Ask ten mobile detailers how many jobs they do in a day and you'll get answers from two to six. Ask them what time they got home and the range narrows considerably.
The number that matters isn't how many jobs you can fit. It's how many you can fit and still finish before dark, without the last customer getting a rushed car, and without you doing paperwork at eleven at night.
The hour you never budget for
Take a standard full detail you'd quote at three hours. Here's the actual day for that job:
| Minutes | |
|---|---|
| Drive to site | 25 |
| Setup — hoses, power, water, gear out | 15 |
| The work you quoted | 180 |
| Pack down | 15 |
| Payment, notes, photos | 10 |
| Buffer (customer chat, the thing you didn't see) | 20 |
That's 265 minutes — 4 hours 25 minutes for a "three hour" job. Not because you're slow. Because a mobile job is a three-hour job plus 85 minutes of being mobile.
Run that against a nine-hour working day and you get two of those, comfortably, with about twenty minutes spare. Not three.
Why the third job breaks
The third job is where the maths turns hostile, for three compounding reasons.
Drive time isn't linear. Job one is near home. Job two is chosen to be near job one. Job three is wherever the booking came from, which is usually the other side of the service area at exactly the wrong time of day. That 25-minute average becomes 45.
Fatigue is real and it costs minutes. A three-hour detail done at 8am takes three hours. The same detail at 4pm takes three hours and twenty minutes, and the quality gap is visible.
The buffer disappears. By job three you've already spent your slack on the first two. Any surprise — pet hair, a heavier interior than described, a customer who isn't home — comes out of your evening, not out of a buffer.
So three full details a day is possible. It's just a ten-and-a-half-hour day with no margin, and the third car is your worst work.
What actually stacks
The shops running four or five stops a day aren't doing four full details. They're mixing job types, deliberately.
- A full detail (3h) plus two maintenance washes (45m each) is a genuinely comfortable day. Roughly 7 hours 20 including drive and setup.
- Four maintenance details (90m each) in a tight radius works if — and only if — the radius is tight. Same-neighbourhood clustering turns 25-minute drives into 8-minute drives and buys you a whole job.
- One large job (5-6h) and one small one is the safest shape for a day that includes anything unpredictable.
The pattern is: one anchor job that pays for the day, then smaller work that fits around it.
Cluster geographically, not chronologically
The single highest-leverage change most mobile operators can make is to stop booking by "next available slot" and start booking by area.
Assign days to zones. West side Tuesday and Thursday, east side Wednesday and Friday. When someone calls for the west side, they're offered Tuesday or Thursday. Some will push back; most won't, because they don't care which day, they care that you show up.
Done properly this takes 30–40% off your daily drive time, which is very close to a free extra job.
The objection is always "I'll lose bookings by not being flexible". In practice you lose a handful of impatient customers and gain an hour a day, five days a week. That's 20 hours a month — more than a full working week — recovered from your van.
Water, power and the constraint nobody plans for
Two practical ceilings that cap your day regardless of scheduling:
Water. A 100-gallon tank does roughly two to three full details depending on how careful you are. If your third job needs a refill, that's 20–30 minutes plus the detour. Know your real consumption per job type; most people overestimate their capacity by one full job.
Power. Running an extractor, a polisher and a vacuum off a generator or an inverter has a duty cycle. If you're doing three interior-heavy jobs in a row, your equipment may well be the thing that decides your day, not you.
The realistic answer
For a single-operator mobile detailer in a Canadian city, working a nine-hour day, honestly:
- Two full details — comfortable, sustainable, high quality, roughly 7.5 hours.
- Three full details — possible, tiring, quality drops on the third, 10+ hours.
- One full detail plus two maintenance jobs — the best revenue-per-hour shape most operators find.
- Four-plus — only with tight geographic clustering and mostly maintenance work.
Anyone claiming five full details a day, solo, is either counting differently or not sleeping.
Book against real availability, not optimism
The scheduling failure that costs the most isn't overbooking a day — it's overbooking a person. A second van doesn't double your capacity if both techs get booked into the same three-hour window on opposite sides of town.
Whatever you schedule with needs to hold two things: each person's actual working hours, and the jobs already sitting in them. If you're promising slots from memory, you will eventually promise the same Tuesday afternoon twice, and you'll find out about it on Tuesday afternoon.
Concorso's schedule lays the week out against each person's availability for exactly this reason — mobile work is time-blocked rather than queued, and the whole point of a calendar is to see the conflict while you're making it.
The number worth tracking
Forget jobs per day. Track revenue per working hour, including drive time.
A day with two jobs at $350 each over 7.5 hours is $93/hour. A day with three jobs at $350 over 10.5 hours is $100/hour — seven dollars better, for three more hours of your life and a worse third car.
Once you're measuring that, the scheduling decisions make themselves.
