I want to change the amount that I charge for a subscription
Edit the subscription product and change the price.
Subscriptions that are on auto-renew: When the subscription period ends, the subscription will be automatically renewed at the new price. The member will be notified of the new amount that you are taking, both by WebCollect and by GoCardless.
Subscriptions that are not on auto-renew: When the member renews the subscription, they will place the order at the new price.
