Invoice template for plumber

How to fill it in

What goes on a plumber invoice

Write the job address, the date, and what you actually did — 'repaired leaking bathroom supply line' or 'installed kitchen faucet'. Put labor on its own line with the hours and rate, then list parts and fixtures separately. Add a permit number for jobs that needed one, choose a payment term like due on receipt or Net 15, and email the invoice from the van so it lands while the work is fresh.

Use this template for service calls, repairs, and small installations where the customer expects an itemized bill at the end of the visit. It also suits monthly maintenance contracts — bill one line per visit and keep the same invoice number series all year. For remodeling jobs, invoice per stage and reference the original quote.

Practical guide

Common mistakes to avoid

• Vague work descriptions. 'Fix leak' tells the customer nothing. 'Repaired leaking bathroom supply line, replaced compression fittings' is easy to approve.
• Hiding parts in the labor line. Fixtures and fittings belong on their own line. Customers accept materials costs far more easily when they can see them.
• No trip-fee note. If you charge a call-out fee, state it on the invoice. An unexplained charge is the fastest way to lose trust.
• Skipping the permit number. Permitted jobs should reference the permit on the invoice. It keeps the customer's records straight and yours too.
• Invoicing from home later. Half an hour of paperwork in the van beats a bill sent three days later. Send it while the job is fresh.

Tips to get paid faster

• Send the invoice from the van. Email the bill as you leave. Customers expect it from service pros and it starts your payment clock.
• Charge a diagnostic fee you credit back. A trip fee that's credited toward the repair encourages call-outs without punishing the customer.
• Keep a card on file for regulars. With permission, charge small balances to a stored card. It removes the 'check is in the mail' delay.
• Follow up at day 1 and day 7. One polite reminder shortly after the due date collects most slow payers. Escalate only if it stays unpaid.
• Number every invoice. A running INV-0001, INV-0002 series makes your own bookkeeping and year-end tax work far simpler.

Pricing your work

Plumbers usually charge a trip fee plus an hourly rate, with parts and fixtures billed separately at cost plus markup. Defined jobs like installing a water heater are often flat-quoted. Keep the call-out fee visible on the invoice and note whether it is credited toward the repair. For emergency work, state the emergency rate up front. Larger jobs take a deposit for fixtures, with the balance due on completion.

Real-world billing practices

Plumbers get paid at the front door, and the invoice should make the stop easy to approve. Bill the trip fee and the hourly labor as separate lines, with parts and fixtures itemized, and send it from the van the same day — customers expect it from service pros and it starts your payment clock immediately. State whether the diagnostic or trip fee is credited toward the repair, because an unexplained charge is the fastest way to lose trust. Permitted jobs need the permit number on the invoice for both your records and the customer's. Emergency rates should be confirmed on the phone and shown on the invoice, since after-hours work is where disputes most often start. Larger jobs take a deposit for fixtures and fittings, with the balance due on completion. Keep one invoice series for the whole year, and follow up once, politely, shortly after the due date — a single reminder collects most slow payers. The plumber with a clean, same-day invoice gets the repeat call; the one who mails a vague bill three days later gets forgotten.
