Expansion Revenue
Expansion revenue is the extra recurring revenue existing customers bring in when they upgrade, add seats, or use more. New customers don't count.

Expansion revenue is the extra recurring revenue you earn from customers you already have. It comes from upgrades, added seats, and higher usage. You don't pay to acquire these customers again, so this growth costs less than winning new ones.
Where expansion comes from
- A customer moves to a higher plan.
- A team adds users on a per-seat plan.
- Usage-based charges rise as the customer uses more.
- The customer buys a paid add-on or a second product.
Each of these raises MRR and, over time, ARPA. MRR movements reports show expansion as its own line, so you can see how much growth comes from existing customers and how much from new sales.
Why expansion revenue matters
Expansion is what pushes net revenue retention above 100%. If existing customers grow faster than others leave, revenue rises with no new sales.
Net change from existing customers = expansion − contraction − churn
If a cohort adds $25,000 in expansion, loses $8,000 to contraction, and loses $5,000 to churn, revenue from that cohort grew $12,000. Seat-based and usage-based pricing tend to show more expansion, because revenue grows as the customer's team or usage grows.
