Who can change billing settings and issue refunds?

Super admins handle invoices and refunds; center admins handle the billing setup around them. The split, from most to least restricted:

• Organization owner only: currency, country, outbound email language, tax ID, and legal name and address under Settings.
• Super admin: creating, editing, sending and voiding invoices, Generate invoices, auto-invoice settings (enable, Generate Ahead, Due After, Auto-Send), the Upcoming view and Skip, refunds (online or recorded by hand), and payout accounts and payment settings on Finances.
• Center admin: billing plans, discounts, subsidies and payers, family credits, the late-fee policy (amount, grace period, and the auto-apply toggle), marking invoices paid, and applying credits to an open invoice. They can also change the organization's timezone, which sets when auto-invoicing runs.

Gotchas this explains:

• A center admin sees Create Invoice, Void Invoice, Refund and the Auto-Invoice Generation panel, but saving is refused with a permission error. That is the current split, not a glitch: ask a super admin.
• Refunds are super admin, not owner-only. Any super admin can issue one.

If a director genuinely runs your billing, make them a super admin rather than fighting the boundary.
