User wants to create a single late fee invoice for all previous unpaid invoices of the client.
Though there is no direct way to do this, it can be done in two steps.
- Create a standard late fee invoices for the client and total the amounts for each invoice to determine the total amount of late fees. Delete these invoices after determining this total.
- Create a manual invoice for that total late fee amount and include the appropriate line items (each late fee charge amount).
