Read lane history

Where this helps

A broker needs a dry van for a familiar lane. The cheapest carrier on the last load is not necessarily the best choice, and the team’s history is scattered across tenders, tracking events, claims, and invoices.


What Rectangle connects

Rectangle makes the TMS history available to an MCP-compatible assistant. It matches the lane and equipment, compares paid all-in costs per mile, and shows on-time performance alongside sample size. Canceled loads and missing delivery events are separated so the ranking does not reward incomplete records.

OpenAICompare service and price
Rank carriers with at least 10 loads and 95% on-time delivery.

Prairie Freight and Northline Transport are worth calling first. Both clear the 95% on-time threshold with at least 10 completed loads.

CarrierLoadsOn timeAll-in cost
Prairie Freight2495.8%$2.14/mi
Northline Transport18100%$2.21/mi
Roadstead1283.3%$2.05/mi

Roadstead is cheaper, but falls below your service threshold. Prairie has the lowest qualifying historical cost; Northline has the strongest observed service.


From answer to action

Carrier sales gets a ranked call list with the loads behind every metric. A connected carrier directory can supply current contacts; an authorized capacity service can add today’s availability. Historical pricing supports the conversation, while a fresh quote establishes the buy rate.
