Invoicing App for Auto Detailing: Packages, Add-ons, Deposits and Fleet Bills

An auto detailing invoice app turns each job into a numbered invoice with the package, add-ons, tax and any deposit already paid. Describe how you bill paint correction, ceramic coating and washes, and Mythex builds the app with PDF invoices and an unpaid list on a real database.

Who it's for

Mobile and unit-based detailers who write invoices in a notes app or a spreadsheet, take coating deposits by bank transfer and lose track of them, or bill dealerships and fleets for many cars at once.

What you can build

Package lines priced by small car, SUV or van
Add-ons such as pet hair removal, engine bay or glass coating
A deposit invoice when a coating job is booked, deducted from the final bill
Fleet invoices with one line per registration
A surcharge line with a written reason
PDF invoices and a paid, unpaid and overdue list

What an auto detailing invoice must show

A detailing invoice should say exactly what was done to which car: the vehicle, the package, the size band, each add-on, and the product used for a coating if it carries a warranty. That last part matters when a customer comes back a year later with a question about their coating. Put the registration on every invoice so fleet managers and dealerships can match it to their records.

Package, size band and add-ons
Coating product and date applied

Deposits on correction and coating work

Coating and multi-stage correction jobs block days in your calendar and use product you buy in advance. Take a deposit when they are booked, record it against the job, and have the final invoice deduct it automatically. A cancellation then leaves you covered for the product and the lost day, and the customer sees one clear total at the end.

What to put in it first

Enter your packages with prices per size band, your common add-ons and your tax settings. Then add the customers you invoice regularly, especially fleet and dealership accounts. Raise this week's invoices in the app rather than the old way. Once the invoices are in, ask for a monthly view of revenue by package so you can see whether coatings or maintenance washes are carrying the business.

Mistakes to avoid

Do not add surprise charges without a reason line; if the car was worse than the photos showed, say so on the invoice and ideally on the quote first. Do not bill fleets one car at a time when they want one invoice a month. And do not leave deposits in your bank feed only; if the app does not know about a deposit, the final invoice will be wrong.

A prompt to start from

Build an invoicing app for my auto detailing business. Invoices have a number, date, due date, the customer's vehicle and registration, a package priced by size band, add-ons and tax. Coating bookings get a deposit invoice that is deducted from the final one. Fleet customers get one invoice with a line per vehicle. Generate PDFs and show paid, unpaid and overdue invoices.

Questions

Can it produce a PDF invoice?

Yes. Each invoice has a printable PDF you can download or email to the customer, with your logo and details.

Does it handle tax?

Yes. Set your tax rate and whether prices include it, and invoices show the tax line. Check the rules that apply to your business where you operate.

Can one invoice cover several fleet vehicles?

Yes. Ask for line items per vehicle with the registration and service, all on a single invoice, optionally raised monthly.

Can customers pay online?

Yes, if you connect a payment provider on your own account. Mythex adds a pay link to each invoice.

Do I need to code, and is it free?

No coding is needed. The Free plan has daily credits and no credit card, enough to build and publish it. Pro ($25/month) adds credits, a custom domain and the ability to edit code.
