Hello there!!!

I am kind of new using QB, i am having problems dealing with an escrow account and also creating invoices. The part about the escrow account is getting reports by clients, where it will show me the history and balances per client. Regarding the invoices, I need to set up invoices for prepaid costs. The problem is that most of the times, the client don't pay the total of the invoices but an advance, and when I create the invoice i hit the prepaid cost account (liability) but its counting the total and not the amount paid!!! Can anybody help me with this??
