Billing Automation
Implements comprehensive automated billing systems for recurring payments, subscription lifecycles, and failed payment recovery.
The Billing Automation skill provides specialized patterns and logic for building robust financial infrastructures within Claude Code. It enables developers to handle complex subscription states, automate invoice generation, and manage the entire dunning process for failed payments. With pre-built logic for proration during plan changes and multi-jurisdictional tax calculations (VAT, GST, Sales Tax), this skill is essential for developers building SaaS platforms, subscription-based games, or usage-based service models that require high-reliability payment processing.
