The engagement cycle, reframed
In most firms, the AI assistant is introduced “to help internally.” It’s used for doctrine, for technical answers. Fine.
But the strongest commercial potential is to use it as a continuity thread with the client across the five stages of the engagement cycle.
Step 1 — The quote: out of the boilerplate
The firm assistant, fed with your last 200 quotes, proposes a precise draft the moment you describe the client context in two sentences: size, sector, expected scope.
Gain: 15 to 30 minutes per quote, and pricing consistency across staff — which tends to drift in distributed firms.
Step 2 — Scoping: stop forgetting things
Once the engagement is won, initial scoping is the moment when most things get missed. List of documents to request, calendars, sector-specific watch points — it’s noted somewhere, but you don’t think to look.
The firm assistant, queried with “25-person client in construction, full engagement, first fiscal year”, returns in fifteen seconds the exact list of points to cover, based on equivalent engagements from the last three years.
Step 3 — During the engagement: the client becomes autonomous
Here is where perceived value jumps. The client gets access to an assistant that knows only their file, watertight against the firm’s other clients. They can query it 24/7:
- “Did you say I could expense this as a business cost?"
- "What VAT rate was applied to the Petit quote?"
- "How much does a deductible training day cost me this year?”
The assistant answers with source citations. The client is reassured, and the firm sees 30 to 60% fewer inbound documentation requests.
Step 4 — Reporting: from slide deck to dialogue
The annual review is no longer a slide of numbers. It’s a dialogue where the client can, during and after the meeting, query the assistant to dig into a specific point.
Observed effect: the review runs 30 minutes instead of 90, because detailed questions are asked after the meeting, to the assistant, instead of during.
Step 5 — The debrief: what to work on next year
On request, the assistant analyzes notable variances, recurring issues, and watch points raised during the engagement. The firm produces a work plan for the next fiscal year, already discussed with the client.
Results, after six months of use
These figures are medians across three pilot firms (10, 14, and 22 staff). The main lever isn’t cost reduction: it’s the shift of firm value toward advisory.
