I have set up multicurrency and added a USD-based customer.  When setting up the service fees for that customer, I can only enter the fee in CAD, which will not work because the contract fee is in USD.  QB support suggested setting up a price rule via Products and Services in Sales tab in Account and Settings.  I do not have that as an option.  The only options are Show Product/Service on sales forms, Show SKU column, and Track quantity and price/rate.
