Greendizer is a simple REST API that allows you to build invoices, messages, budgets and payments inside any application.
Applications invoicers and third party developers can build range from incorporating invoice sending into their workflow, to building dashboards deeply integrated with their billing and CRM systems.
Greendizer comes with a set of powerful HTML5 applications - built with this very same API - and makes it easy for them and their users to instantly access their data.
It relies exclusively on standards and can be plugged to any existing system. The layout and design of invoices is customizable using XSL.
The Greendizer API documentation is available upon request during its beta testing phase.
