Commence RM is a powerful and flexible database application for customer relationship management, but it is decidedly dated, and its API is not very user-friendly.
Commence Designer Edition is a particuarly cranky beast that demands super-brittle VBS and DDE approaches to integration and offers little support for modern tooling.
This package wraps the Commence API in a python interface for convenience; a complete installation of Commence is required.
PyCommence is built atop pycommence.wrapper._icommence - a makepy generated Com-Object wrapper - via the win32com package.
