Buy an accounting-firms library built around shared standards, audit, tax, and disclosure context before adding private client work.
Three arms, same model (gpt-4.1-mini), same question set — no context, raw-accumulating, hosted crystal. At turn 12 the crystal sent 3,444 tokens; the raw arm sent 51,313 — 15× more, compounding every call.

A formatting rule planted at turn 1 was checked deterministically every subsequent turn. No-context broke it 1 time (9 / 10 held). Crystal: 8 / 8 checkable turns held.
All three arms produced substantive answers through turn 12 with no meaningful quality decline. The separating factors are prompt size and instruction retention, not raw answer quality.
How this was run. 12 turns, Accounting Firms vertical, gpt-4.1-mini held constant across all three arms. Raw-accumulating arm: source corpus injected at turn 1, then full conversation history re-sent on every subsequent turn — the window grows every call.
Workspace subscription for firms that need shared standards and advisory context before private client work is connected.

Up to 16M raw-token-equivalent shared accounting reference coverage.
Raw RAG can inflate every prompt with retrieved text. The crystal keeps shared operating judgment compact and reusable, so teams buy a monthly memory layer instead of repeatedly paying for larger, noisier context windows.
Each plan includes protected access to prepared industry memory across the recurring work areas below. Your team sees the benefit in chat while the library's source construction remains private.
A standards-reference layer for classifying topics, terminology, and recurring interpretation questions.
A practice-support layer for common audit concepts, evidence expectations, and workpaper language.
A public tax and filing reference layer for common authority concepts, reporting language, and advisory preparation.
