Contractor Invoice Template: Free Guide & What to Include
Contractors need invoices that clearly separate labor, materials, and change orders. A sloppy invoice leads to payment disputes and cash flow problems.
What Makes a Contractor Invoice Different
Unlike a simple service invoice, contractor invoices often include progress billing, retainage, and detailed line items tied to a scope of work or contract number.
Essential Fields for Contractor Invoices
- Contractor license number (if required in your state)
- Project name and site address
- Contract or PO reference number
- Labor hours and rates by trade or worker category
- Materials with quantities and unit costs
- Change order references for any scope additions
- Retainage percentage if applicable
- Payment schedule (deposit, progress, final)
Labor vs Materials Breakdown
Always itemize separately. Clients and accountants need this split for tax and insurance purposes. Example:
- Framing labor — 40 hrs × $65/hr = $2,600
- Lumber and fasteners — $1,840
- Change Order #2 — additional electrical rough-in — $950
Payment Terms for Contractors
| Project Size | Recommended Terms |
|---|---|
| Under $5,000 | 50% deposit, 50% on completion |
| $5,000–$50,000 | Progress billing at milestones |
| Over $50,000 | Monthly progress + retainage |
Common Mistakes to Avoid
- Not referencing the original contract or quote
- Missing permit or inspection dates on progress invoices
- Forgetting to deduct previous payments on progress bills
