The due date is simply the invoice date plus the number of days in your payment terms. Net 30 terms mean payment is due 30 days after the invoice date, Net 60 means 60 days, and so on.
For example, an invoice dated July 28, 2026 with Net 30 terms is due August 27, 2026.
Net 15, Net 30, Net 45, and Net 60 are the most common terms, with Net 30 being the default in most B2B invoicing. Some businesses also offer early-payment discounts, like '2/10 Net 30' meaning a 2% discount if paid within 10 days, otherwise the full amount is due in 30.
Enter the exact number of days from your payment terms, for example 45 for Net 45 or 7 for weekly terms. The calculator adds that many calendar days to the invoice date.
No, it adds calendar days, not business days, which matches how most standard payment terms (Net 30, Net 60, etc.) are defined.
