"Sekure Merchants is simply a phenomenal company to work with. My business partners and I have been with WF, BofA, and other "top tier" merchant services providers but Sekure was our solution. Excellent and proactive customer service from Marybeth, and phenomenal onboarding with Josh. Processing rates are excellent and hardware support has been fluid and turnkey."
