What goes on a plumbing invoice
●Call-out fee. Fixed; covers travel + first 30 min on-site.
●Standard labour (per hour). Typically billed in 15-min increments after the first hour.
●Emergency / out-of-hours rate. 1.5× or 2× standard. Disclose before dispatch.
●Parts & fittings (with markup). Pipes, valves, washers, fittings — itemised.
●Major equipment (boilers, pumps). Quote separately; invoice as installed line.
●Disposal / waste removal. Old units, debris — labour + tip fee.
How plumbers set up their billing
Reactive call-outs: pay-on-completion via card, or 7-day invoice.
Boiler installs and bathrooms: deposit + completion, or 50/50 split.
Always note the work address on the invoice if different from the bill-to address — landlords often pay for tenant addresses.
Tax notes
Materials are normally taxable. In some jurisdictions, energy-efficiency installs (heat pumps, condensing boilers) qualify for reduced rates — check before invoicing.
Frequently asked questions
How do I charge for emergency call-outs?
Set a clearly-published emergency rate (often 1.5× or 2×) and confirm it with the customer before dispatch. Show it on the invoice as 'Emergency rate (out-of-hours)' so it's never a surprise.
Should the invoice list parts at cost or marked up?
List the marked-up price — it's industry-standard and covers your time sourcing and your liability on parts. Some plumbers itemise cost + markup % for transparency.
Do I need to invoice for diagnostic time?
Yes — even for 'we couldn't find the leak.' Bill call-out + diagnostic labour. The customer is paying for your skill, not just the fix.
How do I bill landlords vs tenants?
Bill the party named on the work authorisation (usually the landlord or letting agent). Put the property address as the work address; bill-to is the landlord. Reference the property for the landlord's records.
A sample plumbing invoice
Realistic, copy-and-paste-ready line items plumbers typically use. The figures below are ballpark for a mid-cost market, so adjust them to whatever your area supports.
●Call-out fee (travel + first 30 min on-site): $85
●Standard labour, 1.5 hrs @ $95/hr (billed in 15-min increments after first hour): $142.50
●Emergency out-of-hours surcharge (Saturday call, 1.5× base rate): $71.25
●Parts — 3/4" copper pipe, two isolating valves, PTFE tape (cost + 25% markup): $48.75
●Boiler condensate drain reroute (materials + 1 hr labour): $135
●Disposal of old immersion heater (tip fee + labour): $35
●Photo report of completed work (emailed within 24 hr): no charge
Notes: All work guaranteed for 12 months. Manufacturer warranty applies to parts. Diagnostic call-outs payable in full even if no fault found. Card and BACS accepted; no fee for either.
When the money actually shows up
Reactive call-outs to homeowners pay fastest — most settle by card on the doorstep before you've packed up the van. Anything you have to invoice and wait on is where the cash-flow problem lives. Letting agents and property managers are the slowest payers in the trade: Net 30 is the contract, Net 45-60 is the reality, and the chase email at day 35 is part of the job.
For new boiler installs or full bathrooms, run a 30% deposit on signed quote, 40% on first fix (tested-tight stage), 30% on commissioning. Never leave more than 30% riding on the final invoice — once the water's flowing the urgency disappears. For landlord call-outs, get the work-authorisation in writing before dispatch; verbal 'just fix it and bill me' is how plumbers get stuck chasing letting agents for six weeks.
Five invoicing mistakes that slow down your pay
●Not photographing the leak before you touch anything. Insurers and landlords pay faster against a photo than a description. A 30-second iPhone snap on arrival saves three emails and a week of 'can you describe what you saw?'
●Lumping parts into 'materials' without a line per item. Customers dispute round totals. Itemise the copper, the valves, the PTFE, the bracket — even at $4 each. Disputes drop sharply when the invoice reads like a receipt.
●Forgetting the call-out fee on follow-up visits. If you came back for the same job, the second visit still costs you fuel and a van slot. Disclose the return-visit policy up front; don't pretend it's free.
●Billing the tenant when the landlord is liable. Tenant pays for misuse (blocked toilet from wipes). Landlord pays for system failure (failed valve, burst stack). Get the work-authorisation signed by the right party or you invoice the wrong name.
●Quoting in 'an hour or so'. Plumbers who quote vague estimates lose disputes on every line over the magic number. Quote a range and disclose the trigger that pushes you into the upper end (concealed pipework, suspected lead solder, etc.).
US tax notes for plumbers
Sales tax on plumbing work splits unevenly by state. In Texas, residential repair labour is non-taxable but the parts are; in California, only the materials carry sales tax; in New York, capital-improvement work (a new bathroom) is exempt under a Form ST-124 from the homeowner, but a like-for-like repair is fully taxable. Get the exemption certificate on file before invoicing, or you eat the 8-9% out of your margin when the audit comes.
On the federal side, every business client paying you more than $600 in a year should issue a 1099-NEC — ask for the W-9 on the first job, not the last. Self-employment tax runs 15.3% on top of income tax, and quarterly estimated payments avoid the underpayment penalty. Deductibles that real plumbers miss: van depreciation under Section 179, tool depreciation, continuing-ed for journeyman renewal, and the personal-protective-equipment line (boots, gloves, masks, eye protection) which goes against ordinary business expenses.

More questions plumbers bring up
Do I bill for diagnostic time if I can't find the leak?
Yes. The customer is paying for skill, not just the fix. List it as 'Diagnostic call-out and investigation — 1.5 hr' with a one-line note on what you ruled out. Refusing payment for honest diagnostic work is the customer's fastest path to a Better Business Bureau complaint they'll lose.
How do I invoice when I've installed parts the customer supplied?
Don't warranty parts you didn't source. Add a line: 'Installation of customer-supplied parts — labour only, no parts warranty (manufacturer warranty applies).' Sign it, photograph the box and serial number, attach the photo to your records. Saves you from the 'it leaked, you fix it free' conversation in month 7.
Should my hourly rate change for new construction vs service calls?
Yes — they're different jobs. New-construction rough-in is steady, predictable, often 8-hour days with the GC's schedule pulling you along. Service calls are unpredictable, often dirty, and chew through a half-day for two billable hours. Most plumbers run service at 30-50% above new-construction labour. Don't quote them blended.
What's a fair late-payment fee structure?
Most states cap statutory late fees at 1.5% per month (18% APR). Put 'Late payment: 1.5% per month or $25 minimum, applied after 30 days' in your terms block. Don't activate it on the first late invoice — the goodwill of waiving it earns more than the $25 in repeat work.
