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
Calendly
- The free plan allows one event type and one calendar connection, so it cannot handle different meeting formats
- Automated reminders and multiple calendars need Standard at $10 per seat per month
- Round-robin routing, lead qualification and Salesforce integration require Teams at $16 per seat per month
- SAML single sign-on, audit logs and domain control are Enterprise only, starting at $15,000 a year
- Advertised prices are the annual rates
