Event Brief Template
What is an event brief, and what should it include?
An event brief is a short document that tells the people planning an event what it is for and what it has to do. It is written before the planning starts, by whoever owns the event, and handed to an in-house team, an agency or a freelance planner. A good brief saves weeks of back and forth because the answers to the first twenty questions are already on the page.
The brief is not the plan. It states the goals, the audience, the limits and what success looks like, and leaves the planner room to propose how. Use the template below to write yours, and the section on writing it for the points that make a brief useful instead of just complete.

What an event brief includes
Keep it to one or two pages. A brief nobody reads in full is worse than a short one that everyone does. These are the parts most briefs need:
| Part | What it answers | Why the planner needs it |
|---|---|---|
| Background | Who we are and why we are holding this event | Sets the context and the tone |
| Goals and measures | What the event must achieve, and how success is judged | Every decision is tested against it |
| Audience | Who will attend, how many and what they care about | Drives format, content and venue |
| Format and date | In person, virtual or hybrid, length, dates, location preferences | Defines the shape of the plan |
| Programme ideas | Sessions, speakers, activities, sponsors or exhibitors we already have | Shows what is fixed and what is open |
| Budget | The total, what it covers and what is excluded | Stops proposals that cannot be afforded |
| Constraints | Brand rules, accessibility, approvals, sustainability, venue limits | Avoids rework |
| Responsibilities | Who decides, who approves, who is the day-to-day contact | Keeps the decisions moving |
| Timeline | Key dates: proposal, approval, announcement, event, report | Gives the planner a schedule to work to |

Copy the text below. Where you do not know an answer yet, write that down rather than leaving the line out, so the planner knows what to help you decide.

How to write a brief that works
A complete brief is not always a useful one. These habits make the difference:
Lead with the goal, not the idea
If the brief says "a gala dinner" before it says what the event is for, you will get gala dinners. State the outcome and let the planner propose the format.
Be honest about the budget
A planner who knows the real figure designs for it. Hiding it wastes proposals on both sides.
Separate fixed from open
Say what cannot change, such as the date or the keynote, and what you want advice on. It tells the planner where creativity is welcome.
Name one decision maker
A brief that goes to five approvers produces five sets of changes. Name who decides and who only comments.
Say what success looks like
Give the number or the outcome. It lets you judge proposals and, later, the event.
Share what you learned
If there was a previous event, say what worked and what did not. It is the most valuable page you can add.

FAQ
Event Brief Template: common questions
What is an event brief?
A short document that states what an event is for, who it is for and the limits it has to work within, written by the event owner for the people who will plan it.
How long should an event brief be?
One to two pages is usual. Long enough to answer the planner's first questions, short enough that everyone reads it. Attach brand guidelines and past reports instead of pasting them in.
Who writes the event brief?
The person who owns the event and its budget, with input from the stakeholders who will approve it. The planner or agency may ask questions to sharpen it, but the goals should come from the owner.
What is the difference between an event brief and an event proposal?
The brief comes from the client and says what is needed. The proposal comes from the planner in response and says how they would do it, at what cost.
Does Eventdex have an event brief feature?
No. Eventdex does not create or store briefs. It provides the planning, registration, check-in and reporting tools you build and run the event with after the brief is agreed.
