Small Business IT Support in Chicago

No full-time IT? You don't need one. You need a senior engineer you can call when something breaks, who shows up, fixes it, and doesn't lock you into a contract. That's the whole business model here.

ITIL-certified Fully insured · COI on request Same-day response

The problems I get called for

Offices, shops, clinics, warehouses, branch sites — different businesses, same story: technology problems pile up until they cost real money.

Everything runs through one person

Usually the owner or office manager is the unofficial IT department. When the problem is beyond a reboot, work stops. I'm the number you call at that point.

MSP contracts don't fit

Managed-service contracts are built for bigger companies. If you need help a few times a month — or a few times a year — paying a monthly retainer makes no sense. I work on demand.

Problems keep coming back

A rotating cast of techs means nobody knows your setup, so the same issues resurface. One engineer who keeps your context fixes things so they stay fixed.

What I handle for small businesses

The everyday problems and the emergencies — handled clearly, quickly, and in person.

Work order — what I handle
  • Computer & laptop problems — slowness, crashes, upgrades, replacements
  • Office 365 & email — setup, migrations to the right plan, Outlook & Teams issues
  • Wi-Fi & network — dead spots, dropouts, and "the internet is down"
  • Printers & scanners that refuse to cooperate
  • New-hire setups — computer, email, and accounts ready on day one
  • Urgent outages — same-day, on-site response whenever the calendar allows
  • Office moves, expansions & honest advice on what to buy (and what not to)

One engineer. Same face every visit.

Dispatch networks and big MSPs put a coordination layer — and a margin — between you and whoever shows up. With IT-OnCall, you hire the engineer, not the markup.

I'm ITIL-certified with 15+ years in IT operations, from field engineering to running a multi-site service desk for 1,400+ users. Your business gets that experience directly: same face every visit, clear explanations in plain English, and no pressure toward contracts or bundles you don't need.

Need an IT guy you can actually call? Let's get it sorted.

Tell me your location, the problem, and when you need someone there. One fix, a project, or recurring visits — your call. Serving small businesses across Chicago, the suburbs, and greater Chicagoland.
