    Water treatment company receipt FAQ

    Do I charge sales tax on water treatment work?

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

    Salt vs salt-free softener?

    Salt removes hardness; salt-free conditions. Salt is the standard for real hard water.

    RO water for pets/plants?

    Safe — though plants prefer non-RO. Note on invoice.
