PulseCheck Glossary

Essential SaaS health metrics, churn definitions, and customer success terminology for indie founders building sustainable businesses.

A

ARR / Annual Recurring Revenue
The annualized value of your monthly recurring revenue, used for valuation, fundraising, and growth reporting.
At-Risk Customer
A customer exhibiting early warning signs of disengagement, such as declining usage, missed check-ins, or support spikes.

C

Churn Rate
The percentage of customers who stop subscribing within a given time period, a fundamental metric for any subscription business.
Customer Churn Rate
The percentage of customers who cancel in a period. Unlike revenue churn, this counts individual customers lost.
Customer Health Score
A composite numerical value that predicts a customer's likelihood to renew, expand, or churn based on behavioral signals.
Churn Prediction
Using historical data and machine learning algorithms to identify which customers are likely to cancel before they do.
Customer Health Dashboard
A unified view displaying key metrics: usage trends, support tickets, NPS, and risk status for individual accounts.
Cohort Analysis
Studying retention patterns among customers grouped by signup date, revealing which acquisition channels drive long-term loyalty.
Churn Cohort
A customer segment that canceled within a specific timeframe, analyzed to identify common characteristics and causes.
Churn Benchmark
Industry comparison standard; indie SaaS businesses should target 5-7% annual churn or lower for healthy unit economics.
Customer Churn Cost
The total revenue impact of replacing lost customers, including acquisition costs, onboarding investment, and foregone LTV.
Churn Window
The period before subscription renewal when customers must actively decide to continue, typically 30-60 days prior.

D

Digital Footprint
The aggregated collection of behavioral signals captured from product usage, support interactions, and communication touchpoints.

E

Early Churn Risk Signals
Behavioral patterns that statistically precede customer cancellations, including usage drops, login frequency, and support tickets.
Expansion Revenue
Additional MRR from existing customers through upgrades, upsells, or add-on purchases, offsetting churn in net retention.

F

Feature Engagement
How actively customers use specific product functionalities. Low engagement with key features correlates with higher churn.

H

Health Score Threshold
The numerical cutoff that triggers automatically generated alerts, enabling proactive outreach to at-risk accounts.

L

LTV / Customer Lifetime Value
The total revenue a business can expect from a single customer throughout their entire time as a subscriber.
Logo Churn
Customer churn. Refers to the count of individual companies or accounts lost, distinct from revenue churn.
Leading Indicator
A predictive signal of future outcomes, such as usage decline or missed milestones, that precedes churn events.

M

MRR / Monthly Recurring Revenue
Predictable revenue collected each month from active subscriptions. The foundation for growth planning and valuation.

N

Net Revenue Retention
The percentage of MRR retained including expansion minus churn. Above 100% means you're growing from existing customers alone.
Net vs. Gross Churn
Gross churn is customer losses alone; net churn subtracts expansion revenue, revealing true retention health.
NPS / Net Promoter Score
A customer loyalty metric based on likelihood to recommend, correlating with retention and referral behavior.

P

Product Adoption Metrics
Indicators measuring how quickly and deeply customers integrate a product into their workflow after initial onboarding.

R

Revenue Churn
The percentage of MRR lost from customer cancellations and downgrades in a given period, often called revenue erosion.
Retention Rate
The inverse of churn rate, showing what percentage of customers continued their subscriptions. Higher is better.
Renewal Rate
The percentage of customers who renew their subscriptions at term end. A lagging indicator of customer satisfaction.

T

Time to Value
The duration from signup until customers achieve their first meaningful outcome. Faster TTV predicts lower churn.

U

Usage Trend
The trajectory of customer product interactions over time. Declining trends are leading indicators of potential churn.
