Free CSV audit kit for multi-channel sellers — catch oversells, stale listings, and price gaps before they hurt you.

🔍 What the tool flags

CRITICAL Same SKU active on multiple channels with different quantities — oversell risk

HIGH SKU active on one channel but inactive/dead on another — stale listing

MEDIUM Same item priced 20%+ differently across channels — price gap
