英语翻译你为什么不在我们签订合同前告诉我你想要佣金呢,这样我就会把付你的佣金算入我们的成本.在交易之后,我会如数退给你.

If you would have told us that you want us to pay the commission before we sign the contract,I could calculate the amount of commission into our cost and pay it to you after the deal。But now for this order,I am really sorry that I don't have any room to pay the commission to you,because we have very little profit。We will surely consider the commission in our next deal。Thank you for your understanding!
