A Miller Truck Lines EDI 204 is an electronic request from a shipper or broker to a carrier to transport a load. It contains the pickup and delivery locations, commodity descriptions, weight, equipment requirements, and requested dates. Miller Truck Lines sends 204s to carriers in their network to tender freight for acceptance. The carrier responds with a 990 (Response to a Load Tender) to accept or decline. Stacksync processes Miller Truck Lines 204 tenders automatically, extracting shipment details and routing them to your TMS or dispatch system for immediate action by your operations team.

Carriers respond to a Miller Truck Lines 204 Load Tender with an EDI 990 (Response to a Load Tender). The 990 includes an acceptance or rejection code — carriers can accept the load as tendered, accept with modifications, or decline. Miller Truck Lines typically expects a 990 response within a specific timeframe (often 30 minutes to 2 hours). Failure to respond may result in the load being retendered to another carrier. Stacksync automates 990 responses based on your fleet capacity and dispatch rules, ensuring timely acceptance of profitable loads and automatic declination when capacity is full.

No. Stacksync handles the entire EDI transport layer. We connect directly to Miller Truck Lines's trading partner network through our certified connections. You don't need to manage a separate VAN subscription, AS2 certificates, or SFTP configurations.

A SCAC (Standard Carrier Alpha Code) is a unique 2-to-4 letter identifier assigned by the National Motor Freight Traffic Association (NMFTA) to transportation carriers. Miller Truck Lines uses SCAC codes in EDI 204 tenders to identify the carrier being tendered the load, and carriers must include their SCAC in the 990 response and subsequent status updates (214). Without a valid SCAC, Miller Truck Lines's system cannot route the tender or track the shipment. Stacksync stores your SCAC code and automatically includes it in all outbound EDI documents, ensuring proper carrier identification across all Miller Truck Lines transactions.

Stacksync improves compliance scores by eliminating manual processing delays. Purchase Orders sync to your system in real time, ASNs are generated automatically when you ship, and invoices are validated with three-way matching before submission.
