Now that leads can be organized and scored in your CRM, the next step for sales reps will be to reach out to the priority leads over phone or email. Tracking conversations—when was the last email or phone conversation, what did you speak, did they read your email—is an advantageous feature to know how to strategically plan your next course of action.
Prospecting and marketing are all the things you do to get people into the first of your sales funnel stages. Note that stages are broken into two or more steps wherever possible. A demo could be called a single stage, but in real life it involves a lot of things: contacting the customer, sending reminders, doing the demo, and then following up. Whatever your own sales stages look like, the support you need in managing them will be the same.
