# Supplier Cost & Inventory Level

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.
