This is a good summary. I just wanted to add that it can be easier even than that. I look after this sort of thing sometimes. I would normally have USD, GBP, EUR accounts at my local bank. Any money from abroad can be wired directly in to those accounts. If I want to trade between currencies I can then do it through my bank, which can cost me '20 pips', which means on a GBPUSD deal I pay 0.0020 over spot atm (trading around $4m a year. YMMV). This is at the click of a button, or a phone call. But I can do other convenient things through the same platform to hedge risk. I can hedge, for instance I can agree to buy sterling sell dollars at $100k a month for the next year at agreed rates to protect a contract from fx risk. I can swap currency with the bank for a few days for even more trivial fees, swaps are useful when you have too much of the one currency this week, but need it back to pay a supplier next week, or indeed if your forward contracts are arriving and you are not ready for them yet.

In summary I agree, it is not hard in NA or EMEA to send intentional funds
