Getting paid promptly is just as important as fixing the leak. A clear, professional plumbing invoice tells your client exactly what work was done, what parts were used, and how much is owed — eliminating disputes and speeding up payment.

Whether you run a sole-trader plumbing business or manage a team of tradespeople, this guide covers everything you need to create a professional plumbing invoice and get paid faster.

What to Include on a Plumbing Invoice

1. Your Business Details

Business name and logo — e.g., "Smith Plumbing Services" with your company logo
Your plumbing licence number — legally required in most states and countries
ABN / Tax ID / Company registration number
Phone, email, and business address
Insurance certificate details — e.g., "Public Liability Insured — $10M"

2. Client Details

Client full name or company name
Service address (where the work was carried out)
Client phone and email for follow-up

3. Invoice Reference

Invoice number (e.g., PLM-2026-047)
Job date — date the work was performed
Invoice date — date issued
Due date — typically 7 to 14 days for residential, 30 days for commercial

4. Itemised Line Items

Always break down your invoice into individual items. Never write just "Plumbing Work — $850." Itemisation prevents disputes and looks professional. Common plumbing line items include:

Call-out fee / Service call — $80–$150
Labour — Pipe leak repair (1.5 hours @ $110/hr) — $165
Materials — 15mm copper pipe (3m) — $45
Materials — Push-fit fittings (x4) — $28
Hot water system replacement (unit + installation) — $1,650
Drain clearing — High-pressure jet clean — $280
Bathroom renovation rough-in (labour, 8 hours @ $110/hr) — $880
After-hours surcharge (50%) — $55
Disposal fee — $30

5. Taxes (GST / VAT)

In Australia, add 10% GST if your annual turnover exceeds $75,000. In the UK, add 20% VAT if VAT-registered. In the US, labour is generally not taxed but parts may be — check your state's rules.

6. Payment Details

Bank BSB and account number
PayID or payment link (BPAY, Stripe, Square)
Payment terms: "Payment due within 7 days of invoice date"
Late fee clause: "A 2% monthly fee applies to overdue accounts"

How to Price Your Plumbing Work

Call-Out Fees

Always charge a call-out or service fee — even if the job is small. This covers your travel time, fuel, and the cost of showing up. Typical call-out fees range from $80 to $150 for residential, and $150–$250 for after-hours or emergency work.

Labour Rates

Plumbing labour rates vary by region and experience:

Australia: $100–$160/hour
USA: $45–$200/hour depending on state
UK: £40–£100/hour
Canada: CAD $70–$150/hour

Materials Markup

Most plumbers add a 15–25% markup on materials. This is completely standard and covers your time sourcing, transporting, and managing inventory. Always list materials as separate line items rather than rolling them into the labour cost.

Frequently Asked Questions

Do I need to include my plumbing licence number on invoices?

Yes — in most Australian states, the UK, and many US states, licensed tradespeople are legally required to display their licence number on all invoices, quotes, and contracts. Failure to include it can create legal issues and may void your insurance coverage for that job.

How do I invoice for emergency or after-hours plumbing?

Add an "After-Hours Surcharge" or "Emergency Call-Out Fee" as a separate line item. Most plumbers charge a 50–100% premium for after-hours, weekend, or public holiday work. State this clearly on the invoice so the client is not surprised.

What is the best payment term for plumbers?

For residential jobs, "Due on Completion" or "Net 7" (within 7 days) is standard. For commercial clients or large renovation projects, "Net 30" is acceptable but consider requiring a 25–33% deposit before starting. Always include a late payment fee clause to incentivise on-time payment.

Can I charge for warranty call-backs on plumbing work?

Most professional plumbers offer a 3–12 month workmanship warranty. If a client calls back within the warranty period for the same issue, you would typically not charge for labour — but you can charge for additional parts if the problem is unrelated to the original work. Always specify your warranty terms on every invoice and quote.
