The deposit that protects a full-day bay
A haircut lost to a no-show costs an hour. A ceramic coating lost to a no-show costs a bay, a detailer and a day — and on a Saturday in April, a day you could have sold three times.

Detailing studios learn this the expensive way, usually more than once. The cure is not a stern message; it is three settings that make a long job hard to abandon and easy to keep.
Make the bay a thing you book
Add each bay as a resource, and link each service to the bays it can use. A coating then takes a bay and a detailer together, for as long as the job takes — up to a full day. Nothing else can be booked into that bay while the job holds it, and nothing is offered at an hour when no bay is free.
A booking lasts up to 24 hours. A job that runs longer — a full wrap with a cure overnight — is booked as two visits, one after the other, in the same bay.
Size the deposit to the job, not the price list
A flat percentage across every service protects the long jobs too little and puts off the short ones. Set the deposit per service instead:
- Nothing on an express wash or an interior refresh — these are how new clients try you.
- A real deposit on a coating, a film or a paint correction — enough that a client thinks before abandoning the day.
- The full price at booking for the jobs where you buy the material in advance, if you prefer.
The deposit is taken at booking on your own payment gateway, so the money is yours, not a platform’s, and it is kept if the client cancels inside your notice window.
The question is not how much the job costs. It is how replaceable the day is. A Saturday coating in April is not.
Set a notice window you can actually refill
Twenty-four hours is the convention. For a full-day job it is usually too short: a client who cancels on Friday afternoon leaves you a Saturday nobody will book at that notice. Two or three days is fair for a coating, as long as you say so before the client pays, not after they cancel. The window is one setting for the whole studio, and it decides by itself whether a deposit is kept — and since an express wash carries no deposit, a longer window costs the short jobs nothing.
Photograph the car when it arrives
Before and after photos are attached to the visit, so a question about a mark on the paint a week later is settled from the record, not from memory.
And bring them back
The best protection against an empty bay is a client who comes back on schedule. Set a return interval on the coating, and the next maintenance visit is offered at checkout, when the client is standing in front of a car that looks its best. The next post in this series is about exactly that.
