Catch purchase-order errors before fulfillment

POGuard matches incoming item codes to Shopify SKUs, checks case-pack quantities, and locks export until every blocked line is reviewed.

Install POGuard from the Shopify App Store, then open it from your Shopify admin. Manual shop-domain installation is not supported.

• Browser-only files. Purchase-order contents are not uploaded to the app server.
• Read-only catalog access. The app cannot create orders or change inventory.
• Human confirmation. Unknown codes and invalid pack quantities stay blocked until a person resolves them.
