Marine Mechanic Invoice Template (Free)
A marine mechanic's invoice needs the vessel identified (name, make, HIN or engine serial), the complaint, parts itemized, labor by the hour, and a dock-call or travel line for mobile work — plus terms saying payment is due on completion. Copy the template below, or use invoicing software that builds it from the quote and takes payment at the slip.

An invoice without the engine serial is a receipt. With it, it’s a service record — one you can pull up when the same customer calls next season, and one that settles a warranty question in seconds.
Skipping the copy-paste
A blank template still has to get filled in at a dock, in the wind, on a phone. Invoicing software with your parts and rates saved builds this in a couple of taps and takes the card before you leave the slip.
Frequently asked questions
Why put the engine serial on the invoice?
Because a warranty or repeat-repair question a year later starts with which engine you touched. The serial and hours turn a long conversation into a records lookup.
Should the dock call be its own line?
Yes. Getting to a boat is a real cost, and pricing it separately keeps your labor rate honest instead of inflated to cover travel you never named.
How do I invoice a job where the part came later?
Show the diagnostic visit and the repair visit as separate labor lines with the part itemized between them. The customer sees exactly what each trip covered and why there were two.
