Step 1: Invoice settings (group)

In the group module settings -> invoices tab you can set your invoice settings.

Automated invoicing:
Automated invoicing is not possible for the group module.

Zero charge invoices:
If this setting is enabled, invoices will be generated even if the total amount of the invoice is zero. If this setting is disabled, invoices will only be generated if there is at least one paid item.
Please note that this setting may differ from the participant invoices.

Primary invoice data:
Determine whether the address included in the invoice should be taken from the billing address (if there is one) or from the group data. If the billing address is the primary address, the invoice will be sent to this email address. The regular email address of the group will then be used as a CC email address instead.
If no email address is entered at the billing address, the invoice will be sent to the group's email address. 
Please note that this setting may differ from the participant invoices.

New invoice for same total amount:
Generate new credit notes and invoices for groups who changed their selected items, even when the total amount due is the same as their previous invoice.
Please note that this setting may differ from the participant invoices.

Separate invoice numbers
Group invoices and credit notes have their own unique numbering sequence, separate from the participant invoices and credit notes. You can only change this setting if no invoices have been created yet.

Invoice number prefix
The invoice numbers will be displayed as the entered text, followed by the generated invoice number.
Please note that this setting may differ from the participant invoices.

Invoice number length
The lenght of the invoice number, without the invoice prefix.
Please note that this setting may differ from the participant invoices.

Invoice number preview:

Payment reminders:
You can set the number of days after the last invoice/reminder for each new reminder. You can send max 3 reminders.
Please note that this setting may differ from the participant invoices.
