Interest invoices can be created via Maintenance Routine in Sales ledger module. In Sales Ledger module go to Routines, choose Maintenance - Create Interest Invoices.
It's suggested to run Interest invoicing report first, for particular period to see which invoices should be created. Then run maintenance.
When invoices are created, it will appear on Invoices list. It's suggested to check if all are looks correct and then tick OK and save. Print them as usual.
TIP: If you want to keep Interest Invoices separate from Sales Invoices, there is a setting in Sales ledger module. Sales ledger>>Settings>> Interest invoices- number series. It allows to set up separate number series for Interest invoice.
