Frequently asked questions

What is retainage on a construction invoice?

Retainage is a percentage (typically 5-10%) that the client withholds from each progress payment until the project is complete. It protects the client against defects or unfinished work. Your invoice should clearly show the retainage amount deducted from the gross total.

Why do I need a lien rights notice on my invoice?

In many states, including a notice on your invoice helps preserve your right to file a mechanic's lien if you aren't paid. It puts the client on notice that the work is protected by lien laws, which can encourage timely payment.

Can I use this invoice for progress billings?

Yes, the invoice format supports progress billings. Simply list the work completed during the billing period, and if retainage applies, it will be calculated automatically based on the percentage you enter.
