### ✅ 2. QuickBooks Integration Enhancement

**File:** `app/integrations/quickbooks.py`

**Improvements:**
- ✅ Enhanced account mapping with auto-save functionality

- ✅ Improved error handling with proper error messages
- ✅ Better configuration requirements

**Before:**
```python
if not account_id:
    account_id = "1"  # Hardcoded fallback
```

**After:**
```python
if not account_id:
    error_msg = f"No expense account found. Please configure account mapping..."
    raise ValueError(error_msg)
```

**Impact:** More reliable integration with better error messages.

- ✅ `DELETE /api/v1/inventory/items/<id>` - Deactivate stock item

#### Warehouses
- ✅ `POST /api/v1/inventory/warehouses` - Create warehouse
- ✅ `GET /api/v1/inventory/warehouses/<id>` - Get warehouse
- ✅ `PUT /api/v1/inventory/warehouses/<id>` - Update warehouse
- ✅ `DELETE /api/v1/inventory/warehouses/<id>` - Deactivate warehouse

#### Suppliers

```python
# Check for duplicate code
existing = Supplier.query.filter_by(code=code).first()
if existing:
    flash(_("Supplier with code '%(code)s' already exists", code=code), "error")
    return render_template("inventory/suppliers/form.html", supplier=None)
```

**Impact:** Data integrity improvement.
