5. Follow up and follow through. What really shows the customer your value is how you follow up after a sale or after you've promised them some information. Every time you follow up, make sure you have a new idea or new information to share so you're always looked upon as positive. Go back to every one of your customers and thank them for their business and ask if there is anything you're not doing that you could be doing to serve them better.
