Catch Shopify and eBay sync failures before they become oversells

SyncGuard compares active eBay inventory with Shopify and turns quantity, price, and missing-SKU differences into a focused, read-only findings queue.

Install and open SyncGuard from the Shopify App Store or Shopify Admin. Shopify starts the secure authorization flow automatically.

• Read-only by design. SyncGuard observes catalog state; it does not modify products, listings, inventory, or prices.
• Risk-first findings. Oversell risks, price drift, and orphaned marketplace SKUs are prioritized in Shopify App Home.
• Continuous coverage. Run a check on demand or let the durable worker schedule hourly reconciliation.
