I need advise. We had a customer pay a deposit on a sales order then changed their mind. We issued a refund check but now the customer has flipped again and now wants go ahead with the project. We are stumped on how to best VOID the refund check so that it clears off of the sales order and returns the customer deposit to the same sales order. I'm told that we can't simply void the check and rely on it clearing up the funds to attach as the customer deposit. I'd appreciate any advice!
