The short answer

Get the invoice ready before the customer collects. Parts and labour on separate lines, the registration and mileage on top, and a card payment option.

What a garage invoice includes

  • Vehicle registration, make and mileage
  • Parts, each priced
  • Labour hours and rate
  • Advisories for future work
  • VAT if registered, total and how to pay

Estimates first

Send an estimate before big jobs. On SaidToPaid Pro, customers can accept it online, so there's no argument at collection.

Invoice terms you can copy

Plain wording to add to the notes on your invoices. Save it once in your settings and it goes on every invoice. General guidance, not legal advice.

Late payment (business customers)

Payment is due within 30 days of the invoice date. If you are a business customer, we may charge interest on late payment at 8% a year above the Bank of England base rate, plus fixed compensation, under the Late Payment of Commercial Debts (Interest) Act 1998.

Parts warranty

Parts supplied carry the manufacturer's warranty only. Customer-supplied parts are fitted at the customer's risk and are not covered for labour if they fail.

Diagnostics

Diagnostic time is charged even if the customer chooses not to go ahead with the repair.

Waste disposal

A disposal charge applies for used oil, filters, batteries and other waste removed from the vehicle.

The late payment law only covers business-to-business invoices. Fixed compensation is £40 on debts under £1,000, £70 up to £9,999.99 and £100 from £10,000.
