Free Mobile Mechanic Invoice & Estimate Template (Word, Excel, PDF)

The call-out and the testing, both of which you performed whether or not the vehicle moved. Arriving is one line — Roadside jump / no-start call, or the diagnostic if it went further than a jump — and proving why it will not run is another, since a charging system test and a starting system test each stand on their own findings. Keep the haul itself off your invoice unless your truck is the one pulling it: show your part as a coordination line and let the wrecker bill the customer directly, so a damage claim against that tow has no route onto your paperwork. Write what the vehicle needs next, because the shop receiving it starts from your page, and record who took the keys and when.

The buyer pays, and the paperwork has to make it obvious the car was not theirs yet: the buyer in bill-to, the seller's address as the service location. Scope it in the terms you actually worked in — a Pre-purchase inspection done on the ground, nothing disassembled, no fluids sampled — and mark anything you could not reach as not inspected. Name the modules that answered a scan and the ones that would not. Then account for who else is standing there: the seller did not hire you and will be reading over your shoulder, so the findings leave in writing rather than as a conversation at the curb, and the copy you keep is the version anyone argues from afterwards.

As inspection time, with a verdict against every line the other shop wrote. Take their items one at a time and answer each in your own words — needed now, can wait, not needed, could not verify — and say what you measured to get there instead of asserting it. Then say plainly what you left alone: nothing came apart, nothing was road tested unless it was, and anything behind a wheel you never pulled stays unverified. Second-opinion review of another shop's estimate is a document that leaves your hands and gets shown to the shop it disagrees with, sometimes read back to you over the phone by a service manager, so it has to be measurements and dates and nothing about the other shop.

Enough that a return visit has something to compare against. Bill by the ounce, name the refrigerant, and show what you recovered apart from what you charged in. R-134a and R-1234yf are different refrigerants and come out on different recovery machines, so a customer with a newer vehicle should see which one went into their car rather than a line reading only recharge. On an A/C recharge & leak check, add the oil and any dye by the ounce as well, and write the static and operating pressures and the vent temperature you measured, because those readings are what a second visit gets compared against. A leak you found is its own repair line and never part of the recharge.
