Your Merchant ID number (also known as a MID) is extremely important. It’s another number that you have to keep track of as if you didn’t already have 50 other things on your mind at all times. Wasn’t running a business supposed to be a dream come true? Elon Musk, now the richest man in the world (take that Jeff Besoz) once said: “Creating a company is a very difficult thing.
