No single winner

The answer is always 'it depends'. USPS wins under 1lb to Zone 1–4. UPS wins for 5–10lb across all zones. FedEx wins for next-day. DHL wins for international. The trick: route every shipment to the right one, automatically.

What 'rate-shopping' really does

A WMS with real rate-shopping compares all enrolled carriers at the moment of label print, picks the cheapest that hits the promised SLA, and books it. Brands that switch from single-carrier to rate-shopping cut shipping cost 11–18% with zero customer-facing change.
