If changes are made to a membership type that has not been utilized for existing memberships, what does NOT carry over to those existing memberships?

The correct answer focuses on the distinction between updates made to a membership type and their impact on existing memberships that have already been activated. When a membership type is altered, such as updating service types offered, adjusting membership prices, or changing discounts, these changes are typically applied only to new memberships or those that have not yet utilized the service.

The invoice amount for future monthly billings does not carry over to ongoing memberships because these existing memberships operate under the original payment terms when they were initiated. Any changes made after a membership has started do not retroactively affect the agreed-upon invoice amount already established for that membership, thereby providing stability for the customer.

In contrast, modifications to service types, membership prices, and discounts can be incorporated into new memberships or renewals, but they will not impact the financial terms of accounts that have already been billed, explaining why this is the correct understanding of the changes.
