What this tile shows
Needs your cost of goods recorded, either in WooCommerce’s own COGS support or a COGS plugin. Squizzie reads costs, it does not invent them.
Squizzie calls this one Profit. 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
This one charts as well as tiles, so it can go on a report as a figure, as a graph, or as both.
The fuller picture
This is one figure out of a bigger subject. Revenue is not profit covers it properly.
