The process of storing, organizing, and monitoring information about your clients, prospects, and sales leads is known as contact management. In its most simple form, an address book or an Excel or Google spreadsheet with entries for all of the people with whom you do business can be used to handle your contact details. Many companies, on the other hand, prefer to use advanced contact management software. This is particularly useful if you have a large number of contacts to keep track of or several people who need access to the information.
