How to fill out an electrician invoice
Follow these steps after every job to get paid faster and stay on the right side of IRD.
Fill in your business details
Add your trading name, GST number, EWRB registration number, address, phone, and email at the top. If you trade as Crestline Electrical Ltd, use that - not your personal name. Your EWRB number confirms to the customer that the work was carried out by a licensed person.
Set the invoice number and dates
Use a sequential number - INV-0083 after INV-0082. The invoice date is today. Set a due date (14 days is standard; 7 days is reasonable for smaller residential call-outs). Consistent numbering helps if you ever need to prove payment history to IRD or a disputes tribunal.
Add the customer details
If the buyer is GST registered, invoices of $1,000 or more need their name plus one identifying detail - address, phone number, email address, trading name, NZBN, or website. Do this on every job - it looks professional and removes any ambiguity about who the invoice is for if a dispute arises later.
List every line item separately
Don't lump everything into one number. Split call-out fee, labour hours × rate, each material or fitting, any CoC fee, and any after-hours surcharge. Example: "Labour - EV charger install: 3.5 hrs × $125 = $437.50". Detailed descriptions get paid faster and reduce back-and-forth with the customer.
Reference the CoC if you issued one
For prescribed electrical work, you must issue a Certificate of Compliance. Reference the CoC number in the job description or notes - for example, "CoC No. CE-2026-07341 issued". If you charge a separate CoC fee, add it as its own line item. This keeps the paperwork consistent and is useful if the customer ever sells the property.
Calculate GST and show it clearly
Multiply your subtotal by 0.15 to get the GST amount. Show subtotal, GST, and total as three separate lines - never just a single total. Use the free Invio GST calculator at /gst-calculator-nz if you want a quick check before sending.
Add your bank account details and send
Include your bank account number and ask the customer to use your invoice number as the payment reference. Then send it the same day. "Pay to: Crestline Electrical Ltd 02-0741-0298340-00, Ref: INV-0083" is all you need. If you use Invio, hit send from your phone before you pull out of the driveway.
Common electrician invoice mistakes
These mistakes slow payment, create disputes, or put you offside with IRD. Easy to fix once you know them.
Missing EWRB registration number
e.g. Invoice with no licence reference
Add your EWRB number to the invoice header. Commercial clients often require it before approving payment, and it confirms your legal right to do the work.
No CoC reference on prescribed work
e.g. "EV charger installed - $1,200" with no CoC mention
If you issued a Certificate of Compliance, reference it on the invoice. Add "CoC No. CE-2026-07341 issued" in the job description or notes. Customers may need this for their records or insurance.
Wrong or missing GST
e.g. "Total: $2,302" with no GST line
Show subtotal, 15% GST, and GST-inclusive total as three separate lines. Commercial customers need this to claim GST back from IRD.
Materials and labour lumped together
e.g. "Switchboard upgrade - materials and labour: $1,800"
List parts separately from labour. Many customers - especially commercial ones - will not approve payment until the invoice is properly itemised. It also protects you if there's a warranty question later.
No bank details on the invoice
e.g. Invoice sent with no payment instructions
Always include your bank account number and ask for the invoice number as the payment reference. No bank details means slow or lost payments.
Sending days after the job
e.g. Invoice sent a week after the switchboard work
Send it the same day. Every day you wait, the chance of a prompt payment drops. If an invoice is already late, see our guide on chasing overdue invoices at /chase-overdue-invoices-nz.
What goes on the lines, and what it usually costs
The lines an electrical invoice tends to have, in the three groups they fall into.
Labour and time
Priced per hour, or per call-out
Standard labour rate
Per hour, on site
$95 - $150/hr
Ex GST. Auckland and Wellington run higher; regional NZ lower.
After-hours or weekend labour
Agree it before you start
$180 - $240/hr
1.5x to 2x your standard rate. State it clearly in the quote, then match the invoice to what was agreed - a $120/hr sparky charging $180-$240/hr is the live example this range is drawn from.
Call-out fee
Per visit, covers travel
$60 - $120
Charged per visit to cover travel and mobilisation. Some sparkies waive it for regulars.
Materials
At cost plus your markup
Materials markup
On top of supplier cost
Cost + 20 - 30%
Covers handling, warranty, and supplier runs. List parts at your sell price - you don't need to show your cost.
Compliance and disposal
The lines other trades do not have
Certificate of Compliance fee
For prescribed electrical work
$45 - $80
Some sparkies include it in labour; others list it separately.
Disposal or waste fee
Old switchboards, cable, fittings
$30 - $60
For removing anything that needs safe disposal.
Indicative GST-exclusive ranges for 2026, to sanity-check a line you have not priced before. GST itself is 15% on top of the subtotal once you are registered - use the free GST calculator to check. They are not a price guide and not advice on what to charge: rates vary by region, by job, and by who is holding the ladder.
Why Invio beats Word and Excel for sparkies
Templates are a fine starting point. But most electricians move to proper software once they're running 10+ jobs a month.
Invoice from your van on site
Fill in labour hours, materials, and call-out fee before you drive off. No paperwork to chase at the end of the week, and the customer gets the invoice while the job is still fresh.

What an electrician's invoice carries that the others do not
Every NZ trade invoice needs the same GST basics. Past that, the paperwork splits by trade - here is what is specific to electrical work.
EWRB
A registration number
Electricians carry an EWRB number. Builders and carpenters carry an LBP number instead, for restricted building work. Plumbers are registered with the Plumbers, Gasfitters and Drainlayers Board and hold an annual practising licence for restricted work, and painters and landscapers have no equivalent at all.
CoC No. CE-2026-07341
The Certificate of Compliance reference
Only electrical work needing a CoC carries this line. It is a separate document, but its reference on the invoice keeps the paper trail in one place if the property ever needs it again.
$80.00
The call-out fee, on its own line
Charged per visit and listed apart from labour, not folded into the hourly rate where it reads as a markup nobody can see.
3.5 hrs
Labour in hours, to one decimal
Not read as half a day. Hours at a stated rate is the line a customer checks first, on an electrician's invoice or any other trade's.
