Stampli

Stampli is an accounts payable (AP) automation platform built around the invoice itself, with a focus on collaboration and AI. Its core idea is that all communication, documentation, and workflow for each invoice live directly on that invoice, so approvers, AP staff, and others resolve questions in context rather than over scattered emails. Its AI assistant, Billy the Bot, learns an organization's patterns to capture invoice data, code GL accounts, route approvals, and flag issues — reducing manual entry and speeding the AP cycle.

The platform automates the full AP workflow. It captures invoices from any source, uses AI to extract and code line items, routes them through configurable approval workflows with the invoice-centric communication hub, and syncs to accounting/ERP systems (QuickBooks, NetSuite, Sage Intacct, and many others) without forcing a change of your ERP. Stampli also offers integrated payments, corporate cards, and vendor management, extending from invoice processing into paying vendors, with audit trails and controls for compliance.

Stampli serves mid-market and enterprise finance/AP teams that want AP automation that fits their existing ERP. Pricing is not publicly tiered and is quote-based (with a commonly cited entry around $45/month for smaller setups on a month-to-month model), scaling with invoice volume, users, and features. It competes with Bill.com, Tipalti, AvidXchange, and Melio, differentiating on invoice-centric collaboration, its Billy the Bot AI, and broad ERP compatibility.
