CustomerBill resource has below two attributes to represent money.

• amountDue
• RemaningAmount 

We have a requirement to present the new charge amount , balance carried forward amount , total invoice amount and the outstanding balance.

Do we support the "new charge amount" , "balance carried forward amount" in the customerBill resource. If yes, which attributes represent them ?

Example: 

First Invoice:

• Previous Invoice new charge Amount : 0
• Payments: 0
• Balance Carry forward Amount :  0 (Previous Invoice new charge Amount +Payments)
• Invoice new charge Amount: 100
• Total Invoice Amount : 100 ( Balance Carry forward Amount + Invoice new charge Amount)

Lets say we have received a payment amount:  10

Second Invoice:

• Previous Invoice new charge Amount : 100
• Payments:  10
• Balance Carry forward Amount :  90  (Previous Invoice new charge Amount +Payments)
• Invoice new charge Amount: 100
• Total Invoice Amount : 190 ( Balance Carry forward Amount + Invoice new charge Amount)
