Platform Integrations for Detection-First Inventory Visibility

GNIZDO is an inventory truth layer for connected sales channels. It builds a local view of catalog state so teams can review mismatch, delay, price drift, freshness gaps, and overselling risk across WooCommerce, Etsy, eBay, and Shopify.

Closed beta. Rolling invites for selected stores. Platform support is rolling out gradually.

How GNIZDO Detection-First Integrations Work

Most multichannel inventory tools attempt real-time synchronization—pushing stock updates from one platform to all others whenever something changes. This approach breaks silently when API calls fail, networks timeout, or rate limits kick in.

GNIZDO takes a detection-first approach. We assume drift will happen and focus on catching it early:

  • Local catalog snapshot — We build a working view of connected channel state so operators can compare stock, price, and listing data in one place
  • Mismatch and delay visibility — We surface where channels stop matching and where freshness or status signals show stale state
  • Overselling risk review — We make low-stock conflicts visible earlier so teams can inspect the affected SKU and channel before damage spreads

Instead of promising perfect updates, we make drift visible so you can address it before customers are affected.

Detection depth and timing vary by platform based on API capabilities and rate limits.

WooCommerce Integration

Planned scope: Local catalog snapshot, stock mismatch review, and price drift visibility

WooCommerce integration focuses on sellers using WordPress as their primary ecommerce platform while also selling on marketplaces. Common scenarios include:

  • Running a branded WooCommerce store alongside Etsy and eBay listings for the same products
  • Managing wholesale pricing in WooCommerce while maintaining different retail pricing on marketplace channels
  • Using WooCommerce as inventory master with stock flowing to other platforms

WooCommerce Stock Mismatch Detection

The WooCommerce path starts with current catalog state from the connected channel. That local snapshot makes it easier to compare WooCommerce stock against connected marketplace listings for the same SKU and review where quantities drift.

This catches common problems like:

  • Sales on one channel that didn't update WooCommerce inventory
  • Manual WooCommerce adjustments that didn't propagate to marketplace listings
  • Returns processed in WooCommerce that left marketplace inventory unchanged

WooCommerce Price Monitoring

Price monitoring tracks whether your WooCommerce product pricing matches what you're charging on other channels. This is especially relevant for sellers who:

  • Run promotions on their WooCommerce store but need marketplace prices to stay consistent
  • Use tiered pricing strategies where WooCommerce wholesale prices differ from marketplace retail
  • Change prices frequently and need to ensure all channels reflect current strategy

WooCommerce Operational Review

When operators investigate a conflict, WooCommerce state still needs to be compared against the latest known channel state elsewhere. The goal is earlier visibility into which SKU drifted, which channel stayed stale, and what needs manual review first.

Etsy Integration

Planned scope: Stock mismatch visibility, price drift visibility, and overselling risk review

Etsy integration targets handmade and vintage sellers managing inventory across Etsy plus their own website or other marketplaces. Key focus areas:

Etsy Inventory Monitoring

Etsy's API allows us to pull current stock levels for your active listings. We compare these against your actual warehouse inventory and other channel listings to detect:

  • Etsy listings showing availability for products that sold out on other channels
  • Stock quantities in Etsy that don't match your central inventory counts
  • Etsy draft listings or renewed listings with outdated stock numbers

Etsy Stock Mismatch Detection

Because Etsy does not automatically update when you sell on Shopify or WooCommerce, stock mismatches are common. A local snapshot and latest-known-state view make those gaps easier to review:

  • Item sells on Shopify → Etsy still shows old quantity → mismatch becomes visible in review
  • You manually adjust inventory → forget to update Etsy → drift detected based on polling schedule
  • Return processed elsewhere → Etsy doesn't reflect returned stock → stale-channel mismatch remains visible

Prevent Overselling on Etsy

Etsy oversells damage your shop metrics and search ranking. Detection-first visibility helps reduce oversell risk by:

  • Comparing Etsy committed orders against actual available inventory
  • Identifying when Etsy inventory + other channel orders exceed physical stock
  • Keeping the conflict visible with channel context before fulfillment decisions are made

