If your business serves customers in multiple regions, you will want to set up specific shipping and tax settings for the regions you serve.
Click on your Business name in the top right corner of your Dashboard and select "Business Settings" from the drop down list.
Indicate the default tax percentage for your region and click save. If you are unsure of the tax rates that apply in your region, please consult your local tax regulations. You can also add tax rates for the various regions you serve for easy selection when creating an invoice for international customers.
Specify the shipping costs to send physical goods to the various regions you serve. When you are creating an invoice for a customer, you will be able to select the shipping cost to be charged to the customer based on these pre-set amounts.
You can remove a tax or shipping rate by selecting the red X next to the item you wish to remove.
