Frequently asked questions
What is managed IT?
A flat-rate model where we proactively run your IT: monitoring, help desk, security, backups, and strategy, so you are not paying by the hour every time something breaks.
Do you replace our internal IT or support it?
Either. We can be your whole IT department or work alongside an internal person, taking the day-to-day load so they can focus on higher-value work.
How is pricing structured?
Flat, predictable per-user monthly pricing. See pricing or book a free consultation for a tailored quote.
Are you onsite or remote?
Remote-first. Most support and projects are delivered remotely, and our own team comes onsite as needed, billed per project.
