Client Testimonials

“When I started the process of opening my restaurant I contacted Merchants United based on a recommendation from a fellow restaurant owner. Merchants United not only saved me time in researching vendors for my business, but they also found vendors for far less money than what I could find.”

- Restaurant Owner

“We have been using Merchants United for a few years now. They helped us pick out a new POS system and put into place a new payment processing service. That alone has actually saved us a significant amount of money from what we were paying. I just wish we found them sooner. They also helped us design, order and put into place our gift cards. We are very pleased with their attention to detail and I would trust them with any facet of my business; very knowledgeable and hands on.”
