Can this skill handle complex proration logic?

Yes, it provides logic patterns for calculating prorated charges when users upgrade, downgrade, or change seat counts in the middle of a billing cycle.

What is dunning management in this context?

It is the automated process of recovering failed payments through retry schedules, customer notifications, and grace periods to minimize involuntary churn.

Does it support international tax calculations?

It includes implementation patterns for common tax jurisdictions including US Sales Tax, UK/EU VAT, and Australian GST.

Is this specific to a particular payment provider like Stripe?

While the code patterns are compatible with providers like Stripe, the logic is designed to be provider-agnostic so you can implement it with any billing API or custom backend.
