Hello, Stewart!
CS-Cart has the Recurring billing feature which may suit your needs. This feature is especially useful for membership fees, subscription services, hosting plans and other items where customers receive ongoing value. Recurring plans can be applied to any number of products, and each individual product can also be associated with several subscription plans.
To find detailed instructions on setting up the Recurring billing addon, please refer to the following page of our Knowledge Base:
