AI summary
The app specializes in synchronizing inventory across product variants with shared SKUs, addressing Shopify’s limitation of tracking stock only at the variant level. It enables merchants to manage inventory at the product level, ensuring stock updates propagate automatically when variants are sold. Key strengths include straightforward setup, requiring only matching SKUs, and reliable performance for businesses with shared inventory needs, such as limited-edition prints, customizable products, or event tickets. The app also offers responsive customer support, often resolving issues promptly. However, limitations include occasional delays in inventory updates for stores with large SKU volumes and a lack of real-time cart synchronization, which can lead to overselling in certain scenarios. Some users report inconsistent functionality over time, requiring manual intervention. The app is particularly effective for small to medium-sized businesses but may struggle with high-volume inventories. Pricing transparency has been noted as a minor concern. Overall, it provides a practical solution for inventory synchronization but may not fully meet complex inventory management needs.

★★★★★DEMO - SOAfrom Canada · 11 March 2023
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.

- LDLycette Designs★★★★★
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!
- BDBulbs Direct★★★★★
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.
- JGJuniper Grove★★★★★
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.
