Your business may be doing well, but it can always do better. One easy way to do so is to invest in language translation. Invest in an accurate, professional translation program like Jarvisen. We break down the barriers of language, so everyone you speak to knows what you're saying and understands your intent too.
With Jarvisen in hand, understanding what the locals are saying (and vice versa) isn't a problem no matter where you go.
That said, there are certain common, basic phrases that you should have at the ready with no assistance. After all, what if your Jarvisen runs out of battery, or you forget it at the hotel?
