MRR
Monthly recurring revenue from active subscriptions.
Quick answer
MRR means monthly recurring revenue. In SaaS acquisitions, buyers use MRR as a starting point for valuation, but they still need to verify churn, refunds, failed payments, customer concentration, and whether revenue will transfer after the seller leaves.
What is MRR?
MRR is the subscription revenue a SaaS business expects to receive each month from active recurring customers. Buyers use it to understand revenue size, but MRR must be checked against churn, refunds, discounts, failed payments, and customer concentration.
In Vibe Coding
For AI-built SaaS acquisitions, MRR is useful only when the buyer can verify the payment data and confirm the product keeps working after transfer.
Example
A product with 100 customers paying $30/month has $3,000 MRR before churn, refunds, and fees.
Why this matters
This matters because MRR appears repeatedly when building, deploying, debugging, or connecting services in vibe coding workflows.
