Shipping Automation: Compare Rates Across 20+ Carriers in Seconds

The cheapest carrier today isn't the cheapest tomorrow. UPS surcharges spike in peak season. FedEx adds dim-weight rules. USPS Priority changes zone rates twice a year. Manually rate-shopping per order is a full-time job — and humans make wrong calls about 30% of the time.

How rate-shopping should work

For every order, the system should:

  • Pull live rates from every carrier you have an account with
  • Apply your real negotiated rates (not retail)
  • Factor in delivery deadline, weight, dimensions, residential vs commercial, signature requirements
  • Pick the cheapest carrier that meets the SLA — and print the label automatically

What Kasernet does

AutoOMS rate-shops across 20+ carriers in real-time: UPS, FedEx, USPS, DHL, plus regional carriers (LSO, OnTrac, Speedee, Lasership, etc.). Each shop returns in under 800 ms. Your label prints via AirPrinter the moment AutoOMS picks a winner.

One customer saved 18% on shipping spend in month one — without changing carrier contracts, just by stopping the manual "we always use UPS Ground" reflex.
