Merchant Support

We understand that every business is different, with unique and individual challenges. We also understand that managing electronic payments is simply a function of your operations and not your core business. CMS is committed to providing personalized, industry leading training and support for our merchants to make the process of managing your payments as hassle-free as possible.


Our well-trained staff is dedicated to maintaining the highest levels of professional standards. Our support representative–to–customer ratio is among the best in the industry. Our pledge is to provide each customer with fast, friendly and reliable service.


Additionally, our online reporting tools allow you to easily navigate through your merchant activity, giving you access to every transaction, refund, retrieval, chargeback and deposit.
