A landscaping company in Brookfield
10 computers, cloud-only Microsoft 365 · $1,250/month
The problem: No internal IT and an office manager with nobody to call. When a computer or printer stalled, crews sat in the office instead of getting out the door on schedule.
What we run: A fully managed plan: Microsoft 365 administration, email security, managed firewall, and on-site visits when hands-on help is needed. The same full security stack our larger clients get, sized for ten computers.
Support requests typically answered in 5 to 15 minutes
Same-day on-site for anything critical
One flat monthly invoice, no per-incident charges
“Working with Powerful IT Systems has really felt like having an internal IT person without having to add another person to my payroll!”
The problem: Patient and practice data on physical and virtual servers, staff access to sensitive medical records to control, and systems that cannot go down during patient hours.
What we run: Full-service managed IT: every server patched, monitored, and backed up with verification, managed firewall and wireless, role-appropriate access to medical data, and unlimited on-site and remote support.
Server alerts handled before the first appointment of the day
Streamlined, controlled staff access to sensitive data
Staff focus on patients while the technology that charts, bills, and schedules simply works
“The staff is friendly and responds quickly to any questions or problems and they have really helped us streamline our IT system. I would highly recommend them.”
The problem: Two offices, eight servers, and a business that lives on shared files, deadlines, and client communication. IT had outgrown tickets: someone needed to own the whole stack.
What we run: Full managed IT across both sites: Microsoft 365 and email security, backups and a maintained disaster recovery plan, firewall management at both locations, vendor coordination, and quarterly strategy meetings.
One team owns the environment end to end, including vendors
Disaster recovery plan maintained and reviewed, not just written once
Quarterly strategy sessions instead of break-fix surprises
“They offer full-service IT support and address technical issues quickly and professionally. Powerful IT Systems can save your company both money and time.”
