Make the payment-term convention explicit
Net terms are a length, not a calendar by themselves
Select the invoice date and the number of days stated in the payment terms. Net 7, 15, 30, 60 and 90 are shortcuts; a custom term accepts 0–365 days. Confirm from the agreement whether those days are calendar days or business days rather than inferring the rule from the shortcut name.
Day zero and weekend results
The invoice date is day zero. In calendar-day mode, every following date counts, including weekends and holidays. The calculated date is shown literally; a Saturday or Sunday is not automatically moved to Monday.
Business-day mode
When enabled, the tool counts Monday to Friday and optionally excludes country-wide public and bank holidays from the source calendar. It does not include all regional or municipal holidays, banking cutoff times or settlement delays.
Due date is different from receipt of funds
A payment initiated on a due date can arrive later depending on its method. The tool calculates the stated interval and does not decide a contract’s weekend adjustment, late charges, early-payment discount or date of legal receipt. Use the displayed date with the actual payment terms.
Two payment-term examples
| Invoice and mode | Literal due date |
|---|---|
| July 1, 2026; Net 30 calendar days | July 31, 2026 |
| July 17, 2026; Net 30 calendar days | Sunday August 16, 2026; no automatic shift |
| July 17, 2026; 1 business day; no holidays | Monday July 20, 2026 |
Frequently asked questions
Does a Sunday result automatically become Monday?
No. Calendar-day mode shows the literal result; apply any adjustment specified by the agreement separately.
Can I use a zero-day term?
Yes. Zero keeps the invoice date in either counting mode.
Does copying the date create an invoice?
No. The copy action only copies the calculated date.
