The single biggest cause of disappointing website projects isn't bad designers or bad code — it's a vague brief. If you don't know exactly what you want the site to do, no agency can read your mind, and you'll end up paying to discover that mid-project. Learning how to write a website brief that's clear and honest is the highest-leverage hour you'll spend on the whole project. It gets you accurate quotes, comparable proposals and a finished site that actually does its job.
The good news: a great brief doesn't need to be long or technical. It needs to be clear. Here's a practical, jargon-free structure you can follow, built from years of reading briefs that worked and briefs that didn't.
Start with the why, not the what
Most briefs jump straight to features — "I need a blog, a gallery and a contact form." That's putting the cart before the horse. A good brief starts with the business goal, because the goal determines every decision that follows.
Ask yourself: what does success look like? "More qualified enquiries from local builders" is a goal. "A modern-looking website" isn't — it's a vague wish that's impossible to deliver against or measure. Be specific:
- Generate leads? Then the whole site bends towards clear calls to action and easy contact.
- Sell products online? Then payments, stock and delivery shape everything.
- Build credibility to support your sales team? Then proof, case studies and professionalism lead.
- Reduce admin by letting customers self-serve? Then functionality matters more than gloss.
Nail the goal and the rest of the brief practically writes itself.
Describe your audience honestly
A site for retired customers in rural Suffolk should look and behave very differently from one aimed at twenty-something tech buyers. Tell the agency who you're actually trying to reach: roughly who they are, what problem brings them to you, and whether they'll mostly be on a phone or a desktop. The clearer the picture, the better the decisions everyone makes on your behalf.
Spell out what the website must do
Now you can talk features — grounded in the goal. List the functionality you genuinely need, and be honest about must-haves versus nice-to-haves, because that distinction directly controls your budget.
A practical features checklist
- Core pages: roughly how many, and what they are (home, services, about, contact, etc.).
- Contact and enquiry: simple form, online booking, live chat?
- Selling: are you taking payments or bookings online?
- Content updates: do you need to edit pages yourself, or will the agency handle changes?
- Integrations: must it connect to your CRM, accounting software, or a mailing list?
- Special functionality: a members' area, a calculator, a searchable directory — anything unusual to your business.
You don't need to know how any of it gets built. That's the agency's job. You just need to describe what you need it to do. If you're unsure whether something's realistic, say so — a good partner will tell you honestly. Our web design service is built around having exactly that conversation before a line of code is written.
Be upfront about budget and timeline
This is the section people most want to dodge, and it's the one that helps most. Withholding your budget doesn't get you a better deal — it just wastes everyone's time with proposals that miss the mark, high or low.
You don't need a precise figure. A range is plenty: "we're thinking somewhere between five and ten thousand" lets an agency design a solution that fits, and tell you honestly what's achievable within it. A reputable agency won't simply spend your whole budget regardless; they'll recommend the right scope and explain the trade-offs. You can sense-check expectations against our pricing page before you even start writing.
On timelines
If there's a real deadline — a trade show, a product launch, a seasonal peak — say so clearly and explain why. If there isn't, be honest about that too. A fabricated "ASAP" helps nobody and can quietly inflate costs.
Don't try to design it yourself
A common trap for the well-intentioned is over-specifying the solution. The brief fills up with instructions about exact colours, where each button should sit, and which font to use — and in doing so it ties the hands of the very experts you're paying for. You've hired a design agency for their judgement; a brief that dictates every pixel throws that judgement away.
The healthier division of labour is this: you are the expert on your business, your customers and your goals. The agency is the expert on how to translate those into an effective website. Tell them what you need to achieve and why, share the styles you're drawn to, and then trust them to recommend how. The best results come from that partnership, not from a client trying to do the designer's job and the designer simply executing orders they suspect are wrong.
Leave room for expertise
Some of the most valuable things an agency offers are the suggestions you didn't ask for — a smarter structure, a feature you hadn't considered, a warning that something you wanted will frustrate your users. A brief that's clear on goals but open on execution invites that expertise. A brief that's a rigid spec shuts it out.
Provide the practical bits
A few supporting details turn a good brief into one an agency can quote accurately straight away:
- Examples you like — two or three websites (competitors or not) and a sentence on what you like about each. "I like how clear their navigation is" is far more useful than "it looks nice."
- Examples you dislike, for the same reason — knowing what to avoid is half the battle.
- Your assets — do you have a logo, brand colours, photography and written content ready, or will you need help creating them? This significantly affects scope and cost.
- Who decides — name the one person with final sign-off. Projects run by committee with no clear decision-maker are where timelines and budgets quietly go to die.
A simple brief template
Pulling it together, a brief that gets results answers these questions in plain English:
- Who are we and what do we do?
- What's the single main goal of this website?
- Who is our target audience?
- What must the site be able to do? (must-haves vs nice-to-haves)
- What's our rough budget range?
- Is there a genuine deadline, and why?
- Which sites do we like and dislike, and why?
- What assets do we already have?
- Who has final sign-off?
Answer those nine honestly and you've got a brief that lets any agency give you an accurate, comparable quote — and gives you a website built to achieve something specific, not just to look modern.
