How to Create a Plumbing Invoice
Step 1 — Your Business and Licence Information
Enter your plumbing business name, address, phone, email, and logo. Like electrical work, most states and jurisdictions require plumbers to display their plumber’s licence number on all business documents including invoices.
Why Your Licence Number Belongs on Every Invoice
Property managers, landlords, and commercial clients regularly require proof of licensing before releasing payment. Insurance companies processing claims for water damage repairs need your licence number for their records. A missing licence number is one of the most avoidable reasons a plumbing invoice gets delayed.
Step 2 — Client Details and Service Address
Enter the client’s name and billing address. For plumbing work specifically — always add the service address separately if it differs from the billing address. Rental property owners, property managers, and commercial clients typically have a head office billing address completely separate from the job location.
Step 3 — Labour: Flat Rate or Hourly?
Plumbing billing uses two distinct pricing models. Choosing the right one — and showing it clearly on your invoice — prevents more disputes than almost anything else.
Flat Rate Plumbing Billing
Flat rate pricing charges a fixed amount per job type regardless of how long it takes. Most residential plumbing businesses use flat rate for common jobs like drain unclogs, tap replacements, and toilet repairs.
Flat rate line item format:
Blocked drain — kitchen sink clearance 1 job $195.00 $195.00
Tap replacement — bathroom mixer 1 job $165.00 $165.00
Toilet suite replacement 1 job $285.00 $285.00
Flat rate invoices are simpler for clients to understand and faster to create. The trade-off is that unusually complex jobs may under-recover your time.
Hourly Rate Plumbing Billing
Hourly billing is standard for jobs where the scope is uncertain upfront — fault finding, complex leak detection, commercial maintenance, and large installations.
Hourly line item format:
Call-out / travel fee 1 flat $85.00 $85.00
Labour — leak investigation 1.5 hrs $115/hr $172.50
Labour — pipe repair 2 hrs $115/hr $230.00
After-hours surcharge 1 flat $120.00 $120.00
Step 4 — Truck Charge and Call-Out Fee
The most commonly asked question in plumbing invoicing: what do you put on a professional invoice for a truck charge?
How to Describe Truck and Call-Out Charges
The clearest description is also the most professional. Use one of these:
- “Service call / call-out fee” — most widely understood
- “Travel and mobilisation fee” — preferred for commercial clients
- “Truck charge — [suburb/area]” — acceptable for residential
Avoid vague descriptions like “fee” or “surcharge” — these attract disputes. A clearly labelled call-out fee with a fixed dollar amount is expected and accepted by most residential clients.
Standard call-out rates (2026):
- Standard call-out (business hours): $65 – $95 flat
- Emergency call-out (after hours): $150 – $250 flat, or 1.5–2x hourly rate
Step 5 — Parts, Pipes, and Fittings
Every material used on the job should appear as an individual line item with description, quantity, unit cost, and your markup.
Plumbing Materials Markup
A markup of 15–30% on materials is standard in the plumbing trade. This covers procurement, transport to the job, and van stock. List the base cost and markup separately, or fold the markup into the unit price — either approach is acceptable as long as totals are clear.
Example materials section:
Copper pipe 15mm — 2m lengths 3 lengths $18.50 $55.50
Compression fitting 15mm elbow 6 units $4.20 $25.20
Ball valve 22mm 1 unit $28.00 $28.00
PTFE tape 2 rolls $1.50 $3.00
Materials markup (20%) $22.34
Labelling Pipe Sizes and Fittings Clearly
For residential clients, pipe specifications look like technical jargon — keep descriptions plain where possible. “Hot water pipe — kitchen” is clearer than “22mm copper tube EN1057 type X.” Save the technical specs for commercial invoices where accounts payable departments need precise part references.
Step 6 — Tax, Terms, and Download
Apply sales tax to materials only in most US states — plumbing labour is generally not taxable but rules vary by state. Add your payment terms, warranty statement, and download.

Plumbing Invoice Line Items — By Job Type
Emergency Plumbing Call Invoice
Emergency jobs are the most common source of invoice disputes — mainly because clients are in crisis when they agree to the work and only scrutinise the cost afterwards. Clear billing prevents this.
Emergency Invoice Structure
Emergency call-out fee (after hours) $185.00
Labour — burst pipe repair 2.5 hrs @ $130/hr $325.00
Copper pipe 22mm — 1m $22.00
Push-fit couplings x2 $18.00
Materials markup (20%) $8.00
Total $558.00
Note to Include on Emergency Invoices
Add a brief note: “Emergency service requested outside business hours. After-hours rate applies as discussed and agreed before work commenced.”
This single sentence eliminates almost every after-hours billing dispute before it starts.
Drain Cleaning and Unclogging Invoice
Drain jobs are typically flat rate. The key billing decisions are:
What to Include for Drain Jobs
- Whether CCTV camera inspection was included — bill as a separate line item
- Whether high-pressure water jetting was used — bill separately from manual unblocking
- Root cutting — bill separately with a note if roots are found
CCTV drain inspection 1 job $150.00 $150.00
High-pressure water jetting 1 job $220.00 $220.00
Root cutting — main sewer line 1 job $180.00 $180.00
Total $550.00
When the Client Doesn’t Proceed After Inspection
If you run a CCTV inspection and the client decides not to proceed with the repair, the inspection fee still applies. Bill it clearly:
CCTV drain inspection — [description of findings] $150.00
Note: Repair quote provided separately. Inspection fee applies
regardless of whether repair is authorised.
State this policy upfront when quoting — not after the inspection.
Water Heater Installation Invoice
Hot water system jobs are one of the highest-value residential plumbing jobs. The invoice needs to justify the cost clearly.
