What Business Software Runs Your Office?

bardkerbie asks: "I work as a webmaster and sysadmin for a small computer services shop (4 employees including the owner). We're to a point in the growth of our business where we need a system for tracking work orders as they come in and out of the shop, specifically inventory used and time spent. We use Quickbooks Pro 2006 for our accounting and payroll software. I've played around with a number of issue-tracking and CRM suites, including Bugzilla, Eventum, SugarCRM and vTiger, but all seem like they lack one critical piece to handle the workload we have. What do you use for tracking the work you do? Is it something you wrote yourself? Is there an open-source project that works well, or is there a Quickbooks plug-in we can purchase?"
