When a customer places an order in your Lightspeed eCom (E-Series) online store, it receives a unique numeric ID. This ID helps you and your customers to distinguish one order from another. The order ID is displayed in the order details, in your online store's order invoices, and email notifications.

You can customize order IDs used in eCom with a custom prefix and suffix to fit your business needs. For example, you can add the Online- prefix for your online sales.

Customized order IDs are used only in eCom, not in the Retail POS (X-Series).
