Ask HN: How do you track of multiple sales leads?

What's an efficient way of managing multiple leads? At the moment I'm working as an intern at a startup and part of my responsibility is to come up with a daily "hit list" of companies we will be cold/warm calling.

I compile this list using several other lists (e.g. existing dealers, competitor's vendors, etc.). The only problem is that at the moment we're using an excel workbook to manage this and to me, it doesn't seem very efficient because the hit list sources are in different formats and there's no easy way to output the results into an easy to read report.

Can you guys recommend any alternatives?
