Short answer

Buy for a general scheduling workflow. Build only when scheduling rules are part of the product itself or create meaningful differentiation.

What a good-enough build includes

  • Availability rules and timezone handling
  • Calendar read/write integration
  • Booking, rescheduling, and cancellation
  • Email notifications
  • A small administration surface

The expensive edge cases

Recurring availability, daylight-saving transitions, calendar conflicts, payment failures, and reliable notifications make this less trivial than the first prototype suggests.

Who should build

Vertical SaaS products where booking logic is embedded in the core workflow, or companies whose volume makes per-seat or per-booking pricing structurally unattractive.
