Their Bill of Materials (BOM) software is incredibly precise. We’ve seen a 40% reduction in inventory costs because we’re no longer over-ordering parts 'just in case.' The AI-powered demand forecasting accurately predicts our seasonal spikes, keeping us lean and efficient.

I had the pleasure of working with Brandon Holland during a recent project where Wire Works Pro was hired to install networking equipment at one of their managed sites. Brandon was incredibly knowledgeable when it came to network configurations and troubleshooting, which made my job as an onsite contractor smooth and efficient. His clear communication and technical expertise ensured everything went according to plan. Looking forward to working with him and the Xobee team again in the future!

When technology throws a wrench into your day, you hope someone like Maribel shows up.We had a few challenges with our office server and without even needing to know the ins and outs of our industry, Maribel from Empowered IT Solutions jumped right in and worked her magic. She was methodical, sharp, and incredibly easy to work with. Within a short time, what felt like a major disruption became a resolved issue, thanks to her calm confidence and technical skill.Highly recommended!!

Fred Farmer's Review Sourced from Google
I recently had the pleasure of working with Empowered IT Solutions to set up a new computer, and the experience was absolutely top-notch from start to finish. I want to especially recognize Aaron Hernandez, who assisted me throughout the process. Their knowledge, professionalism, and patience made all the difference.Setting up new technology can sometimes feel overwhelming, but Aaron walked me through every step with clear explanations and a calm, friendly demeanor. They took the time to understand my specific needs, answered all my questions thoroughly, and made sure everything was working perfectly before wrapping up.It’s rare to find someone so technically skilled who also genuinely cares about customer satisfaction. Empowered IT Solutions is lucky to have such a dedicated and capable team member. I’ll definitely be turning to them for future tech support and would recommend them without hesitation to anyone needing reliable, expert IT service.

I am so thankful to have the Empowered IT team on my team! I've had some silly mishaps and they've been available to hold my hand and help me through it. In one case they hoped on a team meeting with me and helped me explain the tech we're using and how we keep our files secure. I can't say enough good things!!
