The real cost of disconnected tools
01
Time logged late is time not invoiced.
Details fade. Entries disappear. By Friday, no one remembers Tuesday's four-hour deep-work session.
02
Scope creeps before you can react.
You hit 80% of budget with 40% of work left. The signal came too late to have a real conversation.
03
Billing is a monthly reconstruction.
You spend hours piecing together what happened. Then write off the hours that don't have receipts.
Every task
is a timer.
One click starts tracking. Zentract ties the entry to the task, project, and client automatically. No separate app. No retroactive guessing.
- ✓One-click timers on any task
- ✓Billable vs non-billable on every entry
- ✓Log from web or iOS & Android
- ✓Only one timer runs at a time
