wiley旗下的一个期刊，我交完版面费以后没有给我发票。我问他们要发票后他们给我回复了以下内容:
Kindly be informed that an invoice will only be issued upon the placement of an open access order. Following the completion of payment for your order, our system will generate a receipt to serve as confirmation of your transaction.
这意思是我想要获取发票的话需要进行什么操作吗？
