The Fleet Operating System for Car Rental, immune to double-bookings & scheduling chaos.
A fleet calendar on one screen, a database that refuses overlapping confirmed bookings, a yard operations board for field staff, and a storefront that takes booking requests from your renters.
Managing rental fleets on paper and WhatsApp groups costs you daily
Double bookings, late returns, and blind fleet availability lead to lost revenue and customer disappointment.
Double-Bookings & Scheduling Conflicts
Promising one car to two different customers due to overlapping verbal commitments and disorganized desk calendars.
Unnoticed Overdue Returns
Vehicles due back at noon that remain on the road while the next customer arrives for pickup.
Blind Yard & Fleet Availability
Not knowing which cars are ready, which need servicing, and which are currently on the road at a single glance.
No Instant Rental Storefront
Customers wanting to view daily/weekly/monthly rates and book online are forced to make repeated phone inquiries.
A car cannot be booked twice
A second booking overlapping the same car is refused in the database.
Don't take our word for it. Try to break it.
In the rental demo, the Porsche 911 Carrera S is already booked for the next few days. Open it and try to book the same car for those same dates.
It will refuse — not because we added a warning in the interface, but because the database itself will not accept two overlapping confirmed bookings on one car.
And that is exactly what we promise, no more: two overlapping confirmed bookings, in the database. A booking agreed over the phone and never entered is not a booking the system knows about — and our terms of service say the same thing.
Open the demo and tryKnow where every car is, and when it comes back.

A booking storefront for your customers
A branded rental site where customers select rental dates, choose vehicles, review insurance options, and request bookings.
- Daily, weekly, and monthly rates display
- Security deposit & insurance terms transparency
- Add-ons you define yourself, by name and price - we never suggest one you did not set
A car cannot be booked twice. Ever.
The database itself refuses to write a confirmed booking that overlaps another confirmed booking on the same car. The refusal comes from the engine rather than from code that can be forgotten or bypassed, so it holds under concurrent requests, through staff error, and against a manual edit.
Once a booking is recorded and confirmed, its dates are held — and nobody sees them offered as free again.
Isolation between dealerships is enforced in the database, and we test it automatically: a real second dealership signs in, and is refused.
No apology to a customer who arrives to find their car already rented — as long as the booking is in the system.

From car to customer.
Seven steps, all inside Caros. No spreadsheets on the side, and no information living in one person's head.
Add the car
Photos, specs, price. The listing copy is written for you in Arabic and English.
It publishes
Its own page, in your name and your brand.
A customer finds it
From search, from a link you send, or from the QR code on its windscreen.
They open the page
Photos, specifications, price and the monthly instalment - before they ask.
They enquire or book
A question, a viewing, or a rental booking with real dates.
Your team is notified
On their phones, the moment it arrives. The lead is stored before the conversation starts.
The conversation begins
On WhatsApp, with your team already knowing which car, who asked, and when.
The details that make Caros a product, not a website template.
Small things nobody puts in a proposal, and you notice in the first week.
Analytics per vehicle
A car viewed constantly that nobody asks about? Check the price. One that is asked about and never free? Buy another.
A car in service leaves the calendar
Set the date it comes back and it disappears from availability until then. It returns to the road when a person says so, not when a date passes.
Customers track their own booking
A private link showing their booking and its dates. Fewer phone calls, more confidence.
And your showroom is in the directory, with no extra work.
The Caros Directory is a public map of showrooms and rental offices that people search by area. In the cities it covers, your business appears with a Caros showroom card.
More than 30 showrooms and rental offices in the directory
- A card in your colour and logo, with a "Browse cars" button to your storefront
- Name, numbers and opening hours update from your dashboard automatically
- Distinct in look, never in rank — the directory has one order for everyone

What every dealer asks before signing
If your question is not here, just ask it — the answer arrives faster than reading a page.
Do I run the site myself, or do I need you for every change?
Entirely yourself. You add cars, edit prices and photos, and change your site’s copy — and the site editor shows you the real storefront beside the form as you type. No developer, no waiting.
Can the same car be booked twice?
No. A database constraint refuses to write a confirmed booking that overlaps another confirmed booking on the same car. The refusal comes from the Postgres engine, not from code that can be skipped or forgotten.
Is the site and my data mine?
Yes. The storefront carries your brand, and your cars and customers are your data. We take no commission on your sales, however much you sell.
Is Caros for selling or for renting?
Both, and for those who do both. Your business type decides what you see: a showroom is never asked about rental days, and a rental desk is never shown an instalment schedule.
How long does launch take?
Days, not weeks. You send your brand and your cars, we set up your platform, and you go live. Starter presets fill the whole storefront copy in one click, so you edit rather than write from nothing.
Can I connect my own domain?
Yes, on Pro and Business. Essential launches on a clean subdomain in your name.
Can my staff reach everything?
Not unless you want them to. Four roles — owner, admin, editor and staff — and every permission is enforced in the database itself, not by hiding a button in the interface.
Ready for a fleet calendar that cannot book one car twice?
We set up your fleet, your rates and your pickup points, and bookings start. Days, not weeks — and no setup fee.
