Free Mechanic Invoice Generator

A mechanic's invoice should separate parts from labour and clearly state OEM versus aftermarket for major components, since clients care and disputes are common. Bill labour in flat-rate hours per an industry labor guide like Mitchell or Alldata, with the shop rate per hour stated, since flat-rate is the industry standard and gives the customer a predictable price. List the diagnostic fee as its own line, with a policy on whether it is waived if the repair is approved. Disclose shop supplies as a small line item or disclosed percentage, since hidden shop-supplies charges are the top cause of customer complaints. State warranty terms, typically twelve months or twelve thousand miles on parts and labour. The most common mistakes are quoting a flat brake job fee with no parts or labour split, leading to objections that the pads could be bought for eighty dollars; billing labour by clock hour instead of flat-rate hour, which under-bills for fast work; adding shop supplies as a vague line without disclosing the percentage; and not specifying OEM versus aftermarket parts. One practical tip: collect payment at vehicle pickup, before the customer drives off.
