About us

CMSPI is a team of expert analysts and consultants who advise merchants on how to optimise and reduce their payments arrangements.

The payment industry continues to experience significant change as payment methods become ever more innovative. With our 25+ years’ of experience of working with merchant payments we can help you navigate these changes in complex international markets. We optimise the cost of accepting payment from customers for goods and services, including transactions on cards, in cash, by cheque, by phone and online.

As the needs of the merchant community change in response to the rapidly evolving payments landscape, CMSPI is right there to meet those needs. As well as our core services, we also offer bespoke projects to suit your unique business requirements.

Don't take our word for it, here's what our clients have to say...

Our business offers a rare proposition: tangible results and value-realised commercial arrangements. This means that we can accurately measure the benefit we deliver for our clients.

I founded CMSPI in 1991. It was clear to me there was a gap in the market for a merchant champion, an organisation that would work for merchants and help them optimise their payment arrangements while also fighting against unfair competition and regulation on their behalf.
