Write SKUs from formats you build, catch missing and duplicate SKUs, and undo any run.

Rules decide which products get which SKU format. A rule picks products by vendor, product type, tag, collection, title, option, price or status, and its format builds each SKU from text, counters and conditional parts. Preview every SKU before it's written. When Automatic is on, new products that match a rule get SKUs within 20 minutes of being added. SKU health shows which variants are missing a SKU, hold a duplicate SKU or are out of format, and any run can be undone.

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.

Hey Lori,

I’m sorry for the poor experience you had with the app. I reached out earlier to better understand the duplicate issue you mentioned, but I wasn’t able to reproduce it without more details from your store setup. I’d still be happy to help investigate and walk through the setup with you directly. If the issue was caused by the app, I’ll do everything I can to make it right.

Thanks,
Taj
