What this tile shows
Worth comparing against what shipping actually cost you, which Squizzie cannot see.
Squizzie calls this one Shipping Revenue. It reads as a money figure in your shop currency.
Where the number comes from
WooCommerce Orders. Order data including revenue, counts, and averages.
What you need for it to appear
Nothing beyond Squizzie and the shop data it already reads.
Charting
