Veeqo will allow you to accept pre-orders from BigCommerce for products that you currently have no physical stock for in your location. That means your real stock of 0 is set correctly in Veeqo, but the item will still be available for purchase on your BigCommerce.
Your pre-orders will come into Veeqo as Waiting For Stock and therefore sit separately from your Ready To Ship orders, to avoid any confusion.
How to enable pre-orders on BigCommerce?
1. Log into your BigCommerce Admin;
2. Go to your Products page on BigCommerce Admin;
3. Under the Inventory section, make sure that the Track inventory option is checkbox is unchecked;
4. Click on Save.
Orders for these pre-order products will go into Waiting For Stock and once you receive stock Veeqo will automatically assign stock based on oldest order first until all available stock is allocated.
