Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Adyen
- There is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic
- Published fees are indicative rather than a rate card, with real pricing negotiated
- Interchange++ means the card cost varies per transaction rather than being a single predictable percentage
- Alternative payment methods carry their own rates on top, such as 3.3 percent plus $0.10 for American Express in North America
Medius Expense
- The Expensya name is being retired, so contracts, logins and support articles change identity mid-relationship and internal documentation has to be rewritten.
- It is now a module inside an accounts payable suite, so expense-specific roadmap items compete with supplier invoice work for engineering time.
- Pricing is not published and is discounted against bundling with Medius AP, which makes standalone expense quotes less competitive than they look.
- Strength is concentrated in Europe and the Maghreb; North American and Asian tax and mileage handling are thinner than the European coverage.
- It does not issue cards, so real-time spend controls are absent and it relies on card feed reconciliation after the fact.
