Preparation guide
Example workflow
Confirm scope and quantities
Example: reconcile the approval and work record for "Distribution board replacement" to establish the quantity for this invoice.
Record delivery and acceptance
Check completion for every line, including "Insulation resistance measurement". Confirm completed quantities, site photos, agreed test results and any remaining remedial work.
Send the billing record
Send the final charges, delivery reference and due date to the customer, then reconcile payment against the invoice number.
Electricians send this invoice after a job is finished and tested. It fits a typical domestic or small commercial job: replacing the distribution board, adding outlets and measuring the insulation resistance of the circuits before handing back. The testing line sets it apart from a general contractor’s invoice, because the client, a landlord or an insurer may later ask for the results; quoting the test report number on the invoice ties the payment to that record.
Fields to prepare
- Deliverables and line items
- Distribution board replacement, Additional outlets, Insulation resistance measurement: record the quantities actually supplied and the service period.
- Distribution board replacement
- Give the board’s make or rating and number of circuits, and put the parts either in this line or on lines of their own, never both.
- Additional outlets
- Enter the number of outlets fitted as the quantity and note the rooms, so the client can count them on a walk round.
- Insulation resistance measurement
- Bill the test per installation or per circuit, as you priced it, and add the test report number to the description.
- 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
- Link distribution-board specifications, added outlet counts and the tested circuits to measurement records.
Before sending
- Does “Distribution board replacement” show the quantity actually supplied, not the quantity first quoted?
- Is “Additional outlets” charged at the rate the customer agreed to, with any change approved?
- Is “Insulation resistance measurement” 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.
Worked example with sample figures
The figures below are invented to show how the template adds up: 3 lines in USD, with an example tax rate of 8%.

| Distribution board replacement | 12 × $750.00 | $9,000.00 |
| Additional outlets | 8 × $650.00 | $5,200.00 |

| Subtotal | $16,450.00 | |
| Sales tax (8%) | $1,316.00 | |

What the document must show
The details an invoice has to show, and why each one matters, are set out in the guide below.
The sales tax depends on where the work is supplied, so set the rate that applies to your customer before sending.

Frequently asked questions
Should materials be listed apart from labor?
It helps when the board or cable cost was large, or when the client supplied some parts. List the main components with quantities and keep labor per task, so a client who bought their own fittings can see they were not charged for them.
What if testing finds a fault in a circuit that was not part of the job?
Do not bill a repair nobody ordered. Record the fault in the test report and the invoice notes, recommend the remedial work and send a quotation for it, so the client decides before any further work is done.
Can I invoice before the test report is ready?
You can, but many clients hold payment until they have the report. If it follows a few days later, write on the invoice when it will be sent, or wait and send both together so payment is not delayed by a missing document.
How is the sales tax worked out on this invoice?
The worked example above uses an example rate of 8%: $1,316.00 on a net amount of $16,450.00, for a total of $17,766.00. The editor recalculates all three when you change a quantity, a price or the country.
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.
