You cannot cancel or change a subscription at the Location level because Location-level billing is not yet available and no subscription or payment management occurs there. Subscription and invoice information lives in the Organisation’s Billing area, accessible from the Organisation sidebar.
Only users with the Owner role can make changes to subscriptions, such as switching billing cycles, changing billing aggregation, or adjusting a Structure’s billing tier. Administrators and Owners can view billing details, but for modifications beyond viewing — including cancelling or changing subscriptions — the Owner role is required.
If you do not have Owner rights, ask your organisation’s Owner to make subscription changes. You can find current subscriptions and invoicing under Billing > Subscriptions, and billing tiers per Structure under Billing > Structures. Payment methods are managed via the external payment portal, opened from Billing > Overview with Manage Payment Methods.
