How to Write a SaaS Development Brief in 2025 (Template + Examples)

You've decided to build your SaaS. You've got budget, timeline expectations, and a vision for what you want.

Now you need to explain it to developers.

This is where most founders mess up. They write vague descriptions, get wildly different quotes, pick the cheapest option, and end up with something that doesn't match what they imagined.

The problem isn't the developers. It's the brief.

A good development brief is the difference between:

• Getting 3 quotes within 20% of each other vs. quotes ranging from $15K to $150K
• Building exactly what you need vs. endless "that's not what I meant" conversations
• Launching in 10 weeks vs. a project that drags on for 6 months

I've reviewed hundreds of project briefs over 20+ years. Here's exactly what to include, with real examples and a template you can use today.

Why Your Development Brief Matters More Than You Think

Before we dive into the template, understand what a brief actually does:

For you:

• Forces you to think through requirements before spending money
• Creates a baseline for comparing quotes apples-to-apples
• Protects you legally if scope disputes arise
• Saves 20-40 hours of back-and-forth conversations

For developers:

• Shows you're serious and organized (attracts better talent)
• Enables accurate estimates instead of guesswork padding
• Reveals potential complexity early
• Sets clear expectations for both sides

A 2-hour investment in your brief can save $10,000+ in miscommunication costs.

The 9 Sections Every Development Brief Needs

1. Executive Summary (1 paragraph)

Start with a single paragraph that anyone could understand. This filters out developers who aren't right for your project and hooks the ones who are.

Include:

• What the product does (one sentence)
• Who it's for (target users)
• Core problem it solves
• Your timeline and budget range

Example:

"BuildTrack is a project management SaaS for residential construction contractors. It helps small builders (1-10 employees) track job progress, manage subcontractor schedules, and send automated client updates. We're looking to launch an MVP in 12 weeks with a budget of $35-50K."

What NOT to write:

"We're building the next big thing in construction tech. Think Asana meets Salesforce but for builders. We need a developer who shares our vision and wants to change the industry."

The first example gives developers everything they need. The second is a red flag that screams "scope creep."

2. Problem Statement

Explain the pain your users currently experience. This helps developers understand why features matter, which leads to better technical decisions.

Structure:

• Current situation (how users solve this problem today)
• Pain points (what's frustrating about current solutions)
• Cost of the problem (time, money, or frustration)
• Why existing solutions don't work

Example:

"Construction contractors currently track projects using a combination of spreadsheets, text messages, and paper schedules. This leads to:

• Missed updates to clients (causing angry phone calls)
• Double-booked subcontractors (costly delays)
• No visibility into job profitability until projects are complete
• 5-10 hours/week spent on manual coordination

Existing tools like Buildertrend and CoConstruct are designed for large contractors ($5M+ revenue) and cost $300-500/month. Our target users need something simpler and cheaper."

3. Target Users

Be specific about who will use the product. Different users have different needs, and developers need to know which ones to prioritize.

Include:

• Primary user persona (the one you're building for first)
• Secondary users (others who will interact with the system)
• Technical sophistication (are users tech-savvy or not?)
• Usage context (mobile in the field? Desktop in office?)

Example:

Primary User: Small Contractor Owner

• Runs 3-8 active jobs at once
• Age 35-55, moderate tech skills (uses smartphone but prefers simple apps)
• Needs mobile access on job sites
• Key goals: Know job status at a glance, keep clients happy, avoid scheduling conflicts

Secondary Users:

• Subcontractors (view their schedule, mark tasks complete)
• Homeowner clients (view progress updates, photos)
• Office manager (handle billing, generate reports)

4. Feature Requirements (The Core of Your Brief)

This is where most briefs fail. Either too vague ("needs to be user-friendly") or too detailed (50-page PRD for an MVP).

The right level of detail:

• Describe WHAT users need to do, not HOW it should work technically
• Prioritize ruthlessly (Must Have / Should Have / Nice to Have)
• Include acceptance criteria for key features
• Note any known constraints or requirements

Example Structure:

Must Have (MVP)

User Authentication

• Users can sign up with email/password
• Users can log in and reset password
• Admin can invite team members via email

Project Dashboard

• View all active projects in a list/card view
• See project status (Not Started, In Progress, Complete)
• Quick access to project details

Project Management

• Create new project with name, client info, address, start date
• Add tasks/phases to project timeline
• Mark tasks as complete
• Upload photos to tasks

Client Updates

• Send automated email when task is completed
• Include photos in update emails
• Client can view project status page (no login required)

Should Have (Post-MVP)

Scheduling

• Calendar view of all projects
• Assign subcontractors to tasks
• Conflict detection for double-bookings

Reporting

• Basic job profitability report
• Export to PDF

Nice to Have (Future)

• QuickBooks integration
• SMS notifications
• Mobile app (native)

5. User Flows (For Critical Features)

For your most important features, map out the step-by-step user flow. This reveals complexity you might not have considered.

Example: Client Update Flow

1. Contractor completes task in app
2. Contractor adds 1-3 photos (optional)
3. Contractor clicks "Notify Client"
4. System generates email with:
   - Task name and completion date
   - Photos (if added)
   - Link to project status page
5. Client receives email
6. Client clicks link → sees public project page
7. Project page shows: completed tasks, photos, next scheduled task

You don't need to do this for every feature—just the ones that are core to your value proposition.

