Two rental platforms can advertise almost the same monthly figure and still be thousands of euros apart after a year. The gap rarely comes from the headline price: it comes from what sits behind it — a percentage taken off every booking, a setup fee billed once, modules charged separately, a per-seat cost that climbs with the team. This guide takes apart the pricing models on the market in 2026, the levers that move the price, and the charges that only surface on the twelfth invoice, so you can compare offers on the number that actually matters: what you will have paid at the end of the year.
The three pricing models you'll run into
A flat monthly subscription
This is the most common model and the easiest to read: the same amount every month, usually split into tiers by feature set. Its strength is predictability — your software bill is identical whether you sign three rental agreements this month or thirty, and as the business grows the software line shrinks as a share of your costs. What deserves a close look: how long you are tied in, the fleet-size thresholds that bump you into the next tier, and which features are locked behind the top plan.
A commission on every booking
Some vendors take a percentage of each booking made through the software, or through the booking site they supply. It sounds good at first — nothing fixed to pay, you only hand over money once money comes in — but it works against you the moment volume picks up: the better the year, the bigger the bill, and often with no ceiling. On a premium fleet, where a single rental can run into four figures, even a modest percentage adds up to far more over twelve months than a flat subscription. Model it against your own bookings before you sign; it is the most expensive assumption on the table.
Setup, onboarding and licence fees
The third component is the one-off charge: installation, configuration, onboarding. It pays for the initial setup, importing your fleet and your rates, and sometimes training. Billed once, it can weigh heavily on the first year. Some vendors will waive it if you ask — so ask, and ask what it actually buys you: migrating your data, rebuilding your contracts and documents in your own wording, time with your team.
What pushes the price up
The size of the fleet
Most price lists are keyed to the number of vehicles you manage. Two figures matter: what one extra vehicle costs, and the threshold that tips you into the next plan up. That threshold is where the unpleasant surprises live, and it tends to arrive exactly when the fleet is growing and you need the tool to keep up rather than bill you more.
The modules you switch on
Scheduling, dynamic pricing, digital condition reports, invoicing, review collection: every module has a price. There are two approaches — everything bundled into a plan, or à la carte billing. À la carte looks cheaper at first glance, but once you add the modules a rental operator genuinely cannot work without, the total often lands above an all-in plan. Compare like for like, on the same feature set, or you are not really comparing anything.
White label and the booking site
A booking site under your own name and colours, with no redirect to a marketplace, matters far more to a premium operator than to a budget one: it protects the brand and keeps the customer relationship yours. Some vendors treat it as an expensive extra, others fold it into their plans. Check as well that no commission applies to bookings taken on your own site — paying commission on bookings you brought in yourself is a bad deal.
The hidden costs to dig out before you sign
The advertised price is only the visible part. These are the lines that quietly inflate the bill:
- Integrations: payment, accounting, electronic signature: sometimes billed per connector, sometimes reserved for the higher plans.
- Training: is the first session included, and what does another one cost when you hire?
- Support: email support included, phone access or a named contact charged on top.
- Data migration: bringing over your customer history and your past agreements is not free everywhere; ask.
- Extra users: a per-seat price that climbs with the team and with every branch you open.
- Local invoicing rules: they differ by country. In France, check what the NF525 framework requires of your invoicing software before you commit; other markets set their own rules. Ask what the vendor covers where you operate, and whether it costs extra.
- Getting your data out: exporting everything when the contract ends is a contractual and GDPR question. Settle it before you sign, not after.
How to compare offers properly
The only reliable method is to work out the total cost over twelve months, using your real volumes, rather than lining up entry prices:
- List the features your business cannot run without, then the ones that are merely comfortable to have.
- Ask for a written all-in quote: subscription, add-ons, setup, training, support.
- Model the commission option against your actual and projected revenue, not a round number.
- Check the commitment period, the notice you have to give and how you get your data back.
- Test how quickly support answers during the trial or the demo — it is your best sample of what year two will feel like.
The comparison that counts is not the advertised price but what you will have paid by the twelfth month, subscription, add-ons, commissions and one-off fees included. Our car rental software comparison sets the published prices of several vendors side by side.
Where Corsiva OS sits
Corsiva OS keeps it simple: a flat monthly subscription, with no commission on your bookings. Three plans — Lite at €59/month, Business at €98/month and Ultra at €199/month, excluding VAT, on a one-year commitment (−16%). Without commitment, the same plans are €70, €117 and €237. There is no setup fee on the subscription itself. Prices are indicative.
Add-ons are priced in the open and switched on only when you need them: online payments at €15/month, automatic emails at €5/month and the Fleet desk module (owner accounts, statements and revenue sharing) at €19/month on a Lite plan; all three are already part of Business. White label is €29/month, included with Ultra; a booking site connected to the software runs at €39/month plus a one-off €400 setup. The platform covers the job end to end: bookings, scheduling, digital condition reports, rental agreements, invoicing and owner statements, with servers and database in Europe and built-in GDPR tools. Every plan and every option is laid out on the Corsiva OS pricing page, with a builder that totals your own configuration as you tick the boxes.
The bottom line
A rental platform is not judged on its entry price but on what it costs to run: the pricing model, the feature set, the extras and the exit terms. A flat, transparent subscription makes that arithmetic simple; a commission model demands serious modelling before you commit to anything.
