Invoice template for plumbers.
A plumber invoice should list the call-out fee, the labour hours at the agreed trade rate, every part used with its price (and any markup disclosed), the job address, the date and arrival/departure times, plus warranty terms on the work performed. Inbill's Corporate template structures these categories cleanly so customers can match every line to what was done in the property.
Recommended template
Corporate — why it fits
A formal, structured layout with strong column dividers — needed when an invoice has to itemise the call-out fee, labour by trade rate, parts (with mark-up disclosed), and any after-hours premium so the homeowner sees exactly what they are paying for.
Open this template in InbillWhy invoicing matters for plumbers
A plumber's invoice is the document that decides whether a homeowner pays the same day or pushes back two weeks while "checking the price." Trade work is high-trust — somebody let you into their kitchen — and high-suspicion at the same time, because every customer has heard a story about being overcharged. The fix is transparency on the invoice itself: the call-out fee on its own line, labour hours timestamped, every part listed at its price (with the markup disclosed up front in the contract or quote), and a clear warranty on the work. Generic Word-doc invoices that just say "plumbing — $480" are exactly what triggers customer pushback, even when the price is fair. Inbill's Corporate template gives the document the structured, by-the-book look that homeowners and property managers trust, and the line-item layout makes it impossible to hide costs even if you wanted to. The clearer the invoice, the faster the wire arrives and the more likely you are to be the first call next time something leaks.

On rates
How much should plumbers charge?
Plumbing rates in 2026 vary widely by region and by the type of work — a residential service plumber in the rural Midwest might bill $75/hour while a licensed master plumber in a major US coastal market bills $200+. Most independent plumbers mark up parts by 20–40% to cover sourcing time, supply-house runs, and the cost of holding common stock on the truck. This markup should be in your contract and quote, not hidden on the invoice. The single biggest pricing mistake plumbers make is undercharging for after-hours work — a 2 a.m. burst-pipe call that ruins your sleep should be 1.5–2x your day rate, with a clearly named "emergency premium" line on the invoice. Customers expect emergency work to cost more; what they don't expect is a "surprise" double rate on a regular invoice.
How to send the invoice
Sending your first invoice as a plumber.
- 01
Pick the Corporate template
Open Inbill, choose Corporate. The structured columns suit invoices with a call-out fee, labour, parts, and any after-hours premium.
- 02
Put the job address and arrival/departure times in the project field
Write something like "12 Maple Drive — Kitchen sink and dishwasher leak, 2026-05-02 09:15–11:40." Anchors the invoice to a specific visit and protects you in any later dispute about hours billed.
- 03
List the call-out fee and labour separately
Never bundle the call-out into the labour rate — homeowners read it as either "free travel" (and complain when it appears) or as overcharging. A separate line shows it clearly.
- 04
Itemise every part used at its price
List the part, the brand if relevant (e.g. "Grohe ceramic disc cartridge"), and the price including your disclosed markup. This is what makes warranty claims and subsequent service calls easy.
- 05
Add a warranty clause and Net 7 terms
In Inbill's Notes field write "Workmanship warranty: 12 months. Parts: per manufacturer. Payment due within 7 days." A short clause sits directly below the line items where the customer reads it.
Frequently asked
Plumber invoice questions, answered.
Should a plumber charge for the call-out separately or include it in the labour rate?
Charge it separately and put it on its own line. Bundling the call-out into a higher hourly rate makes short visits look expensive and long visits look cheap — both confuse customers. A flat call-out ($75–$200 depending on region) plus a clearly stated hourly labour rate is the format every customer recognises and the format that produces the fewest disputes. If your trip is unusually long (over 30 minutes), bill mileage as a separate line too.
How much should plumbers mark up parts and materials?
A 20–40% markup is standard for residential service work and covers your time at the supply house, holding common stock on the truck, and waste/return costs. Always disclose the markup in your quote or contract — customers don't mind paying it when they see it coming, but feel cheated when they discover it after the fact. On the invoice, list each part at its delivered price (with the markup baked in); you don't need to show the wholesale cost.
What payment terms work for plumbing invoices?
Net 7 for residential work, Net 14–30 for property managers and small businesses, Net 30 for commercial accounts and contractors who pay on draw schedules. For large jobs over $1,500, take a 30–50% deposit upfront. Add a late-fee clause (1.5% per month) and a clear payment method — most independent plumbers should accept bank transfer, card, or cash. Inbill's hosted public link lets the customer pay or forward the invoice to a spouse without needing an account.
Do plumbers need to charge sales tax on labour?
It depends entirely on jurisdiction. In most US states, plumbing labour on residential repair is taxable; labour on capital improvements (a new bathroom rough-in, a re-pipe) is often exempt. Parts are usually taxable everywhere. In some states (NJ, NY, CT) the rules split between repair vs improvement and you need to track carefully. Register with your state department of revenue, read the contractor-specific guidance, and add a tax line in Inbill only on the categories you're required to collect.
How should plumbers handle emergency / after-hours invoicing?
Use a separate, clearly-named "after-hours premium" or "emergency call-out" line at 1.5–2x your standard call-out fee, plus a higher hourly rate for the labour itself. Tell the customer the rate BEFORE you leave the house — text or call confirms the number. Surprise emergency rates on an invoice are the single most common cause of payment disputes for trade work. A two-line text ("I can be there in 45 minutes; the after-hours call-out is $250 plus $150/hour") protects everyone.
