ARR annualizes your active recurring contracts at a point in time; GAAP revenue is what your books recognize as earned in a period under ASC 606.
Key takeaways
ARR annualizes your active recurring contracts at a point in time; GAAP revenue is what your books recognize as earned in a period under ASC 606. ARR is a forward-looking run-rate for investors; revenue is the audited number on your income statement. They rarely match.
A customer signs a 12-month, $120K deal on July 1. ARR jumps $120K immediately, but GAAP revenue recognizes only $10K per month as the service is delivered, so this year's revenue from the deal is $60K while ARR reads $120K.
ARR is a non-GAAP management metric; only recognized revenue under ASC 606 appears on audited financial statements.

Founders pitch ARR but get funded, and audited, on revenue. Confusing the two overstates the business and triggers painful restatements in diligence or at tax time. Clean books reconcile ARR to recognized revenue and deferred revenue every month so both numbers hold up.
