What this tile shows
The number that decides whether a referral programme pays for itself.
Squizzie calls this one Revenue from referrals. It reads as a money figure in your shop currency.
Where the number comes from
Perkie Referrals. Referral counts, conversion rates, and top referrers.
What you need for it to appear
Nothing beyond Squizzie and the shop data it already reads.
The fuller picture
This is one figure out of a bigger subject. Loyalty reporting in Squizzie covers it properly.
