Square
Square is a giant in the merchant services provider industry. Founded in California in 2009, Square disrupted traditional credit card processing by removing the complexities and obstacles which many businesses face. Merchants need only get online and register and will quickly be able to accept credit cards for a transparent and flat fee. There are no contracts, monthly fees, software fees, chargeback fees and many of the pitfalls which are standard with many credit card processing providers. The model seems to be a success as the company has expanded its operations to several countries overseas and reportedly has over two million clients.
