I run a small travel and tour business that offers customizable tour packages, transportation, and guided experiences. Most bookings currently happen via Facebook, WhatsApp, and direct messaging.

I’m planning to build a mobile app (Android first, possibly cross-platform later) and would like ideas that are technically feasible and aligned with a service-based tourism business.

Current setup:

  • Custom tour packages

  • Manual booking confirmation

  • Payments via bank transfer / e-wallet

  • Drivers and guides assigned manually

  • Customer communication via chat apps

Goals for the app:

  • Improve booking efficiency

  • Automate confirmations and reminders

  • Reduce manual coordination

  • Improve customer experience

  • Possibly support resellers or agents in the future

Constraints:

  • Small team (no in-house developer yet)

  • Limited budget

  • Need something scalable

  • Prefer starting with MVP features

Questions:

  1. What core features should be included in an MVP for a travel tour booking app?

  2. Should I build native (Kotlin/Swift) or use cross-platform (Flutter/React Native)?

  3. What backend architecture would you recommend for booking + scheduling (Firebase? Node.js + PostgreSQL?).

  4. Any recommended APIs for payments and maps integration?

  5. How would you design the database structure for tours, schedules, vehicles, and guides?

I’m looking for practical, implementation-focused suggestions rather than general business ideas.
