Rules home with SKU health, and a rule's Confirm card over it

Fix missing, duplicate and messy SKUs, and undo any run. New products get SKUs automatically.

For stores whose SKUs have drifted: variants with none, two variants sharing one, or SKUs written three ways. A rule picks products by vendor, type, tag, collection, option, price or status, and its format builds each SKU from text, counters and conditional parts, written to the barcode too if you choose. SKU health shows what's missing, duplicated or out of format, and any run can be undone. Set a rule to Automatic and new products that match it get SKUs on their own.

Rules give each vendor, product type, collection or tag its own SKU format
Preview every SKU on your own products before anything is written to Shopify
SKU health finds variants missing a SKU, duplicate SKUs and SKUs out of format
Automatic writes SKUs for new products that match a rule, while you're away
Resolve duplicates in one run, and undo any run for days afterwards

I really dig this tool! It helped me finally get my SKUs under control. Easy to use...I like the visual interface to build the format. The developer was very quick to respond when I had an issue, and sent me a video showing me what I needed to do!

This app is terrible. It does not automate correctly and often creates duplicates. There are much better apps out there.

Updated 17 October 2026: the app has been rebuilt since this review, and the rest of this reply says what changed.

Thanks for the honest review, and sorry the app let you down. I couldn't reproduce it at the time, and that isn't the same as it not happening.

Since then SKU Manager has been rebuilt as 3.0. Duplicates has its own page that finds every SKU held by more than one variant and resolves them in one run. Automatic writes SKUs for new products on its own, and Activity shows what it wrote and what is waiting. Every run can be undone.

You'd be welcome back to try it. If anything doesn't behave, email me at taj@fontainesoftware.com and I'll look at your store myself.
