TL;DR: Agencies get dozens of project inquiries per month. The briefs that get serious attention share four things: a clear business problem, honest constraints, a budget range, and the right level of detail — enough to estimate, not so much that it prescribes the solution. Here's a template and the reasoning behind each section.
Why your project brief matters more than you think
The brief is your first impression with the agency. It tells them whether you've thought about your project seriously, whether you'll be a good client to work with, and whether they can deliver what you need.
Agencies evaluate your brief the same way you evaluate their proposal. A brief that's vague, disorganized, or missing key information signals that the project will be disorganized too. Top agencies will pass on these opportunities because they know the patterns that lead to project failure.
A clear, honest brief attracts better proposals. Period.
What to include: section by section
1. One-paragraph summary
Start with a plain-English summary that anyone in the agency can understand — from the CEO to the developer.
Bad: "We need a comprehensive digital transformation platform leveraging cloud-native architectures to enable omnichannel customer engagement."
Good: "We run a logistics company with 200 drivers. Dispatchers currently manage routes manually using spreadsheets and phone calls. We need a web app for dispatch and a mobile app for drivers, replacing this manual process."
One paragraph. What you do, what problem you're solving, what you want built.
2. Business context
Explain why this project exists now. Agencies use this to understand your urgency, priorities, and what success means to your organization.
- What triggered this project? (Growth, regulatory requirement, competitor pressure, operational pain)
- What happens if you don't build this? (Competitor gains, compliance risk, continued operational costs)
- Who are the end users? (Internal team, customers, partners)
- How many users, approximately?
3. What you want built (problem-first, not solution-first)
Describe the problem each feature solves, not the feature itself.
| Instead of this | Write this |
|---|---|
| "Dashboard with KPIs" | "Dispatchers need to see which routes are running late and which drivers have capacity, updated in real time" |
| "Integration with SAP" | "When a new order is created in SAP, a delivery task should automatically appear in the dispatch queue within 5 minutes" |
| "Push notifications" | "Drivers need to be alerted when a new delivery is assigned or a route changes, even when the app is in the background" |
| "Admin panel" | "Operations managers need to add/remove drivers, modify zones, and view historical delivery data without developer help" |
This approach invites the agency to propose the right solution instead of executing your feature list. The agency may have built similar systems and know shortcuts or better patterns you haven't considered.
4. Priorities — what's essential versus what's nice to have
Not every feature has the same value. Use a simple two-tier system:
Must-have for launch: - Real-time dispatch dashboard - Driver mobile app with GPS tracking - Route assignment and status updates - SAP integration for order ingestion
Nice-to-have (post-launch iteration): - Automated route optimization - Customer-facing delivery tracking portal - Historical analytics and reporting - Driver performance scoring
This tells the agency how to scope their proposal. A $100K budget can cover the must-haves; a $250K budget can cover everything. Without priorities, the agency has to guess what matters most.
5. Technical context and constraints
Share what the agency needs to estimate accurately:
- Existing systems: What does the new system need to connect to? (ERP, CRM, payment processor, existing APIs)
- Technology constraints: "Must run on AWS" or "We have an existing React frontend that needs to be extended" — valid constraints. "Must be built in Python" without a reason — not helpful.
- Security and compliance: GDPR, HIPAA, SOC 2, ISO 27001. State what's required so agencies can scope the compliance work.
- Hosting and infrastructure: Cloud provider preference, on-premise requirements, data residency rules.
Important: share constraints, not mandates. "Must integrate with our PostgreSQL database" is a constraint. "Must use NestJS with TypeORM" is a mandate that eliminates agencies who'd deliver better with different tools.
6. Budget range
We wrote an entire section about this in our RFP guide, but here's the short version:
Always share a budget range. Not the ceiling. A range.
"We've budgeted $80,000-150,000 for the initial build and plan $5,000-10,000/month for ongoing support."
Without this, agencies either guess wrong (wasting everyone's time with a mismatched proposal) or pad their estimate heavily to cover the unknown.
7. Timeline
State what's driving the timeline:
- "Hard deadline: regulatory requirement kicks in January 1"
- "Soft target: we'd like to start beta testing by Q3, but two months of flexibility exists"
- "No fixed deadline, but we want to see progress within 30 days of signing"
If you don't have a deadline, say so. Artificial urgency leads to artificial estimates.
8. How you want to work
A few sentences about your working style helps agencies assess fit:
- "Our team is based in Tel Aviv, working 9-6 Israel time"
- "We prefer async communication with weekly sync calls"
- "Our product owner has 5-10 hours per week to dedicate to this project"
- "We've worked with external teams before / this is our first time"
9. What you want back from the agency
Tell agencies what to include in their response:
- How they'd approach the project
- Estimated timeline with milestones
- Team composition (roles and experience levels)
- Pricing structure (fixed, T&M, or hybrid)
- Two relevant portfolio examples
- References from similar projects
What to leave out
| Leave out | Why |
|---|---|
| Pixel-perfect mockups | You're hiring experts — let them propose the UX |
| Technology mandates without rationale | Limits the agency's ability to recommend the best approach |
| 40-page requirements documents | Save the detailed specs for the discovery phase |
| Internal politics and org-chart drama | The agency needs the business problem, not your org dynamics |
| Competitor analysis and market research | Share this during discovery, not in the brief |
The brief quality test
Before sending your brief to agencies, run this test:
- Can a stranger understand it in 10 minutes? If yes, it's the right length and clarity.
- Does it answer "why" before "what"? Business context before features signals you've thought about the problem.
- Is the budget disclosed? No budget = agencies either pass or waste time asking.
- Are priorities clear? Must-have vs nice-to-have helps agencies scope accurately.
- Is it under 5 pages? The discovery phase handles details. The brief handles direction.
How Globalbit responds to project briefs
We read every brief within 24 hours. If the project fits our expertise (web/mobile development, AI, enterprise systems), we schedule a 30-minute call to ask our own questions — because a brief alone never tells the full story.
Our proposal comes back within 5-7 business days and includes: proposed approach, team composition, estimated timeline, and two relevant portfolio references. We don't do generic proposals. If we respond, it's because we believe we can deliver.
If you're preparing a project brief and want a second opinion before sending it out, we'll review it at no cost.
Frequently asked questions
Should I send the same brief to every agency on my shortlist? Yes. Consistent briefs produce comparable proposals, making evaluation much easier. Customize only the cover note, not the content.
How many agencies should I send my brief to? Three to five. You need enough proposals to compare options, but not so many that evaluation becomes a second full-time job. Pre-qualify agencies before sending the brief.
What if I don't know enough to write a technical section? Leave it out and say so. "We don't have a technical team — we need the agency to recommend the architecture" is perfectly valid and helps the agency scope their proposal correctly. Pretending to know technology requirements when you don't leads to worse outcomes than admitting you need guidance.
Should I pay for a discovery phase before the full project? Almost always yes. Discovery (2-4 weeks, typically $5,000-15,000) transforms a vague brief into a detailed project plan. It also tests the working relationship before you commit to a full engagement. Most successful projects we deliver at Globalbit start with paid discovery. Ask us about our process.
