Payment Terms Formulas and their meanings

The setup of Payment Terms in NAV can be confusing.

 In NAV we have various terminology that equates to a time period. For example:

  • D = Day. A number before this will equal the number of days. 20D = 20 days. If the number appears after the D with no sign in front of it, this means the next occurrence of that particular date. See below for an example.
  • W = Week.
  • M = Month.
  • CM = Current Month.


Additional to this, mathematical signs can be used in the equation, for example CM+20D which is basically saying, end of the current month, + 20days. So on, or around the 20th of the next month.

Some possible entries for Payment Terms and their meaning are listed below.
