Choose the invoice date and the payment terms you agreed. The calculator returns the due date and how many days that is from the invoice date, so it is clear on the invoice and on any reminder.
How payment terms set the due date
- Net terms (Net 7, Net 30, ...)
- The number is the days allowed to pay from the invoice date. Net 30 dated 1 June is due 1 July.
- Due on receipt
- Payment is expected immediately, so the due date is the invoice date itself.
- End of month
- Payment is due at the end of the invoice month, or the end of the following month for end-of-next-month terms. Common in many European markets.
Due date FAQ
What does Net 30 mean?
Net 30 means the full amount is due 30 calendar days after the invoice date. Net 15 and Net 60 work the same way with 15 or 60 days.
How do I calculate an invoice due date?
Add the number of days in your payment terms to the invoice date. For end-of-month terms, use the last day of the relevant month. The calculator handles both.
What are good payment terms for a small business?
Shorter terms get you paid sooner. Net 14 or Net 7 is common for freelancers, while Net 30 is a frequent default for larger clients. Pick what your cash flow needs and state it clearly on the invoice.
Do weekends and holidays count?
This calculator counts calendar days. Some contracts shift a due date that lands on a weekend or public holiday to the next working day; check what you agreed.
