For Event Planners ·
What you'll accomplish
By the end of this guide, you'll have a repeatable system for writing polished, client-specific event proposals in 15–20 minutes instead of 1–2 hours. You'll use ChatGPT's Projects feature to store each client's context — past events, preferences, brand tone — so every proposal feels deeply personalized without the manual research burden.
What you'll need
What you should see: A new project workspace with a instructions panel on the left. Troubleshooting: If you don't see Projects, make sure you're on the {{tool:ChatGPT.plan}} plan or higher — this feature isn't available on the free tier.
In the project instructions panel, paste a structured summary of your client:
CLIENT: [Company Name]
Industry: [industry]
Primary contact: [name, title]
Event history: [brief list of past events you've done for them]
Brand tone: [formal/casual/innovative/traditional]
Must-haves: [any non-negotiables — always need AV, always hotel venue, vegetarian options required, etc.]
Avoid: [any known preferences to avoid]
Budget range: [typical budget range]
Preferred vendors: [any vendors they've worked with and liked]
Click Save instructions.
What you should see: Your client context is now saved — every conversation within this project will know this background automatically.
If you have previous proposals, event recaps, or the client's brand guidelines, drag them into the project's Files section. ChatGPT will reference these documents when generating future proposals.
Inside the project, start a new chat. Begin with the event brief:
I need to write a proposal for [Client Company]'s upcoming [event type]. Here are the details:
- Date: [date]
- Expected headcount: [number]
- Venue type: [hotel ballroom / outdoor / corporate office / TBD]
- Budget: [amount or "TBD — use our typical range"]
- Key goals: [what the client wants to achieve]
- Any special requirements: [list]
Please draft a complete event proposal with: Executive Summary, Event Overview, Our Approach, Scope of Services, Investment Breakdown, and Why [Your Agency Name].
What you should see: A full proposal draft in about 30 seconds that already reflects the client preferences you stored in the project instructions.
After reviewing the draft, use follow-up prompts to sharpen specific sections:
Once satisfied, ask: "Reformat this as clean markdown with clear section headers, ready to paste into a Word document." Copy the output into your proposal template in Word or Google Docs, add your agency branding, and export to PDF.
For a first-time client:
Write an event proposal for a new client in [industry]. Event: [type], [headcount] people, [date], [city]. Budget: [amount]. Goals: [list]. Tone: professional and confident. Include an "About Us" section that establishes credibility.
For a repeat client:
Using what you know about [client name] from this project, draft a proposal for [event type] on [date]. New details: [headcount, budget, any changes from past events]. Reference our past work together in the Why Us section.
For a competitive bid:
This is a competitive RFP — we're bidding against 3 other agencies. Draft a proposal that emphasizes our unique value. Event: [details]. Make our differentiation clear without sounding defensive.
Post-proposal follow-up email:
Write a follow-up email to send 3 business days after submitting a proposal to [client]. They haven't responded yet. Keep it brief, express continued interest, and offer to answer any questions.
Budget clarification email:
Write an email asking a prospect to share their event budget range before I finalize the proposal. Be tactful — position it as needing this information to give them the most accurate investment estimate.
