Question concerning Leads, Accounts and Contacts

Question concerning Leads, Accounts and Contacts

We're a B2B COTS sales and support company, we've had one shot at setting up Zoho to meet our needs and now I'm looking at how we can make better use of the application.

The questions are:

Q1. I have situations where a Lead has multiple contacts when selling at various levels in the organisation. It seems that I need to setup a separate Lead for each individual. Is there a way of connecting multiple Leads in one organisation? Do I use Account? My interpretation of Account is what happens when a Lead is converted through a sale into an Account.

Is there somewhere I can read through how this process works in Zoho.

Thanks,
Anthony
