Which tool is used to track starting and ending contacts with a carrier?

The tool used to track starting and ending contacts with a carrier is aptly represented by the term "Call Checks." This tool allows users to log and monitor communications related to carrier interactions, ensuring that all pertinent details regarding the initiation and conclusion of business dealings are documented. Maintaining an accurate record of these interactions is crucial for fostering good relationships with carriers, preventing miscommunication, and providing transparency throughout the shipping process.

While Load History provides insights into shipments and their statuses, it does not specifically focus on the tracking of communications with carriers. Similarly, Delivery Notes pertain to the documentation of delivery specifics rather than the communication timeline with carriers. Rate Sheets, on the other hand, typically outline pricing and tariffs and do not encompass the tracking of contact history. Thus, Call Checks is the most appropriate tool for the purpose of monitoring contacts with carriers, making it the correct choice.
