Stampli
Billy, the AI employee that runs your invoice-to-pay process
Overview
Stampli handles the full spend lifecycle: procurement requests, invoice capture and coding, vendor management, approval routing, and payments, all inside one system that plugs into QuickBooks, SAP, Oracle, NetSuite, Microsoft Dynamics, Sage and others. Its AI, branded Billy, is trained on a library of 2,700+ ERP-aligned fields, and Stampli says it now handles the bulk of the coding and matching work that used to sit with an AP clerk.
Stampli is built for mid-market and larger finance teams managing real invoice volume ($400B+ processed across its customer base), not solo operators. Every customer goes through a custom quote and a sales conversation before they see a number.
Key Features
AI invoice coding, matching, and approval routing (Billy)

Pros
Genuinely reduces manual AP work; G2 Leader status and 1,500+ five-star reviews
Invoice-level collaboration tools speed up approvals significantly, users report roughly 5x faster processing
Broad, deep ERP integration library
Support team consistently praised as responsive in reviews
Cons
No public pricing anywhere; you must talk to sales to get a number, which is friction for a buyer trying to compare tools
Not built for solo operators or very small teams; cost only makes sense at real invoice volume
Invoices can't be edited once submitted for approval, which creates rework friction
Some users report confusing error messages and payment-timing issues
What Makes It Unique
Stampli's differentiator is putting the invoice itself, not a queue or dashboard, at the center of the workflow: comments, approvals, and Billy's AI all happen right on the invoice image. That's a genuinely different UX from ledger-first competitors like Bill.com or Ramp's AP module.

Tool Information
Pricing
Custom / quote-based - no public flat pricing tier. Stampli requires a sales conversation for a number; unconfirmed how pricing scales with invoice volume.
