Track milestones

Milestones are the dates that matter: a launch, a contract deadline, a phase gate. Each one is a title and a due date with a completion toggle, shown on the project’s Milestones tab and summarized on the project Overview.

Add milestones

1. Open your project and select the Milestones tab.

2. Select Add Milestone, enter a title and a due date, and select Add.

The tab has two views, switchable with the Timeline / List toggle:

• Timeline lays the milestones out as diamonds along a horizontal line spanning the project, with a dashed Today marker showing where you stand. It is the default while the milestone count stays small; projects with many milestones default to List for readability.
• List shows one row per milestone with its due date, a relative countdown (“in 12d”, “3d overdue”), and a status chip.

Track completion

Click a milestone’s diamond to mark it complete; click again to reopen it. Color tells the story at a glance: completed milestones turn green, upcoming ones are blue, and anything past its due date and still open turns red. Chips above the views count Completed, Upcoming, and Overdue, and completed rows record the date they were finished.

In List view, hover a row for the pencil and trash icons to edit the title and date or delete the milestone.

Milestones on the Gantt chart

Tasks have a Mark as milestone checkbox in the task form. A task marked this way renders on the Gantt tab as a diamond marker at its date instead of a duration bar, which is how key dates stand out on the timeline among regular task bars. This is also how milestones imported from Microsoft Project files arrive.

Note

Milestone entries and milestone-flagged tasks are two sides of the same idea. Entries on the Milestones tab are lightweight date markers; a milestone-flagged task is a real task (assignee, comments, status) that additionally shows as a diamond on the Gantt.

When a project has no milestone entries of its own, the Milestones tab automatically lists the project’s milestone-flagged tasks instead, labeled from task. These derived rows are read-only here: open the underlying task to change its title, date, or completion.

See milestones in context

The project Overview tab includes a Milestones panel with the next few milestones and a View all link to the full tab, so the key dates stay visible without switching views. For the task side of the workflow, see working with tasks.

FAQs

Why can’t I edit some milestones on the Milestones tab? Rows labeled from task are derived from tasks that have Mark as milestone ticked. Edit or complete the task itself and the row follows.

Do milestones affect task scheduling? No. A milestone entry is an independent date marker; it does not move tasks or create dependencies. Use task due dates and dependencies for scheduling, and milestones for the headline dates.

Who can manage milestones? By default, project members and above can add, edit, complete, and delete them. Project viewers see them read-only. Admins can adjust this in the organization’s permission matrix.
