Under the Invoicing section, it's possible to create or delete an invoicing link for the commercial event in the schedule.
Interval: Specify a precise date frame on which the invoicing operations will be performed.
Filter: Select the operation to be performed. To determine if events scheduled within the given time frame will be set as 'not invoiced' (i.e. the link between the invoice and the event in the schedule is deleted, allowing the invoicing process to be performed) or set as 'invoiced'.
Days: Indicate the day(s) of the week the selected operation will be performed.
Once all parameters have been compiled, press the Start button to proceed with the invoicing operation, you will be prompted to select the invoice to which the invoicing will be charged.
Note: Please note that in case the "prepaid" invoicing option is enabled in the "Orders" tab, the "Invoicing" tab won't be managed nor displayed.
