What clients and partners say about CMSPI

Marks and Spencer

"CMSPI was an invaluable partner for us in ensuring that we were not only prepared but also optimized for SCA implementation. CMSPI’s analysis, benchmarking and independent advice allowed us to identify areas of opportunity and develop a market-leading strategy to optimize the customer experience. Their guidance in interpreting the regulatory changes and mapping out the impact on M&S provided insight into sales potentially at risk for abandonment and failure. In addition, CMSPI worked directly with our providers to ensure alignment across the supply-chain. By working with CMSPI, we were able to implement a strategy to significantly reduce potential sales losses. I would recommend them to any business looking to optimize its digital payments processes."

"CMSPI’s input has been invaluable – we had highly competitive rates, but, they enabled us to drive cost savings we simply couldn’t access ourselves due to market visibility and their data capabilities. Any merchant looking to optimize their payments costs should work with CMSPI – they’re truly the payments experts."

CMSPI continues to be our go-to partner for anything payments related, and I would highly recommend them to any payment teams looking to use data insights to enhance their results.”

“As a rapidly growing, international company, we have complex payment requirements. CMSPI recognized these requirements and, despite our multi-layered contractual landscape, created transparency for us and worked out clear plans to optimize our payments acceptance. CMSPI's team was very detail-oriented, reliable and able to deliver impressive results in a short period of time. We would recommend CMSPI to any multinational merchant looking to increase transparency and to drive down the cost of payments acceptance.”

"CMSPI’s deep payments knowledge was invaluable in building our payments strategy across Europe. With their data and insights, we were equipped with all the tools we needed to make the right decisions. We benefitted from significant savings in the short-term, while building the right foundation for a long-term strategy towards an integrated omnichannel payments supply chain."

"CMSPI fully managed and resourced a full RFP process for both our gateway and card acquiring providers, as well as providing insight and supporting direct negotiations with other third-party suppliers on our behalf. These projects both resulted in Ocado benefiting from a large six-figure savings amount annually. Our operations are complex as we work internationally and are expanding rapidly – CMSPI was able to understand these complexities and help identify best fit partners capable of implementing a solution that not only works for us now, but will continue to fit our arrangements as we grow. The ongoing support from the CMSPI team has been great, and they have helped identify charging errors and misapplied pass through costs in our old and new contracts which we continue to negotiate and optimise. We are thrilled with the cost reductions we have achieved, as well as the improved payments solutions and enhanced terms from our suppliers and wouldn’t hesitate to recommend CMSPI to other retailers."
