This septic invoice template is built for how septic work is really billed: by the tank and the gallon, plus the extras that eat a morning (finding the lid, digging, cleaning the effluent filter) and the disposal fee you pay at the plant. Copy the fill-in version below, then see a worked pump-out invoice with every line added up.
Quick answer: A septic invoice should show the property and tank (size, type, lid depth), each billable line (pump-out, extra gallons, locating and digging, filter cleaning, disposal, repairs or parts), the technician and truck, the manifest or disposal ticket number your county asks for, payment terms, and the date the next pump-out is due.

A septic invoice does two jobs a plumbing or HVAC invoice does not. It is a service record for a tank the homeowner cannot see, and it is often the only paper a buyer, inspector or county office will ask for when the house is sold. That is why the good ones carry the tank details and the disposal paperwork, not just a price. The EPA says household tanks are typically pumped every three to five years and should be inspected by a professional at least every three years (EPA, How to Care for Your Septic System, checked October 27, 2026), so an invoice that names the next due date is also your best repeat-business tool.
Copy this into your invoicing app or a document. Lines in brackets are what you fill in on site.

These prices are assumptions for illustration, not market rates. Use your own price sheet; our septic pumping cost calculator works out a pump-out price from your truck, time and disposal costs.
| Line | Quantity | Price | Amount |
|---|---|---|---|
| Pump-out, up to 1,000 gallons | 1 | $425.00 | $425.00 |
| Extra gallons (1,250-gallon tank) | 250 gal | $0.30 | $75.00 |
| Locate and uncover lid, 18 inches deep | 1 | $95.00 | $95.00 |
| Clean effluent filter | 1 | $35.00 | $35.00 |
| Disposal fee, manifest #[number] | 1,250 gal | $0.10 | $125.00 |
| Total | $755.00 |
Two things on this invoice pay you later. The finding "lid 18 inches deep, no riser" is your opening to quote a riser on the next visit, which turns a $95 digging line into a one-time sale and makes every future pump-out faster. And "Next pump-out due: October 2029" gives you a dated reason to call back in three years instead of hoping the customer remembers your name.
Most residential pump-outs are one-visit jobs, so the easiest invoice to collect is the one handed over before the truck leaves. Text or email the invoice from the driveway with a card link, and take payment then. For property managers and commercial accounts with terms, send the invoice the same day with the manifest number attached, and set a reminder for the due date; the longer it waits, the less likely anyone remembers the job.
Unmanually is a 24/7 AI Office Manager for septic companies that you run by voice. Say "Pumped the Miller tank, 1,250 gallons, dug 18 inches, cleaned the filter" from the truck, and the AI Office Manager writes this invoice from your price list, texts it with a pay link, files the manifest number, sets the pump-out reminder for three years out and chases the invoice if it is not paid. It also answers the backup calls that come in while you are on a job and books them. See Unmanually for septic companies, or read septic business software for the rest of the office.
The property, the tank size and type, gallons pumped, each billable line (pump-out, extra gallons, locating and digging, filter, disposal, repairs), the disposal manifest number, payment terms and the date the next pump-out is due.
Most price the pump-out up to a stated tank size and add a per-gallon charge above it, because a bigger tank means more time and higher disposal fees. Show the gallons and the rate as their own line.
Yes. The EPA says household tanks are typically pumped every three to five years, so writing the next due date on the invoice gives the homeowner a record and gives you a dated reason to call back.
Yes. Locating and uncovering a buried lid is labor, often priced by depth or time. Billing it as a line also helps you sell a riser, which makes future visits faster.
