In many Latin American cities the taxi isn't driven by the person who bought it. The car owner, sometimes with two or three vehicles, hands it to a driver in exchange for a daily or weekly "fee", and whatever the driver earns above that fee is theirs. It's an arrangement as old as the trade, and also one of the most common sources of conflict: fees that can't be met, cars that break down, drivers who vanish and owners who don't know how much their vehicle actually works.
The thesis of this article is that the owner-driver arrangement works much better when it's written down, when the fee is calculated with real numbers and when both see the same information about the car's work. A ride app doesn't replace that arrangement, but it can remove a good part of the suspicion. We'll look at how to set a fair fee, what the agreement should say, how to split costs and how to resolve the most frequent disagreements.
How the fee works and why it causes conflict
In its simplest form, the driver pays the owner a fixed amount per day or per week and keeps everything else. The owner covers the cost of the car, the insurance and a good part of the maintenance; the driver contributes their time, their work and, usually, the fuel. On paper it's a clear split, but in practice each of those pieces leads to arguments.
The conflicts that repeat most between owners and drivers tend to be these:
- The fee is so high that on slow days the driver can't meet it.
- It isn't clear who pays for a tyre, a dent or a fine.
- The car spends days in the garage and nobody knows if the fee applies.
- The owner suspects the driver works more than they report.
- The driver uses the car for personal purposes outside the shift.
- Nothing is written and each remembers the deal differently.
Almost all these conflicts share the same root: a lack of shared information and the lack of a written agreement. When the owner can't see how much the car works and the driver doesn't clearly know what they're responsible for paying, any setback turns into an argument.
How to set a fair fee
A fair fee isn't taken from what other owners charge or from what the owner needs to pay off the car loan. It's calculated from what the car can really produce on a normal day. If the fee eats up almost everything the driver earns on an average day, the arrangement won't last: the driver will work endless shifts, neglect the car or leave at the first opportunity.
The simplest way to calculate it is to look at real income over several weeks, subtract fuel and the costs the driver covers, and split what remains so both earn. If the car works with an app, the trip history gives exactly those numbers: how many trips it makes, at what times and how much it bills. Without data, the fee is set by guesswork and one of the two ends up losing.
It's also worth thinking about slow days. Some arrangements use a lower fee on weekdays and a higher one at weekends, or a weekly fee instead of a daily one so the good days make up for the bad ones. What matters is that the fee reflects how demand really moves in the city.
What the written agreement should say
An owner-driver agreement doesn't need to be a complicated contract. One or two pages, signed by both, that answer the questions that cause most arguments are enough. It's worth including, at a minimum, the fee amount and when it's paid; who pays for fuel, maintenance, tyres and repairs; what happens if the car is in the garage; who is responsible for fines and dents; at what times the car can be used and whether it can be used outside work; and how much notice either can give to end the arrangement.
Labour and transport rules change by country and city, so it's worth checking with a local adviser what kind of arrangement is valid and what obligations each party has. What holds everywhere is that a written agreement, however simple, protects both far more than a verbal one.
Splitting the costs
Maintenance is where most arrangements break. If the driver feels every cost falls on them, they'll postpone oil changes and checks; if the owner feels the driver mistreats the car, they'll distrust every repair. A clear rule helps a lot: normal wear on the car, such as servicing, tyres worn through use or brakes, is covered by the owner; damage through carelessness, such as a dent or a fine, is covered by whoever caused it.
It's also worth agreeing on a preventive maintenance schedule by kilometres or by dates. A car that is serviced on time spends fewer days off the road, and every day off the road is a day without a fee for the owner and without income for the driver. Seen that way, preventive maintenance is an investment that suits both.
I had three cars and argued every week with all three drivers about the fee. We started reviewing together what each car did in the app and adjusted the fee to reality, lower on weekdays and higher at weekends. Since then we hardly argue and the drivers look after the cars better.
Shared information: what an app changes
One of the biggest sources of suspicion between owner and driver is not knowing how much the car really works. When trips arrive through an app, there's a record of each one: the time, the distance and the amount. If owner and driver can see that information, the conversation stops being about what each believes and becomes about what really happened.
That same information helps adjust the fee over time, see whether the car spends too many hours parked or whether it should work at other times, and lets the driver show they had a bad week because of low demand rather than lack of effort. Transparency isn't monitoring the driver: it's giving both the same basis to negotiate.
And if the owner has several cars, reviewing the numbers for all of them together helps see which performs best and why, and to share out times or areas among the drivers.
When there's disagreement
Even with everything written down, there will be disagreements. The best way to handle them is to talk early, with the numbers to hand and before the problem grows. If the fee no longer adds up because demand fell in the city, it's worth reviewing it together instead of the driver getting into debt or leaving the car. If the owner thinks the car is being mistreated, it's worth checking it with the driver present and deciding what gets fixed and who pays.
When owner and driver work with a fleet, the fleet can help mediate: it has the trip information, knows both and has an interest in keeping the car working. A three-way conversation, with data, often resolves in minutes what would otherwise end in a break-up.
It's also worth thinking long term. Some owners offer drivers who have been with them a long time and look after the car well the option of paying off the vehicle little by little until they own it. It isn't for everyone, but when it works, it turns a driver into a committed partner and frees the owner to invest in another vehicle.
What to take away
The owner-driver arrangement is the foundation of many taxi fleets, and it works best when treated as what it is: a business between two parties who need each other. A fee calculated with real data, a simple written agreement, clear rules on costs and shared information about the car's work prevent most conflicts.
If your fleet runs on its own app, each car's trip history is the best tool for owners and drivers to negotiate with numbers instead of suspicion. A fair arrangement keeps good drivers, looks after the cars and lets the whole fleet work with more peace of mind.
