What Is a Contractor Invoice?

A contractor invoice is a billing document used by builders, tradespeople, construction professionals, and other contractors to charge clients for project work. It typically needs to break down costs into labour and materials separately - which is essential for clients who want to understand what they are paying for, and for contractors whose tax obligations may differ on labour versus materials.

Best practice is to invoice at agreed project milestones rather than waiting until the whole project is done. This protects your cash flow and reduces the risk of non-payment at the end of a long project.

Key Fields for Contractor Invoices

Labour breakdown - list each trade or worker type with hours and rate
Materials list - itemised with quantities and unit costs
Project address and description - to clearly identify the specific job
Subcontractor costs - if applicable, itemised separately
Retention amount - if the client withholds a percentage until completion
Milestone or progress payment reference

Frequently Asked Questions

Should I separate labour and materials on a contractor invoice?

Yes, always. Labour and materials often have different tax treatment. Separating them also makes your invoice easier to verify and reduces disputes. Many clients specifically require this breakdown for their own accounting.

What is retention on a contractor invoice?

Retention is a percentage (commonly 5 to 10%) withheld by the client from each payment until the project is fully complete and any defects are rectified. Show the full invoice amount, then deduct the retention with a note explaining it will be released after completion sign-off.

How do I invoice for variations or change orders?

Any work outside the original quote should be invoiced separately as a variation or change order. Issue a separate line item noting "Variation to contract: [description]" and the date when the variation was approved by the client.

When should I send a contractor invoice?

Invoice at agreed project milestones - not just at the end. Typical milestones include project start, after foundation or framing work, mid-project, and upon completion. Milestone billing protects your cash flow and reduces the total amount at risk if a client becomes unable to pay.
