Monthly billing allows you to bring all of a member's expenses together on a monthly invoice.
(not only activities, but also Bars consumptions, if this module is installed)
This setting is only accessible to the Klubs admin.

Procedure
At the start of a new month, each time the previous month (activities and Bars) can be billed together:
- monthly billing for the entire previous month (1st day to last day)
- all invoices or individually per member
Processing
Invoicing then goes through regular financial processing (Yuki or Treasurer) with an invoice line for each transaction.

This then also with care for correct processing, as in individual billing:
- VAT code
- General Ledger Account.
