Add the knowledge base module to your client portal. Create a help center only accessible by clients. Replaces Zendesk.
The knowledge base module lets you create articles that are visible to your clients. Mostly commonly, it is used as a help desk, support center, and FAQ center, but you can use it for any content you like. Articles can have rich text, images, and videos. And clients can upvote/downvote content so that you gain insight about what content resonates best.
