Adviser's Manual 360 licenses are valid until the end of the month, one year from the date of purchase. So, if you buy a license on August 5, 2024, that license would be valid until August 31, 2025. If you renew a license before it expires, the license will be renewed until one year beyond its current expiration date.
Note: The expiration date shown in your My Info zone within the Manual reflects your subscription paid thru date. Subscriptions are billed and invoiced based on that date. There is, however, courtesy 60-day grace period following your subscription paid-thru date during which you will continue to have access to the Manual, which should leave plenty of time for your renewal payment to be processed!
