Travel app development cost
A booking app against one supplier API runs $85,000 to $145,000. A multi-supplier travel platform with its own availability cache, payments and cancellation logic runs $250,000 to $500,000.
Cross-platform mobile, 30 screens, 3 user roles, with the compliance posture this vertical carries.

Compliance and security add $37,291 here
That is 9% of this build, measured rather than asserted: we priced the identical app with no named regime and a baseline security posture, and this is the difference. None of it produces a user-visible feature, and none of it can be retrofitted cheaply.
Regimes that apply in this vertical
- PCI DSSAnyone handling card data. Hosted fields keep card data off your servers and reduce this to a self-assessment rather than a full audit -- which is a large cost difference.
- $4K – $22K audit
- GDPRAnyone offering services to people in the EU or UK, wherever your company is. A US-only product with US-only users is generally outside it.
- $0 – $12K audit
- CCPA / CPRABusinesses over the revenue or data thresholds with California consumers. In practice, most US consumer products at any scale.
- $0 – $8K audit
- ADA / Section 508 accessibilityPublic sector procurement contractually, and in practice any consumer or education product large enough to attract a complaint.
- $6K – $20K audit

What makes travel & hospitality different
Inventory and availability are distributed
Rates and availability live in systems you query rather than own. Caching them without ever selling a room twice is the hard problem in travel software.
Cancellation and change policy is logic
Refund windows, partial cancellations, date changes and fees are a rules engine. Every one of them is a support ticket if it is wrong.
Seasonal peaks
Booking traffic is concentrated into short windows. The architecture has to hold the peak, and you pay for that headroom year-round unless it scales elastically.
Who uses software in this vertical
Each additional role brings its own screens plus a row in a permission matrix that grows faster than the role count — because every new role is a question about every role that already exists.

Four standards of finish
The same app in travel & hospitality, built to four different levels of depth.
| Level | Cost range | Timeline | Hours | Team |
|---|---|---|---|---|
| MVP Prove it works | $250K – $350K | 4.6 – 6.2 months | 2,150 | 7 |
| Standard Production ready | $350K – $490K | 5.5 – 7.6 months | 3,000 | 7 |
| Advanced Built to grow | $450K – $625K | 6.2 – 8.5 months | 3,850 | 7 |
| Enterprise Audited and integrated | $600K – $825K | 7.2 – 9.7 months | 4,950 | 7 |
