Client Brief Template

A client brief template gives your agency one place to capture what a client needs before any work starts. Account managers and project leads fill it in at kickoff, so the client and the internal team agree on goals, scope, and deadlines from day one. This free template keeps the project details, goals, and requirements together in a single doc.

What is a client brief template?

A client brief is a short document that sums up a client project before the work begins. It records who the client is, what they want to achieve, who the work is for, and the practical limits like budget and deadlines. A client brief template gives you the same structure for every project, so every project captures the same information, even when a new account manager takes over.

Agencies use the brief to turn a kickoff conversation into something the whole team can refer back to. The brief gives everyone a shared reference when decisions need to be made, which cuts down on back-and-forth emails. Keep it clear and concise. One or two pages is usually enough. If a section needs more detail, link to a separate doc instead of making the brief longer.

What does a client brief template include?

A client brief template covers the project overview, background, goals, audience, deliverables, guidelines, timeline and budget, and contacts. Start with these and add anything your agency always needs.

Client and project overview

The client's name, company, main contact, and a two or three sentence summary of the project. Anyone who opens the brief should understand the job in under a minute.

Background and problem

Why the client is starting this project now. Note what they tried before and what did not work.

Goals and success metrics

What the project needs to achieve, written as outcomes. Add how you will measure success, for example sign-ups, leads, or launch date met.

Target audience

Who the work is for. Include their role, needs, and where they will see the work. If the client has customer research or personas, link to them here.

Deliverables

The exact list of what the agency will hand over, with formats and quantities. For example, "three homepage concepts in Figma" instead of "website design".

Client guidelines

Brand guidelines, tone of voice, and any must-haves or no-gos. Link to the brand assets so the team does not have to ask.

Timeline and budget

Key dates, milestones, review rounds, and the agreed budget. Note any hard deadlines like an event or product launch, and how the budget is split if there are several phases.

Contacts and approvals

Who is involved on both sides and who gives final sign-off. Name one decision maker on the client side.

Agency brief and creative brief: how they relate

Agencies often use a few kinds of brief. They overlap, and one template can cover more than one.

Client brief

Written at kickoff, often with the client. It captures the business need, scope, budget, and timeline. It is the agreement both sides work from.

Agency brief

The internal version the account team writes for the people doing the work. It translates the client's needs into tasks, owners, and priorities. Many agencies keep it as a section of the client brief, so both are updated together. Add internal notes here, like which team members are assigned and how many hours each task should take.

Agency creative brief

Focused on the creative work itself: the message, the audience insight, and the execution strategy. Use this template as an agency creative brief by making sure it covers three things: the client's guidelines, the target audience, and the execution strategy. For a deeper guide, read our article on how to write a creative brief. If the project is mostly visual or video work, the creative brief template, graphic design creative brief, and video production creative brief go into more detail.

How to write a client brief

You can fill in a brief in under an hour if you prepare well. These steps work for most agency projects.

1. Do your homework before the kickoff call

Read the client's website, past campaigns, and any request for proposal they sent. Fill in what you already know so the call can focus on the gaps. Check whether your agency has worked with this client before, and read the old brief if there is one.

2. Run the kickoff with the template open

Go through the sections in order and ask the questions out loud. Write answers in the client's own words where you can. Note open questions instead of guessing. Useful questions to ask:

• What made you start this project now?
• What does a great result look like six months after launch?
• Who needs to approve the work, and how fast can they reply?
• What have you seen from competitors that you liked or disliked?
• What would make you call this project a failure?

3. Turn goals into measurable outcomes

Ask what number would make the client happy, and by when. If there is no number, agree on a clear finish line.

4. Pin down deliverables and limits

List every deliverable with its format, the number of review rounds, and the deadline. Write down what is out of scope too, for example extra languages, stock photos, or social media versions.

5. Send it back for sign-off

Share the brief with the client within a day of the kickoff. Ask the named decision maker to confirm it in writing, or to comment on anything that is wrong. Do not start production until you have that confirmation.

6. Share it with your team and keep it current

Once approved, share the brief with everyone on the project. If the scope changes, update the brief and note the date and reason. Tip: add a short change log at the bottom so people can see what moved.

What can a client brief template do for me?

• Faster kickoffs. Your team asks the same questions every time, so calls are shorter and nothing is missed.
• Fewer revisions. Clear goals, audience, and guidelines mean the first draft is closer to what the client wants.
• Less scope creep. A signed list of deliverables and exclusions makes extra requests easy to spot and price.
• Easier handovers. When someone joins the project or goes on holiday, the brief tells them everything they need.
• Better estimates. Past briefs show how long similar projects took, which helps you price the next one.
• A shared reference. When a decision comes up, the team checks the brief instead of digging through emails.

Keeping briefs in a shared workspace also helps them stay accurate over time. Slite's self-maintaining documentation flags docs that go out of date, so old briefs do not mislead the next project.

How can I get started with the free client brief template?

Duplicate the template into your Slite workspace and make a new copy for each client project. Fill it in during or right after the kickoff call, while the details are fresh. Share it with the client to confirm you understood them correctly, then with your team so everyone starts from the same information. Update it whenever the scope changes, so the brief stays the one place to check what was agreed.
