Motor carriers send this transaction set to freight customers and shippers to provide a detailed invoice for transportation services rendered. The document contains freight details, charges, and proof of delivery information organized by shipment components. The B3 segment (Beginning Segment for Carrier’s Invoice) establishes the invoice foundation and carrier information, while the L1 segment (Rate and Charges) itemizes individual line-item charges, and the L3 segment (Total Weight and Charges) provides summary totals. Supporting segments such as S5 (Stop Off Details) enable carriers to document multiple pickup and delivery stops within a single shipment, and L0 (Line Item - Quantity and Weight) captures the physical characteristics of freight for each line item.

Consider a scenario where TransPort Logistics, a regional motor carrier, completes a shipment for Midwest Manufacturing from their Chicago facility to a distribution center in St. Louis with two stops in between. TransPort would generate an IM210 document that begins with carrier and invoice details in the B3 segment, then uses multiple S5 segments to record the intermediate stops with their corresponding dates and times. For each major freight component, an LX loop itemizes the shipment contents, weights, hazardous material designations if applicable, and associated charges through L0 and L1 segments. The document concludes with an L3 segment summarizing total weight and the complete invoice amount due, which Midwest Manufacturing receives to reconcile against their freight payment records and to verify that charges align with the service provided.
