The sales process starts from acquiring a new lead through until the close of a sale.
Microsoft Dynamics CRM stores the contact information for new leads, with the capability of tracking the follow-up communications (such as Phone Calls, Emails, and Appointments), and the ability to qualify a Lead into an Account, Contact, and Opportunity.

It keeps Leads in a separate area (essentially quarantined) in order to ensure your main database of Accounts and Contacts does not get cluttered with people your organization doesn’t know.

As part of the Opportunity, you may create a Quote and convert that to an Order and an invoice.
It’s Product Catalog provides the basis for this process. Organizations using this functionality often integrate with their financial software or Enterprise Resource Planning (ERP) software. In this way the product catalog and pricing has a single source, is kept up-to-date, and the complexities of ordering and invoicing are handled appropriately.

The end of the process is typically the close of the Opportunity as Won or lost.

If the opportunity is Won, the Relationship Type on the Account is often changed from Prospect to Customer.
