A central and easily accessible knowledge base will add a great value to customer service. You can publish customer experience, troubleshooting documents, frequently asked questions, manuals and procedures for your customers and your users. Your knowledge base will be the extension of your organization.
Clearly categorized articles with efficient key words for quick search will eliminate customer calls, emails and tickets.
You can think of the knowledge base as a never-ending project and improve it constantly to serve your customers without even directly contacting them.
