Where each one falls short

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

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.

Orb

  • Custom pricing model requires sales consultation, no transparent public pricing
  • Pricing based on both events and billing volume adds complexity to cost estimation
  • Enterprise-focused positioning may be overkill for simple subscription use cases
  • Requires integration with existing accounting systems for full value
  • Limited information on free tier or trial availability
