Write the requirement in business language
Start with the people and the problem: GST registered businesses subject to e-invoicing rules need to prepare structured invoice data with validations because invoice details need extra checking before IRN workflows. A useful project brief should describe the current process before describing technical features.
Section 1: users, roles and real scenarios
List each user group, what information they create, what they can edit, what requires approval and what they can view. Add a typical busy-day scenario and an error-correction scenario.
Section 2: required steps and screens
- Invoice capture
- Gstin and hsn validation
- Irn submission integration planning
- Qr and status capture
- Reconciliation
Section 3: outputs and acceptance samples
- Irn status
- Error log
- Invoice history
- Tax review
Section 4: business rules and exceptions
- Current gst applicability
- Credential security
- Provider integration
Section 5: technology and delivery
Specify devices, hosting responsibilities, integrations where actually needed, data migration, branding, responsive behavior and any language or print constraints. Do not prescribe a technology solely because another company uses it.
Section 6: testing and sign-off
Each requirement should have a test input, an expected result and the name of an approving stakeholder. Track rejected invoice count after launch to judge whether the project achieved its intended purpose.
