What to check first
For this issue, start with the active workspace and the relevant settings screen. Use the payment provider's secure billing form. Read the current confirmation or provider error rather than repeating the action immediately. Keep a record of what you tried and its approximate time so an administrator or the support team can identify the request.
Use administrator access
Billing changes apply to the active workspace and require the appropriate administrator role. Confirm the workspace name before opening Checkout or the customer portal.
Change a plan
Select one of the volumes and monthly EUR prices offered by the current catalog. Read the checkout or portal confirmation for its timing and amount. Do not rely on an old screenshot for current billing terms.
If the issue remains
Open the manage your subscription guide for the current product steps. If that does not resolve the issue, contact support. Include your workspace name, the screen, and the approximate time. Do not send passwords, API keys, card numbers, or an unrestricted data export.
