Short answer
In vehicle rental software, “free” almost always means a trial of 7 to 15 days, not a free plan.
Of six vendors checked on 4 October 2026, five offer only a trial, and the one page advertising “0 € per month” charges 199 € per location on top of it. A genuinely free plan exists but is always small: ours runs two vehicles, one user and ten bookings a month, and sends no email notifications at all.
On this page
We sell rental software and we have a free plan, so read this the way you would read any vendor's comparison. Every price and every trial length below comes from the vendor's own pricing page, opened on 4 October 2026 and linked at the foot of this page.
The three things "free" means on a pricing page
They are not close to equivalent, and the word on the button does not tell you which one you are looking at.
A free trial is a clock. You get the whole product for 7 to 15 days, and then you pay or you stop. Booqable is explicit about what happens at the end: your account stays inactive, you can still log in, and features are restricted until you subscribe. This is the most common meaning in this category by a wide margin.
A free plan is a set of limits instead of a clock. Fewer vehicles, fewer users, fewer bookings — but no expiry date, so you can leave it running on a quiet month and come back. This is rare in rental software.
"Free" as a headline number is the one to watch, because it is attached to a bill. One vendor below advertises a 0 € tier whose real floor is 199 € a month.
What each vendor gives you for nothing
| Vendor | Free for how long | What it costs when that ends |
|---|---|---|
| HQ Rental Software | 7-day trial, no card required | $120 / $175 / $250 a month, plus a one-time $550–$1,500, plus $50 a month per extra branch |
| Booqable | 14-day trial, no card required | From €35 a month, plus €19 for the website, €9 per user, €29 per location |
| RentSyst | 14-day version on registration | €55 a month up to 15 vehicles, then per vehicle; installation free |
| TopRentApp | 15-day trial | €119 / €169 / €399 a month, plus €9.90 per extra user, partner or office |
| Twice Commerce (was Rentle) | "0 €" platform tier | 199 € per location per month, plus 1.5% of each processed payment |
| FareHarbor | Not published | Not published — the pricing URL does not resolve to a price |
| Renviq | Free plan, no time limit | €0 for 2 vehicles, 1 user, 10 bookings a month; €49 above that |
Five of the seven rows are a countdown. That is the honest summary of this market: the sector sells trials and calls them free.
The 0 € that costs 199 €
Twice Commerce — the product that rentle.io now redirects to — deserves its own paragraph, because its pricing page is built in an order that hides the number.
You are asked to choose your inventory locations first, at 199 € per location per month. Only after that do you "pick your platform tier", and the Standard tier there is 0 €. On top of both sits a 1.5% commission on each processed payment. A one-location business therefore pays 199 € a month plus commission — currently shown as 99 € under a 50%-off promotion on the first location — and not zero.
The page is not lying. It is simply answering a different question than the one a person searching "free rental software" is asking. Read any 0 € upward on the page, never downward.
What our own free plan does not do
Ours is a real free plan: €0, no clock, no card. It is also small, and the limits are the kind you should know before you build a week around them.
- 2 vehicles, 1 user, 10 bookings a month. Above any of those you are on a paid tier.
- No email notifications at all. This is the limit people hit first and the one we would want to know about. Nothing is emailed automatically — not the booking confirmation to your customer, not a reminder to you. You send it yourself.
- 25 document scans a month instead of 250 or more on paid tiers.
Everything else is the full product, because capacity is what separates our tiers rather than features: signed rental agreements, photo inspections at pickup and return, invoicing, and a booking page of your own.
Two vehicles is a genuine evaluation, not a demo. It is not a business.
When a spreadsheet is still the right free answer
If you run two or three vehicles yourself and you have never had a damage argument, a spreadsheet is free, it already works, and switching costs you a weekend. We will not pretend otherwise — we wrote the spreadsheet comparison and it says the same thing.
The spreadsheet stops being free on the day a customer says the scratch was already there. At that point you need three things it does not hold: an agreement the renter signed, photographs of the vehicle dated at pickup, and a record of who changed which figure and when. Without them the argument is decided by whoever is more stubborn, and a single contested bumper costs more than a year of any plan on this page.
What free actually costs you
The price of a free tool is rarely money. It is these, roughly in the order operators meet them:
- The clock, if it is a trial. Seven days is not an evaluation, it is a demo you run yourself. You will not have tested a return, a damage, or a month-end in that time.
- The data you cannot take with you. Ask before you start, not after: can you export your customers, your bookings and your documents, and in what format?
- The case you cannot win. See the paragraph above. This is the only one that has a number attached, and the number is large.
How to not waste a seven-day trial
Have these ready before you start the clock, because a trial begun unprepared spends half its life on data entry:
- your vehicles with plates or hull numbers,
- your current price list, including the deposit you take,
- one real rental from last month that you can re-enter from start to finish — booking, handover, return, invoice.
That last one is the whole test. A product that looks good on a booking form and falls apart at the return is the common failure, and you only see it if you go all the way to the end.
Where a free plan exists, start there instead. There is no clock, so you can test it on a slow week and stop when you need to.
