Re-engagement campaigns are targeted efforts to reconnect with inactive customers through personalized messaging. They aim to restore interest, prevent churn, and bring dormant subscribers back to active usage.

Smart retry uses intelligent algorithms to automatically reattempt failed payments at optimal times. Unlike basic retries, it considers decline reasons, customer patterns, and success data to maximize recovery chances.

Revenue backlog is contracted future revenue from existing customers that hasn't been recognized yet. It includes remaining value from multi-year contracts and prepaid subscriptions, helping predict future cash flow.

Payment reconciliation is the process of matching and verifying payment transactions across different systems to ensure accuracy. It helps businesses identify discrepancies, prevent errors, and maintain clean financial records

Revenue churn measures the percentage of recurring revenue lost from existing customers through cancellations and downgrades. Unlike customer churn, it focuses on dollar impact, making high-value customer losses more visible.

Net Dollar Retention (NDR) measures how much revenue you retain and grow from existing customers over time. Above 100% means you're growing revenue even with some churn. Top SaaS companies target 110%+ NDR.

Rebill success rate measures the percentage of successful automatic payment attempts for recurring subscriptions. A high rate means fewer payment failures and better revenue retention for subscription businesses.

Expansion MRR tracks revenue growth from existing customers through upsells and upgrades. It shows how well you're growing accounts vs just acquiring new ones. Formula: New MRR from current customers minus churned MRR from current customers.

Involuntary churn occurs when customers are lost due to payment failures or technical issues, not by choice. Unlike voluntary churn, these customers want to stay but can't due to expired cards, failed transactions, or account problems. This creates unexpected revenue loss that businesses can prevent with proper payment recovery systems.
