Catch inventory mismatches before they become refunds

GNIZDO is an independent multichannel inventory monitoring tool for ecommerce sellers. It observes your store catalog read-only — WooCommerce and Etsy today — and shows channel freshness, stale inventory data, and overselling risk before a sync gap turns into refunds or bad reviews.

  • Spot stale inventory data
  • Watch channel freshness
  • Track stock and price changes
  • Review oversell-risk evidence

Platforms

WooCommerce and Etsy are supported today with read-only catalog observation (Etsy is in beta). Shopify and eBay sellers face the same sync and mismatch problems — those channels are a future direction, not live integrations yet.

One SKU, four sources, three conflicting answers — the mismatch that drives oversells and price drift. GNIZDO today observes each connected store read-only as its own channel (WooCommerce and Etsy); matching one SKU across platforms is a future direction and requires explicit or confirmed shared item identity.

THE QUIET PROBLEM

A single lagging inventory update can open a costly sales window.

One channel updates first. Another lags. A spreadsheet gets patched manually. Now the same SKU shows different stock or price in different places. Most sellers find it after the order comes in, not before.

It usually surfaces as one of two symptoms: overselling — unavailable items keep getting ordered — or inventory not syncing — channel data goes stale and stops matching the store.

Detection

What GNIZDO shows

A faster way to see when channel data can no longer be trusted. GNIZDO keeps a read-only view of each connected channel — catalog state, freshness, recent changes, and import health — so stale inventory data and overselling risk are visible before the next order.

Channel-local catalog state

See the latest known stock, price, and listing state for every SKU in a connected channel.

Freshness and trust signals

See when each channel was last successfully observed and whether its data is still fresh.

Change evidence

Review what changed between observations — stock drops, price changes, listing state — before acting.

How it works

What you get from GNIZDO

GNIZDO is detection-first, not sync-first. It does not automatically sync or write to your store — it observes channel state independently and surfaces the exceptions that need attention.

  • Connect your store

    Connect a WooCommerce or Etsy store as a channel. GNIZDO imports the catalog read-only and never changes it automatically. WooCommerce supports explicit, capability-gated per-item stock or price corrections when you choose to make them; Etsy connections stay read-only, with no write-back.

  • Build channel state

    GNIZDO keeps a local read model of each channel's catalog so freshness and changes can be tracked over time.

  • Review detected signals

    See stale channel data, incomplete imports, stock and price changes, and overselling-risk signals — with the evidence behind each one.

The hidden cost of overselling

Overselling is usually the visible symptom. Refunds, support load, manual cleanup, and lost repeat purchases stack up quietly.

FAQ

Questions before you create an account?

What kind of issues does GNIZDO catch?
Stale channel data, incomplete or failed imports, unexpected stock and price changes, listings still active at zero stock, and overselling-risk signals.
Does GNIZDO change inventory automatically?
No. GNIZDO does not automatically change inventory — it shows evidence so you decide what to do. WooCommerce supports explicit, capability-gated per-item stock or price corrections when you choose to make them; Etsy connections stay read-only. There is no automatic cross-channel sync or write-back.
Does GNIZDO prevent overselling?
No tool can guarantee that — channels accept orders independently. GNIZDO shortens the time a stale or risky channel state goes unnoticed, which shrinks the window where oversells happen.
Which platforms are supported?
WooCommerce and Etsy are supported integrations today (Etsy is read-only and in beta). Shopify and eBay sellers face the same problems, and support for those channels is a future direction — not a live integration yet.
What data does GNIZDO read?
SKU, stock, price, listing status, channel state, and freshness signals needed to detect mismatches.
Where is data stored?
GNIZDO stores a local read model of connected channel observations so it can compare state and show evidence.
How does GNIZDO handle privacy and security?
GNIZDO does not ask for platform passwords on the landing page and keeps data use focused on detection-first inventory review. See the privacy and security pages for details.
How is this different from sync tools?
Sync tools push stock updates between channels. GNIZDO does not sync or write anything — it focuses on detection: freshness, changes, and risky exceptions before they become customer-facing problems.
