Inventory management for developers

Use or extend the HCL Commerce+ Inventory to manage your inventory and your Inventory Locations (ILs), where your inventory is stored and is delivered or shipped from. Inventory includes anything that can be physically accounted for in an Inventory Location, such as items, products, SKUs, bundles, and pre-built kits.

Inventory overview

The Inventory must be considered when implementing your Commerce+ storefronts in conjunction with physical stores or Inventory Locations, unless it is intended to be used as a simple and self-contained solution for inventory management.

In more complex business cases, the Inventory must be integrated within a custom inventory system. In such a system, the Inventory is used as the system of record for Commerce+ storefronts.

You can modify and extend the Commerce+ Inventory, to respond to your unique business requirements.

Automated file uploads

If your organization requires a more responsive inventory management solution, or a tighter integration with an existing inventory management system, you can implement automated file uploads via REST API.

This method can ensure that your Inventory contains more up-to-date inventory data without the need for manual updates or intervention.

For more information, see Automating an inventory data feed.

Subscribing to inventory and fulfillment-related events

If your organization requires a more responsive inventory management solution, or a tighter integration with an existing inventory management system, you can use the Inventory webhook to subscribe to inventory and fulfillment-related events.
