Most agency quotes go wrong before the agency reads the brief. The brief says “modern, clean, conversion focused,” and three agencies return three prices for three different websites. A good brief removes that gap in one page.
A good brief saves weeks of back and forth. This guide gives you a ten line template, a side by side of weak and strong briefs, the questions agencies wish you had answered and a checklist to run before you hit send.
Key takeaways
A design brief for SaaS is a decision document. It should say what you want to change, for whom and how you will know it worked.
Use the Ten Line Brief. Ten short answers beat ten pages of background.
Give a budget range. Agencies cannot propose the right scope without it, and it makes quotes comparable.
State the buyer, the problem and the proof you have. Do not leave positioning for the agency to guess.
Send the brief to three agencies, and ask each to answer the same questions.
What is the Ten Line Brief?
The Ten Line Brief is a one page SaaS website brief template with ten short answers. Each line forces a decision that an agency would otherwise have to guess.
# | Line | The question it answers |
|---|---|---|
1 | Company | What do you do, in one sentence? |
2 | Buyer | Who buys, and who uses? |
3 | Problem | What is wrong with the current site? |
4 | Goal | What should change, and how will you measure it? |
5 | Scope | Which pages and features are in and out? |
6 | Proof | What evidence do you have for the story? |
7 | Constraints | Platform, integrations, brand, legal |
8 | Timeline | When must it launch, and why? |
9 | Budget | What range have you set? |
10 | Team | Who decides, who reviews, who provides content? |
Each line of the Ten Line Brief matches a question agencies ask on the first call. Answering them upfront saves two calls and produces a more accurate quote.
Pro tip: Write line 4 first. If you cannot state the goal and the measure, no design will satisfy you, because nobody will know what satisfying means.
How to brief a design agency for a SaaS website: what should each line say?
Each line should be short, specific and checkable. Use this guide to fill in your own.
1. Company. One sentence: what you sell, to whom, and the category. Example format: “[Product] is a [category] for [buyer] that [outcome].”
2. Buyer. Name the buying role and the day to day user. A SaaS sale often has both, and the site must speak to each.
3. Problem. Describe what is broken, with evidence. “Visitors leave the homepage without clicking” is a problem. “It looks dated” is an opinion.
4. Goal. State the change and the measure: more demo requests, a higher trial start rate, a shorter sales cycle. Include today’s number if you have it.
5. Scope. List the pages: homepage, product pages, pricing, case studies, blog. State what is out of scope, such as the app itself.
6. Proof. Customer names you may use, numbers, reviews, awards. Mark what is cleared for publication.
7. Constraints. Platform preferences, required integrations, brand rules, legal or compliance requirements.
8. Timeline. A launch date and the reason it matters, such as a funding announcement or a conference.
9. Budget. A range, not a secret. Agencies use it to propose the right scope.
10. Team. Name the decision maker, the reviewers and who writes or approves content.
Pro tip: Read your brief aloud to someone outside the company. Wherever they ask “meaning what?”, you have found a line an agency will have to guess.
Why should you include your budget in the brief?
Include a range because it lets agencies propose a scope that fits, and it makes quotes comparable. Without a budget, agencies guess, and the gap between guesses is wide.
Clutch’s pricing guides show how wide published ranges are. Its UX pricing guide, updated September 21, 2026, says most reviewed UX projects cost $10,000 to $49,999, and its web design guide says most reviewed projects cost under $10,000 while the average is $38,105. A buyer with no budget cannot tell which of those bands an agency is quoting in.
Hiding the budget rarely gets you a lower price. It tends to get you a range of scopes that are hard to compare. If you are unsure, give a range and ask each agency what they would deliver at the low and the high end.

