Contractor invoice template for stage payments, materials and variations
Invoice checklist
What a contractor invoice should show
The job address
Separate from the client's billing address. A client with more than one property, or a landlord paying for work at a tenant's address, cannot approve an invoice that does not say which site it is for.
The original quote reference and value
Every invoice in the sequence should reference the quote it belongs to. This is what turns a series of invoices into something that can be checked rather than a series of separate requests for money.
Which stage this invoice covers
Name the stage and its position: "Stage 2 of 4 – first fix complete". Then show the amount billed to date against the quoted total. Those two numbers together answer almost every question a client would otherwise ask.
Labour and materials on separate lines
Clients check materials against what they can see delivered and price independently. Combined figures invite a conversation about the whole invoice; separated ones limit any query to a single line.
Variations, individually
Each change from the original quote gets its own line, with what was asked for and when. Variations agreed verbally on site and then billed without explanation are the single biggest cause of disputed trade invoices.
Tax treatment for construction work
Construction is treated differently from general services in many tax systems, including reverse-charge arrangements between contractors. Confirm which applies to your work in your own country, and make sure the invoice states it.
Getting paid
How to bill as a contractor
Advance for materials
Where the client funds materials up front, invoice it as an advance against the job rather than as a separate sale, and show it on every later invoice as an amount already received. The client then always sees the full picture.
Stage payments
Tie each stage to something visible on site rather than to a date. "On completion of first fix" can be verified by anyone standing in the room; "at four weeks" cannot, and gets argued about when the schedule slips for reasons outside your control.
Day work and extra labour
Show the dates, the hours and the rate. Day work billed as a lump sum weeks later is very hard for a client to verify and therefore very easy to postpone.
Retention
If the contract holds back a percentage until completion, show the gross amount, the retention deducted and the net now due. Retention that is silently omitted looks like an error in the client's favour and will be treated as one.

Corporate
A fully bordered grid, which is the clearest way to present many lines of labour, materials and variations together.
Bold
The heaviest total in the set. Built for an invoice that is printed and handed over on site rather than emailed.
Column
A coloured sidebar with details stacked in one readable column, for a client who scans for a single figure.
Avoid these
Contractors and trades invoice mistakes that delay payment
Billing a variation without a written record
If it was agreed on site, send a short message confirming it the same day. That message is what makes the line on the invoice defensible.
No running total against the quote
Without it, the client has to open every previous invoice to work out where they are, and most will simply wait until it is convenient.
Invoicing only at the end of a long job
It concentrates all the risk at the point where you have the least leverage. Stage billing protects cash flow and keeps any dispute small enough to resolve.
Handwritten invoices for larger work
They are frequently rejected by commercial clients and letting agents, and they make a variation impossible to prove months later.
FAQ
Contractors and trades invoice template: frequently asked questions
How should a contractor structure stage payments?
Tie stages to verifiable milestones on site, agree them in the quote before starting, and invoice each one as it completes. Three or four stages suits most domestic jobs; long commercial work is usually billed monthly against measured progress instead.
Should materials be marked up on the invoice?
That is a commercial decision, but whatever you decide should be consistent with what the quote said. A markup that was implied in the quote and then itemised on the invoice is where clients feel misled, even when the total is exactly what they agreed.
Can I show an advance for materials in Invooza?
Yes. Turn on advance tracking in Rules, record the advance with the date it was received, and every template prints it under the total with the balance still owed.
What do I do if the client disputes a variation?
Refer to the written confirmation you sent when it was agreed, and keep that variation as its own line rather than rolling it into the stage total. A dispute over one line does not have to hold up payment of the rest of the invoice.
