Contractor invoices aren't like other invoices. You're billing for labor and materials separately, accounting for deposits, and sometimes sending progress payments across a job that takes weeks. A generic template doesn't cover any of that.
This free contractor invoice template is set up the way contractors actually bill. Below, we'll walk through what goes on it and how to avoid the mistakes that slow down payment.

What Makes Contractor Invoices Different
Unlike service-only invoices, contractor invoices typically include both labor and materials. Some jobs require progress billing—invoicing at milestones rather than all at once. Clients often expect itemized breakdowns showing exactly where their money went.
Getting this right matters. Vague contractor invoices lead to disputes. Detailed ones protect both you and the client.
What to Include on a Contractor Invoice
Your Business Information
Company name, address, phone, email. Include your contractor's license number if your state requires it. This legitimizes your invoice and may be necessary for permits or insurance claims on the client's end.
Client Information
Client name or company, project address (if different from billing address), and billing address. For larger jobs, include a project name or job number for reference.
Invoice Number and Date
Unique invoice number and the date issued. For progress billing, consider numbering like INV-2024-001-A, INV-2024-001-B for the same project.
Job Description or Project Reference
A brief description of the overall project or a reference to the original estimate/contract. This ties the invoice to the agreed scope of work.
Labor Breakdown
Itemize labor by task or phase:
- Demolition and prep — 8 hours @ $65/hr — $520
- Framing — 12 hours @ $65/hr — $780
- Finish work — 6 hours @ $65/hr — $390
If you have a crew, you might show crew hours rather than individual hours. What matters is transparency.
Materials Breakdown
List materials with costs. You can include markup if that's your pricing model:
- Lumber (2x4, 2x6) — $342.50
- Drywall (12 sheets) — $156.00
- Hardware and fasteners — $89.00
Some contractors attach receipts. Others provide itemized lists. Either works—the goal is showing what was purchased and at what cost.
Subtotals by Category
Total labor and materials separately before combining. Clients appreciate seeing:
- Labor Subtotal: $1,690
- Materials Subtotal: $587.50
This breakdown helps them understand their investment.
Tax
Sales tax rules for contractors vary by state and project type. Some states tax materials but not labor. Others tax the whole job. Know your local requirements and show tax as a separate line.
Payment Terms
For smaller jobs, "Due on Receipt" is typical. Commercial work usually runs on Net 30. Larger residential jobs often use progress payments — something like 30% deposit, 40% at framing, 30% at completion. Whatever you choose, reference any deposit already paid and show the remaining balance.
Payment Methods
How can they pay? Check, bank transfer, card, Venmo—list your options. For larger amounts, bank transfer or check is typical. Include necessary details (account number, mailing address).
Progress Billing for Larger Jobs
For projects spanning weeks or months, waiting until completion to invoice creates cash flow problems for you and sticker shock for clients.
Progress billing solves this. You can invoice at defined milestones (foundation done, rough-in done, etc.), bill a percentage of the total contract at regular intervals, or just invoice weekly or monthly for ongoing work. The right approach depends on the job size and what you agreed to with the client.
Always tie progress invoices to work completed. If you invoice for "50% complete," be ready to show what that 50% looks like.
Handling Change Orders
Scope changes happen. When they do:
- Document the change order separately before doing the work
- On the invoice, clearly label change order items
- Reference the approved change order number
This prevents disputes over "I never agreed to that" because you have documentation.
Common Contractor Invoice Mistakes
"Kitchen remodel — $12,000" as a single line item tells the client nothing and practically guarantees they'll call you with questions. Same with leaving off your license number — some clients need it for insurance or permit paperwork.
- No reference to contract or estimate — Makes it hard for clients to verify what they agreed to
- Forgetting deposits — Show what was paid upfront and what's remaining
- Unclear tax treatment — Know your state's rules and apply them correctly
Template vs. Invoicing Software
The Excel template works well for straightforward jobs. But contractor businesses often have complexities:
- Multiple ongoing projects
- Progress billing across months
- Tracking deposits and balances
- Year-end reporting for taxes
Juggling this in spreadsheets gets messy fast. Invoicing software automates tracking, but most charge monthly — $15-30/month adds up. If spreadsheets start feeling limiting, IronBase does this for a flat $79 — no monthly fees.
Checklist
- Grab the template: English | Español
- Separate labor from materials — clients will ask anyway
- Put your license number on there if your state requires it
- Bill in stages on longer jobs so you're not floating costs for months
- Get change orders in writing before you do the work, then bill them as separate line items
- Always show what's been paid and what's still owed
A clear, itemized invoice means fewer phone calls asking "what's this charge?" and faster payment. That's really all there is to it.
