Invoicing Challenges for Construction Companies

AIA-Style Progress Billing

Many commercial projects require AIA G702/G703 formatted applications for payment. These involve schedule-of-values breakdowns, percentage-complete tracking, and cumulative billing — far beyond a simple invoice.

Subcontractor Cost Pass-Through

General contractors bill for their own work plus subcontractor costs. Each sub’s charges need to be clearly represented on the invoice so the owner can track costs by trade and verify the work was completed.

Lien Waiver and Compliance Requirements

Many states require lien waivers to accompany each payment application. Your invoicing workflow needs to account for collecting and submitting these documents alongside every billing cycle.

Construction Companies Invoicing Tips

Use a Schedule of Values

Break the total contract amount into a schedule of values by trade or phase. Each invoice shows the percentage complete and amount billed for each line item, giving the owner full cost visibility.

Track Retainage Cumulatively

Show retainage withheld on each invoice and maintain a running total. When the project reaches substantial completion, submit a separate invoice to release the accumulated retainage.

Separate GC Fees from Sub Costs

Clearly distinguish your general conditions and overhead from subcontractor pass-through costs. This transparency satisfies owner audits and streamlines payment approvals.

Reference Change Orders by Number

Every approved change order should have its own line in the schedule of values. Reference the CO number, date approved, and amount so the owner can reconcile each change against their records.

Frequently Asked Questions

What is AIA-style billing in construction?

AIA billing refers to the American Institute of Architects’ standard payment application forms (G702 and G703). They require a schedule of values, percentage-complete tracking, retainage, and cumulative billing. Many commercial projects mandate this format.

How does retainage work on construction invoices?

Retainage is typically 5-10% withheld from each progress payment as security for project completion. It is shown as a deduction on each invoice and released after the owner accepts the completed work, often at substantial completion.

How do I bill for subcontractor work as a general contractor?

Include each subcontractor’s work as a line item in your schedule of values. Show the subcontracted amount, percentage complete, and amount due this period. Some owners require you to attach sub invoices as backup documentation.

Do I need lien waivers with my construction invoices?

In most US states, yes. Conditional lien waivers are submitted with each payment application, and unconditional waivers are submitted after payment is received. Check your state’s requirements — failure to comply can delay payment.
