This is the core functionality of Selro platform where Selro will keep your stock level across all your sales channels. This means if a customer purchase an item from a eBay from an example, stock levels will be reduced from other sales channels e.g Amazon.

Selro uses SKU (stock keeping unit) or custom label (as in eBay) for stock synchronisation.

If you uses different SKUs for the same item across different marketplaces, then you can use the merge functionality to link different SKUs with a master SKU in Selro.

Selro also support bundle/kit items for stock synronisation.
