- Implement invoicing, payments, retries, and dunning workflows.
- Model taxes and compliance requirements per region.
- Validate with sandbox payments and reconcile ledger outputs.
- If detailed templates are required, open `resources/implementation-playbook.md`.

## Safety

- Do not charge real customers in testing environments.
- Verify tax handling and compliance obligations before production rollout.

## Resources

- `resources/implementation-playbook.md` for detailed patterns, checklists, and examples.
