Investigating Why UPS Next Day Air Appears Cheaper Than Ground

This article explains why UPS Next Day Air (Next Day Air Saver) can sometimes appear cheaper than UPS Ground in rate calculations and lists concrete steps to investigate and resolve the discrepancy.

Summary

  • ShipWise requests rates from carriers by sending shipment data (origin, destination, weight, dimensions and other info); carriers return service rates and the platform selects among returned rates.
  • Factors that can make Next Day Air appear cheaper than Ground include account/profile markups and the raw carrier rates returned by UPS; dimensional data (DIMs) can also affect returned rates.

How rate differences can occur

  • Carrier-provided rates: ShipWise sends address, weight, dimensions and other shipment info to UPS; UPS returns rates for requested services. The platform selects the best rate from those returned.
  • Profile markups: Pricing profiles can apply percent markups per service. Example: a profile with a 25% markup on Next Day Saver and a 40% markup on UPS Ground can make Next Day appear cheaper after markup.
  • Raw carrier rates: Even with no markups applied, the raw rates returned by UPS can sometimes show Next Day Air cheaper than Ground for a given shipment.
  • Dimensions and DIM-weight: If dimensions are missing, rating may not use DIM-weight; whether DIMs are provided can change returned rates.

Investigation steps (use these in order)

  1. Verify profile markups:
    • Check the pricing profile(s) applied to the order and review per-service markups (percentages) for Ground and Next Day services.
  2. Test using a no-markup profile:
    • Rate the same shipment using a test profile with no markups to compare raw returned rates.
  3. Confirm shipment data sent to the carrier:
    • Ensure origin/destination, weight, dimensions (L×W×H), and any other shipment attributes are correctly provided.
  4. Re-run rate requests with dimensions:
    • If previous tests lacked dimensions, include accurate dimensions so DIM-weight is considered by the carrier.
  5. Capture the exact API rate call:
    • Retrieve the API request/response log for the specific rate request to see the raw rates UPS returned.
  6. Contact the carrier if needed:
    • If raw returned UPS rates show Ground higher than Next Day and you cannot explain it from account settings or shipment data, contact UPS to verify why their server returned those rates.

Troubleshooting tips

  • If Next Day is cheaper only after markup, adjust or standardize markups across services in the active pricing profile.
  • If Next Day remains cheaper with a no-markup profile, compare the carrier’s raw rate responses (API logs) and involve UPS support to clarify carrier-side pricing.
  • Ensure dimensions are provided when appropriate; missing DIMs can change whether DIM-weight pricing applies.

Conclusion When Next Day Air appears cheaper than Ground, the difference is driven by the rates UPS returns and by any per-service markups applied in pricing profiles. Use the investigation steps above—check profile markups, test with a no-markup profile, confirm dimensions, capture the API rate response, and contact UPS—to identify and resolve the root cause.
