Plumbing Invoice Template

This free plumbing invoice template is built for the people who actually turn the wrench — solo plumbers, service and repair shops, and emergency call-out crews who need to bill a job before they're back in the truck. Whether you fixed one leaking sink this morning or your team runs a dozen calls a week, it gives you a professional invoice without a spreadsheet, an accountant, or a subscription. Fill in your details, hand it to the customer, and get paid on the spot, because most plumbing customers expect to settle up the same day the work is done.

A good plumbing invoice earns its keep by separating the call-out fee, the labor hours, and the parts, so the total explains itself instead of arriving as one flat number a customer has to take on faith. That matters most on emergency and after-hours jobs, where the bill needs to hold up the moment you hand it over — before you leave the driveway, not after a follow-up email next week. The generator below is already pre-filled with a realistic plumbing invoice you can edit line by line: change the fee, hours, parts, and customer details to match your own job, then download the finished PDF.

How to fill out a plumbing invoice

  1. Start with your business details

    Put your plumbing business name at the top — the same name your bank account uses, so payments reconcile — with your address, phone, and email under it. If your state or city licenses plumbers, add the license number on its own line. Homeowners approving a water heater or repipe bill often look for it before they pay.

  2. Add the customer and the service address

    Bill the party who actually pays, which is not always the person who let you in. A tenant may have called about the leak while the landlord or a home warranty company covers the bill. List that payer's name, billing address, and email, then put the service address and unit number on its own line so the job is easy to identify later.

  3. Number the invoice and set both dates

    Give every invoice a unique number in one running sequence — INV-3311, then INV-3312 — and never reuse one. Add the date you did the work and a due date. Same-day service calls are usually "due on receipt"; a scheduled install for a builder or property manager may need net 15 or net 30 instead.

  4. Describe the repair line by line

    Write what you actually did, with the fixture and the location: "Cleared kitchen branch line — 50 ft cable from cleanout" or "Replaced 40-gallon gas water heater, garage." Start with the call-out or trip fee on its own line, then a labor line per repair. A homeowner reading it six months later should still know what got fixed.

  5. Set hours and rates the way you price

    Hourly work goes in as hours: two hours under the sink is a quantity of 2 at your labor rate, and a two-man crew for three hours is six units, not three. Flat-rate repairs get a quantity of 1 and the quoted price. If you bill a minimum or an after-hours rate, use those numbers here rather than your standard daytime rate.

  6. Add parts, permits, and any deposit

    Parts get their own lines — P-trap and fittings, a mixing valve, the water heater itself — priced at your cost plus markup or at your standard retail price. Add permit fees and dump or haul-away charges as separate pass-through lines so nobody thinks they are labor. If the customer prepaid a deposit on a repipe, show it as a negative line.

  7. Set the tax line for your state

    Plumbing tax rules split by state: some tax the parts you install but not your labor, some tax the whole repair invoice, and some treat new construction differently from a service call. If you are registered to collect sales tax, enter your rate and let it run on the subtotal. If you are not registered, leave it at zero.

  8. Close with terms, warranty, and payment

    Spell out the terms in plain words — "Due on receipt" for a service call, or a dated deadline for a bigger job — and add your warranty period on labor so a call-back has an answer already in writing. Then list every way you take money, with the exact Zelle number or Venmo handle, so nobody has to call and ask.

Billing tips for plumbing invoices

Structure the invoice around three line items

Break every job into three parts: the call-out or trip fee, labor billed by the hour, and parts or materials as their own line. Listing them separately means the customer can see exactly what they are paying for instead of questioning one lump sum. It also protects you — if a repair runs long or needs an extra fitting, you can point to the specific line instead of re-explaining the whole job from scratch.

Invoice on-site, before you leave the job

The best time to bill a plumbing job is the moment it's finished, while you're still standing in the customer's kitchen or bathroom. Write or send the invoice before you pack up the van, and ask for payment on the spot — card, check, or a payment app. Waiting until you're back at the shop to invoice is how call-out jobs turn into bills nobody remembers to open, chase, or pay.

