Our business runs on limited-editions. As such, we often encounter a situation where we need to make a product as out-of-stock even when we have a bit of inventory left because that inventory might be reserved for something special (influencer package, wholesale customer who hasn't completed order yet, etc).
Essentially, we want to use the Shopify inventory feature to actually manage physical inventory, but we need to be able to toggle actual availability. This also means the customer shouldn't be able to add the item to cart.
Also, we would want to be able to control "back-in-stock" notifications that automatically occur when the inventory value rises above 0. Best case scenario, we would have a checkbox on the product page that we would tic when the item becomes unavailable and the "back-in-stock" notifications would look at this before sending an email.
Are there any apps or snippets available for this?
While you can look for an app in the app store, this is certainly possible with code customization. Contact with DM in case support is needed
