Why it's laid out like that
The lines follow how the job was actually priced: a call-out and diagnostic charge, labour by the hour, and parts fitted with their warranty stated. Each part is separately checkable, which is the whole point — a customer who can verify the bill pays it.
On completion, on the driveway, before you leave. Card or transfer on the spot is normal in this trade.
Common questions
- What vehicle details should be on a mechanic's invoice?
- Make, model, registration and mileage at the time of work. It turns the invoice into a service record the owner can show a future buyer.
- Should diagnostics be charged if the repair goes ahead?
- That is your call, but say which on the invoice. Many mechanics show the diagnostic charge and then discount it when the repair is booked — visibly, as a line.
- How long should a parts warranty be?
- Twelve months or 12,000 miles is the usual standard for fitted parts. Put it on the invoice so there is no argument if the part fails.
