Dr. Wilson wrote an interesting article on how to shop for a merchant account. There are a few points he mentioned that I would like to discuss as some I do not agree with.  He does a good job with the definition clarifications.   I do not agree with his comment about a merchant may not be able to save money on Interchange plus pricing unless they have a lot of mid/nonqual.  You really can’t compare the two pricing models, but Interchange plus is always the way to go.  As he stated, it is more transparent and you know the exact profit you are dealing with.  Why would you go for the other when you have no idea if you are wasting your time on a possible few dollar savings?  I also disagree with his comment on the early termination fees.  I think it is critical to have some kind of agreement in place. credit card processing companies invest a lot of money, resources and time boarding a single merchant. To have them cancel in 3 months because their business didn’t pan out, is a solid way for them to lose a lot of money. He also recommends contacting your bank first, which I would not for various reasons. Many smaller banks simply outsource the service to companies such as ourselves. Second, I have found many banks, especially the bigger ones to take advantage of that relationship and not offer the most competitive pricing. Lastly, he does mention look online for complaints about the company, which is a great idea!
