Payment due (Net 15)

What does Net 15 mean?

Net 15 is a payment term stating that the full ("net") invoice amount is due 15 calendar days after the invoice date. It's one of the most common ways businesses agree on when an invoice gets paid. Net 15 is widely used by small businesses and contractors who want predictable, twice-monthly cash flow. 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 15 with an early-payment discount written as "2/10 Net 15" — 2% off if the client pays within 10 days, otherwise the full amount is due in 15 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.
