Your payment terms decide when an invoice is due. The most common UK terms are:
This tool counts calendar days (including weekends and bank holidays) and also shows how many days are left until the due date — or how many days overdue it already is today. It is a quick estimate to help you set and chase terms; always confirm the agreed terms with your customer in writing.
Setting clear due dates is the first step to getting paid on time. If an invoice does run late, our late payment interest calculator works out what you can charge.
Net 30 means the full invoice amount is due within 30 calendar days of the invoice date. So an invoice dated 1 March with Net 30 terms is due on 31 March. Net 7, Net 14 and Net 60 work the same way with 7, 14 or 60 days. This calculator counts calendar days, not working days.
Take the invoice date and add the number of days in your payment terms. For Net 30, add 30 days; for 'due on receipt', the due date is the invoice date itself. For 'end of month' terms, the due date is the last day of the month the invoice was issued in. Enter your date and terms above and the tool does it for you.
Net 30 counts 30 days from the invoice date, so the due date moves with the invoice date. End of month (EOM) terms instead set the due date to the last day of the month the invoice was raised, regardless of which day in the month it was issued. Some businesses combine them (e.g. EOM + 30 days), but the common forms are covered here.
Yes. Standard 'Net' payment terms are based on calendar days, so weekends and bank holidays are counted. If the due date falls on a non-working day, many businesses expect payment on or before that date; you can always agree different terms with your customer in writing.
