What is a FourKites EDI 204 Motor Carrier Load Tender?
A FourKites 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. FourKites 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 FourKites 204 tenders automatically, extracting shipment details and routing them to your TMS or dispatch system for immediate action by your operations team.

What is a FourKites EDI 990 Response to a Load Tender?
A FourKites 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 FourKites 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 FourKites.

How quickly must a FourKites EDI 990 be sent after receiving a 204?
FourKites typically expects an EDI 990 response within 30 minutes to 2 hours of sending the 204 Load Tender. The exact window depends on FourKites'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 FourKites 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.
Do I need an existing VAN or AS2 connection to trade with FourKites?
No. Stacksync handles the entire EDI transport layer. We connect directly to FourKites's trading partner network through our certified connections. You don't need to manage a separate VAN subscription, AS2 certificates, or SFTP configurations.
How do carriers respond to a FourKites EDI 204 Load Tender?
Carriers respond to a FourKites 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. FourKites 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.

What is a SCAC code and why does FourKites require it for EDI 204?
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. FourKites 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, FourKites'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 FourKites transactions.
How does Stacksync help with FourKites compliance?
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.
What happens if I decline a FourKites EDI 204 with a 990 rejection?
When you send a FourKites 990 with a decline code (D), FourKites'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 FourKites tenders may reduce your standing in their carrier ranking and lead to fewer tender opportunities over time. Stacksync tracks your acceptance ratio for FourKites and alerts you when declining too many loads might impact your preferred carrier status.

Can Stacksync auto-accept FourKites EDI 204 tenders with a 990?
Yes. Stacksync can automatically generate a 990 acceptance response when a FourKites 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 FourKites loads instantly while maintaining human oversight for edge cases.
Can FourKites EDI 204 handle multi-stop shipments?
Yes, FourKites 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 FourKites 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.
What EDI document types does Stacksync support for FourKites?
Stacksync supports all EDI document types required by FourKites — including Purchase Orders (850), Invoices (810), ASNs (856), PO Acknowledgments (855), and more. Our platform handles the full lifecycle from order to payment automatically.

How does Stacksync handle FourKites EDI 990 for multi-stop loads?
When a FourKites 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.
How does Stacksync automate FourKites EDI 204 load tender processing?
Stacksync connects to your TMS or dispatch system and processes incoming FourKites 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 FourKites.
Can I connect FourKites EDI to my existing ERP or WMS?
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 FourKites's EDI network and your system in real time.
