Stop demurrage & detention before it drains your budget
Control Tower watches the free-time clock on every container, shows the money at risk today and warns you before charges begin, so every box is picked up and returned while it is still free.
How it saves you money
Built around the one cost in container shipping you can almost always avoid.
Money at risk, right now
One live number across all your containers: the demurrage & detention actually accruing today. No more surprise invoices at month end.
Forecast before it bites
See what each container will cost if your planned pickup and return dates hold, clearly labelled as a forecast, so you act early and bring the number down.
Free-time countdown + alerts
Every container shows exactly how many free days are left and when charges start, ranked by urgency, so you know precisely what needs action and when.
Proof of the savings
Track the charges you avoided by acting in time, the running tally that shows Control Tower paying for itself.

Control Tower FAQ
What is a supply chain control tower?
A control tower is a single place that watches your shipments end to end and tells you what needs attention before it becomes a problem. Panvaya Control Tower focuses on the most avoidable cost in container logistics, demurrage and detention, by tracking the free-time clock on every container, showing the money at risk right now, and warning you in time to act.
How does Panvaya Control Tower help me save on demurrage and detention?
It watches each container's free time at the destination port and alerts you before charges start, so you can arrange customs clearance, trucking and the empty return in time. It also shows your live "money at risk" across all containers and a forecast of what each box will cost if your current pickup and return plan holds, turning surprise invoices into avoidable, planned-for costs.
What is the difference between the actual and forecast cost shown?
Actual is real money already accrued from events that have happened (a container discharged and sitting past free time). Forecast is an estimate of what it will cost if your expected pickup and return dates hold, shown clearly as a forecast so it is never confused with money already owed. Together they tell you what you owe today and what you are heading toward.
Do I need to enter rates for every container?
No. You set your demurrage and detention rate tariffs once in Control Tower settings and they apply to every container automatically. You can still override the rate on an individual container when a carrier or lane has a special tariff.
How is the Control Tower different from the free demurrage calculator?
The free demurrage calculator is a one-off what-if estimate for a single set of dates. The Control Tower runs continuously across all your tracked containers, pulls the dates automatically from live tracking milestones, ranks every box by urgency, and proactively warns you before free time runs out, so you act in time rather than calculating after the fact.
Is Control Tower a paid feature?
Control Tower is part of Panvaya's premium plans. Because it typically prevents far more in demurrage and detention than it costs, it pays for itself quickly. Create an account and choose a plan to switch it on for your containers.
