Under your Account Settings click on the Option section and you will find a setting in the third row called, “Membership Renewal Grace Period (Days)”. When a numeric value is entered and saved it will allow for a specific amount of time between the expiration of an existing membership and the purchase of a renewal membership for when the start date of the renewal transaction will be automatically set to the day after the expiration date of the previous membership transaction. This way there is no gap shown between the expired memberships and renewal membership, as if the renewal membership was purchase on time.
