Chargify is a powerful recurring billing system designed for Web 2.0 and SaaS companies. Its extensive features include support for trial periods, automatic proration if customers upgrade/downgrade during a billing cycle, credit card payments failure communication, hosted payment pages, complex coupon logic, and much more.

Left Hook Digital is a Chargify power user. We built a robust conference registration system around Chargify that included a very flexible and complex discounting regime that required the creation of instant coupons via API. We’ve also built custom Zapier actions to complete a multi-step workflow.
