What is the difference between a contract renewal and an upsell?
A contract renewal extends the existing scope past the current term end date. An upsell adds net new scope, usually in the middle of an existing term. The two often happen together at the renewal moment because the commercial window is open, but they are different motions on the record. The renewal is counted as retained revenue. The upsell is counted as expansion revenue. Mixing them makes the forecast noisy and the retention math wrong.
