At a glance
Active AliExpress Listings for OOS SKUs on BC counts SKUs that are out of stock in BigCommerce but still active and buyable on AliExpress. BigCommerce is the source of truth for stock, so a SKU sold out on BC has nothing to fulfil, yet the AliExpress listing keeps taking orders. On a cross-border marketplace this is the most dispute-prone kind of oversell: AliExpress buyers already accept long shipping lead times, so they will wait, but they will not tolerate a cancellation after waiting. Every listing in this count is a cancellation and a dispute waiting to happen, which damages seller ratings on top of the lost order. The alert fires the moment the count rises above zero, because even one of these is a live liability.
Calculation
Vortex IQ cross-references each active, buyable AliExpress listing against the stock level of its BigCommerce source SKU and counts those where BC shows zero available stock. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.Worked example
A representative reading of Active AliExpress Listings for OOS SKUs on BC for a typical BC-to-AliExpress cross-border seller. On 17 Mar 26 the card reads 4, above the zero-tolerance threshold. A best-selling SKU sold out on BC overnight, but its stock update had not synced, so the AliExpress listing kept selling and took 3 orders it cannot fulfil. The operations team pauses the 4 listings at once, then decides whether to refund and apologise or to source replacement stock before the cross-border clock runs out.

Reconciling against AliExpress Seller Center
Where to look in AliExpress Seller Center: In Product Management the affected SKUs will still show as active with stock available, because Seller Center only knows the AliExpress side. The out-of-stock truth lives in BigCommerce, and the stock sync usually runs through the Feedonomics feed layer, so confirm the BC stock level and the last successful sync rather than trusting Seller Center alone. Why the Vortex IQ value may legitimately differ:
Cross-connector reconciliation: reconcile the AliExpress listing state, the BigCommerce stock level, and the last Feedonomics sync to confirm a true oversell rather than a sync gap. For divergence investigations, use Vortex Mind.
