We are looking to collect a partial payment thru our form.

The amount per product in our form is of $1995.00 but we only required a $500.00 Deposit, How can I accomplish that thru the system.

Let users know in your product label that the full price of the item is $1995.00 but that the payment they will be making is $500.00 for a deposit on the full amount.  Change your product cost to $500.00 and you're all set.
