Client has a U.S bill from his client with many different line items and prices. Multicurrency is turned on. Client is 2X recorded in QB, 1 as US, and another as CAD. The bill was partially paid in CAD with a CAD credit card. If I use the Client CAD for the bill, do I have to calculate each line item in CAD at the CC rate for the first payment? Then how do I calculate the bill difference for the subsequent payments?