Recommended Line Items for Hot Water Installation
Remove and dispose of existing water heater $85.00
Supply and install [Brand] [capacity]L hot water
system — [model number] $1,285.00
Flexible connectors and isolation valve $45.00
Labour — installation and commissioning
3 hrs @ $115/hr $345.00
Tempering valve supply and installation $120.00
Permit fee — [issuing authority] $165.00
Total $2,045.00
Always include the make, model, and capacity of the unit installed. The client needs this for warranty claims and future servicing.
Pipe Replacement and Repiping Invoice
Large repiping jobs require progress billing — not one invoice at the end.
Progress Billing Structure for Repiping
Milestone 1 — Access, initial works, materials
delivered 25% of contract
Milestone 2 — Rough-in complete 35% of contract
Milestone 3 — Fixtures connected,
pressure tested 25% of contract
Milestone 4 — Final inspection passed,
handover 15% of contract
Each milestone invoice should reference the project name, total contract value, amount previously billed, and the current milestone amount due.
Commercial Plumbing Maintenance Invoice
Commercial maintenance contracts require a different invoice structure from residential call-out work.
Commercial Maintenance Invoice Requirements
- Purchase Order (PO) number — most commercial clients require this
- Technician name and ID — for their work order records
- Time on-site — start and finish time for labour verification
- Asset number or equipment ID — for their maintenance records
- Net 30 payment terms — standard for commercial clients
- GST/VAT number for B2B tax records
Plumbing Invoice Payment Terms
Standard Terms by Job Type
Residential Plumbing
- Due on Receipt — standard for emergency jobs and small repairs
- Net 7 — common for routine maintenance and mid-size jobs
- Net 15 — for established repeat residential clients
Commercial Plumbing
- Net 30 — standard for commercial maintenance contracts
- Progress billing — for large installations and repiping projects
Deposit Invoices for Large Plumbing Jobs
For jobs requiring significant materials upfront — water heater replacements, bathroom renovations, full repiping — a deposit invoice protects your cash flow.
Standard deposit structure for plumbing:
Project: [Description — e.g., "Full bathroom renovation —
Plumbing rough-in and fit-out"]
Total contract value: $4,800.00
Deposit required (40%): $1,920.00
Progress payment milestone 2: $1,680.00
Balance on completion: $1,200.00
The deposit covers materials before work begins. Never purchase materials for a large job without a signed quote and deposit received.
Late Payment Clause for Plumbers
Add a late payment fee statement to your invoice terms. In most jurisdictions this is legally enforceable if stated clearly:
“Invoices not paid within [payment term] will attract a late payment fee of 2% per month on the outstanding balance.”
This alone significantly reduces the number of overdue accounts — most clients will pay on time rather than incur additional charges.
Common Plumbing Invoice Mistakes
Vague Job Description
Problem: “Plumbing work — 2hrs” gives the client nothing to verify and invites disputes. Fix: Write what you actually did. “Locate and repair burst 15mm copper pipe — laundry wall” is clear, specific, and professional.
Not Separating Labour and Parts
Problem: A blended rate hides your costs and makes clients suspicious of the total. Fix: Always separate call-out fee, labour hours, and materials. Transparency builds trust and gets invoices processed faster — especially by commercial accounts payable.
Missing Emergency Rate Justification
Problem: Client disputes the after-hours rate after the fact. Fix: Add one line to the invoice notes confirming the emergency rate was agreed before work commenced. Better still, send a quick text confirmation at time of booking.
Sending the Invoice Days Later
Problem: A week-old invoice on a job the client barely remembers creates unnecessary friction. Fix: Send the invoice the same day — ideally before you leave the property. Our invoice generator works on any device so you can create and send the PDF from the job site.
Frequently Asked Questions
What should a plumbing invoice include?
Every plumbing invoice needs your business name and licence number, client details and service address, a unique invoice number and date, itemised call-out fee, labour charges, and parts used, tax on taxable items, payment terms, and accepted payment methods. For emergency jobs, add a note confirming after-hours rates were agreed before work began.
Should I use flat rate or hourly billing?
Most residential plumbers use flat rate for common jobs (drain clogs, tap replacements, toilet repairs) because clients find fixed prices easier to accept. Hourly billing works better for fault-finding, complex repairs, and commercial maintenance where the scope is genuinely uncertain. Many plumbers use both — flat rate for standard jobs, hourly for complex ones.
How do I invoice for emergency plumbing call-outs?
Charge a separate emergency call-out fee (typically $150–$250 flat or 1.5–2x your standard rate) plus labour at your after-hours rate. List these as separate line items and add a note to the invoice confirming the emergency rate was agreed before work started.
How do I handle a diagnostic fee when the client doesn’t proceed?
Bill the diagnostic or inspection fee regardless of whether the client proceeds with the repair. State this policy clearly when quoting — “inspection fee applies whether or not repair is authorised.” On the invoice, describe what was found and what was quoted for the repair, even if not approved.
What is a truck charge on a plumbing invoice?
A truck charge is your call-out or travel fee — the flat charge for attending the job regardless of time spent on repairs. The clearest way to describe it is “Service call / call-out fee” or “Travel and mobilisation fee” for commercial clients. Always show it as a separate line item with a fixed dollar amount.
How do I write a plumbing invoice for insurance claims?
Insurance companies need detailed invoices with specific information. Include the cause of damage (e.g., “burst pipe — frost damage”), a full itemised list of labour and materials, photos referenced in the invoice where possible, your licence number, and your ABN or business registration number. Contact the insurer’s claims department before invoicing to confirm their required format.
