Free Invoice Template for Contractor
Contractors need invoices that clearly break down labor costs, materials, and project phases. Whether you're in construction, home improvement, or specialized trades, a detailed invoice protects both you and your client. Our free contractor invoice template is designed specifically for the contracting industry with support for itemized labor hours, material costs, permit fees, and milestone-based billing. Contractors often work on multi-phase projects that span weeks or months. Progress billing — invoicing at each project milestone — keeps cash flow steady and reduces the risk of non-payment. Include a clear description of completed work, reference the original estimate or contract number, and list any change orders separately. Always document material costs with quantities and unit prices so clients can verify charges. Professional invoices also help when filing taxes, tracking expenses, and resolving disputes.

Frequently Asked Questions
How do contractors bill for materials?
List each material with quantity, unit price, and total. Some contractors add a markup (10-20%) to cover procurement time. Always keep receipts and offer to share them with clients for transparency.
What is progress billing for contractors?
Progress billing means invoicing at project milestones (e.g., 30% at foundation, 30% at framing, 40% at completion). This maintains cash flow and reduces risk for both contractor and client.
Should contractors charge for estimates?
Small jobs typically get free estimates, but complex projects may warrant a paid estimate ($50-$500) that's credited toward the project if hired. Include this policy on your invoices and contracts.
