Client Testimonials

“When my restaurant profits started to decline due to the impact of COVID-19, I knew I had to find ways to mitigate my expenses. Merchants United was surprisingly able to reduce my credit card processing bill by 95%. Seriously, it really was a no-brainer to make the decision to switch.”

- Restaurant Owner

“As my business was fortunately growing during this pandemic, so was my credit card processing bill! I was referred to Merchants United from a friend of mine, who said they could reduce my bills by 90%. Long story short, I actually saved OVER 90%. I just wish I switched sooner.”
