# What should I do if I need to update SKUs from multiple feeds in Stock Sync?

If you receive inventory for the same products from different suppliers or warehouse locations, you should create separate feeds in Stock Sync. Assign each feed to update only the specific Shopify inventory location it belongs to.

This setup ensures that updates from one supplier do not overwrite stock from another. If you need missing SKUs from a particular feed to be set to zero, enable the Out of Stock Strategy in that specific feed—Stock Sync will only reset quantities for the location that feed is mapped to, leaving other locations untouched.
