A recurring membership service is one that automatically bills the customer every 30 days, until the customer cancels their membership. Members can cancel their subscription anytime simply by clicking the subscription cancel link in the member's area .
Also note that 30 days is the minimal and the fixed subscription duration interval or cycle. Meaning, a cancelled subscription continues to be active until the duration interval of 30 days elapses except when a refund is requested and therefore membership stops immediately. See the Refund policy below.
Refund policy
Nabla gives a registered member an opportunity for a full refund within the first 24 hours the initial subscription is accomplished. Refund may be issued from the Sale Detail page for the order.
