Automatic Trailer Detention and Demurrage Tracking
Throughout the day, WebRun monitors dwell times in YardView for every trailer in the yard, flags any unit approaching its free-time window, posts an alert to Slack so your team can act, and appends the event to a Google Sheet detention log so you have a full charge history.
How can I track trailer detention and demurrage risk before charges accrue?
WebRun checks dwell times in YardView every 30 minutes, flags any trailer within two hours of its detention free-time limit, and posts an alert to Slack so your yard team can act before fees accrue. Every event is appended to a Google Sheet detention log for dispute reference.
- At-risk trailers are flagged two hours before detention starts, not after
- Your team gets a Slack alert before each business hour window closes
- A Google Sheet log gives you timestamped evidence for every detention dispute

Questions, answered
How far in advance does it warn about detention?
It flags trailers within two hours of their free-time limit so your team has a real window to act, move the trailer, or contact the carrier before fees start.
Does it automatically notify the carrier?
No. Carrier communications are not sent automatically. WebRun posts the alert internally to Slack so your team can decide how to respond and contact the carrier directly.
Can I use the sheet to dispute detention invoices later?
Yes. The Google Sheet logs arrival times, dwell durations, and departure times for every flagged trailer, giving you a timestamped record you can reference when reviewing or disputing a detention invoice.
