⚙️Settings for Shipping Rate
Configure global behavior for how shipping rates are selected and calculated when multiple rules or mixed carts are involved.
These settings apply to all Shipping Rate rules in your store. Open them from B2B pricing › Shipping Rate, then click Settings in the page header. Change an option and click Save in the save bar. A How it works preview next to the options shows how the current choice plays out.

The system uses the highest applicable shipping rate
Choose what the rate is based on
Choose how the shipping fee is calculated when a rule only applies to certain products in the cart:
Entire Order
The shipping rate is calculated based on the subtotal, total quantity, or total weight of all products in the cart — including products that are not covered by the shipping rule.
Example: You create a shipping rule for Product A (Product B has no shipping rule).
5–15 items
20%
16–30 items
$10 flat rate
Scenario 1
3 × Product A = $30
7 × Product B = $35
Total items: 10 → falls in 5–15 range
Order subtotal: $65
Shipping: 20% × $65 = $13
Scenario 2
12 × Product A = $120
8 × Product B = $40
Total items: 20 → falls in 16–30 range
Order subtotal: $160
Shipping: $10 flat rate
This logic applies equally to Amount Range and Weight Range, not just Quantity Range.
Applied Products Only
The shipping rate is calculated based on the subtotal, total quantity, or total weight of only the products that the shipping rule applies to. Other products in the cart are ignored for shipping calculations.
Example: You create a shipping rule for Product A (Product B has no shipping rule).
5–15 items
20%
16–30 items
$10 flat rate
Scenario 1
3 × Product A = $30
7 × Product B = $35
Total items: 10, Applied items: 3 → falls in 5–15 range
Applied subtotal: $30
Shipping: 20% × $30 = $6
Scenario 2
18 × Product A = $180
2 × Product B = $10
Total items: 20, Applied items: 18 → falls in 16–30 range
Shipping: $10 flat rate
This logic applies equally to Amount Range and Weight Range, not just Quantity Range.
