Subscription billing is the automated management of recurring revenue where customers pay periodically for products or services. Subscription models have become increasingly popular because they provide predictable recurring revenue, improve customer lifetime value, and create alignment between customer success and company success. However, subscription billing is complex, requiring automation for recurring charges, failed payment handling, and customer lifecycle management.
Subscription Models
Different subscription models exist:
Fixed plans - Customers choose from predefined plans (Starter, Professional, Enterprise) with set features and pricing.
Usage-based billing - Customers pay based on actual consumption (API calls, storage, users). Pricing scales with customer value extraction.
Hybrid models - Combining fixed base fees with usage overages. Ensures baseline revenue whilst scaling with customer growth.
Freemium - Free tier with limited features, premium tier adding advanced capabilities. Converts engaged free users to paying customers.
Time-based subscriptions - Annual, monthly, or per-use billing at customer preference.
Each model has tradeoffs - fixed plans provide predictability but may be suboptimal for some customers; usage-based aligns pricing with value but creates unpredictable monthly bills.
Core Subscription Features
Successful subscription platforms require:
Recurring billing - Automatically charging customer payment methods at regular intervals.
Failed payment retry - Handling failed charges through automatic retries, dunning emails, and manual recovery approaches.
Plan management - Supporting plan changes (upgrades, downgrades, pauses) mid-subscription.
Proration - Calculating charges fairly when subscriptions change mid-period. Upgrading mid-month requires fair proration.
Cancellation - Handling voluntary cancellations, including exit surveys, retention offers, and clean offboarding.
Invoicing - Generating detailed invoices and statements for customer records and tax compliance.
Tax compliance - Calculating and remitting sales tax, VAT, or GST based on customer location and product type.
Dunning Management
Failed payment recovery is critical:
Automatic retries - Most payment processors offer automatic retry logic, attempting failed charges multiple times.
Retry schedules - Configurable schedules determine how many retries occur and over what period.
Dunning emails - Sending customers emails asking them to update payment information.
Payment forms - Providing secure payment form links allowing customers to easily update payment information.
Recovery strategies - Some customers resume payment when reminded; others abandon. Sophisticated dunning distinguishes between them.
Churn prevention - Identifying at-risk customers before cancellation to enable retention efforts.
Usage-Based Billing Complexity
Usage-based models add complexity:
Usage tracking - Instrumenting applications to track customer usage (API calls, storage, compute).
Real-time pricing - Calculating pricing based on actual usage rather than fixed plans.
Meter aggregation - Combining usage across multiple sources into unified billing.
Price changes - Managing mid-month price changes, ensuring fair recalculations.
Forecasting - Helping customers forecast their bills based on current usage trends.
Subscription Retention
Keeping customers is more cost-effective than acquiring new ones:
Onboarding - Helping customers succeed immediately after signup reduces early churn.
Engagement tracking - Monitoring feature adoption and usage patterns to identify at-risk customers.
Proactive support - Reaching out to struggling customers before they consider cancellation.
Feature releases - Regularly releasing new features creates reasons for continued engagement.
Value communication - Regularly demonstrating value extracted, helping customers justify continued investment.
Subscription Economics
Subscription business models have distinct economics:
Monthly Recurring Revenue (MRR) - Total subscription revenue expected monthly, critical for predicting company revenue.
Annual Recurring Revenue (ARR) - MRR multiplied by 12, indicating expected annual revenue.
Churn rate - Percentage of customers cancelling each month. Low churn enables exponential growth; high churn requires constant acquisition.
Customer Lifetime Value (CLV) - Average revenue per customer over their subscription lifetime. Higher CLV enables higher customer acquisition spending.
Expansion revenue - Additional revenue from existing customers through upgrades, cross-sells, or add-ons. More cost-effective than acquisition.
Subscription Platforms
Specialised platforms simplify subscription management:
Stripe Billing - Comprehensive subscription management through Stripe, handling recurring billing, dunning, and invoicing.
Chargebee - Dedicated subscription management platform with advanced features.
Zuora - Enterprise subscription management for complex billing scenarios.
Custom development - Building in-house enables full customisation but requires significant development.
Subscription Lifecycle
Customer subscription journey:
Signup and onboarding - Customer joins and begins trial or paid subscription. Onboarding experience affects early churn.
Engagement - Customer actively uses product, finding value and justifying ongoing payment.
Expansion - As customer value extraction increases, they upgrade to higher plans or add features.
Plateau - Customer settles into consistent usage. Engagement becomes stable.
Decline - Usage decreases, indicating potential churn. Intervention may recover the customer.
Cancellation - Customer stops paying. Understanding cancellation reasons informs retention strategies.

Regulatory Compliance
Subscription businesses face compliance requirements:
Consumer protection - Clear billing information, easy cancellation, and transparent terms required by law.
Tax compliance - Sales tax, VAT, and GST requirements vary by location.
Payment compliance - PCI compliance and data protection requirements.
Automatic renewal laws - Some jurisdictions have specific requirements for subscription disclosures and cancellation.
Reducing Churn
Subscription success depends on minimising churn:
Product quality - Products that genuinely solve customer problems have lower churn.
Customer success - Helping customers extract value from your product improves retention.
Pricing alignment - Fair pricing aligned with customer value extraction improves retention.
Customer support - Responsive support resolves issues before they cause cancellation.
Regular communication - Demonstrating value through updates and releases reminds customers why they pay.
Conclusion
Subscription billing automates recurring revenue, providing businesses with predictable income and aligning company success with customer success. However, subscription models require sophisticated billing systems, proactive churn management, and continuous customer success efforts. Organisations that master subscription models gain significant competitive advantages through recurring revenue and customer lifetime value.