Etsy Operational Review

When Etsy conflicts happen, teams still need one place to compare the latest known stock state, freshness, and channel status before deciding what to correct on the affected listing.

eBay Integration

Planned scope: Stock monitoring, price tracking, active listing monitoring

eBay integration serves sellers managing fixed-price listings across eBay and other platforms. Focus areas include:

eBay Inventory Monitoring

eBay's inventory system operates independently from other platforms. We monitor:

  • Stock quantities in active eBay listings versus actual available inventory
  • eBay listing revisions that change quantities without updating other channels
  • Out-of-stock eBay listings that should be available based on other channel data

eBay Stock Mismatch Prevention

eBay penalizes sellers for transaction defects, including cancelled orders due to out-of-stock situations. We help prevent these by:

  • Detecting when eBay shows higher stock than you actually have available
  • Flagging mismatches between eBay quantities and your other platform listings
  • Monitoring inventory drift during polling intervals

eBay Conflict Visibility

eBay conflict review is about seeing how the latest known eBay state compares with other channels when the same SKU is under pressure:

  • When eBay and Shopify orders both claim your last unit
  • When total orders across channels exceed stock before any platform updates
  • When eBay Best Offer acceptances create unexpected inventory commitments

Shopify Integration

Planned scope: Local snapshot visibility, price consistency review, and mismatch investigation

Shopify integration focuses on sellers using Shopify as their primary platform while also maintaining marketplace presence. Common scenarios:

Shopify Multichannel Inventory

Shopify's built-in inventory management does not automatically match external marketplaces. We help you detect and review those gaps by:

  • Monitoring Shopify inventory levels against Etsy, eBay, and WooCommerce listings
  • Detecting when Shopify stock changes don't propagate to connected channels
  • Flagging inventory discrepancies across Shopify locations and marketplace listings

Shopify Stock Mismatch Monitoring

We compare Shopify inventory against connected channels and make review context visible when:

  • Shopify shows different quantities than your marketplace listings for the same SKU
  • Inventory adjustments in Shopify admin don't reflect in marketplace stock
  • Shopify variant inventory drifts from bundled product availability elsewhere

Shopify Conflict Review

When Shopify and marketplace state diverge, operators need a clearer review surface for situations like:

  • Situations where Shopify and marketplace orders together exceed available stock
  • Timing conflicts where orders arrive faster than inventory updates propagate
  • Multi-location Shopify fulfillment that affects marketplace availability

Multichannel Integration Architecture

Our integration approach prioritizes reliability over speed:

API Connection Management

We maintain authenticated connections to each platform's API and handle:

  • Authentication refresh and token management
  • Rate limit compliance to avoid API restrictions
  • Retry logic for failed requests
  • Graceful degradation when platforms experience downtime

Data Monitoring Cadence

A first snapshot builds local visibility, and ongoing checks refresh the latest known state as platform constraints allow:

  • Connected channels refresh into a local working view
  • Fast-moving inventory benefits from more frequent review
  • Freshness always depends on platform limits and response timing

Actual update-delay timing depends on each platform's API rate limits and response times.

Mismatch Detection Logic

Our core detection engine:

  • Compares data across all connected platforms
  • Identifies discrepancies in stock, pricing, and order status
  • Preserves latest known stock, pricing, and listing state for review
  • Surfaces freshness gaps and channel status alongside the mismatch

What Integration Doesn't Include (Yet)

To set realistic expectations, our initial integrations do not include:

  • Automatic inventory updates across platforms (we detect, you decide what to update)
  • Product listing creation or bulk uploads
  • Automated repricing based on competitor analysis
  • Shipping label generation or fulfillment automation
  • Customer communication or review management

We're focused on inventory truth, daily visibility, and channel-scoped review first. Additional features come later based on seller needs.

Beta Access and Rollout Timeline

Closed beta — Rolling invites for WooCommerce + one marketplace platform

Next beta phases — Gradual expansion to additional platform combinations

Ongoing — Weekly beta cohorts as we validate stability and support capacity

We're deliberately limiting beta size to ensure:

  • Proper onboarding for each seller
  • Time to address integration issues before scaling
  • Feedback incorporation before general release

Getting Started
