How car rental actually works.
Renting a car looks simple from the outside. Behind it sit five journeys most people never see: how a booking travels, where the money goes, the life of the car, how the price is really built, and who carries the risk. Follow each one.

The short answer A car rental booking travels from the site you book on, through a booking engine and often a GDS or XML connection, to the rental company's reservation system, which confirms it. The price you see is the rental company's rate plus the seller's margin or commission, taxes and fees. At the counter, the rental agreement decides who pays if the car is damaged.
Follow the reservation
From a search to a signed agreement, here's every system a booking passes through before you get the keys.
Follow the money
The price you pay is split among several hands before it reaches the company that gives you the car.
Follow the car
A rental car has a whole life before and after your trip - bought, financed, rotated, and resold.
Follow the price
The number you see is the end of a long chain of decisions, not a fixed sticker.
Follow the risk
If something happens to the car, responsibility moves through a chain most renters never see until they need it.
How does a car rental booking work?
You search on a booking site or with a travel advisor. The seller's booking engine asks the rental company's reservation system for cars and rates, often over an XML connection or a GDS. When you book, the rental company confirms the reservation, you get a confirmation or voucher, and the rental agreement is signed at the counter.
Who sets the price of a rental car?
The rental company sets its rates from fleet availability, demand and season. If you book through a broker, agency or travel site, that seller adds its margin or earns a commission, and taxes and fees are added on top, so the same car can show different prices on different sites.
Who do I contact if something goes wrong with a rental booked through a third party?
Start with whoever took your payment, since they hold your booking. Problems at the counter, with the car or with damage are handled by the rental company named on your rental agreement, so keep both contacts handy.
