How it works
CarTrawler car rentals inside your booking engine
CarTrawler is a B2B mobility platform that supplies car rentals and ground transportation to travel brands. A CarTrawler API integration with PHPTRAVELS puts that inventory in your own search and checkout: customers and agents compare vehicles, see inclusions, deposits and cancellation terms before paying, and your team handles vouchers, cancellations and finance reports in the same admin as flights, hotels and tours. You keep the UI, the customer data and the workflows.
- Confirm your commercial scope and markets with CarTrawler
- Receive credentials and set up the test environment
- Map search, pricing, deposits and policies to your checkout
- Run booking, voucher and cancellation test cases
- Go live with monitoring and post-booking support processes

Search and pricing
CarTrawler vehicles with rates, inclusions and deposits
Each result shows what drivers check before they pay: the vehicle class, what is included, the payment mode, the deposit and the cancellation terms.
- CDMRCompact · Manual5 seats · 2 bags · Air conditioning–per rental
- CDARCompact · Automatic5 seats · 3 bags · Full to full fuel–per rental
- IFARIntermediate SUV · Automatic5 seats · 4 bags · Theft protection included–per rental
Search by location and date
Live vehicle availability for airport and city pickup points, with drop-off, dates and times.
Inclusions in plain language
Insurance cover, exclusions, fuel policy and mileage limits shown before the driver pays.
Driver requirements
Age, licence and ID rules displayed at checkout, so problems surface before pickup, not at the counter.
Prepaid and pay-at-counter
Both payment modes where the market allows them, with deposits, security holds and extras as separate lines.
Vouchers with pickup instructions
Booking reference, pickup instructions, supplier contact and a snapshot of the terms on every voucher.
Reprice before charging
If the rate changes between search and booking, the customer confirms the new price before payment is taken.
Booking lifecycle
From CarTrawler search to reconciled booking
Car rentals fail in production when only search and booking are built. PHPTRAVELS covers the steps after checkout as well.
Search
Live vehicle availability by pickup location, dates and times.
Price
Rates, inclusions, deposits and policy rules shown with your markup.
Book
Instant reservation with a supplier reference and booking status.
Manage
Booking lookup, voucher resend, changes and cancellations with status tracking.
Report
Bookings, revenue, commissions and payouts by date, supplier and channel.
Multi-vertical journeys
Cars next to flights, hotels, tours and transfers
CarTrawler runs inside the cars module, so rentals become part of the whole trip rather than a separate system.

Self-drive vehicles and ground transportation from your CarTrawler agreement, in your own search.
Checkout upsells and bundles
Offer a car with every flight or hotel booking, and airport pickup with every stay.
