The Fourteen-Cent Answer
Trusted AI for Accounting & Tax Firms — an Enterprise RAG Story
A fourteen-cent reconciliation difference that everyone wanted to write off turns out to be the shadow of $58,400 in unreported 1099-K income — and the CP2000 notice arrives at the worst possible hour of tax season. Book Fourteen of The Grounded Answers follows Hartley & Voss, a two-partner CPA firm in Cleveland, through the season it stopped running the practice on memory and hallway folklore: every client sealed in a knowledge namespace of their own, documents that verify themselves on arrival, a draft return computed from real IRS tables with the workpapers attached, an examiner-grade audit of the return BEFORE the IRS reads it, and Baxter — the AI staff accountant that answers from one client's file only, cites every number, and never once signs a return. For firm partners, EAs, CPAs and the staff who carry busy season: trusted AI on the firm's own documents, where the last signature stays human.
