For a merchant accepting PayPal is a no-brainer. These days all have have a paypal account in fact, paypal claims 254 million active customers accounts and 17 million traders. Setup or use is simple and you can get it for a very short time. Your customers do not even need a PayPal account. One of them is good because it is possible.
PayPal’s terms and conditions are fairly transparent, which does not lock you into a contract with a stop proof fee. The number of given combinations is unreal, so you can be sure that you have copied PayPal with purchase cart, accounting application or shipping software. PayPal papers offer a mPOS application here.
In my opinion until you change it to the big leagues, PayPal is fully equipped to grow your business from one day to another. Nearly a contract, monthly fees and a strong suit for merchants can not be denied at any time.
