CS-Cart and Multi-Vendor need the address of the store and the address of the customer to calculate shipping costs. A customer can enter the address when placing an order or creating the account.
Default Customer Address
The Settings → General page allows you to specify the Default location, in other words, the default customer address. It will be used for testing the rate calculation of real-time shipping methods in the admin panel.

Company Address
The Settings → Company page allows you to specify the sender address (the address of your store and warehouse).
If you have multiple warehouses or suppliers, you can use the functionality of the “Suppliers” add-on.
