You can do pre-orders with the Waitlist feature by simply setting the inventory count for the product to 0 in Shopify:

This will automatically trigger the waitlist message for anyone who comments for it:
Then when you get the product in stock. Update the inventory appropriately in Shopify. This automatically triggers the "back-in-stock" messages for anyone on the waitlist:

You can wait up to 1-year to get your inventory. And the app will appropriately message everyone when you update the inventory.

Selecting this option avoids the waitlist, and lets the shopper check out to purchase. And then you would fulfill the order when inventory becomes available
