Looking for a fairly simple Web based system for tracking feature requests, system defects and maintenance tasks for each client.

For example, Client X might have these tasks entered:

FEATURE: Add new Apple TV to Great Room system
FEATURE: Upgrade gate camera; need better night vision
DEFECT: HDMI dropping out in upstairs guest bedroom
MAINTENANCE: fortify IR emitter connections on all TVs

I'd need the ability to assign priorities and report on tasks by account and priority.

Thoughts?
