Start a trial or upgrade when a feature is locked (Gantt, measure, shared todo, extra projects).
Locked features
Locked tabs and buttons show an upgrade prompt. Typical locks include Gantt (Free), PDF measure and export, shared todos, team calendar, and extra projects beyond the Free cap.
Pro trial
Eligible workspaces can start a Pro trial from Billing or from an upgrade prompt. Use the trial to test Gantt, export, and sharing before you pay.
Upgrade
- Open Billing / Plan & Pricing, choose Pro, Team, or talk to us for Enterprise.
- Confirm seats and monthly vs annual, then complete checkout.
- Team plans may require creating a team workspace first if you are still on a personal Free/Pro space.
After upgrade
Locked icons disappear after the plan is active. Refresh the page if a tab still looks locked.
