What to Include on a Plumbing Invoice
A professional plumbing invoice should include your business name, license number (legally required in most states), customer name and service address, the date of service, a description of the problem diagnosed, the work performed, parts used with quantities and prices, labor hours, your hourly rate, any after-hours or emergency surcharge, applicable taxes, and warranty terms. Reference the work order or job number for your records.
Tips for Plumbing Invoicing
Always disclose your service-call fee upfront before dispatching — it's standard but customers should know. Bill parts at retail (typically 1.5–2× your wholesale cost) to cover sourcing, pickup, and stocking. Use flat-rate pricing for common jobs (water heater install, faucet replacement) rather than time-and-materials — it removes pricing arguments. Document warranty terms clearly: most parts carry a manufacturer warranty; labor warranties of 30–90 days are standard.
Frequently Asked Questions
How much should plumbers charge per hour?
Plumber labor rates typically range from $75–$200 per hour in the US, depending on region and license level (apprentice vs journeyman vs master plumber). Major metros (NYC, SF, LA) often charge $150–$200+. Service-call/dispatch fees of $50–$150 are also standard, sometimes credited toward repair.
Should plumbers use flat-rate or time-and-materials pricing?
Flat-rate pricing is preferred by most modern plumbing businesses — it eliminates customer arguments over hours and gives them cost certainty before you start. Time-and-materials is appropriate for unpredictable diagnostic work or major repairs where scope can't be fully known upfront.
Do I need to include my plumbing license number on invoices?
Yes — most US states require licensed contractors to display their license number on every invoice and contract. Failure to do so can void your right to enforce the contract and may result in fines. Include it in your invoice header alongside business name and address.
What's a fair markup on plumbing parts?
Standard parts markup is 1.5–2× wholesale cost. The markup covers your time sourcing the part, fuel for pickup, warehouse stocking, and warranty exposure. Some plumbers itemize parts at retail; others bundle parts into a flat-rate price. Both are accepted industry practice.
How do plumbers charge for emergency or after-hours service?
Typical surcharges: 1.5× the standard labor rate for after-hours weekday calls, 2× for weekends, 2.5–3× for major holidays. Disclose the surcharge before dispatching to avoid disputes. Some plumbers also charge a higher dispatch fee ($150–$250) for emergency calls.
What warranty should plumbers offer on labor and parts?
Industry standard: 30–90 days on labor, manufacturer warranty on parts (typically 1–10 years). Some shops offer extended warranties as an upsell. Always state warranty terms in writing on the invoice and include exclusions (clogs caused by foreign objects, freeze damage, etc.) to avoid future disputes.
