# Stampli **Source:** https://geo.sig.ai/brands/stampli **Vertical:** Finance & Accounting Software **Subcategory:** Accounts Payable & Supplier Payments **Tier:** Challenger **Website:** stampli.com **Last Updated:** 2026-04-14 ## Summary Stampli raised 9M+ for AP automation centered on invoice-level collaboration and ERP-native integration, letting finance teams resolve exceptions on the invoice itself (Mountain View CA). ## Company Overview Stampli is an accounts payable automation platform that distinguishes itself in the AP software market by centering its user experience on invoice-level collaboration rather than purely on workflow routing and payment processing. Founded in 2015 and headquartered in Mountain View, California, Stampli has raised more than $79 million from investors including Insight Partners and SignalFire. The company's core insight is that AP invoice exceptions — the cases that require human judgment, clarification, or approval escalation — are best resolved through structured communication directly on the invoice rather than through email chains and disconnected approval workflows.\n\nStampli's platform uses AI, called Billy the Bot, to automate the learning and coding of invoice data, recognizing vendors, GL codes, cost centers, and approval patterns from historical data to reduce manual data entry on routine invoices. When an invoice requires clarification, Stampli centralizes all communication, approvals, and documentation on a single invoice view accessible to finance, department approvers, and vendors, creating a complete audit trail. The platform integrates natively with more than 70 ERP systems including SAP, Oracle, NetSuite, QuickBooks, Microsoft Dynamics, and others, with an API-first architecture that reduces implementation friction.\n\nStampli targets mid-market and enterprise finance teams that process high invoice volumes and struggle with approval delays, lost invoices, and the lack of visibility in traditional AP workflows. The company competes with Tipalti, Medius, Basware, and Coupa in the AP automation space, differentiating through its ERP-agnostic integration approach, its collaboration-first UX, and its AI learning engine that reduces manual work without requiring extensive AP workflow reconfiguration. ## Frequently Asked Questions ### What is Billy the Bot in Stampli? Billy the Bot is Stampli's AI engine that learns from historical invoice data to automatically suggest GL coding, cost center allocation, and approval routing for new invoices, reducing manual data entry and improving processing speed for routine invoices while flagging exceptions for human review. ### How does Stampli handle invoice exceptions and approvals? Stampli centralizes all communication, approval requests, and supporting documentation directly on each invoice in a collaborative view accessible to finance staff, department approvers, and vendors, eliminating email chains and creating a complete audit trail for every invoice decision. ### Which ERP systems does Stampli integrate with? Stampli integrates natively with more than 70 ERP and accounting systems including SAP, Oracle E-Business Suite, Oracle NetSuite, QuickBooks, Microsoft Dynamics, Sage Intacct, and many others, providing pre-built connectors that minimize implementation effort and maintain data fidelity. ### How does Stampli's AI assistant Billy the Bot help with invoice processing? Billy the Bot is Stampli's AI assistant that learns from each company's historical invoice coding patterns to suggest GL account coding, cost center assignments, and approval routing for new invoices. Over time, Billy's suggestions become more accurate and require fewer human corrections, increasing the share of invoices processed with minimal AP team intervention. ### What makes Stampli's invoice collaboration approach different from other AP tools? Stampli centers its interface on invoice-level collaboration — all communications, approvals, and questions related to a specific invoice happen within a comment thread attached to that invoice record. This keeps all context together rather than dispersing it across email threads, making it easy to audit the full history of every invoice decision. ### Does Stampli integrate natively with ERP systems? Stampli is known for ERP-native integrations that sync deeply with the ERP's data structures rather than generic API connections. The company has dedicated integrations for NetSuite, SAP, Sage, Microsoft Dynamics, QuickBooks, and others, with the goal of preserving the ERP as the system of record while adding AP collaboration capabilities on top. ### Does Stampli offer card payment capabilities for vendor payments? Yes. Stampli offers Stampli Direct Pay and a virtual card payment product that allows AP teams to pay vendors directly from within the Stampli platform. These payment capabilities extend Stampli beyond invoice approval into the full AP payment process, giving finance teams an end-to-end AP workflow in a single platform. ### What size companies does Stampli serve? Stampli serves mid-market companies — typically with $10M to $500M in revenue — that have outgrown manual invoice processes but want a faster and less disruptive implementation than large enterprise AP automation platforms. Stampli positions its ERP integration depth and rapid implementation as advantages over competitors that require longer deployment timelines. ## Tags fintech, saas, enterprise, automation, cloud-native, platform, ai-powered, b2b --- *Data from geo.sig.ai Brand Intelligence Database.
