Inventory Mismatch Across Channels

What this looks like

• The same SKU shows different available quantities in different channels or systems.
• Teams spend time comparing exports or dashboards before they can trust the number they see.
• A stock adjustment in one system does not reliably propagate to every selling channel.

What to inspect

• The source-of-truth inventory quantity and the quantity currently exposed by each connected channel.
• SKU or variant mapping differences that make apparently identical inventory records refer to different items.
• Recent inventory writes, failed syncs and channel-specific availability rules before correcting quantities.

Operating response

1. Resolve product and variant identity before comparing quantities.
2. Read inventory from each relevant channel and calculate the mismatch explicitly.
3. Choose the system of record and the allowed direction of synchronization.
4. Use guarded writes and readback verification for supported inventory updates rather than blind overwrites.
