments, cards, reporting and audit trails. Its 70+ ERP integrations include API, bridge and file connection methods, and implementation is positioned as weeks rather than months. The breadth is useful for complex, multi-entity finance operations, but pricing is not published and teams should validate the exact ERP connector, payment options and configuration effort during sales.
Stampli is aimed at mid-market and enterprise finance teams with high invoice volume, distributed approvers, multiple entities or complicated ERP environments. The company says it serves more than 1,800 customers and has processed more than $390 billion in cumulative spend. Pricing is quote-based, with accounts payable, procurement, payments, cards and vendor-management capabilities packaged as selectable platform components rather than public self-serve tiers. There is no advertised free plan or trial on the pricing page.
