As a merchant, you have a number of goals. Merchant solutions to common problems start first and foremost with the desire to continue existing as a merchant. This leads to a sub-goal of bringing in enough money so that you can pay your light bill and your staff and buy whatever you are providing to the customer.
What attracts people to your business? Is it the décor or the high quality of product? Is it the warranty and service? Is it the convenient location?
No matter where you are and what you sell, people need to have money to buy it. And the truth of the matter is, most of the people are shopping with credit and debit cards now, not cash or check. So, merchant solution number one is: accept plastic.
