If you only use four, use these. Together they answer the question behind every offer: does this load pay more than it costs? Start with cost per mile to set your floor, then check every offer against it.

From numbers to loads
The tools tell you what a good load looks like for your truck. Finding enough of them, week after week, is the hard part. That's what our dispatch desk does: we search and negotiate against your floor, check every load, and send it to you for a yes or no. The broker sends the rate con straight to you. Our fee is 5% of gross for one truck with authority older than 6 months, only on loads you haul. See pricing, or read our guides.
