Giving incentives to sales force, why not to your customers.

I came across many b2b clients in my career, i observe common charaterstics that when we give best service to our client they will not hesitate to give you more business. But going one step forward if you provide some type of incentives to your client they definitely give good reference where you can easily close the deal or sometime client only convince them. But beware its not applicable for all type of client. Incentives may be monetary or some kind of gifts or excellent service(above expectation). So we need to judge client and it can be possible when you interact more and more, understanding their needs and want.
