Loading...A reduction in recurring revenue from an existing customer through a tier downgrade, seat reduction, or product de-scoping that retains the customer but at a lower commitment. Downsell sits between expansion and churn in the customer base movement model and is the operative measure of preference-driven contraction. The federation requires downsell to be tracked separately from churn and from the expansion class with which it can be confused, and reported in the MRR roll-forward under UFMS-001:3.2. The downsell trend is a leading indicator of broader retention risk.
An inversion of the upsell construction in subscription business vocabulary; the term was crystallised in customer success management literature in the 2010s.
Federation members track downsell separately from churn. Downsell trend is reported in the MRR roll-forward under MEV-Annex:4.1. Cohort downsell rates are reviewed at the steward tier accreditation cycle as a leading retention indicator.
