Duplicate SKU Sync Master

We recently discovered that some items have not synced properly for over five months, preventing us from selling these products. After reporting the issue, we were offered only $24 as compensation, despite having paid $120 during this period. As a result, we will now explore alternative solutions.

i upgraded from the free plan and now i am having issues with inventory. products that have been out of stock for weeks magically have new inventory, resulting in oversold products. Its a pain, especially when dealing with TikTok Shop's cancellation policies

This app solved a very tricky problem for me—automatic synchronization of the same SKU is truly amazing.

5/2025 UPDATE: Original issue was fixed from 2021, but now I have a new issue where the app is removing x2 the amount of items being sold. Example, I stocked an item at 15 pcs. 4 were sold. It synced the skus to have only 7 left in stock. I have to keep babysitting my sales again. As the other review from March 2025 mentioned, there is a high chance inventory hasn't been syncing properly for months. I noticed one of my items went out of stock really quick and now i'm left with a lot of stock that could've been sold during the height of popularity of my item. What am I paying a plan for?

Their support team got back to me, basically said if an order contains 2 different items with the same sku, syncing will glitch. If your item sells fast and orders are made back to back, syncing will glitch. If your customers don't wait for the app to finish syncing inventory(may take seconds to minutes) then syncing will glitch. Basically the app has now become trash which is the complete opposite of my original experience using it back when I was make back to back sales without a problem. Unfortunately will have to be on the lookout for a new app.

I really needed an app that did exactly what this app offers, or at least described to offer. I make custom acrylics of different designs but essentially all using the same base material. I have multiple designs using the same sku. Before going live I tested the app and it seemed to work. Now that my shop has gone live the syncing won't work at all. I still have to manually edit the inventories now. I contacted support and I'm hoping to get a reply soon because I can't keep watch over my shop for hours. Once they get back to me I hope they can fix this or else I'm gonna need to find another solution.

Works great!

This has worked well for us in our case. We use this app to sync inventory between retail and wholesale products.

We had a feature request for the app to be able to export a CSV of all inventory to help us get an overview of our stock levels. The team got to work on it and added the feature for us with a quick turnaround. We're very thankful and glad to be working with Duplicate SKU.

It syncs my products with the same SKU perfectly. I also like how I can edit my stock mannually per SKU code in the app, and don't have to edit the stock on 3 different places on the website. If you're looking for an app that syncs the stock of products with the same SKU code, I would defenitely recommend this app!

Simple lifesaving app. Makes managing duplicated sku products much easier. The best things about this app is product synchronisation, so if inventory of duplicated sku product changes, the app on other products with the same sku make changes too!

Very pricy for the service. Not really satisfied. I will look for other solutions in the next future.
