I had some concerns when PowerPay was absorbed by Evo, but there has not been any noticeable change in my service or rates. Frankly, convenience is much more important to me than rates, since bank fees are just a part of my overhead and fully deducted.
I was pleased to see an alternative processor, but after reviewing what I thought was a very cumbersome contract, followed the method of inertia and stayed put.
While they are not offering it to me since I am an "old" customer, they are offering a chip reader to new customers, which makes now an attractive time to switch.
I am an old cynic, and suspicious of anyone who wants a long-term contract in order to provide a basic service. When I signed up with them, those many years ago, it was a one page sign-up that was very straight-forward. I'll be interested in hearing if they are still offering a simple and understandable contract.
