SKU mismatches are one of the most common operational bottlenecks as order volumes grow.

Marketplaces use their own identifiers — “Listing IDs,” “ASINs,” and “FSNs” — while your internal system uses SKU codes.
When these aren’t mapped correctly, or when one SKU is used for multiple marketplace listings, errors appear such as:

• “SKU does not exist”
• “Item not found”
• “Mapping missing”
• “Order cannot be pulled due to missing SKU”

This challenge is amplified for products with variants (size, color), where each variant has its own listing on every marketplace.
