You can send different inventory levels to different channels based on varying percentages per channel.
For example, if a product has 100 available, and for Amazon you have it set to 70%, SellerCloud can be set to send 70 (and not send the other 30). However, for another product that only has 10 available, SellerCloud will send 7 to Amazon (and not send the other 3). So instead of a specific number safety quantity (like 5 units for all products), the amounts depend on the qty available.
