Sorry I forgot to reply.
A few exchanges in Canada have that feature (bill payment) - such as Bull Bitcoin & Bitcoin Well.

They may only work for Canada + US, but I'm not sure.

It's really smooth, you just add your payee like in any banking app: can be a credit card, electricity bill, etc. then you say how much you want to pay and get a BTC invoice. Pay it with BTC and they pay your bills for that amount in Fiat.

It's a nice alternative way to try living a bit more on a Bitcoin standard, but also a nice way to "sell BTC". Rather than selling for Fiat, withdrawing to bank, paying bill, you just so it in one step.
