Inventory Comparison — Amazon vs Walmart
Side-by-side quantities pulled directly from each platform's API. Click Refresh to fetch fresh data.
Note on data freshness: Amazon's report API can lag by 5–15 minutes vs. live Seller Central.
Walmart inventory updates in near-real-time. Mismatches under a few units may resolve on the next refresh.
The displayed quantities reflect what each platform's API returned at the timestamp above.
Master quantity push: Enter your true on-hand count in the green column and click Push
to set that quantity on both Amazon and Walmart at once. A confirmation shows exactly what will change before anything is written.
Walmart is verified by reading the value straight back; Amazon's API is asynchronous (it accepts the change and applies it within a few minutes, confirmed on the next refresh).
Every push is recorded in an audit log.
Note: Because a master push sets both platforms to the same number, the 15-min auto-syncer sees them already matched and leaves them alone — the two won't fight. Every push is logged with the prior quantities so any change can be traced or reversed.
