No matter what industry you are in your customers want to be appreciated. The other day I was talking with a man who told me about a tool he purchased. A couple of days after he got the tool, the sales rep from the store called him to find out how it was working for him. Not something you'd expect from a tool retailer.
However, they understand the value of follow up and caring. It didn't cost the sales rep anything except 10 minutes of his time. The payback is priceless. What can you do to show your clients that you care about their experience? How can you ensure that they are happy with your product or service? How certain are you that they will be returning?
Take some time to follow up. Make it a standard practice and you will quickly see the rewards.
