## Menu Items Added

All new features are accessible from:
**Accounting → Reports → [Feature Name]**

- General Ledger
- Budget vs Actual

## Permissions

All new features use the existing `accounting.view_all` permission.

## Next Steps

To complete the implementation, you need to:

1. **Create Views** (Blade templates):
   - `Resources/views/budget-vs-actual/index.blade.php`
   - `Resources/views/general-ledger/index.blade.php`
   - `Resources/views/manual-journal-entry/index.blade.php`
   - `Resources/views/manual-journal-entry/create.blade.php`
   - `Resources/views/manual-journal-entry/show.blade.php`

2. **Run Migration**:
   ```bash
   php artisan migrate --path=Modules/AccountingReports/Database/Migrations
   ```

3. **Test Features**:
   - Test budget creation and budget vs actual report
   - Test general ledger for different accounts
   - Test manual journal entry creation
   - Verify automated payment and expense journal posting

## Integration Notes

- **Payment Journal**: Automatically posts when `TransactionPaymentAdded` event fires
- **Expense Journal**: Automatically posts when `ExpenseCreatedOrModified` event fires
- Both listeners are registered in `AccountingReportsServiceProvider`
- All features respect location permissions and business scoping
- All features include proper error handling and logging
