Car rental software
RentalOS is a complete car hire management system. Inquiry form, confirmation emails, admin panel, mobile-first — deployed and live in one day.
01
Missed inquiries when you're busy on site
A customer sends a WhatsApp at 3pm. You're handing back keys. By the time you reply it's gone to a competitor.
02
Double bookings because the calendar is in your head
Two customers. Same car. Same weekend. An impossible conversation to have. Avoidable with the right system.
03
Hours lost chasing documents and payments
Licence photos by WhatsApp. Deposit by bank transfer. Manual follow-ups. Every booking takes 30 minutes of admin.
Built for exactly how car rental businesses actually work.
Instant inquiry capture
Customer submits dates, car, and contact details online. You get an email alert immediately. They get a confirmation with their booking reference.
One-tap confirmation
Review the request in your admin panel on any device. Confirm with one click. Confirmation email sent automatically.
Full booking trail
Every status change logged. Documents attached. Notes saved. The full history of every rental in one place.
