Our business offers a rare proposition: tangible results and value-realized commercial arrangements. This means that we can accurately measure, to the cent, the benefit we deliver for our clients. We are paid by sharing the cost-savings we deliver: there are no up-front fees and no catches.

I founded CMSPI in 1991 after it became clear to me there was a gap in the market for a merchant champion. Over 27 years' later and I'm proud that CMSPI is an organization that works for merchants and helps them optimize their payment arrangements... all while also fighting against unfair competition and regulation on their behalf.
