    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.

    The team at Differenz are hard-working, dedicated, and professional. We began working with them to develop 3 mobile apps for our company, and the results are exactly what we expected. Even as our needs and designs changed, the team accommodated every request, and was able to help fill in the gaps with their own expertise and creativity. We continued working with Differenz for our HTML5 needs as well, and are very pleased with the outcomes. Communication with their team is always prompt, professional, and thorough, even working late into the night. We highly recommend their services.

    Solutions Implementation Manager, G4S Australia

    G4S Australia has had a business relationship with Differenz Systems for more than three years. During that time Differenz have developed and supported significant components of a critical and complex system utilised by our organisation on behalf of a State Government Department. These components that included a mobile hand-held device all had critical availability and performance objectives had very specific interfacing requirements that had to be met for the system to operate as expected. The system was implemented on time and has been operating for a number of years without any significant issues. We have found Differenz to be professional, reliable, and easy to deal with; importantly they have skills to deliver what we needed when we needed it.
