For the conventional user, they will more than likely look for free translation services and software on the internet for every day translations, mostly looking up a word and translating it into another language. For this purpose, those free translation programs work very well, however once you get into longer documents and even mere sentences, the level of quality and accuracy dramatically spirals downwards in many cases.

If you don't agree with me, then try taking one well-written paragraph in any language you prefer, preferably one that you are a native speaker/writer in, and convert it into another language that you also have fluency in. You more likely than not will find that the class of the translation is not only subpar, but even a toddler has a better chance of writing something better.

For tailored and limited uses, it's perfectly fine to use these types of avenues for your translation needs, but when you start progressing up to the level where you need to incorporate communications to a worldwide audience for business purposes, hiring a quality translation services team is highly fundamental.
