What the audit checks

Missing SKUs

Variants without SKU values are flagged so fulfillment, reporting, CSV updates, and inventory work have stable identifiers.

Duplicate SKUs

Repeated SKU values are surfaced before they collide during bulk edits, warehouse handoff, or product-feed cleanup.

Missing barcodes

Barcode and GTIN gaps are called out for stores where channel feeds, retail workflows, or marketplace uploads expect identifiers.

When this page is the right fit

You are preparing a product feed, marketplace upload, or inventory sync and need to know which variants lack reliable identifiers.
You are about to bulk edit products and want to catch duplicate SKUs before CSV changes overwrite the wrong row.
An agency, VA, or operations teammate needs a fix-ready CSV instead of screenshots or scattered notes.

What happens after install

Install from the Shopify App Store with Shopify OAuth.
Open the embedded app and click Run audit.
Review high-severity SKU findings first, then barcode advisories.
Click Export CSV when the cleanup work needs to become an assignable task list.

No external Loftvex login is required. The app uses Shopify-managed install and billing flows. Its core catalog scan is read-only, while supported product fixes use a separate preview-and-confirm step.
