Deposits and cancellations for mobile detailing: writing a policy that holds up

Mobile detailing has the worst no-show economics of any appointment business. A full detail is a two to four hour block. You have bought product, loaded the trailer and driven across town before you earn a cent. When the customer is not home, you do not just lose the slot — you have already spent money to be standing in their driveway.

So every guide on the subject says the same thing: take a deposit. That advice is right.

What almost none of them mention is that the term you write can itself be challenged, and the rules changed more recently than most policies on detailers' websites.

This is general information, not legal advice. Cancellation terms depend on how you contract and who your customers are. Get advice on your own wording.

What changed

Australia's unfair contract terms regime was expanded on 9 November 2023. Under the current rules it is illegal to propose, use or rely on an unfair term in a standard form contract — and the penalties attached to that are not small-business-sized.

A "standard form contract" is the ordinary case for a detailer: terms you wrote once, presented to every customer, that nobody negotiates. The booking terms on your website are a standard form contract. So are the conditions in your confirmation email.

The ACCC's own guidance is on its Contracts page.

Where detailing policies tend to get it wrong

The common pattern looks like this:

Deposits are non-refundable. Cancellations within 48 hours are charged the full service price.

Two things make that risky.

It does not flex with notice. The same penalty applies whether the customer cancels two days out, when you could still fill the slot, or shuts the door in your face after you have driven an hour. One of those is a genuine loss. The other may not be.

It may exceed your actual loss. A term that charges the full price of a service you never performed, and never incurred most of the cost of, is harder to defend than one that recovers what the cancellation really cost you.

Australian legal commentary aimed at mobile detailers makes the same point: the safer approach is to separate the scenarios rather than apply one blanket figure.

What a defensible policy tends to look like

Not a template — the shape.

Tiered by notice. More than 48 hours, deposit returned. Inside 24 hours, deposit retained. Non-attendance on the day, a stated fee. Each step reflects a different amount of loss.

Tied to real costs. Travel already undertaken, product already opened, a block you could no longer fill. A term that names what it is recovering reads very differently from one that just takes the lot.

Stated before payment, not after. A condition the customer meets for the first time in the cancellation email is the weakest version of itself. It should be on the booking form, where they agree to it.

Written in plain words. Not because plain English is a legal requirement in itself, but because a term nobody could reasonably understand when they agreed to it is a harder term to enforce.

The practical setup

Whatever you decide the policy says, the part that makes it work is that the customer sees it at the moment they book and the deposit is actually taken then — not invoiced afterwards, which is just a second debt to chase.

In Trimsy that lives in Settings ▸ Booking: deposit rules, lead time, cancellation policy and buffers in one place. The deposit is taken through Stripe or Square at the time of booking, the policy sits on the booking form where it has to be agreed to, and the confirmation and reminders carry it too, so nobody can say they never saw it.

The buffer setting matters more than it looks for mobile work. It is how travel gets into your calendar without being invisible — the gap after each job belongs to the drive, so your third booking of the day is not already late when you accept it.

What Trimsy will not do is plan your route. There is no optimiser that orders tomorrow's jobs to cut your driving. If that is your main problem, a dedicated field service tool is the honest answer.

The part that is not about rules

A well-written cancellation term protects you perhaps a handful of times a year. Reminders prevent the cancellation in the first place, which is worth more.

An automatic reminder three days out and again on the morning catches the customer who genuinely forgot — the largest group by far. The policy is for the ones who did not forget. Most businesses get this backwards and spend a fortnight on the wording while sending no reminders at all.

In short

Take the deposit. Write the term so it steps with notice and recovers something you actually lost. Put it in front of the customer before they pay, not after they cancel.

And get it checked. A clause copied from another detailer's site is a clause nobody has read against the current rules — including the person you copied it from.