What does a weak brief look like next to a strong one?
A weak brief describes taste. A strong brief describes decisions.
Line | Weak | Strong |
|---|---|---|
Company | “A leading AI platform” | “An AI phone agent for hospital call centers” |
Buyer | “Businesses” | “Call center managers at health systems, and the IT lead who approves” |
Problem | “Our site looks outdated” | “Visitors leave the homepage within seconds, and sales explains the product on every call” |
Goal | “More leads” | “Raise demo requests from 40 to 60 a month by Q2” (illustrative) |
Scope | “Full redesign” | “Homepage, 3 product pages, pricing, 6 case studies, blog template” |
Proof | “Many happy customers” | “4 named customers cleared, 1 case study with a number” |
Budget | “Flexible” | “$25,000 to $40,000” (illustrative) |
The weak column contains real sentences we see in briefs. The strong column’s numbers are illustrations to show the level of detail, not benchmarks.
What do agencies wish you had answered?
Agencies most often wish briefs answered these five questions.
What is the real problem? Is it the design, the message, the platform or the traffic?
Who decides? Many projects stall because three people each have a veto.
What content exists? Copy, images, case studies and product screens are often assumed to exist.
What has been tried? Past redesigns, tests and agencies tell the agency what not to repeat.
What happens after launch? Who maintains the site, and how will updates be made?
If you are not sure whether your problem is messaging or design, say so in the brief. A good agency can scope a short discovery phase, and that is better than building on a guess.

How do you compare responses to your brief?
Ask each agency to answer the same questions, then compare side by side.
Question to ask | What a strong response looks like |
|---|---|
What would you do first? | A clear first phase, such as positioning or audit |
Who works on this? | Named people, roles and seniority |
What is in and out of the price? | A written list of inclusions and exclusions |
How do you handle revisions? | Rounds defined, with cost beyond |
What do you need from us? | A specific list with dates |
How will we know it worked? | A measure tied to your goal |
Look for agencies that challenge your brief respectfully. An agency that questions line 3 or line 4 is thinking about your problem. One that accepts everything may be thinking about the proposal.

What are the most common brief mistakes?
These are the six mistakes to avoid when you learn how to write a website redesign brief.
Describing taste, not goals. “Modern and clean” fits every site.
Hiding the budget. It produces quotes you cannot compare.
Leaving positioning to the agency. Unless you hire for it, they will guess. April Dunford describes positioning as deciding how a product is the best in the world at delivering some value to a well defined set of customers, and an agency cannot decide that without your buyer and proof lines.
Listing every feature. A long list hides priorities.
Naming no decision maker. Feedback arrives from everyone, and nothing gets finished.
Skipping the problem. Without it, the agency solves the problem they prefer.
What should you check before you send the brief?
Run this checklist on your draft.
Does line 1 fit in one sentence?
Does line 3 contain evidence, not opinion?
Does line 4 name a measure?
Does line 5 list what is out of scope?
Is there a budget range?
Is one person named as decision maker?
Did someone outside your team read it and understand it?
If you can answer yes to all seven, send it to three agencies and ask each to answer the same questions.

Briefing a design agency FAQs
Include your company in one sentence, the buyer, the problem with the current site, the goal and its measure, the scope of pages and features, proof you can use, constraints, the timeline, a budget range and the team who will decide and review. Ten short answers on one page are better than a long document.
One page is usually enough. A short brief with specific answers beats a long one with background. If an agency needs more detail, they will ask, and the first call is the place for it. Attach supporting material, such as analytics or a sitemap, as separate files.
Yes, as a range. Agencies use it to propose a scope that fits, and it makes quotes comparable. Clutch’s published ranges are wide, so without a budget you cannot tell which band an agency has in mind. Ask each agency what they would deliver at the low and high end.
Yes. Kraftbase is a product messaging and UI/UX design studio for AI and B2B SaaS companies, and a SaaS UI UX design agency. If your problem might be messaging rather than design, we can run a short discovery phase to sharpen the brief before scoping the project.
A brief is a short description of the problem, goal and constraints, used to start a conversation. An RFP for SaaS website design is a longer, more formal document that asks vendors to respond to set questions and often follows a procurement process. For most SaaS companies, a one page brief and a call work better.
Three is a good number. It gives you a range to compare without creating a large amount of work for you or for them. Send the same brief and the same questions to each, and compare their answers side by side.
The person who owns the goal, usually a founder or head of marketing, with input from sales and product. Sales knows how buyers describe the problem, and product knows what the product does. One named owner should hold the pen so the brief has a single voice.
