請英語好的朋友幫忙翻譯壹下，找對方采購幫忙催款，希望說的委婉客氣壹些。

Could you please do me a favor. We are just informed by our Financial Department that we still have not received the payment for Purchase Order 486, which was issued in 2011. Please

help check out if your company has already transfered.

Thanks and regards，

專業翻譯，望采納！謝謝
