Much like subletting an apartment, customers can tap their friends to take over membership payments.
Here's how to make this happen:
Head to the customer's profile who currently has the subscription or pack > click the dropdown menu to the right of the membership > click Move to other customer
Choose who its going to.
If this is an auto-renewing membership and no card is found on file, Momence will warn you that this customer receiving the membership will need to add a card before the next renewal (or they'll lose the benefits).
If you then navigate to the receiving customers profile, you'll see the new membership listed with the last renewal payment (for the current billing cycle) attributed to the previous customer.
We can see below that the membership will renew on the 24th and will attempt to charge Jane's card on file.
