Detention tracking for small fleets

Detention time on the record, from your drivers' phones

Draw a geofence around each shipper and receiver. The driver's phone stamps arrival and departure without a check call. When a truck passes your free time, SpatialFlow emails your billing desk the dwell time and posts to dispatch.

SpatialFlow live map on the Dark basemap with Riverside DC selected: the device list shows TRK-07 Active, In geofence for 2h, and the truck's marker inside the Riverside DC geofence.
The Detention report for Riverside DC: $336.25 owed at $75.00 an hour over 120 minutes of free time, 4h 29m over free time across 8 stops, 1 still on site.

How it works

  1. Draw a geofence around each dock you deliver to.
  2. Drivers start their shift in the free SpatialFlow app on their own phones. No hardware, no check calls.
  3. When a truck passes free time, your rule emails billing and posts to #dispatch. The Detention report prices every stop and exports CSV.

What it proves

GPS timestamps from the driver's phone back up a detention claim. Your rate confirmation and signed BOL still decide what gets paid.

The American Transportation Research Institute found that 94.5 percent of carriers charge detention, but they end up paid for fewer than half of their detention incidents. ATRI, September 2024

Questions crews ask first

Does it work with our ELD?

Not directly. SpatialFlow uses the driver's phone, or any device or system that can post locations to the API.

Our ELD already logs arrival times. What does this add?

Action when free time runs out. When a driver's phone passes free time at a geofence, a rule can email billing, post to Slack or Teams, text the dispatcher through your Twilio account, or call a webhook into your TMS. The Detention report does the rate math and exports CSV.

Will a broker accept it?

It gives you timestamped GPS evidence of arrival and departure and does the detention math. That supports a claim; your rate confirmation and BOL still decide what gets paid.
