Why this happens
OpenAI separates personal ChatGPT billing from Business workspace management. The correct cancellation controls are under the workspace's settings and billing, accessed by an owner. Identify the billed workspace before proceeding, since other members may rely on its features and a personal account can also have separate purchases.
What to do
- Read the invoice to identify the Business workspace and confirm that the acting user is its owner.
- Open the workspace settings, then Billing and Manage plan, and review Cancel subscription and its stated effective date.
- Complete the intended cancellation and communicate the confirmed access end date to members who depend on the workspace.
Check the result
Save the workspace confirmation separately from personal-plan records. If you are not the owner, ask the authorized owner to handle the specific workspace rather than deleting your own ChatGPT account.
