A workshop sells bay hours to cars that come to it. A mobile mechanic sells the same skill with travel attached, from a van carrying whatever was loaded that morning, to a customer whose driveway may or may not be somewhere the job can actually be done. Almost every difference that matters comes back to one of those three things.
Booking by location as well as by registration
A garage booking needs a date, a time and a registration. A mobile booking needs an address before any of that is worth confirming, because a job forty minutes outside your area is a job you should be pricing differently or declining.
Capture the postcode early in the booking, before the customer has invested five screens of effort, and be explicit about the area you cover. A customer who finds out at the end that you do not come to them is a wasted enquiry and an irritated person.
The registration still matters as much as it does in a workshop. It identifies the vehicle, it brings the MOT history and it is how you find the job again next year. What changes is that it is now the second question rather than the first.
Ask the questions the driveway raises at booking. Is it on a driveway or on the street. Is there room to work at the side of the car. Is it a permit or red route area. Is there a slope. Ten seconds of form beats a wasted thirty minute drive, and none of it is a question a workshop ever has to ask.
Planning a round
Travel is unpaid time and it is the largest controllable cost in a mobile business. Four jobs booked by the order the calls came in can easily carry two hours of driving. The same four planned by area carry twenty minutes.
The practical method is not clever software, it is geography and honesty about time. Give each day a rough area, hold the bookings for that area together and keep one flexible slot for the job that overruns, because one of them will.
Book windows, not times. Between nine and eleven is a promise you can keep. Nine fifteen is a promise the M25 will break for you, and the customer who took a morning off work will remember which of those two you gave them.
Count travel in the price rather than pretending it does not exist. Whether that is a call out charge, a wider area rate or simply a higher labour rate than a workshop charges is a commercial decision. Leaving it out entirely means your longest days are your least profitable ones and you will not be able to see why.
Quote before you travel
A wasted journey is worse for you than for the customer. The fix is a quote sent and accepted before the van moves, with the assumptions written on it: what is included, what is not, what happens if the fault turns out to be something else and what the diagnostic charge is if the answer is that the job is not viable on a driveway.
Be plain about the jobs you will not do at the roadside. Anything needing the car properly in the air, anything requiring a press, a lift or containment of fluids and anything that cannot safely be finished before dark in winter. Saying so on the quote is better than discovering it kneeling on somebody wet gravel.
Get the acceptance timestamped rather than agreed on the phone. A quote the customer taps to approve records exactly which lines were accepted, which matters more for a mobile job than a workshop one because there is no counter, no paperwork handed over and nobody else present.
Photograph the vehicle when you arrive and again when you finish. There is no workshop CCTV and no body shop inspection sheet, and a pre existing scratch on a driveway is a much easier conversation with a timestamped photo than without one.
The van is your parts department
You cannot walk to the rack. Every job is either done with what you loaded this morning or it is a second visit, and second visits are the thing that quietly destroys a mobile mechanic margin.
That makes the booking conversation do more work than in a workshop. Knowing the registration, the symptom and ideally a photograph before the day starts is what lets you load correctly, and a service kit for a known vehicle is a very different load from a diagnostic on a fault described as a noise.
Carry consumables deep and specific parts thin. Oil, filters, bulbs, wiper blades, brake fluid, fixings and the common service items earn their space. A speculative alternator does not, and a trade counter that delivers to a postcode within the hour is a better use of the same money.
Keep a supplier relationship that works from the roadside, and price the collection into the job when it happens. Purchase orders raised against the supplier while you are standing at the car are how the cost stays attached to the job instead of turning up on a statement at month end.
Getting paid on the driveway
Payment on completion is the whole game. A mobile job invoiced afterwards is chased more often than a workshop job, because you have already handed back the keys and driven away, and there is no car on your premises giving the customer a reason to settle.
Take the card before you pack up. Tap to Pay on iPhone accepts a contactless card or phone against the back of a recent iPhone with no reader to carry or charge. For the customer who wants to pay another way, send the payment link there and then while you are both standing next to the car.
Deposits do more work in a mobile business than anywhere else, because your cost of a no show includes the drive. A deposit at booking on anything longer than an hour is normal and customers accept it readily when the reason is explained.
For account work from dealers, lease companies or fleets, agree the terms and the purchase order process before the first job rather than after the first unpaid invoice. Fleet work is good work and it is billed on somebody else timetable.
No premises changes the paperwork
Your invoice still needs a business address, and for a sole trader working from home that is a decision worth making deliberately. Check what your insurer, your mortgage or tenancy and your local authority expect, and take advice rather than assuming nobody minds.
Waste follows you home if you let it. Used oil, filters, coolant and old parts are controlled waste and they need a licensed route, whatever the size of the operation. It is a real cost and it belongs on the invoice as a named line rather than absorbed.
Check what your insurance actually covers. Working on a customer vehicle on a public road, on a private driveway and on a business premises are not always the same thing to an insurer, and road risk for a vehicle you are moving is separate again.
