Before you start #
Availability and permissions
- The website owner and an enabled store. Calculated rates and labels require configured shipping capabilities.
Have these ready
- Know your shipping origin, return arrangements, empty-package weights and usable box dimensions.
What to do #
- Open Store → Settings & connections. Choose Change measurement units if you prefer grams/millimeters or ounces/inches.
- Choose Edit shipping, tax & policies. In Where orders ship from, enter the single contiguous U.S. origin and order contact details.
- In Approved packages, enter the package name, dimensions, tare (empty package weight) and maximum weight. Measure a real package; do not choose a box using total weight alone.
- In Delivery options, define a stable option ID, customer-facing name and Flat rate, Free shipping or Carrier calculated type. Fields labeled cents use whole USD cents: 500 means $5.00.
- Review allowed Carrier:Service codes and any free-shipping threshold. Check product/variant dimensions, weight and Must ship alone flags.
- Save and test an authorized demonstration checkout for each supported delivery option. Review Customer policies so shoppers know the actual terms.
What to know #
Launch scope is ordinary parcel goods to contiguous U.S. street addresses, one origin, no local pickup, backorders or partial shipments.
The shopper’s shipping charge is not the actual postage expense. Unsupported parcels and failed rate requests must be resolved, not treated as free shipping.
What success looks like #
Supported carts receive the intended shipping choices; unsupported packages and addresses receive a clear explanation.
If something goes wrong #
- No package fits? Correct dimensions or choose another supported package; do not falsify product weight to force a rate.
