Frequently asked questions
AvidXchange scores F on Supergood's API Report Card. AvidXchange offers partner-gated REST APIs and prebuilt UI components for embedding AP and payments into ERPs, with 240+ published accounting integrations. There is no public developer portal, API reference, or self-serve key issuance; access comes through bilateral partner contracts.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
AvidXchange is a Charlotte, NC-headquartered accounts payable (AP) automation and B2B payments platform founded in 2000 by Michael Praeger.
Vertical: Financial Services (AP automation, B2B payments, spend management). Invoice receipt via email, mail-to-PO-box, EDI, or supplier portal upload. OCR + human-in-the-loop invoice indexing (header data, line items, GL codes). Configurable multi-step approval workflows with full audit trail.
High within mid-market AP automation. AvidXchange and Bill.com together account for the majority of mid-market AP automation share in North America (AvidXchange is cited at ~18% market share).
Invoices: header (vendor, invoice #, date, amount, due date, PO ref), line items, GL/dimension/job coding, attached images, approval state, audit history. Suppliers: name, address, tax ID, payment method preference, AvidPay enrollment status, remit-to addresses, 1099 status.
Founded in 2000; ~26 years old as of 2026. AvidXchange predates the modern SaaS AP wave by roughly a decade, and the platform shows it in places, the AvidInvoice UI has been criticized as dated and slow vs. AI-native entrants like Stampli and Vic.ai.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Not that we could find. As of August 2026 there is no official AvidXchange MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. AvidXchange doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
