Simple proration for membership upgrades and downgrades to maintain a member’s payment date and adjust initial payment at membership checkout.
When a member chooses to upgrade, they are charged a pro-rated amount for the new membership level immediately and the member’s current payment date is maintained. When a member chooses to downgrade, the initial payment is $0 and the downgrade is delayed until the next payment date. The member’s current payment date is maintained.
Downgrades are defined as having an initial payment less than the current level but can be altered via filters. It assumes that the level’s initial payment is equal to billing amount.
