Send the billing record
Send the final charges, delivery reference and due date to the customer, then reconcile payment against the invoice number.
A plumbing repair invoice has to explain work the customer mostly did not see: where the leak was, how much pipe was cut out and whether the system held pressure afterwards. Insurers and landlords often ask for exactly those facts before they pay. This template puts the leak detection, the pipe replacement and the flow test on separate lines, so the customer can match each one to what happened in the wall or under the floor.
Fields to prepare
- Deliverables and line items
- Leak detection, Pipe replacement, Water flow testing: record the quantities actually supplied and the service period.
- Leak detection
- Name the method you used, such as thermal imaging or acoustic detection, and where the leak was found.
- Pipe replacement
- Give the length, diameter and material of the new pipe, and whether opening and closing the wall is included.
- Water flow testing
- Write the test pressure and how long the system held it; an insurer may ask for this figure.
- Site and measured quantities
- Record the site, work zones, areas, lengths or counts, and access hours.
- Materials and work stages
- Specify materials, labor, removal, disposal and making-good allowances, and completion criteria for each stage.
- Scope to agree
- Record leak locations, replacement pipe lengths and materials, flow-test sections and any wall reinstatement.
Before sending
- Does “Leak detection” show the quantity actually supplied, not the quantity first quoted?
- Is “Pipe replacement” charged at the rate the customer agreed to, with any change approved?
- Is “Water flow testing” finished and accepted, or does it belong on a later invoice?
Show 3 more
- Agree how quantity changes following measurement or drawing revisions will be approved.
- Confirm client-supplied materials and work that other contractors must finish first.
- Match completed work to the order or approval record, and confirm the payment due date and amounts already received.

Frequently asked questions
Can I invoice a leak search that found no leak?
Yes, if the call-out was booked as a search. Say which areas you checked and with what result, so the customer knows what has been ruled out.
What does the customer need for an insurance claim?
Usually the invoice with the cause of the leak in plain words, a few photos and the pressure-test result. Ask the customer what their insurer wants before you send it.
How is the sales tax worked out on this invoice?
The worked example above uses an example rate of 8%: $792.00 on a net amount of $9,900.00, for a total of $10,692.00. The editor recalculates all three when you change a quantity, a price or the country.
How should I number invoices?
Use one unbroken sequence per business, never reuse a number, and issue a credit note rather than deleting an invoice you have already sent.
Can I download it as Excel, Word or PDF?
Yes. A PDF needs no account: fill in the template and use Print / PDF. The Excel and Word files download from this page with a free account, and the spreadsheet keeps its formulas, so changing a quantity updates the tax and the total.
