How to Invoice Mobile Car Detailing Packages: Express, Full Detail, Paint Correction

Mobile car detailing businesses run on packages. An express wash, a full detail, and a paint correction are three completely different jobs at three completely different price points — and they need to be invoiced differently to avoid client confusion, underbilling, and payment disputes.

This guide shows how to invoice each package type correctly, including add-ons, vehicle size adjustments, and multi-day premium jobs.

Express detail invoicing

An express detail is typically a wash, vacuum, and window clean. It is your highest-volume, lowest-price service. Invoice format:

Express detail — wash, vacuum, windows. Sedan rate.

Keep it simple. If the client adds a tyre shine or interior wipe-down, add them as a line item:

Add-on — tyre shine + dressing.

Express detail invoices should be sent immediately after the job. With SMASH, describe the job in 10 seconds and send it while the client is inspecting the car.

Full detail invoicing

A full detail includes exterior wash, interior deep clean, vacuuming, leather or fabric conditioning, windows, and protection. Invoice format:

Full detail — exterior wash, interior deep clean, vacuum, leather condition, window clean. Sedan rate.

If specific add-ons are included in your full detail package, either include them in the package name or list them separately. Listing them separately makes the invoice feel more thorough and justifies the premium price.

Paint correction invoicing

Paint correction is your most complex, highest-value service. It typically spans one to two days and involves machine polishing, panel inspection, and ceramic or wax protection. Invoice format:

Paint correction — full correction (2-stage), 1.5 days labour. BMW M3.

Ceramic coating — Gyeon Quartz One, applied to all exterior panels.

PPF — front bumper and bonnet (if applicable).

For multi-day paint correction jobs, you can invoice at completion or issue a deposit invoice:

Deposit — 50% of total quoted price for paint correction and ceramic coat.

Final balance — remaining 50% on completion.

Include photos of the completed work in the email you send with the SMASH invoice. This supports the value of the service and reduces disputes.

Add-on pricing

Add-ons should always appear as separate line items, not bundled into the package price:

Add-on — clay bar treatment.

Add-on — engine bay clean.

Add-on — odour bomb treatment.

Add-on — ceramic coating top-up.

Separate add-on lines show the client exactly what they are paying for and make upselling transparent. If a client declines the add-on next time, they know exactly what they will lose.

How to invoice multiple cars in a day

For six cars on a Saturday:

1. Invoice immediately after each car using SMASH.
2. The client receives the invoice and payment link on their phone.
3. They pay by card before you move to the next vehicle.
4. By the end of the day, all six are paid. No catching up on Sunday.

Each invoice takes under 60 seconds from a voice description. Batching invoices at the end of the day risks forgetting details on early jobs and delays payment.

Frequently asked questions:

Can I set different package prices? Yes. Store express, standard, full detail, and paint correction packages in SMASH with vehicle size variants.

How do I invoice a multi-day paint correction? Use a deposit invoice on day one and a final balance invoice on completion. Both generated from voice descriptions.

Should add-ons be listed separately? Yes. Separate add-on lines make the invoice clearer and support upselling in future visits.

Can clients pay between cars? Yes. Send the invoice immediately after each job with a payment link. Clients pay by card before you start the next vehicle.
