It's the first I'm aware of. Doesn't mean some haven't been doing it unannounced, though.
Have you got a policy for how you account for big exchange rate swings? The expectation is that the swings will lessen with time, but we're definitely still in ski-jump slope territory now in 2013.
To be honest we're not expecting a huge amount of Bitcoin-paid business as we don't handle personal effects, but it's our intention to hold funds in Bitcoin rather than exchange for fiat. If trade volumes are significant we'll need a different strategy since none of our suppliers currently accept Bitcoin. In that case we'll probably use Bitpay.
That's an interesting strategy to start with. I hope that in the event of picking up more BTC trade than you're expecting, you'll consider persuading suppliers to accept too. Who knows what the economic landscape will look like to everyone by the time that happens...
There are hints that Cyprus style bail-ins may happen across the OECD nations. Your little Bitcoin hedge will see you well in those circumstances. A (formerly) Cyprus based businessman is here on Bitcointalk frequently, his business account had 700,000 euros frozen from use. Then one day, the frozen funds weren't even indicated in his account anymore, as if the money had never existed! That kin of thing might start changing the minds of people you do business with in your industry's ecosystem.
