The most common reason software projects run over budget isn't scope creep or bad developers. It's a vague brief that both sides interpreted differently.
When you submit a brief that says "build a marketplace like Airbnb but for X," you'll get back a quote that has a 40% padding built in to cover everything the developer imagines you might mean. When you submit a precise brief, you get a precise quote — and a much clearer project.
Here's exactly what to include.
Section 1: What the Product Does (One Paragraph)
Start with a plain-English description of what the product does for the end user. Not the technology, not the features — the outcome.
Good: "A web app that lets freelance designers upload portfolios and lets hiring companies browse and shortlist candidates without a recruiter."
Bad: "A platform with user profiles, search, messaging, and payments."
The first tells a developer what they're building and why. The second is a feature list with no context — every feature becomes a negotiation.
Section 2: Who Uses It
Describe the two or three user types. For each, write: - What they want to achieve - How technically comfortable they are - How often they'll use the product
This shapes interface complexity, error handling, and onboarding flows — all of which affect cost.
Section 3: Core User Flows (Not Features)
List the 3–5 things a user must be able to do for the product to be useful. Write them as flows, not features.
Flow (good): "A designer registers, uploads 5 portfolio pieces, sets an hourly rate, and goes live. A company searches by skill, views a portfolio, and sends a message."
Feature list (bad): "Registration, portfolio upload, search, messaging, ratings, notifications, admin panel."
Flows expose dependencies. Feature lists hide them.
Section 4: What Already Exists
If you have any of the following, list them: - Existing designs (Figma, sketches, wireframes) - A database or existing data - APIs you need to integrate with (payment gateway, CRM, email service) - An existing codebase or hosting environment - Brand guidelines
Each of these either reduces scope or constrains technology choices. A developer needs to know.
Section 5: What You're Not Building (Yet)
The most underused section of any brief. Explicitly stating what's out of scope removes the largest source of misaligned expectations.
Examples: - "No mobile app in phase 1 — web responsive only" - "No admin panel — we'll manage data directly in the database initially" - "No payments in v1 — we'll handle invoicing manually"
This signals that you've thought carefully about scope and gives the developer permission to exclude things from their quote.
Section 6: Success Criteria
How will you know the project is done? Define: - What "launch" means (feature complete? user-tested? load-tested?) - Performance expectations (how many concurrent users? page load targets?) - Any compliance requirements (GDPR, HIPAA, PCI-DSS)
Section 7: Timeline and Budget Range
Providing a budget range is not weakness — it's information. A developer who knows your budget can tell you whether the scope is achievable or what to cut to fit. Without it, they'll quote for the full scope and you'll be surprised.
"We have ₹8–12L and want to launch within 16 weeks" is more useful than "quote for everything above."
What You'll Get Back
A well-scoped brief should get you: - A fixed-price quote you can actually hold someone to, or - A well-reasoned estimate with explicit assumptions
If a vendor won't give you either after a detailed brief, that tells you something important about how they'll communicate during the project.
At SoftGodam, we turn around written quotes within 48 hours of receiving a complete brief — because a complete brief is the only way to quote honestly.
