Car Rental Websites and Reservation Systems: Hosting, Languages and Plans

By Car Rental Solutions · October 16, 2026 · 6 min read

Car rental booking engine flow from availability search to confirmation on a rental company website

Short answer: the Car Rental Solutions reservation system is fully API-based. You can put it on a complete rental website we provide, add just the booking engine to the site you already have, or build on the API yourself, and you can run reservation sites on several domains under one account. Every plan includes API access. Option A covers a bilingual reservation website, Option B three languages and Option C six, and we can add another language or build a custom website on request.

Your website is where most rental bookings start, and the reservation system behind it decides whether a visitor can actually book. This guide explains how the website, the reservation system and languages work in Car Rental Solutions, and what each plan includes.

Three ways to put reservations on your website

OptionWhat you getBest for
Complete rental websiteA website with the reservation system built in, connected to your fleet, rates and paymentsAgencies without a site, or replacing an old one
Booking engine on your current siteThe reservation system added to the website you already have, wherever it is hostedAgencies happy with their current design or web developer
APIYour developer builds a custom booking flow on the car rental API, generated from the Integrations section of your control panelCustom sites, apps, web agencies and partners

All three read from the same back office, so every booking lands in your control panel with the right vehicle, rate and extras. Developers can start with the booking API quickstart.

Host your site anywhere, on as many domains as you need

Because the reservation system is API-based, it does not tie you to one website builder or one host. Your site can live on WordPress, a static host, a custom build or a site we make for you. Under one account you can also run reservation systems on more than one domain, for example:

  • a separate website for each city or airport you serve
  • a second brand, such as a luxury or van rental line
  • a Spanish-language domain alongside your English one

Every domain's bookings arrive in the same control panel, so your team manages them in one place.

Reservation website languages by plan

PlanPriceReservation website languagesExample
Option A$69.95/month2English and Spanish
Option B$99.95/month3English, Spanish and Brazilian Portuguese
Option C$179.95/month6English, Spanish, Brazilian Portuguese, Icelandic, Chinese and French

Available languages are English, Spanish, Brazilian Portuguese, Icelandic, Chinese and French. If you need a reservation language that isn't on the list, we can add it on request. Confirmation emails go out in the language the customer booked in, and rental agreement templates can be multilingual.

Custom websites on request

Option C includes a custom website designed for your brand, with hosting, new pages and campaign landing pages. Agencies on Option A or B can also ask us to build a custom website. Either way, the reservation system works the same, so you can start on your current site and move to a custom one later without changing how bookings work.

How to choose

  • You already have a website you like: add the booking engine to it. Any plan works.
  • You need a site and serve English and Spanish renters: Option B adds a basic website and a third language. Option A covers two languages if you keep your own site.
  • You want a branded site with marketing pages and six languages: Option C.
  • You have a developer or agency building something custom: use the API on any plan.
