What is dunning management in the context of this skill?

Dunning management is the automated process of handling failed payments. This skill provides logic for retry schedules, customer notifications, and account restriction workflows to recover revenue without manual intervention.

Can this skill handle prorated plan changes?

Yes, it includes a dedicated ProrationCalculator to handle complex scenarios where users change plans or seats mid-billing cycle, ensuring accurate credits and charges are applied.

How does it handle international taxes like VAT or GST?

The skill features a TaxCalculator component that identifies tax jurisdictions (e.g., US, UK, EU) and applies the correct rates for sales tax, VAT, or GST based on the customer's location.

Is this skill specific to any one payment processor?

While the logic is general enough for any billing engine, it includes implementation patterns and examples specifically optimized for integration with the Stripe API.
