Hi Abhilash,
If the end date is 10/03/2014, and the 'Final Invoicing''s date is 05/03/2014, then the amount of "Deposit 20%" which is $1000 will be in 'Invoice Amount with Final Payment'".
If the end date is 03/03/2014, then the amount of "Deposit 20%" which is $1000 will be in 'Invoice Amount without Final Payment'" according to the 'Final Invoicing''s date is 05/03/2014.
With the same Plan ID.
Like for example, if the Plan ID does not have any 'Final Invoicing'', then the amount of "Deposit 20%" which is $1000 will be in 'Invoice Amount without Final Payment'".
