Real-Time Analytics for SaaS: Metrics, Churn, and Revenue

SaaS companies need real-time visibility into MRR, churn signals, feature usage, and customer health — not yesterday's batch report. A streaming database computes these metrics continuously from product events and billing data, enabling immediate response to churn signals and revenue changes.

Real-Time SaaS Metrics

-- Monthly Recurring Revenue (always current)
CREATE MATERIALIZED VIEW mrr AS
SELECT DATE(effective_date) as date,
  SUM(amount) FILTER (WHERE type='new') as new_mrr,
  SUM(amount) FILTER (WHERE type='expansion') as expansion_mrr,
  SUM(amount) FILTER (WHERE type='churn') as churned_mrr,
  SUM(amount) as net_mrr
FROM subscription_events GROUP BY DATE(effective_date);

-- Churn risk detection
CREATE MATERIALIZED VIEW churn_signals AS
SELECT customer_id, company_name,
  MAX(last_login) as last_active,
  NOW() - MAX(last_login) as days_inactive,
  COUNT(support_tickets) FILTER (WHERE ts > NOW()-INTERVAL '7 days') as tickets_7d,
  CASE WHEN NOW()-MAX(last_login) > INTERVAL '14 days' AND COUNT(support_tickets) > 2
    THEN 'high' ELSE 'low' END as churn_risk
FROM customer_activity GROUP BY customer_id, company_name;

Frequently Asked Questions

Why do SaaS companies need real-time metrics?

Churn happens fast — a customer who stops logging in and opens support tickets is signaling departure. Batch reports detect this days later. Real-time streaming detects it immediately, enabling proactive retention.
