Write the requirement in business language
Start with the people and the problem: retail counters, service firms and small offices need to issue consistent invoices and follow payments because manual billing leads to errors and slow receipt tracking. 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
- Customer master
- Item and rate selection
- Invoice
- Payment receipt
- Outstanding follow-up
Section 3: outputs and acceptance samples
- Invoice register
- Collection summary
- Receivables ageing
- Customer ledger
Section 4: business rules and exceptions
- Tax configuration
- Credit limits
- Print format
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 invoice correction rate after launch to judge whether the project achieved its intended purpose.
