The nice thing about traveling for work is that you can hop in a taxi without worrying about the cost since, after all, you're not picking up the tab. The downside of that privilege is that, about a week or two after that, you'll have to sit down and tediously justify your expenditure to your boss. That's not a problem, however, if your company has signed up with Uber for Business, which sends the bills straight to the firm instead of piling on your own credit card. Until now, however, that service was only available in the US and Canada, with a few trials taking place in the UK and France. As you might have guessed from the headline, today's the day that the company opens up Uber for Business to all of the 45 countries in which it operates. Now all we have to do is work out if we can pretend that our hand slipped and we hit the Uber Lux button by mistake.
