Enable Shipping Fee Rule:

1. Go to "Product Management" > "Product Category Settings", and add a product category named "Shipping Fee". Other fields can use default values, as shown in Figure 1.

2. Then go to the "Product List" and add a new product with the "Product Code" set to "Shipping Fee". It is recommended that the "Product Name" be the same as the "Product Code", and the "Product Category" should use the one created in the previous step. Other fields can use default values, as shown in Figure 2.

After completing the above steps, the B2B shipping fee rule function will be enabled.

Figure 1:

Figure 2:

2. Add a new shipping fee rule, as shown in the figure below:

Enter the "Order Amount Threshold", "Minimum Shipping Fee for Amounts Below Threshold", "Shipping Fee Percentage for Amounts Exceeding Threshold", and "Applicable Region". After completing the edits, save to successfully add a new shipping fee rule.

Matters need attention:
After saving, the list items will be sorted automatically according to  the order amount limit from small to large.
“Order amount"refers to the total amount of all setled goods in the same sales order,exluding "Freight", "dicount" and "deduction" and other expenses.
For customers in the same region who meet two or more "order amount limit" conditions at the same time, the "basic matching principle" (see below) will be used to match.
If you need to exempt customers in a certain region from freight, please add a rule item with zero values such as "order amount limit", "minimum freight for the part not exceeding the limit" and "Freight percentage for the part exceeding the limit" Only when this rule exists and is enabled can custmers in this region use self extracting, and the priority of this rule item will be lower than other rule items requiring additional freight.
If you need to avoid freight for a single customer, please open the"open network client",set in the"customer data",and select the "B2B
mall allows self delivery" option for customers.

Parameter	Function
Basic matching principle	only the most consistent rule items are matched,and those with a large value of "order amount limit" will be preferentially matched. If the "limit" is the same,the "lowest freight of the part not exceeding the limit" will be used. If the "lowest freight" is the same,the "Freight percentage of the part exceeding the limit" will be used again.
Freight calculation formula symbols	Frt=Freight,Amt=The order amount,Lmt=Order amount limit,Fxd=Minimum freight for the part not exceeding the limit,Rt=Freight rate of overrun part.
Formula when the order amount is less than or equal to the limit value	Frt =Fxd
Formula when the order amount is greater than the limit value	Frt = Fxd + ( Amt - Lmt ) × Rt
