Sales Leads Database

My ex-boss at work who used to be in Quality (and had a hand in everything else), is now in Sales and has decided to take on the task of creating a sales lead database for all the customer service and tech reps to keep track of calls. He decided not to use some of the existing software that the company had purchased, but to make his own. Jimmy may have to use this database, so I'm sure I'll be hearing about it from him and the others - I'll let you know how it's working...
