Many a business has been lost by letting a trusted employee or partner gain the trust of customers by having sole access to them. If you hire or take on a sales or customer person, make sure you periodically show those customers that you are still strongly and intimately involved with the business. Use questionnaires, customer service representatives, and your own periodic personal calls and visits, to gauge how well your business and your employees are satisfying the needs of your customers. See if there are any new services, customer plans or products which might save you money or better fit your needs. Shop around and be sure you are getting the best price and quality.
Nothing gives the impression of a business in trouble as fast as a poorly maintained shop.
Get rid of the clutter. Get organized and show the customers and suppliers a streamlined first impression.
