Construction Invoice Example: Annotated Template with Line Items

TL;DR: Construction invoices should separate labor from materials, reference the contract or work order, include progress billing details if applicable, and list any change orders. Below is a fully annotated example.

Sample construction invoice

Payment Terms: Net 30 per contract. Checks payable to Hawkins Building Group LLC. Retainage of 10% held until project completion and final inspection.

Notes: Progress photos uploaded to project portal. Next milestone: drywall and insulation (estimated April 15). Change Order #2 approved by Dave Kowalski on March 12, 2026.

Field-by-field breakdown

• From: Include your contractor license number -- many states require it on every invoice.
• Project and contract reference: Ties this invoice to a specific job. Critical when you have multiple projects running.
• Billing period: Construction invoices often cover a month of work on a progress-billing schedule.
• Labor vs. materials: Always separate these. Tax rules differ (labor is often exempt; materials are taxable).
• Subcontractors: List major subs as separate lines so the client sees exactly where money goes.
• Change orders: Reference the approved change order number and the authorizing person.
• Retainage: Note the holdback percentage. This is standard in construction and reduces the current payment.
• Running totals: Show previous payments, total contract value, and remaining balance for transparency.

Common line items for construction

Variations

• Time and materials vs. fixed price: T&M invoices list actual hours and receipts; fixed-price invoices bill by milestone percentage.
• Residential vs. commercial: Commercial jobs often require AIA-format billing documents (G702/G703) in addition to a standard invoice.
• With retainage: Show the gross amount, retainage withheld, and net amount due.
• Multi-trade projects: Add a summary section grouping line items by trade (framing, electrical, plumbing, HVAC).

Tips for construction invoicing

1. Invoice at each milestone or monthly -- never wait until project completion to bill.
2. Attach lien waivers with each progress payment to protect both parties.
3. Photograph completed work before invoicing to support the billing.
4. Track change orders meticulously and invoice them as they are approved, not at the end.

FAQ

Q: Do I charge sales tax on construction labor? A: In most states, labor for real property improvements is exempt from sales tax, but materials are taxable. Some states (like Hawaii) tax everything. Check your state rules.

Q: What is retainage and how do I show it? A: Retainage is a percentage (typically 5-10%) withheld from each progress payment until the project is complete. Show it as a deduction line on your invoice.

Q: How do I handle disputed change orders? A: Never perform change-order work without written approval. Reference the signed change order document on your invoice to prevent disputes.
