Free Invoice Template for Contractors
Construction invoices get scrutinised line by line, usually by someone who has already spent more than they planned. A contractor invoice that lumps labor and materials into one number invites a fight. One that breaks out hours, materials at cost, markup, permits, and approved change orders separately tends to get paid, because there is nothing left to argue about.

How contractors usually bill
Residential work is usually a fixed contract price billed in progress draws tied to milestones — deposit, rough-in, substantial completion, final. Time-and-materials work bills labor hours at a posted rate plus materials at cost plus an agreed markup percentage. Change orders are the third stream and should never be folded into an existing line; they are separately approved work and belong on their own numbered line referencing the signed change order.
What belongs on a contractor invoice
Beyond the obvious — your details, the client’s details, a total — these are the fields that a generic invoice template leaves out and that contractors need:
- Job site address — the billing address and the work address are frequently different
- Your contractor licence number, which many states require on invoices and which clients check
- Contract or estimate number, and which draw this is (Draw 2 of 4)
- Labor hours and rate shown separately from materials
- Materials at cost with the markup percentage stated, not buried
- Change orders listed individually with their approval date
- Retainage held, if the contract provides for it, shown as a deduction
Deposits, terms, and when to invoice
Deposits of 10–33% are normal for residential work, and several states cap what a contractor may collect up front — check yours before writing the number. Progress draws are typically due on presentation or Net 10, not Net 30; the whole point is funding the next phase. Retainage of 5–10% withheld until final inspection is common on larger jobs and should be shown on the invoice as a line, so both sides are tracking the same balance.
Tax and pass-through costs
Sales tax treatment of construction is genuinely complicated and varies by state: in some, the contractor is the end consumer of materials and pays tax on purchase; in others the improvement is taxable to the owner; and some distinguish between new construction and repair. Whether you show materials at cost or with tax included changes what the client owes. Also keep lien-waiver paperwork moving in step with payments — an unconditional waiver signed before the money clears is a mistake that is hard to unwind. General information, not legal or tax advice.
Line items that prevent arguments
Each of these is a real dispute that a single line on the invoice makes impossible to have:
- "That wasn't in the quote" — a change order line with its approval date ends the conversation immediately.
- "Why did materials cost that much?" — materials at cost with a stated markup is defensible; a blended number is not.
- "We're holding the last payment" — showing retainage explicitly means the final balance is expected, not disputed.
Should a contractor invoice show labor and materials separately?
Yes. It is the single biggest reduction in payment friction available to you, it is required for many insurance and tax purposes, and in states where materials and labor are taxed differently it may be legally necessary.
How do I invoice for change orders?
As their own line, referencing the change order number and the date the client approved it. Never adjust an existing line upward — that reads as a price increase rather than additional approved work.
What is retainage and does it go on the invoice?
Retainage is a percentage the owner withholds until the job passes final inspection. Show it as a deduction on each progress invoice and invoice it as its own line at the end, so the outstanding balance is never a surprise.
