Symptom
MRR is growing while deferred revenue balance grows faster and active product usage declines indicating revenue is being reported at billing events before value is delivered.
Cause
Billing-based revenue recording recognizes annual and prepaid subscription revenue at the billing moment rather than as product delivery occurs creating a growing gap between billed and earned revenue.
Impact
Revenue is overstated by 15–30% relative to earned value in high prepay or annual billing models and the overstatement becomes visible only at renewal when low-usage customers fail to renew.
