credit cards: billing owner and seat admin (2026-08-25)

Compare Card checks who owns billing and seats for “amex cards” in credit cards on 2026-08-25 across Nubank, Inter, and C6 Bank. Focus: credit cards. Annual is blocked until a second admin can pay and revoke a contractor.

How Nubank, Inter, and C6 Bank fail admin

Nubank fails with a single personal admin. Inter fails if credit cards cannot move to a company inbox. C6 Bank is the control: if its seat table is empty, stop the shortlist.

Fails that kill card-picks-2026-admin-2026-08-25

• Skipping the second admin on Inter
• Leaving credit cards on a personal card for C6 Bank
• Closing before a revoke test

Go / no-go 2026-08-25

Annual only if a company inbox owns billing and a second admin can revoke seats for “amex cards”. Otherwise card-picks-2026 stays monthly until credit cards is not on a personal card.
