Stampli is an accounts payable automation platform differentiating through its AI assistant Billy the Bot — an AI that learns each company's AP processes, vendor relationships, and coding patterns to automate invoice processing intelligently. Billy the Bot ingests invoices from any source (email, scan, EDR, vendor portal), extracts data using AI, automatically codes invoices by learning from historical coding patterns, suggests GL codes and cost centre assignments, and routes invoices to the appropriate approvers based on the company's approval hierarchy. The learning approach means Billy gets smarter over time — recognising recurring vendor invoices and applying consistent coding automatically without manual intervention. AP Collaboration is Stampli's key design choice — invoice approvals, questions, and discussions happen in context alongside the invoice image rather than in separate email chains, reducing the back-and-forth communication that delays AP processing. Stampli integrates with 70+ ERP systems — maintaining the existing ERP as the system of record rather than replacing it. With customers including Autotrader, Zendesk, and Coupa, Stampli validates across automotive, technology, and procurement for AP automation.
Stampli AI runs as ml platform software built around text and data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api.
