Lets say i buy an Xbox from Microsoft for x bitcoins. On the date of buying the x bitcoins correspond to z dollars. After few hours, the bitcoin cost reduced from x to y. (The price is volatile right) How Microsoft will handle this situation? They are ready to take the risk? Or they exchange to dollars or any currency as soon as I buy the product in bitcoin?
Many companies will instantly convert bitcoins to fiat upon receiving. This is done by the payment gateways themselves like Bitpay, coinify.

However, these days you see several website keeping the bitcoins without converting them. You can use payment gateways like blockonomics, blockchain.info, coinsimple etc. This is due to several reasons:


Extra fee in converting
Regulations/KYC in accepting fiat
Bitcoins are scarce  
Adoption has increased. Employees are taking wages in BTC, and business can buy stuff like airline tickets and other required goods directly using bitcoins
