Septic companies send estimates for repairs, replacements, new installs, and drain field work, where the cost depends on what is found in the ground. Routine pumping is usually quoted by phone. Customers comparing quotes are looking at scope, permit handling, and whether excavation and restoration are included.
When to use estimates: Use estimates to provide project quotes and get client approval before starting work. Once approved, convert your estimate to an invoice with one click to collect payment.

A conventional gravity system, a pump-assisted system, and an aerobic system have very different costs, so name what you are quoting.
State whether you are replacing a baffle, a pump, a distribution box, lateral lines, or the whole tank, so the customer does not assume a full fix when you quoted a partial one.
These can add hundreds or thousands of dollars and take weeks. Say who pulls the permit and who pays for it.
Disputes often start over grass, landscaping, driveways, or trees. State what you will restore and what you will leave rough graded.
Rock, high water table, or a collapsed line may be found only once digging starts. Explain how extra work will be priced and approved.
State that final payment is due after the health department inspection passes or after completion, whichever you have agreed to.
Material and fuel costs move, and permit timing affects start dates. Give an expiration date and a rough timeline.

Typical US ranges. Rates vary by region, experience, and job size.
Do not quote repairs over the phone. A quick look, a probe, or a camera run lets you give a firm number and avoids eating the cost of surprises.
A failing system might be fixed with a pump and filter now, or by replacing the drain field. Presenting options with costs lets the customer choose and shows why the bigger job is needed.
Customers accept line items for tanks, pumps, stone, and pipe more readily than one large number, and it makes change orders easier to explain.
Add a reasonable allowance for weather, rock, or a longer pipe run, or state a per-hour or per-yard rate for extras so you are not absorbing the overrun.
Most shops do not charge for pumping or simple repair quotes. For installs or system designs that need a site visit, soil work, or drawings, many charge an evaluation fee and credit it toward the job if accepted.
Thirty days is common for repairs. For installs tied to permits and material pricing, 14 to 30 days is typical. State the date on the quote.
Only if the quote says how unknown conditions are handled and the customer agrees to the change in writing. Without that, you are generally held to the quoted price.
For anything beyond routine pumping, get a signature or written approval. Many states require written contracts for home improvement or installs over a set dollar amount, so check your local rules.
