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.

Time Tracking

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

How it works.

Three steps. No setup ceremony. No onboarding calls required.

STEP 01

Set up a project.

Create a client, add a project with a budget. Add tasks for the work ahead. Takes three minutes.

STEP 02

Track time as you work.

Open a task, hit start. Stop when you're done. Zentract logs it against the client and project, billable or not.

STEP 03

Invoice with one click.

Select a billing period. Review grouped line items from real entries. Export. Done.

Free to start.
Scales when you do.

Everything you need to run a small team — no credit card, no 14-day trial cliff. Upgrade when your operation grows.
