I am new to Shopify, and we have a Shopify site for our B-C customers, a customer from Canada wants to place an order and cannot? How can we enable the customer to enter his order that is to be shipped to Canada from our US location?
If you go to Settings > Shipping & Delivery then click Manage rates towards the top. On the next page, you'll need to click "Create shipping zone" and choose Canada. You can then select the different shipping methods to Canada, and once it's all set up Canadian customers can place orders.
