Tasks and timeline
Tasks with due times and reminders, lists, subtasks and a board, and on every contact, deal and task a timeline of comments and changes.
Nothing slips
"Call back tomorrow at 10" is set right from the chat and linked to the contact. At the due time the assignee gets a notification, and overdue tasks have their own filter.
From a chore to a project
Task lists, subtasks with progress, custom fields and your own statuses, and a board grouped by any field. One list can be opened to a client, who sees only that list.
History in one place
Comments with Markdown and pinning, who changed what and when, deal and task events, on contacts, companies, deals and tasks. The record's people and earlier commenters are notified of new comments.
In short
A live bell notification at the due time.
A big step split into small ones, with progress.
Columns by status or any field.
