Kronn ERP for Car rentals
Car rental software with bookings and invoicing
Fleet, bookings, rental agreements and deposits in one program — with the document issued the moment the keys come back.
A car rental business runs on dates: which car is free, when it comes back, how many kilometres it did and what state it returned in. Kronn ERP links the fleet to bookings and rental agreements, and turns every rental into a document — a receipt for individuals, an invoice for companies — through a certified e-invoicing provider, with transmission to myDATA.

05
Deposits
Record the deposit at pick-up and refund it, or offset it against any charges, when the vehicle comes back.

FAQ
Frequently asked questions
Can I see the whole fleet’s availability in one calendar?
Yes. The calendar shows every vehicle and category by day, with bookings, returns and vehicles in for service. A new booking cannot overlap another on the same vehicle.
How do you handle long-term leases to companies?
With recurring invoices: the lease is invoiced automatically every month, emailed to the company and, with a bank connection, the payment is matched as soon as it lands in your account.
Does the 1 October 2026 e-invoicing obligation apply to me?
Yes, for every rental you invoice to a business. From 1 October 2026, B2B invoices must be issued through a certified e-invoicing provider. Kronn ERP includes the provider in every plan, and receipts to individuals are transmitted to myDATA as well.
How much does it cost?
Kronn ERP starts from €10 a month + VAT, billed yearly. Fleet, bookings, rental agreements and deposits are part of the industry pack, included in the Grow (€15 a month) and Scale plans.
