# Omnichannel Inventory Basics

To help you plan your implementation, familiarize yourself with Omnichannel Inventory concepts.

- **[How Omnichannel Inventory Works](https://help.salesforce.com/s/articleView?id=commerce.oci_impl_how_oci_works_b2b_d2c.htm&release=264.0.0&type=5)**  
    Review the typical flow when using Omnichannel Inventory with Salesforce Order Management and B2B Commerce and D2C Commerce.
- **[Fulfillment Locations in Omnichannel Inventory](https://help.salesforce.com/s/articleView?id=commerce.oci_impl_inventory_fulfillment_locations_b2b_d2c.htm&release=264.0.0&type=5)**  
    Omnichannel Inventory uses three objects to represent the facilities that fulfill orders: Location, Location Group, and Location Group Assignment. The complete set of locations, groups, and assignments is called a location graph. When using D2C Commerce, your location graph is limited to one location and one location group.
- **[Omnichannel Inventory Reservations](https://help.salesforce.com/s/articleView?id=commerce.oci_impl_inventory_reservations_b2b_d2c.htm&release=264.0.0&type=5)**  
    When a customer places an order, the system reserves inventory to fulfill the order and a reservation is created. When a reservation is assigned to a location group, you can implement business rules to transfer it to a specific location for fulfillment.
- **[Configuring Locations for Order Shipping](https://help.salesforce.com/s/articleView?id=commerce.oci_impl_config_locations_order_shipping_b2b_d2c.htm&release=264.0.0&type=5)**  
    You can configure a fulfillment location to ship ordered products.
