A merchant wants customers to be able to order gift vouchers via their site.

To ensure that gift vouchers are always available for sale regardless of actual inventory, a developer should utilize the "perpetual" flag in the product inventory record. By checking the perpetual flag in Business Manager, the inventory system treats this product as always available, effectively ignoring any inventory checks. This is particularly suitable for non-physical or digital items like gift vouchers, where the concept of physical stock does not apply. The perpetual flag setting ensures that the item can be sold without limits, which aligns with the nature of digital vouchers.
