The availability engine is the hardest pure function in the platform. We wrote it that way. 100% test coverage, DST-aware, timezone-correct, and ties cleanly into your queue on the day of the visit.
Customers pre-auth a card at booking time (Stripe PaymentIntent with manual capture). If they show up, the hold is released — no charge. If they no-show, the policy fee is auto-captured 15 minutes after their missed start.
None of that "charged an hour before my appointment" surprise. Smart timing, zero friction for real customers, teeth for the ones who waste your slot.
Walk-ins in the queue, booked appointments in the calendar, and a clean bridge between the two. When a booked customer arrives, they appear in the queue at their reserved slot time — zero re-typing, zero double-entry.
Your barbers see a single unified list of who's next, whether that customer walked in or booked three weeks ago.
