SaaS Rails Kit

The SaaS Rails Kit is a software as a service "starter kit" that provides a pain-free way to add subscription management, recurring billing, and credit card management functionality to any Rails app, so developers can quickly build membership-based web services using Ruby on Rails. Features: -No local credit card storage. - Automated billing script runs nightly for anniversary billing. - Automated notification and retry of failed renewals. - Free accounts and one-month trials are supported. - Optionally collect payment information for paid accounts at account creation. - Easy customization of plan levels — pricing and custom limits. - Ability to tweak limits and fees per account. - Self-serve account creation. - Self-serve account upgrades and downgrades, with limit checking to prevent downgrading to a plan for which the account does not qualify, based on the plan limits. - Account lookups by subdomain. - SSL protection of account creation and login.
