Kronn Smart 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 Smart 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.

Built for your line of work

The industry pack is included in Grow and Scale.

01

Vehicle fleet

Every vehicle with plate, category and mileage, plus reminders for servicing, roadworthiness tests (KTEO) and insurance renewal.

02

Bookings and availability

A calendar per vehicle and category: see instantly what is free for the dates the customer wants, and avoid double bookings.

03

Rental agreements as PDF

The agreement carries your logo and the driver’s details, dates and pick-up and return locations, mileage and fuel.

04

Daily and seasonal rates

Rates per category, day and season, plus extras such as a child seat, an additional driver or extra cover.

05

Deposits

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

06

Mileage and damage

Check-out and check-in notes for mileage, fuel and damage; extra charges go straight onto the final document.

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 mandatory e-invoicing apply to my rental business?

Yes, for every rental you invoice to a business. For businesses with revenue up to €1M, B2B invoices are issued electronically from 2 November 2026 and, from 1 February 2027, only through a certified e-invoicing provider. Kronn Smart includes the provider in every plan, and receipts to individuals are transmitted to myDATA as well.

How much does it cost?

Kronn Smart 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.
