The flat monthly connector fee can be billed at the user group level, paid by the group's Financial owner, for the chargers scoped to that group. This extends the account-level connector fee down to the group, so an operator running several sub-customers under one account can charge each group's Financial owner for their own chargers' hardware fee. A single Financial owner covers both members' charging sessions and the connector fee.
Two independent billing sections: The Edit group dialog has two collapsible sections: Member billing (charging the owner for members' sessions, as before) and Connector billing. Each has its own enable toggle, and only one is expanded at a time. Either or both can be enabled.
Read-only charger list: Connector billing lists the group's chargers (charger ID and site). Chargers join a group only through Charger scope = Groups, so to add or remove one, change that charger's scope.
Fee and tax: When connector billing is on, set a monthly fee and an optional tax rate (labeled VAT, GST or Tax according to the operator's country).
Financial owner required: The connector billing toggle stays disabled until a Financial owner is set. Clearing the owner disables it and shows a notice.
No double-charging: A charger's connector fee is billed either through its group or through the account, never both. Group-billed chargers drop off the account connector total, and the Account billing screen shows a note and count explaining the reduction.
What the owner is billed: On the monthly run, the Financial owner is charged (billable connectors × monthly fee) + tax, shown as a Connector fee line item on their statement.
Chargers in more than one group: These cannot be billed until reassigned to a single group. The save is blocked with a message listing the affected chargers.
