Frequently Asked Questions
How fast can I expect issues to be resolved with your IT support?
Speed matters in tech support. That’s why we resolve most IT issues in under 20 minutes, and 75% of all tickets are handled on the first touch. Unlike other IT support services that close tickets before the job is done, we see things through.
With our ongoing live support, your team gets real help when it matters most. No hold music, no delays; just direct access to our team of experts.
What makes your managed IT support services different from other providers?
Most MSPs assign a single technician. We assign a Strategic Advisory Team of professionals who manage your roadmap, compliance, budgeting, and service. We provide end-to-end managed IT support services, handling everything from onboarding to lifecycle planning.
With over 15 years of experience and a 95% satisfaction rate, we don’t just fix problems; we help prevent them.
What types of businesses benefit most from your IT support services?
We specialize in IT support for small to medium-sized businesses (SMBs), nonprofits, and schools —organizations that require responsive service without excessive hand-holding. Our managed IT support services are ideal for operations leaders who want fewer disruptions and more precise planning.
With structured onboarding, fast response times, and expert guidance, we help teams stay productive, reduce recurring issues, and avoid the chaos that comes with inconsistent IT computer support.
Do you offer on-site computer support, or is everything handled remotely?
We offer both. Our technicians are ready to provide fast, on-site computer support for issues such as network installations, cabling, or hardware repairs. Whether it’s remote troubleshooting or in-person fixes, our approach stays consistent: solve the problem entirely and quickly.
With over 6,000 end users supported across varied environments, our IT support specialists adapt to your setup without disrupting your operations.
Is your tech support available after hours or on weekends?
Absolutely. We offer continuous live tech support from U.S.-based technicians, with no outsourcing or chatbots. When something breaks outside of business hours, you shouldn’t have to wait until morning.
Our managed IT support services ensure your staff can get back to work fast, no matter the hour. We’re built for reliability, and it shows in our same-day resolution rate and long client tenure.
