Know when you'll really finish.
Pertify turns three honest estimates per task into a finish date you can defend, and shows you exactly which tasks can't slip.
One guess per task is how projects slip.
Most tools ask how long a task will take and treat your answer as fact. But every task has a best case, a likely case and a bad day. Pertify plans for all three, so the date you share is one you can keep.
See what matters.
The critical path lights up automatically. You'll know which tasks drive the finish date and how much slack the rest have.
Run it together.
Invite your team, give contributors a focused view of their own work, and share a client view that keeps your rates private.
One plan. Three ways to see it.
Every view stays in sync. Edit anywhere and the whole schedule updates.
The network behind your schedule, with every dependency and the critical path in plain sight.
From a cleared lot to a weather-tight garage.
See how one owner-builder planned permits, crews, inspections and 56 activities in Pertify, and kept a 31-task critical path on track to finish a day early.
