How RentalOS supports your rental business

A new enquiry needs a vehicle, a rental period and customer details. RentalOS connects these in a reservation. Use the fleet calendar to review your schedule and the reservation record to manage each rental.

Review vehicle schedules

Assign reservations to vehicles and rental periods. Check the calendar when planning a new enquiry.

Connect the customer

Link the reservation to an existing customer record so contact details stay with the rental process.

Prepare the contract

Create a contract from the reservation, review the transferred details and add the final rental conditions.

How it works

  1. Choose a vehicle and rental period.
  2. Assign the customer and save the reservation.
  3. Transfer it to a contract and review the rental details.
