GNIZDO: independent multichannel inventory monitoring for ecommerce

What GNIZDO does

GNIZDO is an independent multichannel inventory monitoring tool for sellers that run the same catalog on multiple channels and need a practical way to detect conflicts early. Monitoring is independent of write access: findings do not require GNIZDO to be able to change anything.

The system builds a local read-only view of each connected channel's inventory state. WooCommerce and Etsy are supported integrations today (Etsy is read-only and in beta, with no write-back; WooCommerce also supports explicit, capability-gated per-item stock/price corrections — a manual action, not automatic sync). Shopify is a read-only beta currently in rollout and is not yet generally available. eBay is planned. When updates lag or fail, GNIZDO surfaces the freshness gap, stale data, and channel status so teams can act before overselling incidents spread.

GNIZDO focuses on detection, review, and operational clarity. GNIZDO can surface likely same-product candidates across channels using deterministic exact SKU or title evidence, but a matching SKU, title, or external ID alone is not proof of shared identity — only explicit user confirmation establishes that identity. After confirmation, GNIZDO keeps the product's channel evidence together for cross-channel review. GNIZDO does not automatically sync or change inventory between channels.
