Use different Shopify Locations for each platform
All platforms (Shopee, Lazada & TikTok) do not allow stock changes during promotions. This might be a problem if you are selling across different platforms and do not have enough stock.
To prevent this I recommend setting up different Shopify Locations for each platform and syncing stock from those locations.
- To do this, make sure "Inventory from one Location" is enabled
- make sure the correct Shopify Location is selected
Do the same for the other platforms, e.g. Lazada warehouse for Lazada stock. TikTok warehouse for TikTok warehouse etc. The idea is to make sure that they do not share stock so selling out on one platform does not create stock shortage for other platforms too.
