A Hostess 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. Hostess 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 Hostess 204 tenders automatically, extracting shipment details and routing them to your TMS or dispatch system for immediate action by your operations team.

Hostess expects EDI 214 Shipment Status Messages at key milestones: pickup (status code X3), in-transit checkpoints (X1), delivery appointment scheduled (X6), arrived at delivery (X1), and delivered (D1). Some Hostess programs also require departure from origin, border crossing for international loads, and out-for-delivery notifications. Each 214 includes a timestamp, location, and the shipment reference number linking it to the original 204 tender. Stacksync generates 214 updates automatically from your GPS tracking or TMS milestone events, keeping Hostess's visibility platform current without manual status entry.

A Hostess EDI 990 is the carrier's response to a 204 Motor Carrier Load Tender. It communicates whether the carrier accepts, rejects, or conditionally accepts the tendered load. The B1 segment contains the response code: A (accepted), D (declined), or other qualifiers for conditional responses. The 990 references the original 204 by shipment ID so Hostess can match the response to the correct load. Stacksync generates 990 responses automatically based on your fleet capacity and lane preferences, ensuring timely tender responses that protect your preferred carrier standing with Hostess.

Carriers respond to a Hostess 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. Hostess 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.

Most Hostess programs expect EDI 214 updates at every significant milestone — typically pickup, each major transit point, and delivery. Some high-priority Hostess lanes require periodic in-transit updates every 4 to 8 hours, regardless of milestone events. The key is that Hostess should never need to call your dispatch for a status check. Stacksync integrates with your ELD or GPS provider and sends 214 updates automatically based on geofence triggers or scheduled intervals, ensuring Hostess has continuous visibility without your dispatch team manually generating status messages.

Hostess typically expects an EDI 990 response within 30 minutes to 2 hours of sending the 204 Load Tender. The exact window depends on Hostess's tender process — some use a waterfall approach where the load is automatically retendered to the next carrier if no 990 is received within the time limit. Slow responses mean lost loads and reduced tender volume over time. Stacksync processes incoming Hostess 204 tenders and generates 990 responses in real time, often within seconds, based on your pre-configured acceptance rules so you never miss a tender deadline.

No. Stacksync handles the entire EDI transport layer. We connect directly to Hostess'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. Hostess 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, Hostess'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 Hostess 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. Real-time monitoring alerts you to issues before they become chargebacks.

When you send a Hostess 990 with a decline code (D), Hostess's system removes you from consideration for that specific load and retenders it to the next carrier in their routing guide. Declining loads is normal and expected — carriers cannot accept every tender. However, consistently declining Hostess tenders may reduce your standing in their carrier ranking and lead to fewer tender opportunities over time. Stacksync tracks your acceptance ratio for Hostess and alerts you when declining too many loads might impact your preferred carrier status.

Missing or late EDI 214 updates can result in Hostess chargebacks, reduced carrier scorecard ratings, and loss of preferred carrier status. Hostess uses 214 data for dock scheduling, inventory planning, and customer notifications — when status updates are missing, it creates operational blind spots. In some Hostess programs, consecutive 214 failures trigger automatic load retendering to backup carriers. Stacksync monitors 214 delivery and alerts your team if a status update fails to transmit, allowing you to resend before Hostess escalates the issue.

Yes, Hostess EDI 204 supports multi-stop shipments through multiple S5 (Stop Off Details) segments. Each stop includes the facility address, stop type (pickup or delivery), scheduled date and time window, and the specific freight being handled at that location. The stops are sequenced to define the route order. Stacksync maps multi-stop Hostess 204 tenders into your TMS routing system, creating individual stop records with proper sequencing so your dispatch team sees the complete route plan without manually parsing the EDI document.

Stacksync connects to your TMS, ELD, or GPS tracking system and automatically generates Hostess 214 messages when shipment events occur. When a driver checks in at pickup, crosses a geofence, or completes delivery, Stacksync captures the event, formats the 214 with the correct status code, location, and timestamp, and transmits it to Hostess's EDI network. The platform handles appointment codes, exception reporting (delays, refused deliveries), and proof-of-delivery confirmation. Your drivers continue using their existing tools while Stacksync handles the EDI compliance layer automatically.

Yes. Stacksync can automatically generate a 990 acceptance response when a Hostess 204 matches your configured criteria — such as approved lanes, equipment type availability, weight limits, and date range. You define the rules once, and Stacksync evaluates each incoming tender against them. Loads that match are accepted automatically with a 990, while loads outside your criteria are either declined or routed to your dispatch team for manual decision. This hybrid approach ensures you capture desirable Hostess loads instantly while maintaining human oversight for edge cases.

Stacksync connects to your TMS or dispatch system and processes incoming Hostess 204 tenders in real time. When a tender arrives, Stacksync extracts the shipment details — origin, destination, commodity, weight, equipment type, and pickup/delivery windows — and creates a load record in your system. Based on your capacity rules and lane preferences, Stacksync can auto-accept loads with a 990 response or route them to your dispatch queue for manual review. The platform tracks tender acceptance rates and response times to help you maintain preferred carrier status with Hostess.

When a Hostess 204 includes multiple stops (S5 segments), Stacksync evaluates the entire route before generating the 990 response — not just the origin and destination. The platform checks capacity for each stop, validates that pickup and delivery windows are feasible given transit times, and confirms equipment compatibility at every location. If all stops meet your criteria, Stacksync sends a 990 acceptance for the full multi-stop load. If any stop presents a conflict, the platform flags it for your dispatcher rather than auto-declining the entire tender.

Yes. The EDI 214 provides an independent record of when pickup and delivery actually occurred, which is essential for auditing freight invoices (EDI 210). If a carrier's 210 invoice claims accessorial charges for detention, the 214 timestamps prove how long the driver waited. If a delivery date on the invoice doesn't match the 214 delivery confirmation, it signals a billing discrepancy. Stacksync cross-references 214 data with 210 invoices automatically, flagging mismatches in dates, locations, and service events for your freight audit review.

Yes. Stacksync integrates with any system that has a database or API — including SAP, Oracle, NetSuite, Microsoft Dynamics, and custom-built ERPs. Data flows bidirectionally between Hostess's EDI network and your system in real time.
