Resurrected recurring revenue (ARR or MRR) is the recurring revenue added from former customers who returned in a period. Resurrection is not a very common or important metric for SaaS companies that sell to enterprise, as it’s relatively rare and when it does occur, it typically requires a whole new sales cycle. However, tracking resurrected MRR is important for companies that sell monthly SMB and consumer SaaS products, as customers often come and go, and reactivating churned customers can be a more efficient growth strategy than marketing to net new customers.
