Why Booking & Reservation App development is hard to get right

⚠️

Calendar availability logic with timezone support is consistently underscoped — bookings go wrong across timezones

⚠️

Payment capture at booking vs at service is a UX and financial decision with real technical implications

⚠️

Double-booking prevention requires database-level locking — not just UI validation

⚠️

Automated reminders (SMS + email) significantly reduce no-shows but require careful scheduling infrastructure

Frequently asked questions

How do you prevent double bookings?

Database-level locking via Postgres transactions with FOR UPDATE. When a booking is being confirmed, the slot is locked at the DB level — no race condition possible even with simultaneous bookings.

Can you integrate with Google Calendar / Outlook?

Yes — Google Calendar API and Microsoft Graph API for bi-directional sync. New bookings appear in provider's calendar; events blocked in Google Calendar block availability in the booking app.
