What are the conditions for stock updates from a supplier feed?

Stock updates only occur when the SKU in your store matches a SKU in the supplier feed. If a product exists in your store but is not listed in the feed, its stock remains unchanged unless you enable the Out of Stock Strategy, which sets unmatched items to 0.

You can also set custom quantity rules based on values provided by your supplier, such as mapping Y to 1 and N to 0, or converting codes like IS, OOS, and NA to specific stock quantities. If your supplier only provides text values like "in stock" or "out of stock", you can set a rule using the Equal condition to assign a fixed quantity (for example: Equal → in stock → 5). Additionally, you may apply custom conditions such as converting any supplier stock of 5 units or fewer to 0. These rules must be configured inside the feed’s Quantity Field settings.
