Choosing a merchant processor for your business isn't easy. There are so many providers out there that it’s sometimes hard to know exactly where to start. Many businesses focus on fees, which makes sense. Since each transaction costs money, it's only natural that you’d try to reduce processing fees as much as possible. However, merchant fees don't simply vary across providers. They also change depending on the size and nature of your business. For example, larger companies often qualify for lower fees than do smaller ones.
