Applying a Prepayment

[MJSteklac]

My organization host two conferences each year. For each conference registrants can choose from 10 options (e.g. Full Conference, Saturday Only, No Meals, etc.). I have setup each of the options as a non-stock item in inventory.

Persons are encouraged to pre-register and pay $20 in cash or check towards their registrations. This happens up to 6 months prior to the conference. The persons who preregistered do not have to choose their conference option(s) and pay the balance until approximately 3 weeks prior to the conference date.

I have set up a $20 registration prepayment as a nonstock item in inventory. When the person chooses their registration options I set up an option in inventory where the price is set at $20 less. For example, if the full conference fee is $100, then I set up an item that is valued at $80.

There has to be a better and less convoluted way to handle this. Any suggestions?

I just use the "prepayment" option under the "Receive Money from Customer" for that particular customer.
