Customers today expect the businesses where they shop to accept a wide range of payment types. This includes not only cash and checks, but credit and debit cards as well. If your business does not allow customers to pay with plastic, you could be missing out on a tremendous volume of sales. This incorporates online sales, since credit and debit cards are two of the main ways shoppers pay for goods and services purchased online. The fact is, most businesses in the retail, mail and telephone order, and online industries have to accept credit and debit cards if they want to remain competitive.
