Shipping and carrier services

Flat shipping, free shipping threshold, live or estimated rates, UPS, USPS, FedEx, expanded services, and freight add-on planning.

Shipping choices

Flat shipping is always available for physical carts and uses the value from Store Settings.
The free shipping threshold can make flat shipping zero when the cart subtotal reaches the configured amount.
Digital-only carts skip shipping and use digital delivery automatically.

UPS, USPS, and FedEx can be enabled separately.
UPS supports expanded checkout choices such as Ground, 3 Day Select, 2nd Day Air, Next Day Air, and Next Day Air Early when the live API returns them.
USPS supports Ground Advantage, Priority Mail, Priority Mail Express when available, Media Mail, and Library Mail. Media Mail and Library Mail should only be offered for eligible products.
FedEx supports Ground, Express Saver, 2 Day, 2 Day AM, and Standard Overnight when the live API returns them.
Each carrier has its own credential fields and environment setting. Use sandbox or test mode when available before switching to production.
If credentials are missing or a carrier call fails, SmithShop uses estimated rates so checkout can still be tested.

Use the service checkboxes to decide which methods customers can choose, such as ground only or ground plus 2nd day.
Only selected services are shown at checkout for that carrier.
Product weight and dimensions affect estimated and live rates, so physical products should have realistic package values.

Freight shipping belongs in Admin > Add-ons so normal parcel shipping stays simple.
Freight providers can require heavier product data such as freight class, pallet handling, weight, dimensions, residential delivery, and liftgate needs.
Use manual freight quote as the safe fallback until a freight provider integration has been tested with real credentials.
