You cannot "sell" ducks and apply that as payment for specific Members; there are regulations for not permitting one person specifically to benefit from your charitable purpose fundraiser for purposes of the Club.

You would separate your activities. The Selling of the ducks is its own activity, such as Sales Receipt.

If you then offer a scholarship discount for members' dues or "spirit packs" that has nothing to do with the fundraiser. It has to do with Discount or Write Off of the amounts no longer expected to be collected from that customer name. That is the credit memo, applied to their invoice for Spirit Pack. The credit memo is using an other charge item linked to an income account for "Sponsorship/Write off."

Never take public support funds and apply them as to benefit individual team members. That is a violation of fundraiser rules.
