Does anyone know of a descent, light-weight, billing and invoicing script that would be easy to integrate into an existing app I’m working on? It would need to work with [Authorize.net](http://Authorize.net) and I’d want to hack it up so that it reads from an existing user database. I don’t want to jump into writing my own until I know it’s the best choice.