Sales tax on plumbing work varies by state

Labor is often exempt from sales tax, while parts and materials are frequently taxable — but the split, and whether it applies at all, depends entirely on your state and sometimes the type of job. Some states tax the whole invoice for certain repairs; others tax nothing on residential work. The sample above uses a 0 percent rate, so check your state's rules and set the correct tax rate before you send a real invoice.

Note your warranty to head off call-back disputes

Most plumbing repairs carry some kind of warranty — commonly 90 days on labor, sometimes longer on parts if the manufacturer backs them. Put that warranty period in writing on the invoice itself, not just as a verbal promise on the job. If the customer calls back with a related issue, the invoice already answers whether it's a free fix or a new charge, which keeps a callback from turning into an argument about what was originally promised.

Frequently asked questions

Do plumbers need to give an invoice?

For a quick cash job you technically don't, but you almost always should. An invoice gives the customer a clear record of the call-out fee, labor, and parts they paid for, protects you if a dispute comes up over the price, and makes you look like a licensed professional instead of an off-the-books handyman. It's also what you need at tax time to show your income and to back up any warranty claim.

What should a plumbing invoice include?

Your business name and contact details, the customer's name and address, an invoice number, and the date. Then an itemized breakdown of the job — the call-out fee, labor hours, and any parts used — each with its own rate, plus a subtotal, tax if it applies, and the total due. Close with your payment terms, the ways you accept payment, and your warranty period.

How do I bill for parts vs labor?

Keep them on separate lines. Bill labor by the hour, or as a flat repair rate, and list parts — fittings, valves, a new disposal — at what you paid plus your markup, or at a standard retail rate if that's how you price. Splitting them out shows the customer they aren't being charged labor rates for parts, and it makes it easy to adjust one line without rewriting the whole invoice.

Can I add a late fee for overdue invoices?

Yes. State the late fee policy on the invoice itself before the due date passes — a common approach is 1.5 percent per month on the unpaid balance, or a flat fee after a set grace period. Customers are far more likely to accept a late fee they were told about up front than one that appears out of nowhere. Keeping track of which invoices are overdue by hand gets hard once you have more than a few customers, which is the kind of tracking the Paid app on iPhone handles automatically.

What should I charge for an emergency or after-hours call?

Set an after-hours rate before the phone rings at midnight, not while you are standing in a flooded basement. Most shops use a higher call-out fee, a higher hourly labor rate, or both for nights, weekends, and holidays, and quote it on the phone before rolling a truck. Whatever you land on, put it on the invoice as a clearly labeled line — "After-hours service call" — so the customer sees the premium is the schedule, not the repair.

Who pays for the permit on a water heater or sewer job?

The customer does, in almost every case, but you are usually the one who pulls it. Water heater replacements, repipes, sewer line work, and gas line work commonly need a permit and an inspection — check with your local building department, since the trigger varies by jurisdiction. Bill the permit fee at cost on its own line, labeled as a permit, and note the permit number on the invoice so the inspection has a paper trail.

What do I do when a plumbing invoice goes unpaid?

Start with a short, friendly reminder that restates the invoice number, the work, and the balance — plenty of unpaid invoices are just buried in an inbox. If that gets nothing, call, then send a written statement with the late fee you already disclosed applied. For large unpaid jobs, some states let a licensed contractor file a mechanic's lien, but the deadlines are tight and vary by state, so look up your own rules early rather than after the window closes.

Is this plumbing invoice template really free?

Yes — fill it in and download the PDF with no signup, no watermark, and no catch. Use it for a single emergency call or every job you run this month. If you later want to store customer details, see who still owes you, and rebill repeat customers without retyping their information, the Paid app on iPhone does that — but you never need it to use this template.
