Pro rata calculation:
The pro rata is calculated on the recurring products such as bandwidth.
Days left = Days of the month – Date of the scheduled installation on the job card. (Calendar event.)

Pro rata = Monthly amount – Discount amount.
This pro rata calculation is only on invoices generated out of lead to receipt where an invoice was generated from a job card. It will not be calculated on normal recurring billing and on manual invoices.
We are busy improving this feature by making it possible to select which recurring products should get affected.
