The short version

  • Only Apple Calendar has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; Apple Calendar offline sync via USB has reported issues with duplicated events when syncing between macOS and iOS
  • They diverge on capability: Adyen covers Payment processing, Apple Calendar covers Event management.

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

Apple Calendar

  • Offline sync via USB has reported issues with duplicated events when syncing between macOS and iOS
  • No granular calendar exclusion option; iCloud syncs all calendars together with no selective sync
  • Limited offline functionality for non-iCloud calendars
