Accrue — billing state, modeled clearly.
Accrue is an open-source Elixir/Phoenix payments and billing library built idiomatically for the Elixir/Ecto/Plug/Phoenix ecosystem. It gives Phoenix SaaS developers a batteries-included jumpstart for everything a real SaaS business needs on day one: subscriptions, checkout, invoices, coupons, emails, PDFs, webhooks, admin UI, and telemetry — without the migration pain and design regrets earlier libraries accumulated.
Public APIs live on modules such as Accrue.Billing, Accrue.Events,
Accrue.Mailer, Accrue.PDF, Accrue.Auth, and Accrue.Processor.
