How to bill Different Services of the same customer which start at different times?

I have a customer who has subscribed for 4 services. The first two services was provisioned on the 26th September and the last two was provisioned on the 9th of October.

The customer has been provisioned as “Recurring payments” for type of billing and the “billing day” currently set to 9.

I want to charge and track the customers services differently. How do I achieve that? For now once I click “to charge” it charges all services by applying prorated calculation.

We really need this,

i have customers who pay on the 15th
some 25th
some 5th

their disconnection must be 10 days from due date, we cant work with one billing period really guys

Solutions is bill all services in one day (per customer)

I’m don’t see any problem here
