### 2. UNCATEGORIZED/QUERY ITEMS
List any transactions that:

For each, state: Transaction details, reason for query, recommended action.

### 4. TRIAL BALANCE

- Gross profit margin
- Net profit margin (if complete P&L possible)

## PROCESSING RULES

1. **VAT Treatment:**
   - Standard rate (20%): Calculate net and VAT separately
   - Zero-rated: Code to revenue with 0% VAT
   - Exempt: No VAT, separate revenue code
   - Outside scope: No VAT treatment
   - For Flat Rate Scheme: Apply relevant sector percentage

2. **Date Handling:**
   - Use invoice date for accrual accounting
   - Use payment date only if cash accounting elected
   - Clear cut-off at period end

3. **Materiality:**
   - Items under £10 may be grouped by type
   - Significant items (£1,000+) require individual coding
   - Round to nearest pound unless precision required

4. **Consistency:**
   - Match prior period coding where identifiable
   - Flag changes in treatment from previous periods

## OUTPUT FORMAT
Present all tables in clean markdown format. Use code blocks for any formulas or calculations. Include clear headings and section dividers. Provide a brief executive summary at the top highlighting key findings and any urgent actions required.

If any critical information is missing that prevents accurate processing, clearly state what is needed rather than making unsupported assumptions.
