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!

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.

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!

This app was not very useful to me. I sell handmade notebooks. I have several different cover designs, each of which can be made with 6 different page options inside. I have virtually unlimited supply of pages, but only limited number of each cover. So if I have 5 covers left, I need to be able to link my page variants so that all 6 options are still available to customer, but no matter which combination of page options they choose, they can only purchase a total of 5 books in that design.
This app does sync inventory across variants, but if I set my stock level at 1, it will assign a value of 1 to each variant. If a customer orders just one of the variants, the app changes all the variant stock levels to 0 after the order is processed. So it appears to work. HOWEVER, it only syncs the inventory after an order is processed. It does not prevent a customer ordering two different variants in the same order. Because according to my store, I have 1 of each variant available. Even though I only have one cover left, a customer is still able to purchase two different books with that cover, meaning I can't fill part of their order.
Harold tried to explain to me that syncing the inventory in the cart, rather than after order checkout would slow things down and result in fewer sales. But the way this app currently works, it means I have to make some product variants unavailable when my inventory quantity gets to low numbers, meaning fewer choices for my customers and that results in fewer sales for me.
This app might be sufficient for some businesses, but I need a way to completely manage inventory at the product level, not the variant level, and this app just doesn't do that 100%. I'm yet to find an app that actually does.

Thanks for your review. The app syncs inventory changes for items sharing the same SKU (or barcode), it syncs changes after each order and cancel.

You had the app installed for a couple of minutes and there where no orders or cancels placed during the time you had the app installed.

Please let me know if you want to test the app again.

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.

Hi Ooh La Lou,

Very sorry to hear that you where having issues with the app.

I checked the logs and found what was happening, I sent you an email with information why the items where out of sync and how to solve this, would you be so kind to reply to that email.

Cheers,

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 www.puretranquility.com.au. Thanks so much Simple Sync.

Two stars for Harold actually responding to emails. Other than that, SimpleSync did not work. We have a very basic setup - 2 SKUs, 3 variants each, no custom code apart from a warehouse that sends Shopify the physical count of each SKU once an hour. SimpleSync failed to work for us - it decremented only the variant sold, and a few minutes later, the inventory went right back *up*. Harold is adamant that his app works, and the fault is in the way our site is setup. I installed Connected Inventory by InsCoder and it worked right out the box. So there's an obvious difference between how the apps are built - one works, the other doesn't.

Isn't able to load my inventory, probably not powerful enough to handle inventory over 2000.

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!

It works like a charm. It fully resolves the issue of not being able to link variant skus across many/all products.
