My employer has sold a fixed asset ( Dump Trailer) for $3,500 plus tax, an invoice was created and a payment was applied in the "Receive Payment" Module and then the payment was recorded in deposits module. 

Now I have to do the journal entry to remove the inventory, but can't db the bank as that's already been done, so I am missing an account to balance the transaction or should the payment not have been done that way?
