Inventory - CDN and USD


I have an inventory item in CDN (base currency) and would like to sell to a US customer in USD. Can I use the same inventory item or do i have to set up a new item with USD costing?

as i get an error message as follows: "The Selling price for this item is not in the same currency as the customer. Please ensure a selling price in the currency of the customer exists before proceeding"

Thank you
