Free Septic Service Invoice & Estimate Template (Word, Excel, PDF)

Bill the party who ordered it, then let the line items describe septic work rather than inspection in the abstract. A point-of-sale certification is usually a combined visit: the tank opened and pumped, the baffles and effluent filter checked, a dye test run from the fixtures, the field walked for surfacing, and, where the county requires one, a compliance certificate completed and filed. Those are line items, not one inspection charge, and the filing fee is another, since it leaves your hands and goes to a public office. Where a lender wants an FHA or VA package, the well and septic setback distances get measured and drawn, which is survey work, not part of a pumping. If repairs follow, a re-inspection after repair is a second visit carrying a second document.

Enough about the pump chamber that the next alarm does not land on this visit. A high-water alarm means the chamber is holding effluent it should have dosed out, and the trip is the same work whether the fault is a float off its tether or a seized 1/3 hp effluent pump: you read the panel, lift the float tree, try the manual override, and usually pump the chamber down before you can reach the pump at all. Put the call and the repair on separate lines, horsepower on one, float count and the tether settings you left it at on the other. Then write whether you silenced the alarm or left it live, because a customer who hears nothing for a week decides the system is fixed.

Name the unit, number the visit, and list what you touched, then price consumables apart from the visit. An aerobic maintenance contract commonly buys three visits a year, so the invoice for the second one says which visit it is and still itemizes: aerator and diffuser checked, air line cleared of condensate, chlorinator inspected, effluent drawn for a BOD and TSS lab submittal. Consumables and repairs sit on their own lines — tablets by the count left in the feeder, an aerator rebuild kit, a UV lamp, a diffuser assembly. Pumping an aerobic unit is a separate job again, because the trash tank and the clarifier come out apart from the aeration chamber. Where your state ties an operating permit to a current service agreement, print that agreement's end date on every invoice.

Write it so it lines up with a record somebody else is keeping. A restaurant's trap runs on a pumping interval set by the local fats, oils and grease program, and your invoice is what shows the interval was met, so it needs the trap capacity, the gallons removed, the date and clock time on site, and the manifest number for the load. Say what the visit actually was — a full pump with a baffle scrape reads nothing like a skim off the top — and put trap line jetting on its own line when the outlet is packed. Scheduling belongs there too: kitchen access is usually after close, and route work like a monthly trap plan or a lift station wet well bills on terms rather than at the truck.
