Agency time is finite. When a brief is unclear, agencies spend that time making assumptions — often the wrong ones. The result is revision cycles, timeline blowouts, and creative that feels close but never quite right. The single most effective thing a client can do to improve their agency output is learn to brief well.
1. The objective — in one sentence. What does this piece of work need to achieve? Not what it needs to look like — what it needs to do. "Increase qualified leads from property investors" is a better objective than "create a campaign for our new development."
2. The audience — specifically. Not "professionals aged 30–55." Give your agency the real person: their life stage, their motivations, their objections. The more specific you are, the more targeted the creative.
3. The message — one thing. If the audience takes away one thing from this piece of work, what is it? Resist the urge to communicate five things at once. The best campaigns say one thing, clearly.
4. The tone — with examples. Describe the tone in adjectives, then back it up with references. "Confident but not arrogant, warm but not casual" gives an agency direction. Adding "think Aesop, not Bonds" makes it concrete.
5. The deliverables — specifically. List every asset: format, size, platform, quantity. Don't assume the agency knows what a "social campaign" means to you.
6. The timeline — with the real deadline. Tell the agency when you actually need it, not when you'd ideally like it. And flag any hard deadlines like event dates or media bookings.
7. The budget — honestly. Sharing your budget doesn't give agencies permission to spend it all. It allows them to propose work that's actually achievable with what you have.
Copy and use this for any creative project:
Project name:
Date of brief:
Due date:
Objective: What does this work need to achieve? (One sentence)
Audience: Who is this for? Be specific.
Key message: If they remember one thing, what is it?
Tone: Describe in 3 adjectives + provide 2 reference examples
Deliverables: List every asset with format, size and quantity
Budget: Total available budget
Hard deadline: The real, immovable date
Approver: Who signs off on final work?
What we've tried before: What has/hasn't worked
Mandatory inclusions: Logo lock-ups, legal copy, URLs, etc.
Briefing by committee. When five people contribute to a brief and nobody reconciles the conflicts, the agency gets contradictory direction. Nominate one brief owner and have them resolve internal tensions before sharing with the agency.
Leading with the execution, not the problem. "We need a video" is not a brief. "We need to communicate X to Y audience in order to achieve Z" is. Let the agency recommend the execution — that's what you're paying them for.
Changing the brief mid-project. If the brief changes, the scope changes. Be transparent with your agency when direction shifts and expect a conversation about timelines and cost.
One to two pages is ideal. A brief that's too short leaves too many assumptions open. A brief that's too long often buries the most important information. The template above covers everything an agency needs in a scannable format.
Yes — but frame them carefully. "We like how Brand X does Y" is useful. "We want to look like Brand X" gives the agency less room to create something differentiated. Use competitor references for context and direction, not as a blueprint.
Give the agency a range. "We're thinking $10,000–$20,000" is far more useful than no figure at all. It allows the agency to scope appropriately and flag early if the ambition exceeds the budget.
After every major project. A 15-minute debrief on what worked and what could be clearer in the brief will improve your agency relationship over time. The best client-agency partnerships develop a shared briefing language that makes every project faster.
