"Great company to work with. They have custom designed a software system for us at Gallagher Pools and Spas which has made all of our day to day tasks much more efficient. Have had other software programs in the past with very poor support and very limited to changes and updates to their systems. Not with Carroll Data Processing. Lisa and Michael are always available for any questions or changes and updates to our system. HIGHLY RECOMMEND them for all your computer/software needs!!!!"

"Mid-Atlantic Tech has been working with Carroll Data Processing for about 3 years. They are a pleasure to work with and we use them for all of our programming and custom software design needs. They have really helped our clients by modernizing in-house software solutions that were approaching end-of-life. We will continue to recommend Carroll Data Processing to our clients."
