Hello @maxcharron ,
Please see an older post here in which I describe in detail the correct way to handle a customer deposit. There are other things that I pointed out that were a response to the OP in that thread and which may not apply directly to you, but the basic principles of the deposit and how to record it are the same.

Good luck!
