What it unlocks
Comparable visitor economics
GA4 supplies the visitor denominator, acquisition and geography
breakdowns, previous-period comparison, and a separate realtime
indicator. Pair it with Stripe, Lemon Squeezy, or Polar for trusted
transaction revenue and with the server SDK for AI cost.
Current limits
Today is included, but not finalized
Today and Last 7 days views include today. Recent GA4 data can be
delayed or revised; an included current day is provisional, not a
finalized total. Separate complete-window comparisons can lag the
live view. Compare the actual reporting window, time zone and
data-as-of time across analytics, payments and AI usage.
Realtime users remain a separate indicator. GA4 revenue alone
cannot establish complete customer contribution.
