Please Help!

When making a stock purchase thru the MoneyPaper service,
the company requires that you send them a amount equal to
10% above the total actual cost of the stock plus fees. This
10% cushion will be returned to you if it is not needed to
cover any increase in the market cost of the stock.

My question is how do I reflect in Bivio these transactions?
If I reflect a purchase that cost in total $100.00, but I
sent them $110.00, when I receive the $10.00 back, how do I
reflect that in Bivio?
