Invoice Late Fees: How to Set Up and Charge Late Payment Penalties

Charging a late fee is the most effective way to encourage clients to pay on time — but you need to set it up correctly and communicate it clearly.

How much to charge

1.5% per month is common and legal in most jurisdictions
Some states cap late fees (e.g., 10% maximum in certain cases)
Flat fees ($25-50) work for larger invoices

How to set it up

State the late fee policy clearly on every invoice (in the Notes/Terms section)
Include it in your contract or service agreement upfront
Apply it consistently — do not let one client slide while charging another
Send a polite reminder before applying the fee

Sample wording

"A late fee of 1.5% per month will be applied to invoices not paid within 30 days of the due date."
