IT Support for Accounting Firms in Chicago

Accounting runs on deadlines, and technology failures don't check the calendar. I'm a senior, ITIL-certified engineer who keeps your workstations, network, and email working — with same-day, on-site response when something breaks during crunch.

The problems I get called for

For most small and mid-size firms, there's no IT department — just a partner or office manager holding it together. That's exactly the gap I fill.

Deadline-season failures

A workstation dies or email goes down in the weeks before a filing deadline. You need it fixed today — and after-hours or weekend work is on the table when the office can't stop.

Seasonal staff churn

Busy season means temporary staff who need computers, logins, and email on day one — then clean offboarding when the season ends. I make both routine.

Heavy files, heavy printing

Client documents, scans, and large files move through your office constantly. When the network, the scanner, or shared storage slows down, so does everyone.

What I handle for accounting firms

Reliable, on-site support for the technology behind your practice — and the on-site hands for whatever your tax and accounting software vendors need done locally.

Work order — what I handle
  • Staff workstations & laptops — repairs, upgrades, replacements, clean setups
  • Seasonal onboarding & offboarding — accounts, email, and devices ready on day one
  • Office 365 & email — Outlook, Teams, OneDrive & SharePoint basics
  • Office network & Wi-Fi — reliability when everyone's working at once
  • Printers, scanners & document workflows
  • On-site coordination with your tax & accounting software vendors
  • Urgent same-day response — with after-hours options during deadline season

One engineer. Same face every visit.

You wouldn't hand a client's books to a different accountant every month. Your IT shouldn't work that way either. With IT-OnCall, the engineer who shows up is me — every visit, every season.

I learn your firm's setup, your software vendors, and your calendar, so busy season is planned for instead of survived. On one large, time-sensitive project, that meant nights and weekends until it shipped — that's the standard your deadlines get. Fully insured, COI on request.

“On a large, time-sensitive merger project, without his 200% input and overtime work — including weekends — the project would not have been successful.”

Need a tech before the deadline? Let's get it sorted.

Tell me your location, the problem, and when you need someone there. I'll confirm availability and scope fast — usually the same day. Serving accounting and CPA firms across Chicago and greater Chicagoland.
