How the calculation works

Most payment terms count calendar days from the invoice date. So an invoice dated March 1 with Net 30 terms falls due on March 31. Saturdays, Sundays and holidays are included in the count unless the terms exclude them.

Frequently used payment terms

• Due on receipt: the invoice is payable straight away, on its issue date.
• Net 7, Net 10, Net 15: the customer has 7, 10 or 15 days from the invoice date to pay.
• Net 30: a widely used term; payment is due 30 days after the invoice date.
• Net 45, Net 60, Net 90: extended terms that give the customer 45, 60 or 90 days.
• EOM (end of month): payment falls due on the last day of the invoice month.
• Net 30 EOM: due 30 days after the last day of the month the invoice is dated in.

The exact meaning of EOM terms can differ between businesses, so check the wording of your agreement.

Weekend due dates

If the due date is on a weekend, some businesses count the following working day as the due date. With the weekend box ticked, a due date on Saturday or Sunday is shifted to Monday.
