Consider the following example where Product A, Product B, and Product C all share the same SKU, meaning they represent the same physical inventory.
Initial Inventory Distribution
Product | Location A | Location B | Location C | Total |
|---|---|---|---|---|
Product A | 10 | 50 | 0 | 60 |
Product B | 10 | 10 | 40 | 60 |
Product C | 30 | 0 | 10 | 40 |
Example Scenario
Let's say a customer places an order for 20 units of Product A.
Shopify deducts inventory from Product A based on its configured inventory locations.
After the order, Product A inventory becomes:
Product | Location A | Location B | Location C | Total |
|---|---|---|---|---|
Product A | 10 | 30 | 0 | 40 |
Inventory Synchronization
The Duplicate SKU Sync app then updates Product B and Product C so that their inventory distribution matches Product A for each location.
The updated inventory becomes:
Product | Location A | Location B | Location C | Total |
|---|---|---|---|---|
Product B | 10 | 30 | 0 | 40 |
Product C | 10 | 30 | 0 | 40 |
Why This Happens
The app assumes that products sharing the same SKU represent the same physical inventory, even if they exist as separate product listings.
For this reason, Duplicate SKU Sync keeps both:
- Total inventory quantity
- Inventory distribution across each Shopify location
identical for every product sharing the same SKU.
Benefits
- Synchronizes inventory across multiple Shopify locations.
- Maintains identical stock distribution for duplicate SKUs.
- Prevents inventory inconsistencies between duplicate products.
- Helps reduce overselling across locations.
Note: Duplicate SKU Sync synchronizes inventory per location, ensuring that products sharing the same SKU always reflect the same stock levels and location-wise inventory distribution.
