A rental fleet is won or lost between bookings, not on the day a contract is signed. What you actually control is how full the calendar stays, how your rate plans are built, and how cleanly you settle up with the owners whose cars you run. Fleet management software made for this trade puts those three levers on one screen, and that is where a car stops being a standing cost and starts paying for itself.
Run a fleet on a spreadsheet, a shared calendar and hand-typed invoices and it will cost you: weekends that quietly go unbooked, prices set on gut feel, owner statements that eat a full evening. Corsiva OS was built by people who do this for a living (Corsiva runs its own rental agencies in the French Alps, from its base in Chambéry) to close exactly those gaps. Here is how a serious tool helps you fill the schedule, structure your pricing and see what each vehicle is really worth, with no promises about the parts that are out of your hands.
Occupancy is the real lever
A car sitting idle over a long weekend (a prestige car even more so) is revenue you will never get back. So the first job of fleet management software is to make occupancy something you can read at a glance and act on. With bookings and fleet planning in one place, you see what is out, what is free, what is coming back from servicing and what is going out on delivery.
That visibility changes how you sell. You know which car to push, which weeks are underused, and which way to steer a client who is torn between two models. You stop selling on instinct and start filling the calendar on purpose.
- One fleet view: every vehicle, every location, every slot on a single live schedule.
- Several locations: run every branch without doing the work twice, which matters the day you open the next one.
Rate plans you control, prices that follow demand
Pricing is the second lever, and the one many rental companies leave untouched. A wedding weekend, a trade-show week, the first warm days of the season: demand is not flat, and your prices have no reason to be. The right tool lets you build clear rate plans (24 hours, weekend, week, long term) and move your rates by season, by event or by how well a given period is selling.
The point is not to charge more for the sake of it. It is to stop leaving money on the table at the peaks while staying attractive in the quiet weeks. A properly built rate card protects your margin too: included mileage, the charge per extra kilometre, the insurance excess and the extras are defined once, quoted correctly and applied without anyone mistyping a figure. Our guide to dynamic pricing for car rental shows how to set the rules. Our software comparison sets out what a purpose-built tool does that a generic one does not.
Per-vehicle tracking: what each car actually earns
Not every car in the fleet pays for itself equally. Accurate per-vehicle tracking tells you which one goes out most often, which one is due a price review, and which one costs more in downtime than it brings in. That level of detail is what lets you make a call instead of a guess: back the model clients keep asking for, retire the one that disappoints, take on a new vehicle knowing what it has to earn.
By pulling bookings, payments and condition reports together under each vehicle, the software gives you a clean read on what each car actually brings in: the basis for running a fleet on numbers rather than impressions. The same file holds the photos and reports your insurer will ask for after a claim; our guide to car rental fleet insurance explains what to keep.
Owner-managed fleets: the 70/30 payout, automated and transparent
If you rent out cars entrusted to you by their owners, the owner payout is usually the slowest and touchiest job on your desk. The Corsiva OS Fleet desk module works out the split according to your agreement (a 70/30 revenue share, for instance) and gives each owner a clear statement of what their vehicle earned over the period.
That transparency sells. An owner who can see their rentals, their revenue and their statement without having to ask is an owner who hands you a second car. You save the accounting hours and you build the trust that grows the fleet.
- Owner accounts: statements produced automatically, the split configured to your agreement, a summary they can read at the end of every month.
- Invoicing in the same flow: invoices numbered in sequence come out of the rental record instead of a separate app, with nothing re-keyed. Invoicing rules differ from one country to the next: in France, check what the NF525 framework requires of your invoicing software before you commit, and ask the same question wherever else you invoice.
Payment, security deposit and delivery without friction
Getting more out of a vehicle also depends on how smoothly the day runs. Corsiva OS takes payment through Stripe, holds the security deposit as a card hold and collects the pre-payment automatically: the client pays online, the deposit is held without the card being charged, and the rental is covered before the keys change hands. At the handover itself, mobile condition reports with e-signature record the state of the car at departure and on return, dated and hard to argue with, which is what you need when you have to charge damage and the excess to the renter.
Delivery and collection, plus a chauffeur service, let you move upmarket and charge for the level of service your clients already expect. That is billable work, not just a courtesy. White label, servers and database in Europe and built-in GDPR tools finish the picture: the experience carries your name from the quote to the invoice.
From independent agencies to premium fleets, sized to your operation
No two rental companies need the same thing, and a tool should not charge you for what you never open. Corsiva OS comes in three plans, from the independent operator getting a first fleet organised to the multi-site company running a premium fleet:
- Lite — €59/month · Business — €98/month · Ultra — €199/month, excluding VAT on a one-year commitment (a 16% saving). Month to month, the same plans are €70, €117 and €237. Indicative pricing, subject to change.
- Options you add only when you need them: white label at €29/month, a booking site at €39/month plus a €400 setup fee.
The right plan is the one that matches the size of your fleet, the number of locations you run and the services you sell. Every plan and what it includes is laid out on the Corsiva OS pricing page, and our team can help you work out which one fits your fleet.
In summary
Getting more out of a rental fleet is not a trick. It is a routine, backed by the right tools: fill the schedule, price with intent, watch every vehicle and hand your owners accounts they can trust. Fleet management software written by people who run this business gives you those levers; the decisions stay yours. To see how Corsiva OS fits the way you work, get in touch.
