If you were to sell your business, what would be your greatest asset? Your location? Your equipment? No. A buyer wants to know who your customers are.
Do you even know who your customers are? In a newsletter article by Aurelia Weems, CPA and tax preparer extraordinaire, http://woodlands-cpa.com/, Aurelia points out that buyers are looking to connect with your customers. How can they do that if you haven't taken the time to develop an email list of your customers?
Selling or not, an email list of your customers is a gold mine. If they've bought from you once, they're much more likely to buy from you again. Give them helpful information and they will forward your email to other business owners helping you broaden your audience and potential customer base. Take a moment, gather their name and email address and build your greatest asset.
