How to Write a Software Project Brief That Gets Accurate Quotes

The quality of the proposals you receive depends on the quality of the brief you send. A vague brief produces quotes that vary wildly, because each team is pricing a different imagined project. A clear brief produces comparable proposals and an estimate you can trust.

What to include

1. Background

Who you are, what your company does and why this project matters now. Two or three short paragraphs.

2. The problem

Describe the problem you are solving, not the solution you imagine. "Our support team spends hours each day answering order status questions" is more useful than "we need a chatbot". The problem lets teams propose better solutions.

3. Users

Who will use the product? Customers, staff, partners, administrators? What do they need to accomplish? Where are they (US, UK, Europe, Australia, worldwide) and on which devices?

4. Key workflows

Describe the three to five most important things users must be able to do, step by step, in plain language. These matter more than a long feature list.

5. Features: must-have vs nice-to-have

Split features into two lists. Must-haves are what the first version cannot launch without. Everything else is nice-to-have. This split is the single biggest factor in cost and timeline.

6. Integrations and existing systems

List the systems the product must connect to: CRM, ERP, payment providers, identity providers, data warehouses, existing apps. Mention whether they have APIs.

7. Platforms

Web, iOS, Android, desktop, game consoles, VR? Which browsers and devices must be supported?

8. Design

Do you have brand guidelines, existing designs or a design system? Do you need UX research and design as part of the project?

9. Data, security and compliance

What data will the system handle? Are there requirements such as GDPR, HIPAA, SOC 2, accessibility standards (WCAG) or data residency? For AI projects, mention any concerns about data use by model providers and the EU AI Act if you serve Europe.

10. Constraints

Budget range, desired launch date, fixed external deadlines (an event, a funding round, a season), and any technology preferences or restrictions.

11. Success measures

How will you know the project worked? Fewer support tickets, faster processing, more sign-ups, revenue, retention?

12. Process and contacts

Who makes decisions, who will be the day-to-day contact, how you want to receive proposals and by when.

What to leave out

• Long technical specifications written before talking to engineers.
• Prescribed technologies, unless there is a real constraint.
• Every possible future feature. Mention the long-term vision briefly, but keep the brief focused on the first release.

Specific advice for AI and game projects

AI projects: include sample data (anonymized if needed), examples of good and bad outputs and how accuracy will be judged. See how to build an AI assistant.

Game projects: include the core loop, reference games, target audience, platforms, monetization model and art style references. See the game development process.

Then talk

A brief starts a conversation; it doesn't replace one. The best proposals come after a call where the team asks hard questions. If a team sends a fixed quote without asking anything, treat that as a warning sign. See questions to ask before you hire a development partner.
