Boat rental software: the comparison

Software for boat rental companies differs less on the planner, which they all offer, than on what happens at the dock and after the return: security deposit by card pre-authorisation, photo inspection, comparison of the return against the departure, return charges, maintenance and managing boats on behalf of owners. The table below compares five software products on the same criteria, based on what each vendor publishes.

How to read this table

At the office, they all keep a planner; the differences lie in quotes accepted online and booking from the rental company’s website.
At the dock, look at the security deposit by card pre-authorisation, the photo inspection on a phone and the comparison of the return against the departure: that is where disputes are decided.
After the return, recharging fuel, breakage and missing items, then maintenance.
If you manage boats for owners, check that the owners have their own access and that owner payouts are calculated automatically.
On price, tell the fixed subscription apart from any commission on online bookings.
