Recurring invoice frequency control
          You can control the frequency of recurring invoices with frequency options such as billing on an annual, quarterly, monthly, semi-monthly, or weekly basis.
         
         You can also define a non-standard cycle code for recurring invoices.
This table shows the parameters that you are required to define for each frequency option:
| Option | Field to be defined | 
|---|---|
| Bill by a non-standard frequency | A cycle code | 
| Bill on an annual basis | Bill month (1-12) and a bill day (1-31) | 
| Bill on a quarterly basis | Bill month (1-3) and a bill day (1-31) | 
| Bill on a monthly basis | Bill day (1-31) | 
| Bill on a semi-monthly basis | Bill day (1-15) | 
| Bill on a weekly basis | Bill day of the week | 
          Note: If you define the bill day frequency to be 31, then the customer is billed on the last day of each month.
         
         A cycle code is a non-standard frequency that you use to create and bill invoices. For example, you can define a cycle code to assign to recurring invoices. The cycle code is used to create the recurring invoices every three weeks, the second Tuesday of every other month, or another non-standard frequency that you use.
