"I have been working with Differenz Systems for 4+ years and I can not speak highly enough about what we have accomplished together. We took an idea from a concept to a fully-implemented mobile platform in months and have continued to enhance, refine and implement the software including numerous projects for the largest credit card reader company in the world. Without exception the team at Differenz has solved every challenge I have posed. Without exception the team at Differenz has responded to every question, every scope change almost immediately. They work fast. They communicate professionally. They provide updates daily when necessary and work independently when required. I feel Differenz Systems is an extension of my own team. They have earned my trust and even admiration with their quality work and have enabled me to grow my company with the confidence to know we can tackle any technical challenge, together."
