I’m trying to sync a number of products with our new wholesale site (not all products will be sold wholesale). I’m just using the free version at the moment, just to get a feel for how the plugin works and if it’ll service our needs, but will inevitably need to upgrade once working correctly. I don’t want to push all products to the wholesale site, given they won’t all be available for wholesale. To start with, I have selected 2 products to test with. The problem happened with both: I pushed them from aussiefoods.eu (retail + primary inventory) to aussiefoods-b2b.eu (wholesale + secondary inventory), and it reset the stock of these to 0 on both sites. When I went back to the product by the primary and re-entered the stock levels, this amount then also came through on the secondary. Why is the primary stock being set to 0 when I push it through to the secondary?
