Description

SimpleSync keeps inventory in sync based on the SKU for two or more products.

SimpleSync is very useful if you're selling different products that are physically the same. SimpleSync keeps the inventory of these items in sync. SimpleSync also helps you sell more when you're selling a unisex product. You're going to sell more items if you focus your product pages on men and women separately. Make two products in the Shopify admin, give them the same SKU and you're done! SimpleSync does the rest automatically.

SimpleSync keeps the inventory in sync fast for items that share an SKU.
Sell an item through multiple product pages.
Inventory tracking for simple bundles where one item has tracked inventory.

Pros

Keeps inventory of items in sync effectively
Simple to use by just giving products the same SKU in Shopify admin
Helps to sell more by allowing product pages to target different demographics (eg, men and women)
Fast synchronization for items that share an SKU
Supports selling an item through multiple product pages
Tracks inventory for simple bundles where one item has tracked inventory

Cons

Potential issues if SKUs are not managed properly
May not be suitable for complex inventory management needs
Requires careful setup to ensure products are properly linked

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.

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.

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.
