Thank you. (補充早前寫漏了的禮貌)

Please notify xx(whoever needs to be notified) when supplies are running low.

Running low on office supplies? Report them to John Doe (x1234). The typical lead time is 1 week.

我是希望比較和善的態度，因為我不是主管。

謝謝。

When you are running out of office supplies(tapes, A4 paper...), please notify me and then I can call the suppliers to get them ready.
