FSCS is led by Steve Semenko and built on more than 25 years of practical IT experience. You get a clear explanation of the issue, the options and the work being proposed.
One person stays with the technical problem instead of handing you a list of vendors to call.
The issue, the options and the work being proposed, in language you can use to decide.
Accounts, networks and backups are treated as one environment, not three separate tickets.
A record of the setup so the next change does not start from a blank page.
The first call is about what is getting in the way. The work starts after the scope, timing and cost are agreed.
What stopped, what is changing, and how many people are affected.
Accounts, computers, the network and whoever looks after them now.
A specific fix, a project, or ongoing support. Price and timing before the work.
Then document it, so the next change does not start from scratch.
Technology priorities look different in a clinic, a professional office and a warehouse. Start with the operation, then fit the technology to it.

Secure, reliable technology for busy clinical environments.

Email, documents, remote work, identity and support.

Networks, Wi-Fi, security and resilient connectivity.

Day-to-day support for offices that are growing and do not have internal IT.
