What is a payment due date?

The payment due date is the last day to pay an invoice. It comes from the invoice date and the payment terms printed on the invoice, such as Net 30, which gives the customer 30 days to pay.

Common payment terms

  • Due on receipt: pay right away, the due date is the invoice date
  • Net 7, Net 10, Net 14, Net 15, Net 30, Net 45, Net 60, Net 90: pay within that many days of the invoice date
  • End of month (EOM): pay by the last day of the month the invoice is dated in
  • Net 30 EOM: pay within 30 days after the end of the invoice month, so an invoice from October 5 is due on November 30
  • Custom: any number of days after the invoice date

Tool description

Enter the invoice date and pick the payment terms. The tool shows:

  • The due date, with its weekday
  • The days to pay, counted in calendar days from the invoice date
  • How far the due date is from today: due in a number of days, due today, or overdue

Due dates on a weekend

Many businesses don't process payments on Saturdays and Sundays. Pick Move to the next Monday or Move to the previous Friday to move a due date that falls on a weekend, and the tool tells you when it did. A due date never moves before the invoice date.

Example

An invoice dated Tuesday, October 20, 2026, with Net 30 terms is due on Thursday, November 19, 2026. With Net 30 EOM terms the same invoice is due on Monday, November 30.

Good to know

The tool counts calendar days and knows weekends, but not public holidays, so check the date when a holiday is near. Your contract or local law may also set other rules for late payments.
