PromtysLog inBuild my website ↗RentSyst runs your fleet, prices and orders; Promtys builds the public website on top of it. When you connect, Promtys installs the official RentSyst WordPress plugin, imports your company settings, locations and fleet, and generates a site with a home page search by pick-up and return location, a fleet page with filters and a page for every vehicle with specs, a price table and an availability calendar. Customers book through RentSyst's own booking form, which checks availability and prices for their dates and creates the order in RentSyst. Everything else you change by typing in the AI chat.

Import vs. Live
What is imported and what works live
Some RentSyst data is copied to your site when it is created, some is requested from RentSyst while the customer books.
| Data | How it reaches your website |
|---|---|
| Company logo, locations, delivery zones and booking settings | Imported when the site is created |
| Working hours | Taken from your first RentSyst location when the site is created |
| Vehicles: photos, specs, groups and prices | Imported when the site is created |
| Availability calendar on vehicle pages | Live — requested from RentSyst when the page is opened |
| Availability, price, extras and insurance in the booking form | Live — requested from RentSyst while the customer books |
| New orders | Live — created in RentSyst |
| Quick requests | Live — saved as contacts in RentSyst |
Added a car or changed prices in RentSyst? Open your WordPress dashboard from Admin Panel in the builder, go to Rentsyst and click Synchronize Fleet to import the fleet again; company settings have their own Synchronize settings button.
Why build with Promtys + RentSyst
RentSyst runs your operations. Promtys turns it into a website that wins customers.
Live where it matters
Availability and the price for the customer's dates are checked in RentSyst at the moment of booking, and every order is created there, so there is nothing to copy over by hand.
A page for every vehicle
Each vehicle gets its own page with specs, prices, WebP photos, an SEO title, a meta description and structured data — content search engines can read, which a booking widget on its own does not give them.
Up to 20 site languages
Pick your site languages when you create the site. The default language is taken from your RentSyst account, and every vehicle gets a page in each language.
Direct bookings on your domain
Customers book on your own website, in a booking form styled to match it, and the order goes straight into RentSyst. Promtys charges no commission on bookings.
How It Works
How to connect RentSyst to Promtys
Click Create Website in RentSyst
In your RentSyst dashboard, click Create Website and Promtys opens with your company already linked. Or sign up on Promtys and enter your RentSyst API Client ID and Client Secret.
Name the site and pick languages
Promtys creates your account and suggests a site name and subdomain from your company. Choose the site languages and click Create Site.
Wait while your fleet is imported
Promtys installs the RentSyst plugin, imports your company settings, vehicles and photos, and sets up the booking page.
Personalise and go live
Adjust texts, photos and design in the AI chat and connect your own domain when you are ready.
What the integration does not do yet
Better to know before you connect.
Fleet changes in RentSyst (new vehicles, photos or prices) are not synced automatically — click Synchronize Fleet in the RentSyst plugin to import them again.
On a multi-language site, vehicles imported after the site was created appear in the default language only.
The site's working hours are taken from your first RentSyst location.
Promtys does not process payments itself: the booking form offers the payment methods set up in your RentSyst account.

Frequently Asked Questions
Can I build a website that syncs with RentSyst?+
Yes. Promtys connects to your RentSyst account, imports your fleet with photos, specs and prices, and builds a car rental website around it. Bookings go through the official RentSyst booking form, which checks availability live and creates each order in RentSyst.
How do I connect RentSyst?+
Click Create Website in your RentSyst dashboard and Promtys opens with your company already linked. Or sign up on Promtys and enter your RentSyst API Client ID and Client Secret.
How is this different from installing the RentSyst WordPress plugin myself?+
Promtys uses the same official RentSyst plugin and booking form, and builds the rest of the website for you: design, home page search, a fleet page with filters, a page for every vehicle, SEO settings, languages and hosting. With the plugin alone, you need your own WordPress site and build those pages yourself.
Do bookings made on my website appear in RentSyst?+
Yes. The booking form creates the order directly in RentSyst when the customer books. Quick requests sent from the site are saved in RentSyst as contacts.
What happens when I add a car or change prices in RentSyst?+
Availability and the price for the customer's dates are always checked live in the booking form. The fleet itself — vehicles, photos, specs and the prices shown on vehicle pages — is imported when the site is created. To bring later changes to the site, click Synchronize Fleet in the RentSyst plugin in your WordPress dashboard.
Does it work with several locations?+
Yes. All locations from your RentSyst account can be chosen for pick-up and return in the search and the booking form, and returning to a different location works if you allow it in RentSyst. The site's working hours are taken from your first location.
Can customers pay online?+
The booking form offers the payment methods set up in your RentSyst account. Promtys does not process payments itself.
Which vehicle types are supported?+
Whatever is in your RentSyst fleet. Your RentSyst vehicle groups become fleet filters, alongside transmission and fuel type, and every vehicle gets its own page.
