This is a small (demo) rewrite of a Customer Relationship Management (CRM) system I built years ago; initially for managing my own customers while running a web development firm. In later iterations, it also supported billing with PayPal as my primary payment processor integration and even saw some production time as an online service/multi-tenant concept for other small-medium businesses to lease.

As with most of my personal aspirations and entrepreneurial endeavors, however, it lacked both the personnel and funding support to remain active for any length of time.
