About ProCFO

A new firm.
Four decades of expertise.

ProCFO Business and Tax Services was founded in 2024, built around the expertise Stephen Challinor has spent a career developing. Stephen founded his first Illinois CPA firm in the 1980s and has navigated every major shift in federal and state tax law since.

"Tax software is good at math. It doesn't know that you have a home office, that your car qualifies for a deduction, or that your side business changed your filing situation. A CPA does."Stephen Challinor, CPA · Founder

Why ProCFO
"Your accountant should be more than a return preparer."

Most small business owners only talk to their accountant once a year at tax time. ProCFO is built for year-round partnership: strategic advice, clean books, and proactive guidance that prevents problems before they start.

“

Stephen caught a deduction I had missed for three years running. In one consultation he found more than I expected to save in five. I will never file without a CPA again.

We switched to ProCFO after our previous accountant missed our quarterly filings. Stephen got us current, set up a clean payroll system, and has been our financial partner ever since.

As a nonprofit, we struggled for years to find a CPA who understood fund accounting. Stephen knows exactly what he's doing with Form 990, and our board finally feels confident in our financials.
