请各位外贸高手帮忙，关于翻单的事，请问下面的几个问客户的问题怎么用英语表达出来？

1 你们的库存怎么样了，还有多少库存？
What is the situation of your stockpiles? How much stock you still have?
2 我们的产品质量怎么样？客户有什么反馈？
What are our product qualities like? What kind of feedbacks do we get from our customers?
3 你们的销售情况怎么样？卖得还好吧。
What are your sales situation? Do you sell well?
4 我们的产品还有哪些需要改善的地方？
Is there any improvement we need for any of our products?
5 你们是否有翻单的计划呢？
Have you any plan to repeat your orders?

以上翻译应该很地道，若有不明可以追问。

1. How many stock do you have left?
2. How is the quality of our product? Any feedback from the customer?
3. How is your business? Selling good?
4. Any place need to be improved for our produdct?
5. When are you planing to place the next order to us? 你们计划什么时候再下单给我们。（这句这样问显得我们比较有信心。）

How about your inventory, how many stock there?
