The user interface is very simple to use, easy navigation of accounts through different plans/billing cycles etc., ability for users with no technical knowledge or experience at all can easily set it up without any issues from their end as well! I would like more options available within plan less itself such as customizing billing cycle length & frequency so we could do away wth manual entry which was time consuming process but its something i believe will be added soon!! Its good option if your clients are not tech savvy people who don't want too many bells n whistles when they signup an account for first-time purchase then this should work just fine! If your client has some basic understanding about what exactly he wants - nothing much needed here!! Simple one stop shop solution where everything related to subscription management, payment tracking / invoicing setup, reporting.
