    Boat & marine mechanic invoice FAQ

    Do I charge sales tax on marine repair work?

    Most US states tax parts/materials but exempt labor. Use Glo Invoice's per-line tax toggle so each marine repair line item is taxed correctly. Check your state — a few (HI, NM, SD, WV) tax services too.

    Do I need to track hours?

    Yes — hours drive service intervals. Print hours in/out on every invoice.

    Saltwater vs freshwater pricing?

    Saltwater = +20% labor — corrosion adds time. Disclose upfront.
