      HCLTech played a crucial role in supporting our transition to an independent entity, ensuring it was completed within the planned timelines and without any business disruptions. Their global capabilities, expertise in critical projects, and deep understanding of the automotive business value chain made them the ideal IT partner.

      Service guys and operators are kind and good at what they do. Since being taken over, the Acct Manager we deal with is rude, short and acts like everything is a problem unless she thinks she's going to get a sale. So kind and responsive at that point, the rest of the time, No.

      One of the largest and fastest growing IT services providers in the country. Knowing I can call the support desk 24/7 for solutions, when we deal with real deadlines with real consequences, makes a huge difference for me as well as our staff. And, for the most part, we don't have to call the support desk because everything works. The only times I have to reach out is when we hire a new person, or add a new service or license. They are very pro-active and results oriented.

      Sean Pratt's Review Sourced from Google

      The company we hired to handle the IT services for our small business sold out to these guys and the service we received plummeted. We were paying a ridiculous monthly fee for managed IT services yet the few times we'd actually need help we would end up on hold forever and not receive calls back when promised. It took them almost two weeks to get a computer connected to our network and over a week to connect a new check scanner. **Edit: They were helpful with the offboarding process to our new IT company. The owner of the old company we had originally contracted with did reach out, which was appreciated. I really still feel that the IT services we were receiving were sub-par.

      Used a fraudulent tracking number to "placeholder" a shipment, the tracking number was set to re-deliver to their address. The item they claimed to have shipped was the wrong weight (4lb) when the actual item in a box is exactly 6.1lbs. When asked about the questionable tracking, they opted to refund the order instead of fixing it. As a note, they were underselling MSI Direct on a motherboard by almost $150...

      Ordered a product from them off of Amazon. They were never clear on shipping and claimed they sent to UPS but UPS says they never received. This company just wants to hold your money and when you finally call them on it they fold but if not they will hold your money as long as they can with no explanation as to why. They never reached out to me once until I called them up after I was past delivery time with not a single word.

      My office network crashed on Friday. VQIS was there the same day to diagnose the problem. They got it up and running the same day, and recommended a couple upgrades to insure it would not continue happening. They were out the following Monday to repair/replace the equipment. A+ for these guys, all of them know what they are doing and they had me up and running within hours of the initial phone call. THANK YOU VQIS!

      Top notch all the way! Professional yet personable. Extremely good at what they do (Mac or PC) and they explain everything in a way I can understand. VQIS does remote monthly maintenance on my work laptop (windows), as well as takes care of my family’s non-work iMacs when we have issues. I trust them so much that I’m willing to drive an hour and a half to bring them my computers if they need to fix hardware issues. Fast turn around with status updates along the way. All with a friendly attitude and a great sense of humor, which is always a plus!
