Questions about Billing Accounts and new FinAccount code

[Jacopo Cappellato]

David, Andy, all,

I'm really interested to the new code about FinAccounts; I don't know 
much about them but I'd like to figure out if in some way that can be 
used in place of billing accounts.

I'm asking this because in my opinion there are some issues in the way 
billing accounts currently handle invoices/payments, for example:
if you create a billing account with the amount field set to, let's say, 
$1000, and then you take an order for $500 and associate it to the 
billing account, when the invoice is created for it, it is automatically 
marked as PAID (by the billing account amount). And this is not what I 
need for it (I would like to use the billing account to keep track of 
existing invoices and real payments, but only real payments should be 
applied to invoices).
