Brief History

Management Services Unlimited, Inc., started out as a spin off from its sister company in Chicagoland Illinois.  Its company management team have been executing its customer service operations since 2011 handling field service operations from a call center in Illinois.  Thus, Lab Express Corporation became the first client of our business. Having started several companies in Illinois, we were challenged with a lot of administrative tasks that needed to get done but had to be done exactly right. With us spread very thin on time and Chicago being as expensive as it is, we didn’t have the money or infrastructure to hire fulltime local employees, so we needed to be creative.  Benefitting from its partner Rex Argana’s over 20 year’s experience with outsourcing processes and training various customer service agents, there is no doubt our team are more than ready to handle our day to day tasks. The team are both trustworthy and capable of delivering on what was promised.  They are being very efficient when learning new tasks so we didn’t waste time, and the turnover needed to be very low because retraining staff was not an option for us.

At MSUI, we implement documented processes that adapts to customer needs, and have team managers receive training so they can act as a backup and retrain someone new, when the need arises.   After selecting multiple providers to test out their abilities, we ensure they all can comply with the process set forth, to implement customer requirement with guidance from a well-mannered management team, and their ability to restructure their operations based on customers’ requirements. From there we really focused on operational excellence of being able to deliver what we say we can do. We accomplished this by testing out a wide range of activities on ourselves and if those worked we would offer them to our clients. We take our work very seriously and have instilled in our culture to deliver our commitment. And that’s why we give the free trial so we can understand customers’ need and understand how to work together.  We trust in our ability to provide you the best BPO service you can find.  Some of our clients start on a month to month basis, and they eventually end up repurchasing our service each month. We look at this as a long-term integration with our clients and become the virtual extension of their company. Because they are trusting us and it does take a leap of faith to do that but we’re hopefully the right people for the job. And even if we’re not, we’re able to add some value even in the trail process.
