The various sources of cases are the different means through which a customer contacts a company.
Cases are generally generated through telephone calls, website portal visits and e-mails. In general, case trouble tickets are used to capture customer feedback on various types of issues that arise after purchasing a product or service from your company.
Here are the different ways to add cases:
Customer phone call: Add a case manually, based on the telephonic conversations that you've had with customers.
E-mail message: Add a case manually, using the Outlook Plug-in when a customer sends an e-mail to your Outlook mail client.
Website portal: Capture the cases from your website using the Web–to–Case form.
