This app!!! Solves the problem with Shopify not allowing merchants to set stock to the product level. Let me tell you how bummed out I was when I spent the last year working on migrating to Shopify from WooCommerce and not being able to set stock at the product level. Shopify only allows you to set stock to the variant level. As I only sell limited edition prints offered in multiple sizes. I couldn't make this work on Shopify. SimpleSync solves this problem. This is actually my demo store to test apps before trying them on my actual store as we are getting ready to launch and this is the final piece I needed to allow our business to work. I've spent all day testing different apps, making test orders and this app works works flawlessly and extremely fast (unlike the others I've tested). I'm beyond grateful when apps like this work so efficiently. Harold also provided the best customer support in answering my questions before I downloaded the app. It's so easy to setup, by simply using the same SKU you want synced. I highly recommend this app to anyone looking to solve the issue with Shopify not allowing merchants to set stock at the product level.

The app worked perfectly for 2 1/2 years for us. We no longer need the app to run a sync with shared products/virtual products, but I would highly recommend!

Used to sync the inventory quantity of my product variants. Easy to install, easy to understand and if you need help Harold is always an email away.

I needed this app to sync the inventory quantity of variants and this worked for us!

We sell customizable journals/notebooks. Each notebook cover is listed as a separate product in our shop with variants for the paper that goes inside them. We don’t need to control the inventory for the paper, but we did want to control the inventory for the covers. Shopify didn’t have this capability so we searched and found this app, SimpleSync, that would do it for us.

The app uses the SKU number (which can be any number you want) to control the inventory. It did take a few minutes to add the SKU number to all of our products. But that’s all we had to do.

The real story behind our experience is that at first, The app didn’t install properly due to a Shopify error. I contacted the app developer Harold and he worked tirelessly to resolve our issue and get the app set up. I’m talking emails in the middle of the night and constant communication until the issue was resolved.

5 stars for Harold and his support, as well as 5 stars for the app.

PERFECT! This app solved my problem with having different prices on POS and online for the same product. Well worth the money every month. Simple and automatic. Support is very fast too!

This app works perfectly for my small business. I sell custom made candles and needed to count the amount of stock (jars and containers) but not the individual scents I pour the candles in for my customers. I am not tech savvy at all but found it easy to set up, all I needed to do was set the same SKU for each container and its variants. I watched the first order come in since installing it and like magic the app has 'synced' the correct stock. You can see it in action at Thanks so much Simple Sync.

Harold is incredibly helpful and replied to all my emails quickly, helping me to set up the app to work in my shop. I was searching for months for a way to synchronise inventory for different variants of the same item and this app does exactly what I need. Highly recommended!

Love using simplesync - it's easy to install and start using, super straightforward, does exactly what it's named after. The one time I had an issue with it, Harold was quick to respond and fix the problem. Love the new update - being able to choose between viewing all your SKUs, or only duplicated ones is a great feature.

The app works. This app is a life saver if you have a lot of products sharing the same SKU. There will be issues with updating time if you have a lot of duplicate SKUs to update through this app. However, this is the only solution there is. Harold responds quite quickly to questions and issues.

Don't go anywhere else!! This app made my life SO much easier. I tried another app (Shopify assistant) and it was so complicated and literally made me cry. This was SO easy! It's working perfectly. THANK YOU!
