How invoice due dates are calculated

For standard Net payment terms, add the specified number of calendar days to the invoice date.

  • Net 15 = invoice date + 15 days
  • Net 30 = invoice date + 30 days
  • Net 60 = invoice date + 60 days
  • Net 90 = invoice date + 90 days

Contracts or agreed payment terms may define dates differently. Use the terms you agreed with the customer.
