Tour Booking System Cost: Custom Build vs OTA Commission

Most tour operators in Phuket/Krabi depend on Klook, GetYourGuide, and Viator — these platforms take 25-30% commission on every booking. For an operator with 10M+ THB/year revenue, that’s 2.5-3M THB lost annually.

Your own booking system reclaims that and grows customer LTV through direct relationships.

Why Owning Your Tour Booking System Matters

Margin Reclaim

• Klook commission: 25%
• GetYourGuide: 22-30%
• Viator: 25%
• Direct booking: 2-3% (payment gateway fee)

The 20%+ gap goes straight to margin = immediate revenue lift after migration.

Customer Data Ownership

• Direct booking = you have customer email + phone.
• Repeat bookings become possible because you can contact past customers directly.
• Real lifetime value tracking.

Brand Authority

• Customer books on your site = they remember your name.
• Klook/GYG = customer remembers the platform, not you.

Scenario: A Krabi Tour Operator

Picture an operator running a few dozen tours mainly through Klook + GetYourGuide.

Before:

• Most bookings arrive via OTAs, so a large share of each sale goes to commission
• Very few direct bookings
• A small customer email list

After a Custom Build:

• A growing share of bookings comes in direct, with no OTA commission on them
• Margin per direct booking improves accordingly
• The customer database grows with every booking
• The build cost is gradually paid back by the commission saved
