SharePoint 2016 has a new UI and a new way to Create Sites or Subsites. You can use a wiki page to collaborate really effectively because it's easy to access information and share it with others in your team. You could set up individual client pages and allow them to be edited by anyone; this would be pretty convenient for building your client profiles and constantly adding relevant and important information after client meetings, etc. It would help ensure your team is always on the same page
