USA customer, how to record in QuickBooks?

Hi, 

So we invoice US customers for consulting. They pay us US dollars and we paid our invoices. This money goes to our US chequing account ( as an income/sales income). Then we have money out from a US chequing account to a third exchange currency party to get a better exchange. Then we get money into our CAD chequing ACCOUNT from the exchange we made with a third party ( not sure if record this as a sales income because we already did this on our US chequing account) 

So my questions are how do l record each of this money coming in and out so everything matches in Quickbooks online? 

Thank you
