Working in Illinois
What is actually different here.
Tax and entity context
Illinois applies a flat personal income tax rate, which makes owner distributions predictable to plan around.
Season and demand
Hard winters and hot, humid summers give HVAC two strong peaks. Deep winter freezes produce concentrated bursts of emergency plumbing work, often across a handful of days.
The market
The Chicago metro anchors a mature, competitive market with a large commercial and industrial base. Prevailing wage work is common on public projects, which puts more weight on payroll classification and record-keeping than in most states.
We work with contractors across Illinois, including Chicago, Aurora, Naperville, Rockford and Springfield. Everything runs remotely and through scheduled calls, so where you are in the state makes no difference to how quickly you get answers.

In their words
Contractors who handed the books over.
HVAC
I was doing books at the kitchen table at 11 at night after a full day of service calls. My wife finally told me it wasn't sustainable. First month ADB took over, they found $12,000 in expenses I'd never categorized right — parts, fuel, the works. I got my evenings back and I found out I'd been underpricing my maintenance agreements for two years.

HVAC
In summer we're drowning, in winter we're wondering where the money went. Nobody I'd worked with before understood that rhythm. These guys built the books so I can actually see what my slow months cost me, and now I plan for them instead of panicking in February.

Honestly I said yes because the first month was free and I figured I'd get what I paid for. Then I got the report back and it was cleaner than anything my last bookkeeper sent me in 5 years. I signed on the same week.
