Does Flo SKU Sync Support Synchronising Across Multiple Product Variants?

Yes. Flo SKU Sync supports inventory synchronisation for product variants that share the same SKU.

If multiple variants in your Shopify store use an identical SKU, the app automatically detects them and keeps their inventory levels synchronised.

How It Works

Whenever the inventory of one variant changes due to a supported inventory event, Flo SKU Sync updates the inventory of all other variants sharing the same SKU, ensuring they always display the same available stock.

Inventory is synchronised when:

  • An order is placed.
  • A refund or restock is processed.
  • Inventory is updated through the Flo SKU Sync dashboard.
  • Inventory is changed in the Shopify Admin.
  • Inventory is updated by another supported Shopify app.

Example

Suppose you have three product variants with the same SKU:

Variant

SKU

Inventory

Blue – Small

SKU-123

25

Blue – Medium

SKU-123

25

Blue – Large

SKU-123

25

If the inventory for one variant changes to 20, Flo SKU Sync will automatically update the remaining variants to 20 as well.

Benefits

  • Keeps inventory consistent across duplicate variants.
  • Reduces manual inventory management.
  • Helps minimise the risk of overselling.
  • Automatically synchronises inventory in real time.

Note: Variants must have exactly the same SKU for Flo SKU Sync to recognise them as duplicates and synchronise their inventory.
