Control over ETA and transport communication: without disruptions in operations

In road transport, one question always takes precedence: when will my delivery arrive?
For planners, the answer is rarely set in stone. A route gets delayed. A loading time runs over. A driver gets stuck in traffic. The delivery location turns out to open later than expected. Reality is constantly changing.
Your customer expects clarity. No noise. No five updates per hour. Only reliable information, at the right time. That is precisely where the challenge lies.
Why ETA communication often goes wrong
Many transport organizations recognize this scenario: there’s a minor delay, a new ETA is generated, and the customer receives a notification. Then another minor change occurs, and the customer receives another update. The result is that the customer is inundated with information instead of clarity.
Or, conversely:
- Updates are shared too late
- The customer has to call you themselves
- Customer trust in your organization declines
Communicating too much is just as harmful as communicating too little. So the question isn’t whether you communicate, but when something is truly relevant to share.
From ad-hoc updates to structured steps
Events along the way are unpredictable, but milestones are fixed actions in the transport process that you can define. Within Boltrics’ TMS, you can do this in the Trip Planning module, under Event & Milestones. Examples of milestones include:
- Shipment Created: the moment the order is created
- Shipment Released: the moment the order is released
- Shipment Planned: the moment the order is linked to a trip
- Load: the planned, communicated, and executed loading time
- Deliver: the planned, communicated, and executed unloading time
- POD Received: the moment the POD is received or uploaded
This creates a clear timeline for each transport order.
A single source of truth at every moment: from planning to execution
For each milestone, you can record different points in time: what is planned, what is communicated, and what actually happens. This gives you continuous insight into discrepancies between the plan and reality -exactly where operational gains can be made.
But the real power lies in shared insight. Not only planners have this insight, but customer service also has real-time visibility into the progress and expected schedule of an order, per event and per milestone. Everyone works with the same information, allowing you to respond faster, proactively inform customers, and improve collaboration across the supply chain.
See below how these time points are organized by milestone within Boltrics’ TMS. This overview shows where deviations have occurred and where you can immediately make adjustments in your operations.

You decide: when does a changed ETA require communication?
Not every change in the schedule automatically triggers a new communication. Boltrics TMS uses smart update logic for this.
You can define the triggers for this update logic yourself. For example: How significant a deviation must be before you respond, within what time window updates make sense, and whether an update is sent immediately or scheduled.
Automatic follow-up via event triggers
As soon as a change is relevant, the system takes over. Whenever the schedule changes, the system automatically determines whether this is relevant. If it is relevant, it then acts automatically. An example:
A delivery is scheduled for 10:00. Because the driver is stuck in traffic, the ETA shifts to 10:04. You previously specified in your setup that a delay of an activity within a 30-minute timeframe does not need to be communicated. Therefore, nothing will be communicated to the customer at this point. Later on the route, the driver has to wait before loading can begin. The ETA shifts to 10:31: now a notification is sent.
Why? Because only that second change impacts the customer. This is precisely the difference between collecting data and sharing relevant information.
Below you’ll find examples of event triggers in Boltrics’ TMS.


From Execution to Insight
Because all milestones and events are recorded, you automatically build a dataset that you can use to guide operations and provide accountability – not only internally, but especially to your customers.
At a glance, you can see where planning and execution diverge, where delays occur, and how performance is developing at the vehicle, customer, or order type level. These insights form the basis for targeted reports: essential in a market where delivery performance is increasingly being contractually defined.
This allows you to demonstrate whether SLAs are being met, make targeted adjustments where necessary, and prevent disputes later on. See in the image below how these insights come together as concrete management information within Boltrics’ TMS.
This way, you can use Events & Milestones not only to record what is happening, but also to gain control over your performance and to report that performance transparently and substantiated to your customer.

Control over transportation starts with the choices you make
Transportation remains dynamic. That won’t change. What does change, however, is how you manage it.
By structuring key milestones for each order, intelligently filtering updates, and automating communication, you bring calm to your operations and clarity to your customers.
