Why not use customer express account

We have suffered "express cost to be paid" problem before with following customer

The price we quoted are factory price,both party could find it in talking history and email,however,the customer use FEDEX express policy and refused to pay the freight cost(they got goods already),when the fedex could not get the express cost then turn the gun to ask us for payment, and it is much more than it should be.For  example,the 500pcs bottle cooler shipping cost to Netherlands is about USD200-USD250,while they use the lawyer to ask us to pay USD900. We need to spend much time in honest business,rather than such bothersome issues.

Such small order could brought us about USD700 loss,if the order are big,the potential loss would be much more than this.

Plz understand we do not accept express company collect goods from our company under freight to be collected items,as many express company would still ask sender for freight cost if customer refused to pay it,the two solutions are as follws
1.we arrange the experss and charge express cost
2.If you have express agent in china,we could sent goods to your appointed place,freight to be paid(domestic express cost is no too much),then we complete our mission after your express agent receive the order,they would send the order to you by themself.
