Why every car rental booking through an OTA costs you more than you think

OTAs, online travel agencies like Rentalcars.com and similar comparison platforms, play a useful role in the car rental distribution ecosystem. They bring visibility, they reach travellers who don’t know your brand, and they fill gaps in capacity. Many serious operators use them, and that’s not going to change.

But there’s a cost to OTA dependency that goes beyond the commission rate, and operators don’t always add up the full bill.

The commission is just the start

OTA commissions for car rental typically range from 10% to 25% depending on the platform, your contract, and your market. On a $500 rental that’s $50 to $125 gone before you’ve paid a single operational cost. Across a month of bookings, this adds up to a significant portion of revenue you worked for and handed to a platform.

The hospitality industry has been grappling with this dynamic for longer than car rental has, and the lessons are instructive. Major hotel brands have run entire marketing campaigns specifically to push guests toward direct booking. Hilton’s “Stop Clicking Around” campaign is the best-known example. The car rental industry is following the same trajectory. Operators who understand the full cost of OTA dependency are the ones investing in direct channels.

The insurance problem

This is where it gets less obvious and more damaging.

When a customer books through an OTA or broker, they’re often offered insurance at the point of booking: insurance sold by the OTA, not by you. The customer buys coverage, arrives at your counter, and the insurance conversation is already settled with someone else’s product.

The margin problem is clear. You fulfil the rental, the OTA sold the insurance. But the operational problem is worse. When that customer has an incident, they’re dealing with a third-party insurance provider rather than your team. The claims process is slower, more complicated, and frequently frustrating. The customer blames the rental experience, your brand, even when the friction is coming from the insurer they bought through the booking platform. You carry the reputational cost of a process you have no control over.

Insurance is one of the highest-margin add-ons in car rental. Losing it to the booking platform doesn’t just reduce your revenue per rental. It removes one of the most valuable parts of the customer interaction and introduces a post-rental experience you can’t manage.

They’re not your customer

When someone books through an OTA, the platform owns the booking relationship. While you capture the customer’s details at pickup, the OTA holds their booking history, their search behaviour, and crucially their next search. When they need a car again, they open the same platform they used last time.

The loyalty, if any develops, goes to the platform rather than your brand. You’ve paid a commission to bring in a customer who, without deliberate effort on your part, will likely book the same way again next time.

Direct booking customers are different. You acquired them, you have a complete picture of their booking history, and you have the ability to build a relationship over time. You can run a loyalty programme that gives them a reason to return to your site. You can communicate directly with offers, upgrades or important information. You can also offer online check-in to speed up the process at the counter and improve customer experience, whilst lowering your costs. Over a customer’s lifetime that relationship has a value that compounds in a way OTA bookings never will.

The rate parity trap

Many OTA contracts include rate parity clauses, meaning you can’t offer a lower rate on your own website than on their platform. This is designed to prevent operators undercutting the OTA to divert bookings.

The approach that works well in hospitality and translates directly to car rental is value parity rather than rate parity. You don’t offer a lower price. You offer more for the same price: a free upgrade for direct bookers, flexible cancellation, priority counter service. Something that makes the direct channel worth choosing even at the same headline rate.

A note for growing operators

For established operators, the OTA relationship is usually already well understood. The mix is deliberate, the commissions are budgeted, and the focus is on shifting the balance toward direct over time.

We regularly hear from newer, ambitious operators who are considering leaning into OTAs as a way to grow their brand quickly and fill capacity. That’s a legitimate strategy and it can work well in the early stages. The important thing is to go in with clear expectations: understand the full cost, build your direct channel in parallel from the start rather than as an afterthought, and treat every OTA customer as an opportunity to convert into a future direct booker.

The hybrid approach: Kayak, Skyscanner and deep links

One approach we see among Carcloud.com customers sits between pure OTA dependency and pure direct booking: the deep link approach with metasearch platforms like Kayak and Skyscanner.

Here’s how it works. The customer discovers and compares your rates on the metasearch platform, but when they click to book, they land directly on your own website to complete the transaction. The booking happens on your site, in your system, under your brand. You capture the customer data, you control the checkout experience, and you sell your own insurance and extras.

Carcloud.com has direct connections with both Kayak and Skyscanner, which means customers on our platform can take advantage of this without a complex technical integration. You get the visibility and rate comparison traffic from major metasearch platforms, while keeping the booking and the customer relationship on your own site.

It’s not commission-free, but you retain far more of what matters: the transaction, the data, and the customer.

What a strong direct channel looks like

A well-performing direct booking website isn’t just a booking form. It’s the foundation of your entire direct distribution strategy. It needs to be fast, trustworthy, and easier to use than the OTA alternative. It needs to rank well for the searches your customers are doing. It needs to convert the traffic it gets: clear pricing, clear insurance options, a smooth checkout, and a reason to book now rather than go back to the comparison site.

The operators doing this well are not competing with OTAs on price. They’re competing on confidence: a familiar brand, a clear offer, a booking experience that feels reliable.

That’s where a platform built specifically for car rental, with genuine conversion optimisation and SEO built in, pays for itself. Not just in the bookings it takes today, but in the customer relationships it helps you own for the long term.
