The "Minimum FBA inventory" setting in the SKU settings only refers to the stock you have in the Amazon FBA warehouse.
So if you have enough stock in the FBA warehouse and your stock is OOS, it does not mean that you will necessarily get a reorder recommendation.
It all depends on how high your sales are in relation to the stock. You can influence your sales manually. Either in the SKU data:
or in the sales forecast for your SKU:
You can additionally set the safety (buffer) stock of warehouse or FBA warehouse in your SKU data:
If you manually set your sales to 30 per month with the safety stock levels set above, VentoryOne will suggest a Purchase Order if your total stock (FBA stock + inventory) is less than 30.
If your FBA inventory is less than 14, an FBA Send-Ins will be recommended to you.
