How to Write a Software Project Brief That Gets Accurate Quotes

If you email an agency saying, "I want to build an app like Instagram for dog owners, how much will it cost?" you are going to get quotes ranging from $5,000 to $150,000.

Vague requirements lead to vague quotes. Agencies protect themselves from risk by inflating the price when they don't understand the full scope.

To get an accurate, itemized quote, you must provide a strong Software Project Brief. Here is the exact template you should use.

1. The Executive Summary

Start with the "Why." Explain the core problem your software solves and who the target audience is. Example: "We are building a mobile platform that connects local dog owners for playdates. Our target audience is millennials in urban cities. The primary goal of this MVP is to validate user engagement."

2. The Core User Flows (Not Features)

Don't just list features like "Chat" or "Profiles." Describe the journey the user takes. Example: "User Flow 1: A user opens the app, creates a profile for their dog (uploading a photo and selecting breed), and views a map of other dogs currently checked into local parks. The user can tap a pin and send a direct message."

3. Technical Constraints and Integrations

This is where agencies find hidden costs. You must list any external systems the software needs to talk to.

• Do you need to integrate with a legacy CRM like Salesforce?
• Are you processing payments? (Stripe, PayPal)
• Does the app require live GPS tracking in the background?
• Are you targeting iOS, Android, or Web?

4. Non-Functional Requirements

These define the quality of the system.

• Security: Does it need to be HIPAA compliant?
• Scalability: Do you expect 100 users on launch day, or 10,000?

5. Timeline and Budget Expectations

Be transparent. If you have a hard deadline for an investor pitch in 3 months, state it. If your absolute maximum budget is $40,000, state it. A good agency will look at your budget and your scope. If they don't align, they will use their expertise to tell you exactly which features to cut so you can hit your budget while still launching a viable product.