6. Design & UX Requirements

Even if you're not providing designs, communicate your expectations.

Include:

• Design approach (custom design, template, developer's choice)
• Reference examples (apps/sites with UX you like)
• Brand assets (logo, colors—if you have them)
• Responsive requirements (desktop, tablet, mobile)
• Accessibility requirements (if any)

Example:

Design Approach: We'll provide Figma mockups for key screens. Developer implements the designs. No custom illustrations needed—use a clean icon library like Heroicons.

References:

• Clean, minimal UI like Linear or Notion
• Mobile-first like Jobber
• NOT: Complex dashboards like Salesforce

Brand: Logo and brand colors provided. Use Inter or similar modern sans-serif font.

Responsive: Must work on mobile (primary use case is on job sites). Desktop is secondary.

7. Technical Constraints & Preferences

If you have specific technical requirements, state them. If you don't, say so.

Things to mention:

• Existing systems to integrate with
• Hosting preferences (if any)
• Security/compliance requirements
• Scale expectations
• Technology preferences (or "open to recommendations")

Example:

Integrations: None for MVP. Future: QuickBooks Online, Google Calendar.

Hosting: No preference—open to recommendations. Needs to be reliable and affordable.

Security: Standard security practices. No specific compliance requirements (not handling healthcare or financial data).

Scale: Expecting 100 users in year 1, potentially 1,000 in year 2. Needs to handle that growth.

Technology: Open to developer recommendation. We've heard Next.js and Supabase are good for this type of app—but you're the expert.

8. Timeline & Budget

Be direct. Developers appreciate knowing the constraints upfront.

Include:

• Target launch date (and whether it's flexible)
• Budget range (not a single number—a range)
• Payment structure preferences (milestone-based, retainer, etc.)
• Decision timeline (when you'll choose a developer)

Example:

Timeline:

• Development start: January 15, 2026
• MVP launch target: April 15, 2026 (12 weeks)
• Timeline is somewhat flexible—quality matters more than speed

Budget:

• Range: $35,000 - $50,000 for MVP
• Open to proposals outside this range if well-justified

Payment: Prefer milestone-based payments tied to deliverables. Open to discussion.

Decision: Reviewing proposals through January 10. Will decide by January 12.

9. About You / Your Company

Help developers understand who they'd be working with.

Include:

• Your background (relevant experience)
• Company stage (idea, funded, revenue?)
• Team (who will they work with?)
• Communication preferences
• Decision-making process

Example:

About Us: I'm a general contractor with 15 years in residential construction. I've managed $50M+ in projects and understand the industry deeply. This is my first software product.

Company Stage: Self-funded. I'm investing my own capital. No outside investors.

Team: Just me for now. I'll be the product owner and primary decision-maker.

Communication: I prefer async communication (email, Loom videos) during the day since I'm on job sites. Available for weekly sync calls.

Decisions: I make decisions quickly. You won't be waiting days for answers.

Common Mistakes That Cost Founders Thousands

Mistake 1: Being Too Vague

❌ "The app should be intuitive and user-friendly" ✅ "Users should be able to create a new project in under 2 minutes with no training"

Mistake 2: Specifying Technical Solutions

❌ "Use React with Redux for state management and PostgreSQL with Prisma ORM" ✅ "We need a web app that's fast and maintainable. Open to your technology recommendation."

Mistake 3: No Priorities

❌ Listing 50 features with no indication of what's essential ✅ Clearly marking Must Have (MVP), Should Have, Nice to Have

Mistake 4: Hiding the Budget

❌ "We'll share budget with qualified candidates" ✅ "Our budget is $35-50K. Open to proposals outside this range if well-justified."

Mistake 5: Unrealistic Timelines

❌ "We need to launch in 4 weeks" (for a complex SaaS) ✅ "Our target is 12 weeks for MVP. What's realistic for this scope?"

What Happens After You Send the Brief

A good brief gets you better responses:

1. Fewer questions: Developers don't need 3 calls to understand your project
2. Accurate estimates: Quotes will be within 20-30% of each other
3. Better proposals: Developers will suggest improvements you hadn't considered
4. Serious candidates: Tire-kickers won't bother responding to detailed briefs

When reviewing proposals, look for:

• Did they read the brief? (Reference specific requirements)
• Do they push back on anything? (Good sign—shows experience)
• Is their estimate explained? (Not just a number)
• Do they propose a sensible approach?

The Bottom Line

A development brief isn't bureaucracy—it's protection.

Protection against miscommunication. Protection against scope creep. Protection against choosing the wrong developer because you couldn't compare proposals fairly.

Invest 2-3 hours writing a proper brief. It's the highest-ROI activity you can do before spending a dollar on development.

What your brief should include:

1. Executive summary (1 paragraph)
2. Problem statement (why this matters)
3. Target users (who you're building for)
4. Feature requirements (prioritized)
5. User flows (for critical features)
6. Design requirements (expectations)
7. Technical constraints (if any)
8. Timeline & budget (be direct)
9. About you (who they're working with)

Skip any of these, and you're gambling with your budget.

Get them all right, and you'll attract better developers, get accurate quotes, and build exactly what you need.
