The Kometrics Blog
Guides on SaaS metrics and revenue analytics, from the team building Kometrics.
Gross churn vs net churn: the leak, and what covers it
Gross MRR churn measures what you lost; net churn subtracts the expansion that covered it. Formulas, a worked example, negative churn, and why quoting only one of them misleads.
Paddle vs Stripe for SaaS: merchant of record or payments platform
Paddle and Stripe are different species: one becomes the seller and handles global tax for 5% + 50¢, the other gives you the best payments infrastructure and leaves compliance to you. The real comparison, with the math.
Bookings vs revenue: what you sold, what you earned, and what hit the bank
Bookings measure commitments, revenue measures delivery, and cash measures timing. The differences explained with one annual contract, plus where MRR and ARR fit in the picture.
Involuntary churn: the revenue you lose to failed payments, and how to get it back
A meaningful share of SaaS churn is cards failing, not customers leaving. What involuntary churn is, the free dunning fixes to configure first, how to measure your past-due exposure, and when paid recovery tools earn their fee.
Stripe Sigma explained: what it does, what MRR costs in SQL, and when you need it
Stripe Sigma is SQL over your Stripe data, right in the dashboard. What it is great at, what its own MRR template really involves, and how to decide between Sigma, a warehouse, and a subscription analytics tool.
MRR vs ARR: which one to track, and when each one lies
MRR and ARR are the same number in different units, until they are not. When to use each, how annual contracts break the conversion, and the mistakes that make either one wrong.

NRR vs GRR: the two retention numbers, and why you need both
Net revenue retention and gross revenue retention answer different questions: one measures growth from the base, the other measures the leak. Formulas, a worked example, benchmarks, and which one to quote when.
