Add a payout bank account
Add an additional destination bank account to the organization's existing payout account. Country and currency are resolved from the organization. The full account number is never returned — only `last4`.
Update invoice status PUT
Mark an outstanding invoice as "paid" or "void". Cannot change the status of already paid or voided invoices.
Complete payout verification POST
Provision the organization's payout account in a single call with the full KYC + bank payload. Uploads the identity document, persists the destination bank, and creates the connected account through the org's payout provider. The account starts `pending_verification` and flips to `verified` via the provider's webhook. Idempotent: returns the existing account if the org already has one.
