## ⚡ Quick Guidelines
- ✅ Focus on WHAT users need and WHY
- ❌ Avoid HOW to implement (no tech stack, APIs, code structure)
- 👥 Written for business stakeholders, not developers

### Section Requirements
- **Mandatory sections**: Must be completed for every feature
- **Optional sections**: Include only when relevant to the feature
- When a section doesn't apply, remove it entirely (don't leave as "N/A")

### For AI Generation
When creating this spec from a user prompt:
1. **Mark all ambiguities**: Use [NEEDS CLARIFICATION: specific question] for any assumption you'd need to make
2. **Don't guess**: If the prompt doesn't specify something (e.g., "login system" without auth method), mark it
3. **Think like a tester**: Every vague requirement should fail the "testable and unambiguous" checklist item
4. **Common underspecified areas**:
   - User types and permissions
   - Data retention/deletion policies  
   - Performance targets and scale
   - Error handling behaviors
   - Integration requirements
   - Security/compliance needs

## Clarifications

### Session 2025-10-04
- Q: What authentication method should the platform use for user access? → A: All methods support

## User Scenarios & Testing *(mandatory)*

### Primary User Story
As a Malaysian SME business owner, I want to access industry-specific business management modules through a subscription-based SaaS platform so that I can streamline my operations without investing in expensive custom software or IT infrastructure.

### Acceptance Scenarios
1. **Given** a new business owner wants to register, **When** they receive an admin registration link and complete business details, **Then** the system creates an isolated tenant space pending approval
2. **Given** an admin approves a tenant registration, **When** approval is processed, **Then** the tenant receives credentials and can access subscribed modules
3. **Given** a retail business user has subscribed, **When** they access their tenant dashboard, **Then** they can only use Retail & Food Stall modules based on their subscription plan
4. **Given** a healthcare clinic has subscribed, **When** they access the system, **Then** they can manage patient records, appointments, and billing through their dedicated module
5. **Given** a business wants to change pricing models, **When** they request to switch from subscription to perpetual license, **Then** the system calculates the buyout price based on subscription payments made

### Edge Cases
- What happens when a tenant exceeds their subscription module limits?
- How does system handle concurrent access within the same tenant organization?
- What happens if a tenant's subscription payment fails?
- How does system ensure data isolation between tenants during peak usage?
