Expansion
A mid-cycle change — added module, upgraded bundle, raised commitment.
Overview
When a customer changes their subscription between renewals — adds a module, upgrades to a higher bundle version, raises a committed quantity — Revvly records it as an Expansion with a prorated charge or credit. Each Expansion contributes to Expansion MRR, the measure of upsell revenue from existing customers.
