Duplicate SKU Sync | POS Sync App Reviews


Duplicate SKU Sync | POS Sync App Description & Overview

Duplicate SKU Sync App helps to keep the inventories of products and variants having the same SKU in sync.

Why have duplicate SKUs?
  1. Selling Common Items: For example, you might sell unisex flip flops and have them listed on Shopify as both a men's size 8 and a women's size 10.

  2. SEO: You can create multiple listings for the same item but under different titles, descriptions, and meta keywords for improving SEO.

  3. Marketing: Duplicate listings with different keywords can be used as landing pages to target different audiences.

  4. Bundling: If you're selling 1. camera and 2. bundle of the camera with an online photography course then you can easily keep the inventory in sync by giving the standalone camera and bundle both the same SKU.

  5. Multichannel Selling: If you have listed an item on Shopify online store as well as POS (Point of Sale) and want to have different pricing. You can duplicate the item, assign the same SKUs but different prices, and then list one on the online store and the other on POS.

In all such cases, you will want to keep stock synced for all duplicated items since they are actually the same physical item.

Duplicate SKU Sync App

The app reads the orders on your Shopify store. If it finds an order item having a duplicate SKU, then all the duplicate items will be updated with the same inventory. All this happens in less than a minute, so it's near real-time. This ensures that the duplicate SKU inventories are in sync and you don't have to manually update the inventory each time you sell one.

Ease to Use

You simply have to install the app and activate sync with a click of a button. No manual installation or complicated setup.

Build for Scale

The app can handle thousands of duplicate SKUs and any number of orders without a worry.

Sync History

Each duplicate SKU inventory update is logged and can be viewed in the app dashboard

Restock Inventory

You can restock and update the inventory of all the same SKUs together with a single click via the app dashboard.

Multi-location Sync

If your items are distributed across multiple locations - no problem. The app will match stock levels for duplicate SKUs at each location.

Duplicate SKU Sync | POS Sync Comments & User Reviews 2024

(United States)

It does exactly what it says: it syncs inventory levels between product listings based on SKU. We are a brick & mortar first store and we have agreements with some of our suppliers to maintain different pricing online vs. in-store. To do this, we create one listing for the Online Shop channel and another for the POS channel with the same SKU. When an item is sold in person, Duplicate SKU Sync works its magic and updates the quantity of the other listing. We don't have multiple different products using the same SKU (our in-person and online listings have a 1-to-1 SKU match) and we give each variant of the product a different SKU, so we haven't run into any of the issues that other users are having.

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.

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


The app works great and it's saving our lives. It has some little improvements to be done, but the developers are very fast on replies and they want to improve the app by our needs, which I'm sure will be others needs as well. So far I'm very satisfied choosing Duplicate SKU.

Brilliant app, we use it to make sure that embossed options and duplicate products (so that we can show different colours on the front end of the shop) keep up to date. We had a small issue with POS orders not syncing stock and they sorted it instantly! Thanks


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!


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

I had been looking for an affordable option to do this. I was doing it manually but made a lot of mistakes, and it was taking so much time. I just try this app and I am so happy with how easy and fast it is. I will have to update most of my inventory to fix my previous mistakes but is a relief of how simple it is now. Thank you!


It's a good app, some occasional loading issues, would be great if it could store the SKU's so i don't have to type them in everytime when i need to update. Otherwise for where my business is at the moment, it suits my needs.


We love using this app, it has made our life easier. Our store has multiple variants sharing the same SKUs. This is because those variants are the same physical item. Each time there is an order we had to manually look for all the same SKU variants and update quantity. This app works like magic syncing the same variants and we dont have to lift a finger. Its awesome.


I should have taken those reviews seriously, I usually like giving businesses a chance, but this app is doing exactly the opposite of what it is supposed to be doing. I am amazed, because its called Same SKU Sync, which means if 1 product has 3 same skue it will sync them together, this isnt doing this at all and when support responded to my issues they said "its because 3 products have the SAME SKU, this is why it will not SYNC" LMAO? are you seriously just taking our information to sell it abroad? I mean if your app says something and does the opposite, so what is your motive? Will be reporting this app to shopify to take action.

Could have been a fantastic app, but the quantities are only adjusted when you sell an item. I needed all SKUs to be updated when 1 SKU's level changes (if it is sold or not) When will the next update be, that will fix this issue ?


Its the perfect little app that we wanted. Updating multiple items sharing the same SKUs was a pain. We tested on a few orders and it worked exactly the way we wanted. The pricing is also good. 5 starts!!!

The app does exactly what its named after. Its a lifesaver if you have same SKU variants and want to keep the stock in sync. Its simple, no-fuss and automatic. Have been using it for a few days now - its well worth the money.

(United States)

The app is having issues. The sync does not work. I have made multiple purchases to test the feature and it does not adjust/sync the quantity correctly.
