PTY registration may not necessarily be mandatory, but there are certain benefits that can seriously convince you about it. Basically, registering a business is one of the first requirements when interested in conducting business with a governmental agency, institution or corporation. The government will never risk running out of supplies or wasting valuable time just because you choose to disappear one day. Instead, aside from the extra credibility, the registration will also motivate you to push your limits some more. Plus, you are supposed to respect particular rules too, which is a good enough guarantee for any kind of governmental institution.
