What is a Hub Group \ Unyson EDI 990 Response to a Load Tender?
A Hub Group \ Unyson 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.

How quickly must a Hub Group \ Unyson EDI 990 be sent after receiving a 204?
Hub Group \ Unyson typically expects an EDI 990 response within 30 minutes to 2 hours of sending the 204 Load Tender. The exact window depends on Hub Group \ Unyson'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 Hub Group \ Unyson 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.

What happens if I decline a Hub Group \ Unyson EDI 204 with a 990 rejection?
When you send a Hub Group \ Unyson 990 with a decline code (D), Hub Group \ Unyson'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 Hub Group \ Unyson tenders may reduce your standing in their carrier ranking and lead to fewer tender opportunities over time. Stacksync tracks your acceptance ratio for Hub Group \ Unyson and alerts you when declining too many loads might impact your preferred carrier status.

Can Stacksync auto-accept Hub Group \ Unyson EDI 204 tenders with a 990?
Yes. Stacksync can automatically generate a 990 acceptance response when a Hub Group \ Unyson 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 Hub Group \ Unyson loads instantly while maintaining human oversight for edge cases.

How does Stacksync handle Hub Group \ Unyson EDI 990 for multi-stop loads?
When a Hub Group \ Unyson 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.
