GNIZDO — drift monitoring for multichannel sellers

Quiet monitoring that spots stock + price drift early.
You review a short daily list and decide what to fix.

  • Detect inventory and price drift across WooCommerce, Etsy, eBay, and Shopify.
  • Review a short daily list with the exact SKU, what drifted, where, and why it matters.
  • Catch mismatches before they become cancellations, refunds, support tickets, or marketplace penalties.

Over time, WooCommerce, Etsy, eBay, and Shopify drift out of sync. This is the moment GNIZDO starts watching.

Small batches start in March 2026.

GNIZDO doesn’t replace your workflow. It watches for drift and flags only risky mismatches. You review exceptions — not the whole catalog.
No forced automation. No workflow disruption.
The quiet problem

Your inventory quietly drifts away from reality.

Over time, multichannel inventory starts to drift. One channel updates first. Another lags. Someone patches a spreadsheet. Everything looks “fine” — until you’re cancelling orders, resyncing catalogs, and explaining refunds.

Three-step flow

How GNIZDO works

A quiet monitoring loop that stays out of the way until something drifts — then it shows you what changed, where, and what could break next.

    Continuous sync checks

    GNIZDO watches inventory, prices, and orders quietly in the background — and flags drift before it becomes cancellations, refunds, and time-consuming cross-checks.

Before damage

Out of sync detected before damage

A short review list keeps from turning into refunds, cancellations, and penalties.

Price drift between channels (site vs feed).

“Price shown in Merchant Center is different from the one shown in website.”

Orders exceed stock (two channels accept the last unit).

“2 different customers at the same time, the stock was just 1 that time”

Stock drift that stays invisible until it breaks.

“Some products that are out of stock in Woocommerce appear as in stock on Facebook.”

Review list with three alerts

“I'm getting tired of cancelling orders and getting bad reviews because Amazon decided to sell 12 units when there's only 10 available for example!”

FAQ

Why drift causes oversells, mismatches, and pricing mistakes

Quick answers (no solutions) to the most common “why is this happening?” moments in multichannel selling.

Why did I oversell if inventory showed stock available?
Because platforms don’t share a single source of truth. Orders can be accepted in parallel, API updates can fail, and stock numbers drift between systems. What looks “in stock” in one place may already be sold elsewhere.
Why do stock numbers differ between channels?
Each platform updates inventory separately. Sync tools often rely on push events. When an update fails or is delayed, numbers stop matching — and the mismatch usually stays invisible until something breaks.
Why does “real-time sync” still lead to errors?
Real-time sync reduces delay but doesn’t prevent failure. Network timeouts, API limits, or hidden platform logic can block updates without clear alerts. Drift accumulates silently.
Can two customers buy the last unit at the same time?
Yes. When orders are placed close together on different channels, both may be accepted before stock updates propagate. Most systems aren’t designed to handle cross-channel concurrency reliably.
Why do prices show differently across platforms?
Channel rules, currency rounding, promotions, or sync delays can cause price drift. Without regular checks, you may sell below intended margin without noticing.
Why do we keep needing to “resync everything”?
Full resyncs are often used as a workaround when systems lose alignment. If resync is a routine task, it means drift is happening continuously in the background.
Why do spreadsheets stop working as we grow?
Manual tracking doesn’t scale with SKU count, sales velocity, or number of channels. The more moving parts you add, the faster data goes out of date.
