## Section 2: Change Details

**Description of the requested change:**
Rename the storage-location term "Rack" to "Bin" throughout the application: UI labels and JavaScript (`custom.js`), the barcode/label engine (`BarcodeManager.php`, `location_barcode_label.php`, `retrieve_rack.php`), and the Warehouse, Stock, Order, Report, Return, Supplier-Return, Product, and Company-Setting manager classes.

**Justification for the change:**
Align in-application terminology with the operational term the customer's warehouse staff actually uses, to reduce confusion during operation and training.

## Section 3: Impact Analysis

| Item | Detail |

| Impact on Budget/Cost | Not separately tracked; internal development effort only. |
