Mercoa

aid: mercoa
name: Mercoa
description: Mercoa is an embedded AP and AR platform that vertical SaaS companies use to launch AI-powered BillPay and invoicing inside their own products. The platform handles bill ingestion via intelligent email inboxes, vendor onboarding, approval workflows, payment scheduling, branded invoicing, AI-driven collection reminders, and disbursement across ACH, check, virtual card, and BNPL. Builders can choose React components, a hosted iFrame, or pure REST APIs and SDKs depending on how much UI control they need. Mercoa publishes official SDKs for TypeScript, Python, and Java and is backed by Y Combinator. Customers monetize Mercoa through per-user pricing, transaction fees, and premium payment option margins.
