We've pushed an update to EZ Inventory's "Activity Log Details" page to show a summary count of items by update status (e.g. success, failure, skipped, removed).

You can also find a link on this page that allows you to quickly download a list of items that exist in the source data/inventory feed, but weren't found in Shopify.

In most cases, a supplier feed will contain a lot more items that the merchants carry in their store, so the merchants don't usually care what those missing items were as they're expected to not exist in Shopify.  But there are some cases where they do want to make sure all or most of the items in their supplier feed also exist in their Shopify store, or iif they sync items from their own separate warehouse system and they want to make sure their Shopify store has all of them.

This new download link makes it very easy to figure them out.  It simply spits out a text file listing all item IDs from the feed that weren't found in their Shopify store.

Below is a screenshot showing where this link is:

The output will be a text file that looks like this:
