How to Prepare a Brief for a Development Studio
Practice4 minInnovialabs editorial team
In short
A brief is 1-3 pages on why you need the product, who it is for, what it must do, what it connects to, and what budget and deadline apply; the detailed spec comes later, together with the studio.
What a brief is and why it matters
A brief is a short document that lets a studio understand your task and give a first estimate: a suitable format, rough scope, and a range for timing and budget. The client writes it, usually in an hour or two, with no technical knowledge required.
A good brief saves time on both sides: fewer calls repeating the same questions, more accurate estimates, and easier comparison of proposals, because every contractor received the same input.
A brief is not a technical specification
| Brief | Technical specification | |
|---|---|---|
| Written by | The client | An analyst or the studio together with the client |
| Size | 1-3 pages | Dozens of pages, diagrams, prototypes |
| Answers | What and why | Exactly how it will work |
| When | Before choosing a contractor | After kickoff, during analysis |
| Outcome | Preliminary estimate | Precise estimate and work plan |
Do not try to write the spec yourself up front. Without experience you will end up with either vague text or ready-made technical decisions that may not be the best ones. In a brief it matters more to explain the problem than the way to solve it.
Brief structure
Copy these sections and answer each one in your own words.
1. Company and project
- What the business does and who the key customers are.
- What needs to be built: a website, mobile app, Telegram bot, CRM, or changes to an existing system.
- Whether anything already exists: an old site, designs, code, a domain.
2. Goals
Describe what business problem the product solves and how you will know it works. For example: "take orders online without calling a manager" or "reduce manual data entry in the warehouse". A goal like "we want a nice website" does not help estimation.
3. Audience
- Who will use it: customers, employees, partners.
- On which devices: phone, desktop, tablet.
- Which interface languages are needed.
4. Key features
List what a user must be able to do. Split the list in two:
- Required for launch — without this the product makes no sense.
- Nice to have later — can go into a second phase.
This split immediately shows the studio what belongs in the MVP.
5. References
Share 2-5 links to sites or apps you like and briefly explain what exactly you like: navigation, catalogue presentation, checkout. Links without explanations get interpreted in the studio's own way.
6. Integrations
List the systems the product must exchange data with: accounting software, payment providers, delivery services, SMS gateways, CRM, Telegram. If you do not know whether a system has an API, just name it.
7. Budget
Give a range rather than asking "how much?". A range helps the studio propose a solution that fits: for example, launching on one platform instead of two, or using ready-made components. Without a budget you will get either the minimal or the maximal option.
8. Deadline
- The desired launch date and why (season, trade show, investor meeting).
- Whether the deadline is fixed or can move.
9. Contact person
Who on the client side makes decisions and answers questions. If several people will approve the work, say so up front.
Common mistakes
- Lots of detail on small things and nothing about the goal. Button colours matter far less at this stage than user scenarios.
- Every feature is mandatory. If everything is critical, the studio cannot propose a sensible first phase.
- A hidden budget. Contractors will guess anyway, only worse.
- Technical solutions instead of problems. "We need microservices on Kubernetes" instead of "the site must handle traffic spikes during sales".
- No owner. The project stalls while nobody can answer a question.
What happens after the brief
The studio usually asks clarifying questions, suggests a format, and gives a preliminary estimate. If you proceed, the next stage is analysis: prototypes, screen and logic descriptions, the final specification, and a precise work plan.
