The short version

  • Only Bill.com has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bill.com limited customization of approval workflows and user permissions for complex business needs; Medius the sourcing, contract and procurement modules are considerably less developed than the AP core, so buying Medius as a full source-to-pay suite means accepting weak upstream tooling.
  • They diverge on capability: Bill.com covers AP automation, Medius covers Invoice capture and coding.
  • Prices and features above were last checked on 31 August 2026.

Medius

  • A group with several legal entities on different ERPs that wants one AP process across all of themnot Bill.com

  • Replacing a scanning bureau and a shared AP inbox with automated capture and exception-based reviewnot Bill.com

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bill.com

  • Limited customization of approval workflows and user permissions for complex business needs
  • Limited international payment capabilities compared to specialists like Tipalti
  • Customer support response times are slow, with agents often lacking product expertise

Medius

  • The sourcing, contract and procurement modules are considerably less developed than the AP core, so buying Medius as a full source-to-pay suite means accepting weak upstream tooling.
  • Pricing is quote-only and driven by invoice volume, so a business with many low-value invoices pays disproportionately relative to the spend being controlled.
  • Payments are billed on transaction volume separately from the AP subscription, which is easy to omit from a cost comparison against a licence-only AP tool.
  • Private equity ownership since 2017 has produced an acquisition-driven product line, so payments and adjacent capability come from bought-in technology rather than the original platform.
  • ERP integration depth varies sharply by system, and organisations on less common or heavily customised ERPs face integration work that lengthens the implementation.
