I have multicurrency enabled and have created a new Supplier with the currency set to USD. I then go to Receipts, where my client has uploaded their invoice, and click on Review. At the top, I change the Document Type to Bill and select the new foreign currency supplier from the Payee list. I complete the remaining fields, with the Account/Category set to the relevant expense (not Creditors). The amount boxes do not specify any currency, which suggests that QuickBooks will apply the relevant currency based on the supplier chosen, however when I then click Create Bill I get a warning which states: The transaction needs to be in the same currency as the A/R and A/P accounts you use.
