How to Create a Construction Invoice
To create a construction invoice, start with your business and client details, add the specific services or products you delivered, then finish with totals, payment terms, and a due date. This structure works well for contractors, builders, and project-based trade teams.
1. Add the basics
Include your business name, contact information, invoice number, invoice date, due date, and the client or property details tied to the work.
2. Itemize the work clearly
- Labor, subcontractor work, and completed project phases
- Materials, equipment, and site-related reimbursable costs
- Progress billing, retainage, change orders, and deposits
3. Show totals and payment terms
List subtotals, taxes, deposits, credits, or adjustments separately, then add the total due, accepted payment methods, and any late-fee language you use.
