    Basement waterproofing company invoice FAQ

    Do I charge sales tax on waterproofing work?

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

    Interior or exterior?

    Interior = cheaper, less invasive. Exterior = better for hydrostatic. Quote both.

    Warranty length?

    Lifetime transferable is the standard. Print terms.
