Stampli is an AI-powered accounts payable automation and procure-to-pay platform headquartered in Mountain View, California. Founded in 2014, the company serves more than 1,800 businesses and processes over $150 billion in annual invoice volume. Stampli has raised $148 million in venture funding.
Stampli's core offering centers on invoice lifecycle management — capturing invoices from any channel (email, upload, vendor portal, CSV), automating GL coding and approval routing using its AI engine (branded "Billy"), supporting 2- and 3-way PO matching, and preserving a complete audit trail with all communications, documents, and approvals attached directly to each invoice. Stampli also offers Stampli Direct Pay (ACH, wire, and check payments), corporate charge cards, advanced vendor management, and procurement workflows. The platform integrates natively with over 70 ERPs including NetSuite, Sage Intacct, QuickBooks, SAP, Microsoft Dynamics, Oracle, and Acumatica.
Businesses use Stampli to automate AP processing without replacing their ERP or reworking existing workflows — the platform adapts to how each finance team actually operates, whether centralized, decentralized, or hybrid. Stampli is a common choice for mid-market businesses in high-invoice-volume industries like healthcare, construction, hospitality, real estate, professional services, and manufacturing that need faster invoice processing, stronger controls, and audit readiness without proportional headcount growth.
