Private by design: your CSV is parsed locally in the browser. We only record anonymous aggregate events and optional feedback.

Should this run continuously?
We are evaluating a Shopify app that would monitor shared inventory, detect drift automatically and surface reconciliation issues before they become overselling.
How it works
Scan locally
Your browser checks repeated SKU groups and compares quantities.
Review exceptions
We separate quantity drift from duplicate SKUs that may be intentional.
Common questions
Does it change my store?
No. This page has no Shopify access and cannot modify inventory.
Is every duplicate SKU an error?
No. We flag candidates and call out quantity disagreement as drift.
Where does my CSV go?
Nowhere. Parsing happens locally in your browser.
Is this inventory software?
No. It is a free diagnostic. Always review findings before acting.
