Routine pumping is usually a flat fee based on tank size (typically 1,000 to 1,500 gallons), with extra charges for gallons beyond the base amount, long hose runs, or hard-to-find and buried lids. Inspections, camera work, and locating are priced as flat fees or by the hour. Repairs are billed by the hour or by the job plus parts, often with a markup of 15 to 30 percent on materials. Installs and drain field work are quoted as a fixed price after a site evaluation, and often depend on permits, soil tests, and excavation. Many shops add a trip or after-hours fee for emergency calls, and some sell multi-year maintenance plans. Disposal or dump fees at the treatment facility are either built into the pumping price or passed through as a separate line.

Notes: Payment due upon completion. Total gallons pumped recorded on manifest and disposed at licensed facility. Next pumping recommended in 3 years. Late balances charged 1.5% per month after 30 days.
Customers often own several properties, and the record needs to show which system was serviced and where the tank and lids were found.
Justifies the base price and gives the next technician a record of what is in the ground.
Supports any per-gallon charge and shows the waste went to a licensed facility. Many states require a manifest or pumping record.
Many states and counties require licensed haulers or installers, and health departments or lenders may ask for it.
Notes on cracked baffles, standing water, or a failing filter protect you if the system fails later and give the customer a reason to approve repairs.
Risers, lids, filters, pipe, and pumps should be listed separately so the markup is clear and warranty claims are easy.
Ties your work to the local health department record and may be needed for final approval or a home sale.
Routine pumping and inspections are typically due at the time of service, by card, check, or electronic payment, since the truck is already at the property and collecting later is harder. For repairs, many shops take a deposit of 25 to 50 percent to cover parts, and installs commonly use a deposit, a progress payment after excavation or tank set, and a final payment after the inspection passes. Net 15 or Net 30 is common for property managers, realtors, and commercial accounts. If you charge late fees, state them on the estimate and the invoice, and check your state's rules on interest limits.
Pumping is a one-visit job and the customer is usually home. Sending a payment link or taking a card on site avoids chasing small balances that cost more to collect than they are worth.
Buried lids are the most common source of lost time. Bill locating and excavation by the hour or as a set fee, and tell the customer before you start digging.
A line such as pump again in 3 years gets repeat work and doubles as a service record. Many customers keep invoices for the home sale.
Real estate inspections are often paid by the buyer or agent, not the owner. Invoice the right party and keep the report with the bill so there is no dispute about who ordered what.
Treatment plant tipping fees change. Either review your flat pumping price each year or list disposal as its own line so increases do not come out of your margin.
Most residential shops charge a flat fee for a standard tank size and add a per-gallon charge only if the tank is larger or you pump more than the base amount. Commercial and grease trap work is more often priced per gallon.
In many states, haulers must keep pumping records or manifests showing where waste went. Listing gallons pumped and the disposal site on the invoice is a simple way to keep that record, but check your state and county rules.
Tell the customer before continuing, then bill the extra time or a heavy-waste surcharge. Note the condition on the invoice. If it was not agreed beforehand, expect pushback.
It depends on the state. Some tax services, some tax only parts and materials, and others tax neither. Check with your state revenue department and show any tax as its own line.
Send a reminder with the invoice and your terms, then a formal demand letter. Depending on your state, you may be able to file a mechanic's lien on larger repair or install jobs, so keep signed estimates and photos of the work.
Send a Septic Service estimate for approval, then turn it into an invoice when the work is done.
