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.

Paddle

  • Paddle charges 5% plus 50 cents on every checkout transaction, which is well above a bare payment processor rate
  • The 50 cent fixed component falls heavily on low value sales, and products under $10 require custom pricing agreed with sales
  • Invoicing is not covered by the published rate and requires custom pricing
  • As a merchant of record Paddle sits between the seller and the customer, so payouts and tax handling run through Paddle rather than the seller's own processor
