App working great so far. We sell uniforms for different schools that share the same SKU's. This allows us to keep our inventory accurate between different product variants. Harold is very responsive and helpful. Happy customer so far.

This app solves a fundamental issue for our store super elegantly and with hardly any oversight/setup. In addition, whenever I have run into a slight issue, Harold has been very quick to respond and help me get it resolved. Highly recommended!

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!

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.

Fantastic app! Does exactly what it says and exactly what we need. Even more importantly, A++ customer service. Responsive, dedicated and effective. Thanks!!

Amazing APP. Our parts are compatible for many different laptops so we really needed SimpleSync to allow us to create multiple products using the same SKU. SimpleSync updates the inventory for all identical SKUs when a product is sold, or returned. Highly recommend if you need to publish may product titles-descriptions that are the same SKU.

Exceptionally simple to use, minimal overhead / maintenance, and effective. We're using it for ticket variants (adult / child / senior) which have different prices but each take one seat. And also for dinner entree options - multiple menu choices but limited seating per date. We've looked at a bunch of apps and this does just what we need!
