Nosto supports supplier costs and inventory level. The supplier-cost and inventory-level metadata can be used for creating advanced recommendation rules to promote products with a high margin or low-stock products.
The supplier-cost and inventory-level of a product are considered sensitive information and therefore does not exist in the page tagging, and instead, are sent over a secure API.
The extension relies on observers to detect changes to the catalog and synchronize it with Nosto. If you are synchronizing products from your ERP/PIM system, observers may not be triggered, and therefore it is necessary that you run a cron to bulk update products to Nosto.

The inventory-level metadata collection is disabled by default. You can toggle the inventory-level metadata collection by navigating to the configuration page and toggling Send inventory level to Nosto under the Advanced settings section.
Inventory-Level Metadata Settings Enabling / Disabling Inventory-Level Sync After Purchase
In some cases, syncing the inventory level after a purchase might add some loading time to the thank you page. As of version 3.7.8, you can disable it and leave this operation for a later time when running the indexer or updating the product manually.
