Where It Helps

The work that piles up during busy season, organized by service line.

Tax, audit, advisory, bookkeeping, client relations — every output still goes through normal review before it reaches a client. This just changes how fast the first pass arrives.

TAX

Research & explanation letters

A faster starting point on research questions and positions, plus quick drafts of client explanation letters once a return is finalized.

AUDIT

Workpaper & findings support

Draft findings and management letters from completed workpapers, with the source data never leaving your engagement files.

ADVISORY

Forecasting & scenario modeling

Run cash flow or budget scenarios using a client's real numbers, kept entirely inside your own access point.

BOOKS

Statement summarization

Get a fast first read on a client's statements — trends, ratios, flags worth a closer look — without uploading the file outside the firm.

CLIENT

Letters & engagement summaries

Turn a finished analysis into a clear client letter or engagement summary, in the time it used to take to start one.

What Makes This Different

Speed is only worth it if the numbers stay yours. So they do.

A trial balance has to tie out to the dollar. The question of where client numbers actually go deserves the same precision — and most firms have never actually checked.

Owner compensation, pending acquisitions, payroll detail — line items like these carry weight precisely because they're not meant to circulate. Some consumer and lower-tier AI products are permitted to retain and learn from what's entered, with no concept of engagement confidentiality built in.

Illinois AI Services LLC gives your firm a private point of access to AI models — built so that client financials stay inside your firm, never used to train a public model.
