What is a plumbing invoice?
A plumbing invoice is the bill you give a customer after a repair, installation or service call. It lists the labor, parts and fees for the job and tells the customer how much to pay and by when. A clear invoice also serves as the customer’s record for warranty claims and your record for taxes.
This free template works for residential and commercial plumbers. It includes the service address, work order number and license number, and calculates totals, tax and the balance due as you type.

How plumbers price their work
Flat rate
A fixed price per job, such as replacing a faucet or a water heater. Customers know the cost up front, and you are rewarded for working efficiently.
Time and materials
Hourly labor plus parts at cost or with a markup. It works best for leak detection, remodels and jobs with unknown conditions.
Service agreements
Recurring maintenance for property managers and commercial clients, billed monthly or per visit.
Common plumbing invoice mistakes
- Vague descriptions. “Repair” tells the customer nothing. “Replaced shut-off valve under bathroom sink” explains the price.
- Missing the service address. Landlords and property managers own many buildings and need to know which one the bill is for.
- Forgetting truck stock. Small parts from your van, such as supply lines and wax rings, add up. Record them before you leave.
- No warranty information. Note the warranty on parts and labor so the customer knows what is covered.
- Extra work without approval. If you found a second leak, get the customer’s OK and list it as a separate line.
Fixing these small details makes your invoices easier to approve and reduces calls asking what a charge was for.
Tips to get paid faster
- Invoice before you leave. Fill in the invoice on your phone and send it while you are still on site.
- Explain the work in plain words. “Replaced leaking supply line under kitchen sink” is easier to approve than a part number.
- Offer card payments. Customers pay faster when they can pay right away.
- Follow up on unpaid invoices. A friendly reminder before and after the due date recovers most late payments.
