- ❌ Invoices with payments

- ❌ Tax-reported transactions

### **Better Alternatives:**
- Use **Return** instead for completed sales
- Use **Cancel** for quotations
- Use **Draft** status for incomplete invoices

   - Export data if required for records

2. **During Delete:**
   - Read confirmation dialog carefully
   - Verify invoice ID matches
