Construction Invoice Template for Building Contractors

Construction of Buildings · NAICS 236 · Construction Invoice

A construction invoice for building contractors is more than a request for payment—it's a legal document that tracks progress, documents lien rights, and ensures cash flow on commercial and residential projects. Unlike generic invoices, construction invoices must align with AIA G702/G703 forms, include retainage, and often require lien waivers. This tool helps you create a professional, industry-standard invoice that clearly communicates the work completed, the amount due, and the payment terms, reducing disputes and speeding up payment.

Frequently asked questions

What is retainage and why is it on my invoice?

Retainage is a percentage (usually 5-10%) withheld from each progress payment to ensure the contractor completes the project. It is typically released upon substantial completion or final acceptance.

Do I need to include a lien waiver with my invoice?

Many owners and lenders require a lien waiver before releasing payment. A conditional waiver upon payment is common for progress payments, while a final unconditional waiver is used for the final payment. Check state law for specific requirements.

Can I use this invoice for residential and commercial projects?

Yes, the template is flexible for both. However, residential projects may have additional requirements like a Notice to Owner in some states (e.g., Florida). Always verify with local regulations.
