5. **Capacity Planning**: Create a hiring/outsourcing roadmap indicating when to recruit vs. automate, including IR35 considerations for contractors
6. **Cash Flow Management**: 12-month cash flow projection showing investment phases and break-even points
7. **Risk Mitigation**: Address common UK-specific risks (client money handling, GDPR, Professional Indemnity insurance requirements during scaling)

**OUTPUT FORMAT:**
