Using "Reserve items" to prevent cart stealing
Each draft order created by SoldLive has a "Reserve items" link in Shopify:
This lets you reserve the items for a certain period of time:
What it does: if a new person attempts to purchase it before the reservation has expired, they will see an error at checkout letting them know an issue with the inventory is preventing their purchase from completing.
Note this will not take the product out of inventory in Shopify. The product will still appear to be in stock on the storefront. This is because the item has not yet been purchased and could be bought in the future by a different customer.
When you need to do this: if shoppers are going outside of your live by buying directly on your website, this will prevent them from doing so. There are other ways to prevent this "cart stealing" as well
