CMMS for vehicle rental companies

Vehicle rental adds a difficulty to fleet maintenance that an owned fleet doesn’t have: the asset passes through many hands. Between two rentals you need to know what condition it comes back in, who caused what, and whether the vehicle can go out again. And all of that with the unit off the road for as little time as possible, because a vehicle in the shop doesn’t bring in revenue.

The vehicle as an asset, with its counter

Each unit gets its own record in asset management: plate number, model, chassis number, registration date, acquisition cost, warranty end date and location.

What matters here is the counter: mileage or hours. It’s logged as a reading, with who took it and when, and it’s the basis for everything else. Each vehicle also supports custom fields with their own unit — payload, fuel type, rental category, number of seats — because what describes a passenger car doesn’t describe a refrigerated van.

Inspections that follow usage, not the calendar

This is where a rental fleet differs from almost everything else: two identical units bought on the same day can rack up 8,000 and 60,000 kilometers.

A limit is defined against the counter — the mileage that maintenance task or component is expected to last — along with a warning percentage. When someone logs a reading, the system adds up the accumulated total, calculates the percentage used and, if the threshold is exceeded, generates the preventive work order automatically, with its vehicle and the matching checklist.

It’s worth combining this with time-based scheduling, because they cover different things: time-based covers what degrades whether or not the vehicle is on the road — oils, batteries, mandatory inspection; counter-based covers what wears out through use. A single vehicle can carry several schedules at once.

Condition between rentals

The pickup and return inspection is where money is made or lost, and where paper works worst.

A checklist with its fields, mandatory photos and values — fuel level, mileage, tire condition, damage — leaves an exact record of the situation with date, author and signature. And fields with a minimum and maximum turn an out-of-range reading into an anomaly logged on the spot, not a note on the side.

The checklist is defined once per vehicle family and resolves in cascade — unit, model, subfamily, family — so it isn’t configured car by car.

When damage shows up, it turns into an incident with its priority and owner, and from there into a work order. With a photo and the customer’s signature captured on the spot, the later argument over who caused it stops being an argument.

Documentation that expires, and that grounds the vehicle

In rental this isn’t administrative: it determines whether the vehicle can go out. Insurance, roadworthiness inspection, permits, registration document, authorizations.

The document manager attaches documents to the vehicle, the client or the work order, decides who sees them and gives them an expiry date, with a daily check on what’s about to expire and its corresponding notification.

Loading in those dates is half an afternoon of work and it’s probably the part that pays for itself fastest: the cost of finding out too late isn’t a repair, it’s a grounded unit and, depending on the case, a fine.

When to stop repairing a unit

The business question of the sector, and the one that’s almost always answered by gut feeling.

Each vehicle can have its replacement cost logged, along with a warning percentage. The system compares the accumulated cost of its repairs against that amount and warns when it’s exceeded. It doesn’t generate an order — renewing a unit is a business decision, not a task — but it puts the figure in front of you right when it needs looking at.

Alongside that, the reports give accumulated cost per asset, downtime, MTBF and MTTR, and materials consumed. A vehicle that has cost three times as much as its twins has an explanation, and it’s usually in how it’s used, not in the mechanics.

In-house shop and outside shop

Part of the work is done by the in-house shop and part by an approved outside one. Both have to be logged the same way, or the history will have gaps right at the most expensive jobs.

Providers are registered and receive the work orders assigned to them, with their times, materials and documentation. Since licenses are unlimited across all three plans, registering every workshop isn’t a financial decision.

If the work is in-house, the mechanic logs it from the app: a timer on the order, consumption against the warehouse — with the original part reference on hand, which in automotive is what lets you find the equivalent when the original part is weeks out — checklist, photos and signature. It works without a connection.

Letting the customer see it

In long-term rental and leasing, a large share of the calls don’t ask for anything: they ask when the inspection is due or how the repair is going.

With their own dedicated access the customer opens incidents with a photo, tracks the status of their orders, downloads reports and sees the upcoming preventive maintenance for the units assigned to them, letting them plan the vehicle handover without anyone having to call them.

Two honest caveats: the customer can’t change the status of an order — it’s disabled on purpose — and their app doesn’t work offline; full offline mode belongs to the technician app.

Availability as the metric

In rental, the metric that matters isn’t maintenance cost: it’s how many days each unit has been unavailable for rental. A cheap workshop that grounds the vehicle for five days ends up costing more than a pricier one that returns it in one.

That’s measured with the order’s timings, which store the target time, the estimated time and the deviation between what was planned and what actually happened. Comparing by workshop and by type of job surfaces information that’s rarely organized: who meets deadlines and who doesn’t, and on which type of repair.

It’s also what makes it possible to schedule inspections where they hurt least. If the system warns when the mileage threshold is reached instead of when the fault appears, the downtime can be fit between two rentals instead of canceling one.

Where to start

With two things, in this order. The expiring dates — insurance, inspections, permits — loaded with their expiry, which is the cheapest step and the one that removes the most risk. And the pickup and return checklist, which is where money is lost every single day.

Mileage-based inspections and old history come next.
