Software Requirements Specification Template + Example

By SayCraft Team · 2026-08-17 · 12 min read

A software requirements specification (SRS) should turn a product idea into observable system behavior. For a small app, that means recording users, scope, workflows, data, failure states, quality constraints, acceptance evidence, and unresolved decisions in one reviewable document. Use it when several people need to agree what will be built or when a quote, test plan, or handoff needs a stable boundary. It complements a product brief and user stories rather than replacing them. Copy the template below, delete irrelevant sections, and keep unknowns visible instead of inventing certainty.

# Software Requirements Specification

## 1. Purpose and decision
- Problem this product addresses:
- Decision this specification supports:

## 2. Scope
- In scope:
- Out of scope:

## 3. Users and roles
- Role:
- Goal:
- Permissions:

## 4. Assumptions and constraints
- Confirmed fact:
- Assumption to validate:
- Technical, legal, budget, or time constraint:

## 5. Functional requirements
- FR-01: When [condition], the system shall [observable behavior].
- Failure/recovery behavior:

## 6. Quality requirements
- Context:
- Measure:
- Target or threshold to confirm:

## 7. Data and integrations
- Data created/read/updated/deleted:
- Retention or privacy owner:
- External service and failure behavior:

## 8. States and errors
- Loading:
- Empty:
- Validation error:
- Permission error:
- Recovery:

## 9. Acceptance evidence
- Scenario:
- Expected result:
- Evidence owner:

## 10. Open questions and change log
- Question / owner / due date:
- Change / reason / date:

Worked example: client approval portal

Scope: a freelance designer uploads a draft, a named client reviews it, and the client approves or requests changes. Public file sharing, invoicing, and team analytics are out of scope for the first version.

Vague requirement versus testable requirement

Map database entities before adding screens

For every persistent object, record its owner, identifier, relationships, lifecycle, and deletion rule before designing screens. A client-approval portal might need Workspace, Project, Membership, Draft, Comment, and Decision. The screen is not the data model: one project can have many drafts, one draft can have many comments, and each decision must point to the exact draft version it approves.

Review checklist

• Purpose, scope, exclusions, assumptions, and the decision this SRS supports are explicit.
• Each user role has bounded permissions and at least one complete normal, failure, and recovery path.
• Data ownership, retention questions, integrations, and external-service failure behavior are visible.
• Quality requirements name a context and measure; unsupported thresholds remain marked for confirmation.
• Acceptance evidence, evidence owner, open questions, and important changes can be traced.

SRS, PRD, and user stories

A PRD explains the product outcome, evidence, scope, and tradeoffs. An SRS makes the required system behavior and quality conditions explicit. User stories package slices of user value for delivery. A small team may keep them in one document as long as each responsibility remains clear.

Before writing the document, use these requirements gathering questions. Then separate functional and nonfunctional requirements and map important risks to test evidence.

Before specifying behavior, separate business requirements from functional requirements and define the app’s user roles. If the agreed scope is going to a client, carry its assumptions into a software proposal with a worked example.
