Booking System challenges we solve
Common booking system issues in apps built with Devin or Claude Code.
Double-booking prevention
Two customers booking the same time slot simultaneously is the most critical failure mode. AI-generated booking logic often has race conditions — checking availability and creating the booking aren't atomic, so two requests can both see the slot as available and both succeed.
Timezone handling
If your provider is in New York and your customer is in Los Angeles, a '2 PM appointment' means different things. AI tools store times in the server's timezone or the developer's local timezone, causing bookings to appear at wrong times for users in other timezones.
Calendar integration and availability
Providers have existing calendars (Google Calendar, Outlook) that affect their availability. Without two-way calendar sync, providers get double-booked with their personal events, or manual availability management becomes a full-time job.
Payment and cancellation policies
Bookings often require deposits or full prepayment. Cancellation policies (full refund within 24 hours, 50% after that, no refund day-of) need precise time-based logic. AI tools implement basic checkout but not the nuanced refund rules that booking businesses need.
Confirmation and reminder notifications
No-shows kill booking businesses. You need immediate booking confirmations, reminders at 24 hours and 1 hour before, cancellation notifications, and rescheduling flows. AI tools send a confirmation email at best — the full notification pipeline is usually missing.
Recurring bookings and scheduling rules
Weekly appointments, buffer time between bookings, lunch breaks, holidays, and maximum bookings per day are all scheduling rules that AI tools don't implement. Without these constraints, your calendar becomes unmanageable for providers.
Which is better for booking system?
Devin
Well-defined, isolated tasks where autonomy is valuable — bug fixes, migrations, proof-of-concepts. Best when you have clear requirements and can review the output thoroughly before merging.
Devin code reviewClaude Code
Complex features, refactoring, and production codebases where code quality matters. Best when you want AI power with human oversight for architectural decisions.
