Payment due (Net 120)

What does Net 120 mean?

Net 120 is a payment term stating that the full ("net") invoice amount is due 120 calendar days after the invoice date. It's one of the most common ways businesses agree on when an invoice gets paid. Net 120 is an extended term seen in large corporate and government supply agreements. Counting starts from the invoice date unless your contract says "from receipt" or "from delivery", so spell out which one you mean on the invoice.

Early-payment discounts & late fees

You can pair Net 120 with an early-payment discount written as "2/10 Net 120" — 2% off if the client pays within 10 days, otherwise the full amount is due in 120 days. To discourage late payment, many businesses add a late fee of roughly 1.5% per month on overdue balances. State both the due date and any late-fee policy clearly on every invoice so there's no ambiguity.
