Net 30
Net 30 is a payment term that generally makes the full invoice amount due 30 calendar days after an agreed starting date, commonly the invoice date. It does not usually mean 30 business days. Because contracts and local practices can differ, show the calculated due date on the invoice instead of relying on the shorthand alone.
Why this matters when you invoice
Net 30 gives a customer time to process an invoice while giving the seller a defined payment deadline. The term is most useful when the starting date and resulting due date are explicit.
Where it appears on an invoice
Write Net 30 in the payment-terms field and show the corresponding calendar date in the due-date field. Put payment instructions and the required reference nearby.
Net 30 example
If the agreed starting date is the invoice date, an invoice dated 3 September 2026 with Net 30 terms is due on 3 October 2026.
Common mistakes
- Treating Net 30 as the end of the following month.
- Counting 30 business days instead of calendar days without an agreement.
- Assuming the start is always the invoice date.
Put the term into practice
Use the calculator to turn the agreed payment term into a calendar date, then copy the reviewed date into your invoice.

Frequently asked questions
Does Net 30 mean 30 business days?
Usually it means 30 calendar days, but the agreement should remove doubt and the invoice should show the resulting date.
Is Net 30 the same as due at the end of next month?
No. They can produce different dates. Use the wording actually agreed and display the calendar due date.
