Feedback:
In the greater Houston area Trudy King is the best rep one could ask for. Trudy and Mainstream are very attentive to clients needs. I highly recommend their services.
Feedback:
I would not recommend this company to anyone and further more the 1 guy on here that left good feedback for the company Darrell Gilliland is employed by the company which shouldn't be considered as feedback is concerned.
Feedback:
Fantastic, honest, company with great employees and competitive rates.
Feedback:
Mainstream merchant services is by far the most fair and ethical company in the merchant services industry. I have use their services for many years and they have never raised my rates or increased my fees. My sales rep Jeff Carrick was always prompt with his service and honest with my questions and concerns. If you are considering using Mainstream Merchant Services, I highly recommend them.
Feedback:
Great customer service! With great rates and local support! Worked with Albert Parrales here locally in Central Florida. He is fantastic.
Feedback:
As a small business owner, I've paid inflated rates for years form other processors. Since I've been with MainStream, I've saved considerably, and I have not noticed any hidden fees - fees that I used to have to pay with my other processor. What's worse, I didn't even know about those hidden fees until MONTHs after I had signed with them. I highly recommend MainStream because they do not use those business practices!
Feedback:
Absolutely the lowest processing rates I've ever paid! Thank You!
Feedback:
Mainstream has been fantastic! Consistent support and so easy to work with! Would highly recommend making the switch if you have the opportunity!
Feedback:
this company is good at merchant services and better than others out there in the industry
Feedback:
Good Service! Installation was easy and the sales rep followed through with everything promised.
