No. All versions of s2Member Pro are sold with a one-time charge; no recurring fees.

Lifetime Updates + 12 Months of Support

When you purchase s2Member Pro, you receive lifetime software updates and one year of support. After one year, you may continue to use s2Member Pro for as long as you wish, and you will always have access to the latest version of the software. However, if you need ongoing support, a small renewal fee is required. Please check your "My Account" page for details.

Note: You may choose to renew, or not. Renewals do not occur automatically. If you do choose to renew (i.e., you need ongoing access to support) the rate is just $19 for a Single-Site license, and $29 for the Unlimited-Site license.
