A requirements document does not need fifty pages. Its purpose is to give a developer enough context to understand the problem, propose a solution and estimate a precise scope. A short, coherent brief is better than a long list of conflicting ideas.
The structure below works for a showcase site, e-commerce store, mobile app or internal tool.
1. Introduce the business and problem
Explain your business, audience and current workflow. Then describe the concrete problem: enquiries are scattered across channels, tracking happens on paper, customers cannot find information or staff repeat the same task each day.
“I want an app” assumes a solution. “I want to reduce order-processing time” describes an outcome the provider can analyse and measure.
2. Define the goals
- Receive more qualified enquiries from Google.
- Let customers book without calling.
- Reduce data-entry errors and processing time.
- Sell across several cities or languages.
- Give the team a clear view of operations.
Choose one primary goal and two secondary goals. This hierarchy supports good decisions when a feature must wait to keep the budget under control.
3. Describe users and journeys
List each role: visitor, customer, seller, courier, administrator or employee. For each role, state what they view, create, edit or approve. Include real constraints such as an older phone, a slow connection, or French, Arabic and English support.
Then tell the main stories from start to finish. For example: “The customer chooses a date, enters contact details, confirms and receives a message. The administrator sees the request and changes its status.” Five clear journeys are more useful than fifty buttons without context.
4. Prioritise features
| Level | Meaning | Example |
|---|---|---|
| Essential | The first release cannot solve the problem without it | Create an order |
| Important | Adds value but can follow later | Export a report |
| Later | An idea to test after launch | Loyalty programme |
This classification creates a coherent MVP and prevents the budget from being exhausted before observing real users.
5. Specify content and constraints
State whether the logo, copy, photography and translations exist. For e-commerce, provide product and variant counts. For an app, describe notifications, permissions and personal data. List current tools and integrations such as payment, CRM, inventory, maps or business APIs.
Provide two or three visual references and explain what you like without asking for a copy. Include privacy obligations, access roles and any rules specific to your sector.
6. Set deliverables, timing and budget
Write down what must be delivered: designs, source code, access, documentation, deployment, training and a defect-fixing period. Clarify who supplies content, creates payment or store accounts and approves each milestone.
A budget range does not weaken your negotiation; it helps the developer propose a realistic solution. Include the target date and its reason, such as a campaign, season, event or client commitment.
A checklist ready to send
- Business, audience and problem to solve.
- Primary goal and measure of success.
- Users, journeys and priority features.
- Content, languages, integrations and constraints.
- Deliverables, responsibilities, budget and schedule.
You do not need to choose the technology yourself: ask the provider to justify the approach. Explore my website development and mobile app services, or send me your draft to turn it into a clear scope.
