For agencies that bill time
Make every billable hour show up
on the invoice.
Zentract keeps tasks, time, and budgets in one place so you catch missed time and overages before they turn into write-offs.
No credit card required.
Time-to-invoice check
Signals
- Timers always start on a task.
- Only one timer runs at a time.
- Billable vs non-billable is explicit.
One example
Select a task → start the timer → stop it with a short note. That entry is already tied to the client and project.
Outcome
Turn a billing period into grouped line items for invoicing.
Trusted by agencies and consultancies
Revenue leakage is usually quiet.
It happens when work moves forward, but time and billing fall behind.
Time gets logged late.
Details fade, entries get missed, and invoices don’t match the work.
Scope drifts without a signal.
Projects creep past expectations before anyone can course-correct.
Billing becomes a cleanup task.
You spend the end of the month reconstructing what happened.
Three levers that protect margin.
Zentract connects delivery, time, and billing so you can see drift early and invoice with confidence.
