Duplicup ‑ Duplicate SKU Sync

Everything about this app is perfect for me. I had created duplicate listings for my 2 stores and had tags to identify where the products were. But with the last app I used this did not prevent overselling even though it was supposed to. The support I received from Aviad was beyond what I anticipated. He found a way to make this work! What a relief. We all know how awkward it is to oversell and disappoint our customers. Thank you Aviad and the Duplicup team!!!

The customer service was amazing in helping me get everything set up for my release and ensuring the app was working correctly. A must have for brand owners and sellers

We looked all over for a solution and finally found this. We had a specific issue that required some some custom coding to get it working. Aviad was always on top of it and went above and beyond to make sure Duplicup worked perfectly with our store. Highly, highly recommend.

I’ve tried several other apps for managing shared inventory across variants and locations, and none of them quite delivered. This one finally does. Everything stays perfectly in sync, which has saved us a huge amount of time and eliminated the constant headaches we used to deal with. What really sets it apart is the support. It’s incredibly fast, genuinely helpful, and the team goes above and beyond. Any time we’ve reached out, we’ve gotten clear, thoughtful responses almost right away. That level of care makes a massive difference. If you’re looking for a reliable solution that actually works, this is the one. Highly recommend.

We needed a slight tweak to an existing feature and we reached out and the devs had the feature added within a few days. No other SKU sync tool lets you manually link product skus. This is a game changer for our business and quite helpful. Thanks so much!
