billing-automation

Automate recurring payments and subscription lifecycle management by using Python classes like Subscription and BillingEngine to handle trial periods, active states, past-due statuses, and cancellations. This reduces manual billing overhead and improves cash flow.

Dunning management handles failed payments by implementing automated retry schedules and customer notifications. The DunningManager class orchestrates these retries to recover failed charges gracefully without manual intervention.

Calculate prorated charges and taxes using the ProrationCalculator and TaxCalculator classes. These components generate accurate invoices for billing cycles, ensuring customers are billed correctly for partial subscription periods and applicable taxes.

Yes, you can track and bill metered usage based on defined pricing models. The Skill supports usage-based billing, allowing you to monitor consumption and automatically generate invoices according to your specific metered pricing structure.

Create a new monthly subscription with a trial period by instantiating the Subscription class with the customer ID, plan ID, and trial duration parameters. The BillingEngine then manages the transition from trial to active billing automatically.

The approach automates SaaS billing cycles including invoicing, proration, tax calculation, and dunning, but relies entirely on Python class implementations without external dependencies. Complex custom pricing tiers may require extending the core classes directly.
