Free Invoice Template for Contractors

A contractor billing invoice needs the job address and scope of work, an itemized breakdown of labor and materials, the payment stage or draw number if you're billing progressively, any change orders billed separately from the original contract, and your payment terms including deposit and retainage amounts. Most general contractors and subcontractors don't bill like a typical service business — you're often invoicing against a signed contract or bid, tracking partial payments across a multi-week job, and separating labor from materials so clients can see exactly what they're paying for. Getting this structure right protects you if a client disputes a charge or a job stalls halfway through.

Whether you're a solo contractor doing bathroom remodels or you run crews on multiple job sites, your invoice is the paper trail that keeps you paid on schedule. You can create a contractor billing invoice free right now and have it ready to send before you finish loading the truck.

What should be on a contractor invoice?

A contractor invoice should include the job site address, a description of the work covered by that specific invoice, itemized labor and material costs, the contract or estimate number it ties back to, and clear payment terms. Because contractor jobs often span weeks or months, each invoice should also state which phase or draw it represents so the client can match it against the original bid.

• Job details: property address, contract or PO number, and the date range the invoice covers
• Scope of work: a plain description of what was completed since the last invoice (e.g., "framing and rough electrical complete")
• Labor: hours or crew days, broken out by trade if you subcontract
• Materials: lumber, fixtures, permits, and equipment rental, listed separately from labor so markup is visible
• Change orders: anything outside the original scope, billed as its own line item with the client's approval noted
• Payment status: deposit already collected, retainage withheld, and the balance now due

How do contractors typically bill for a job?

Contractors typically bill one of three ways: a flat price for the whole job, hourly plus materials for smaller or open-ended work, or progress billing in draws tied to project milestones for larger jobs. A kitchen remodel bid at $18,000 might be split into a 30% deposit ($5,400) before work starts, a 40% draw ($7,200) at the halfway point, and the final 30% ($5,400) on completion. Smaller repair jobs are often simpler — a plumber fixing a leak might bill $85/hour plus the cost of parts, invoiced once the job is done. Many contractors also hold back 5-10% retainage on larger contracts, released only after a final walkthrough, so your invoice should show that amount as withheld rather than leave it off entirely.

What invoicing mistakes do contractors make most often?

• Lumping labor and materials together. Clients want to see what they paid for a plumber's time versus what they paid for the copper pipe — combining them invites disputes.
• Billing change orders without a paper trail. If a client asked you to add a window mid-job, get written approval before the work starts, not just before the invoice goes out.
• Forgetting to track deposits and draws. If your invoice doesn't show the running total collected against the contract, both you and the client lose track of what's actually owed.
• Skipping lien rights language. Depending on your state, invoices for construction work may need to reference mechanic's lien rights — check your state's requirements, since this varies widely.
• No documented payment terms. Late payments are common in construction. Spell out your due date and any late fee up front — see our sample invoice terms for freelancers and small businesses for wording you can adapt.
