Where this helps

When the preferred carrier declines, a broker often copies the same lane, dates, equipment, and reference numbers into multiple systems. The result is a disconnected set of quotes with little context about past performance.


What Rectangle connects

Rectangle exposes the load requirements and previous carrier performance. An assistant can pass that context to an authorized capacity marketplace, rate service, or carrier directory through their available tools. Responses are normalized to the same equipment, pickup window, and all-in cost basis; unanswered requests remain pending.

From answer to action

The broker sees known carriers and new candidates together, with quote timestamps and unresolved requirements. The selected carrier still needs current compliance and capacity confirmation. The assistant prepares the tender with the source load ID so a reviewed action can update the TMS without duplicate entry.
