Can the plan exclude the zero-quantity products/not online products?

Basically, our app counts both  Active and Draft products, no matter if they are in-stock or not. Because even though those products are out-of-stock, we still need to dedicate resources to store, sync, and process all product data in your inventory. What exactly counts as a product?

The workaround to exclude products from the plan is you could either delete unnecessary products or archive them. Otherwise, you need to upgrade to a higher plan. 

The  Archive product button should be found at the end of the product page. Learn more via this Shopify article.
