Quick IT Tips
Practical advice for Greenfield businesses — whether you work with us or not.
- •If your Greenfield business is paying hourly for IT support, add up what you spent last year including emergency calls. Most businesses find that flat-rate managed IT costs the same or less — and you get proactive monitoring that prevents the emergencies in the first place.
- •Ask your current IT provider how they monitor your systems. If the answer is 'we check things when you call us,' you do not have managed IT — you have break-fix support with a monthly label on it.
- •Before signing with any managed IT provider, ask what happens when you want to leave. If the answer involves termination fees, data hostage scenarios, or long notice periods, that tells you everything about how they keep clients.
- •Greenfield businesses adding employees should budget IT setup time into their onboarding process. A properly provisioned workstation with security policies, email, and application access takes planning — not a frantic setup the morning someone starts.
- •Review your IT spending across all vendors — internet, phone, software licenses, support, hardware. Most Greenfield businesses are surprised to find they are paying three or four separate providers for things that should be coordinated under one managed IT plan.
What Our Clients Say
“Powerful IT Systems handles all our IT and are great to work with. Anything we need, they help out with pretty much immediately or same day if it can be handled remotely. They are also available for us at odd hours like when we have questions on weekends. Working with Powerful IT Systems has really felt like having an internal IT person without having to add another person to my payroll! Couldn’t recommend more.”
“Regularly checks in. Responds quickly.”
“Went BEYOND my expectations!!!! I called Powerful IT to see if my PC could be tuned up. It was older and running very slowly. Powerful IT Systems remoted into my system and looked every thing over. He then explained to me why my PC hardware was just not able to keep up anymore. More importantly, the prospect of trying to figure out what to replace it with was not something I looked forward to. Powerful IT Systems and I hopped on a major retailer website and he patiently walked me through several options until we settled on one that would work well for me and at a price-point I could afford. I was so relieved! I tried to pay Powerful IT Systems for his assistance but he refused saying he didn’t fix anything. I am extremely grateful for his time, expertise and guidance. I will definitely contact Powerful IT the next time I have an issue and highly recommend Powerful IT Systems to all my friends!”
