ChatGPT for Consultants: Prompts That Make Client Work Faster

Consulting is selling thinking. The problem is that 60% of what gets billed is production work — writing the deck, drafting the email, formatting the deliverable. That's not where your value is, and it's where ChatGPT can absorb the most load.

I've worked on enough client engagements to know which parts kill time. Here are the prompts I reach for.

Deliverable Writing (First Draft in Minutes)

The blank page problem is real. A mediocre first draft that you can edit is worth ten times a perfect draft you haven't started.

Prompt 1:

"Write a consulting deliverable memo on [topic] for a [industry] client. The key finding is [your main point]. Include an executive summary, 3-4 supporting points with evidence bullets, and a recommendations section. Tone: direct, professional, no jargon."

You'll edit it — you always do — but now you're editing instead of staring.

Prompt 2:

"Here's the raw data/notes from a client meeting: [paste notes]. Turn this into a clean summary memo: situation, key decisions made, open items with owners, and next steps. Maximum one page."

This alone saves an hour per client meeting.

Slide Outline Drafting

Structuring a deck is often harder than filling it in. The skeleton matters more than the design.

Prompt 3:

"I'm building a 10-slide deck to present [recommendation/finding] to a [role: CFO/board/ops team]. The audience is skeptical and data-oriented. Outline the slides: title, one-sentence objective per slide, and what type of content goes on each (chart, table, bullets, etc.)."

Plug this into PowerPoint or Figma and you've cut scoping time in half.

Prompt 4:

"Review this slide outline and tell me: where will the client push back, what's the weakest logical link, and what slides could be cut without losing the core argument? [paste your outline]"

Use it as a pre-presentation stress test before the client sees it.

Stakeholder Email Drafting

Communicating with clients, partners, and internal teams is constant. The emails that matter most — escalations, status updates, sensitive asks — take the longest to write.

Prompt 5:

"Write an email to [stakeholder role] about [situation]. The goal of the email is [one clear objective]. Tone should be [direct/diplomatic/urgent]. Key facts: [3-4 bullets]. Keep it under 150 words."

Prompt 6:

"I need to send a difficult email: [describe the situation — missed deadline, scope change request, delivering bad news]. Help me write it in a way that's honest, doesn't over-apologize, and keeps the relationship intact."

The edit pass is fast when the tone is already calibrated.

Discovery Question Generation

Good discovery questions are the difference between surface-level work and a diagnosis that actually leads somewhere. Most consultants use the same 10 questions on every engagement.

Prompt 7:

"I'm starting a discovery process with a [industry] company facing [problem/situation]. Generate 15 diagnostic questions that would surface root causes, not just symptoms. Prioritize questions that would reveal whether [specific hypothesis] is true or false."

Prompt 8:

"I have 45 minutes with the [COO/VP of Sales/CFO] of a client. The engagement is focused on [topic]. Write 8 questions designed to: understand their biggest constraint, identify internal politics I should know about, and find quick wins I could point to in month one."

The Rule That Keeps This Useful

ChatGPT is fast and generic. Your judgment is what the client is paying for. Every output above needs your professional filter — checking it against what you actually know about this client, this industry, this situation.

The prompts accelerate production. They don't replace the analysis.
