Model 5 - Real-Time Inventory Availability at Add-to-Cart

Model 5 is appropriate when you want to minimize the risk of having a customer order a product that is not available. And have your Inventory Management System respond to real-time requests for product inventory status.

Model 5 requires customization.

Salesforce B2C Commerce calls the front-end system at add-to-cart for a real-time stock level check. The merchant keeps inventory data reasonably fresh, perhaps with a daily batch feed.

If the following conditions exist:

• There is an inventory list that is periodically refreshed.
• ProductInventoryList.DefaultInStock = true

The result is that all products appear to be in stock until the customer attempts to add-to-cart. At this point, the customer can be notified that a product is partially or totally unavailable. B2C Commerce doesn't notify a customer of an availability issue at checkout. The storefront behavior is as follows.
