You can even choose which currencies you want to use, and QuickBooks Commerce will calculate the prices automatically (based on Google exchange rates or your pre-defined rates). Customers can see the prices in their currency, while your accounting records and intelligence reports will be kept in your base currency. All of this is automatically calculated and converted by QuickBooks Commerce.
For example, if you import coffee from Italy and sell it in Australia, you can set the Buy Price in € EUR, which will be converted into your base currency for approximate costs. Or if you sell to a global market, you can set different prices in different currencies for your varied customers.
As for price levels, you can, for instance, assign a European customer to the Europe Wholesale Price in € EUR while keeping your base currency in USD. Or, you can set default discount rates for specific customers, as well as their payment terms. You can also set price levels for customers buying in bulk.
