Saw this thread got resurrected and thought I'd chime in...
So, at the time of my last post I was looking at Elavon through Costco, and tried it for less than a month. Horrible, horrible experience with them - and judging by the online feedback (which I should have looked into first) I am not alone. Terrible customer service, hidden fees, tried to make me pay for equipment rental, etc. even though I told them I wanted none of it. To make matters worse, even after I cancelled with them they kept deducting the monthly fee out of my account for 4 months after the fact, even though I called numerous times, even spoke to managers, etc. all promising they would rectify the problem. Finally, I called my bank and had them take care of it.... Please take my advise and steer clear of Elavon.
Anyway, Square is great, but typically you can save money if you're doing an average of $5k+ per month with other processors. I really had no problems to speak of and still have an account active just in case... However, I will share a story about a bad experience with square from a very close friend of mine who owns a printing business. About a year ago they were hit with a $3,000+ chargeback. It was all due to a direct mail piece that had nearly $2,000 in postage and the actual printing was only worth $1000. Halfway through the job his press broke down and he had to order a part which delayed all of the mailers from going out for almost week. The customer was informed of this and agreed to mail the 1/2 that was done, and then mail the rest when the press was fixed and they could finish printing. All of this is documented in emails. However, the following month the customer decides to do a chargeback because they apparently didn't get the response from the mailer they were expecting and blamed the fact that 1/2 the mailers were sent out a week late. (For arguments sake, none of this was time sensitive - basic advertising piece.) Anyway, the printer contacts Square and explains all of this, emails copies of the documentation etc to show they did nothing wrong, mailers were printed and mailed as agreed and the customer was aware of the week delay. About 3 weeks later Square informs the printer that they ruled with the customer and that is it. *Come to find out later from a person working in the credit card industry that Square can't risk pissing off any of the credit card companies and that they play ball with them first and the customer comes second. So, if you're ever in a pinch over a chargeback issue, be aware 99% of the time you are going to lose that battle if Square is representing you.
Sooo.. fast forward to today and I am doing business with a family friend through a local processing company for rates far better than square, no equipment rental or charges and I have no contract so I can leave whenever. I will admit this is a special arrangement for me and lots of fees and such were waived, but any of those could be argued about if the processor wants your business bad enough. So far, so good, no complaints. I have an actual CC terminal with receipt printer and monthly statements mailed to me, and my very own CSR who will go to bat for me in the event a chargeback ever happens.
