How the due date is worked out

In most cases, the days in a payment term are calendar days counted from the invoice date. Take an invoice dated March 1 on Net 30: it is due on March 31. Unless the contract states otherwise, weekends and holidays are counted like any other day.

Common payment terms

• Due on receipt: payment is expected on the day the invoice is issued.
• Net 7, Net 10, Net 15: the due date is 7, 10 or 15 days after the date on the invoice.
• Net 30: due 30 days after the date on the invoice, one of the most familiar terms.
• Net 45, Net 60, Net 90: payment is due 45, 60 or 90 days after the invoice date.
• EOM (end of month): the invoice is due on the final day of the month it is dated in.
• Net 30 EOM: payment is due 30 days after the end of the month in which the invoice is dated.

EOM wording is not used the same way by everyone, so it is worth checking your agreement.

If the due date is a Saturday or Sunday

Some businesses treat the next working day as the due date when it lands on a Saturday or Sunday. Switch on the weekend option and a Saturday or Sunday due date moves to Monday.
