Can this skill handle complex global tax calculations?

Yes, it includes specialized tax calculation logic for various jurisdictions including VAT for the UK/EU, GST for Australia, and Sales Tax for US states like California and New York.

The skill provides a configurable retry schedule that automates payment attempts, triggers customer notifications at specific intervals, and manages account status transitions from 'past due' to 'canceled'.

What payment processors does this skill support?

While the code examples utilize Stripe-style patterns, the core logic and subscription state machines are designed to be provider-agnostic and can be adapted for Braintree, PayPal, or custom gateways.
