MiniBill - Billing SoftwareMiniBill is a great companion to your business as much as your business requres recurring billing.
Right now it supports Authorize.net as the recurring billing gateway but is easily extendable to use others. It is written to be pluggable, small and affordable.
It is extendable through PHP using smarty templates and a very simple database schema.
