I have used this software for many years. It has several strengths.
BUT if you do not belong to MYOB's own network of accountants, you should be very careful for two reasons before buying it. First that the upgrade costs and policies of MYOB are worse than almost any other company or developer. Second that completely on a random basis this software will seek to verify your registration with its website. Apart from being an intrusive, annoying invasion of privacy, I don't know what data about you it sends to MYOB or what it would do if you did not have the internet connection just at time the software wanted to check your licence. Would you loose all your data or continue your work if you can not establish contact with MYOB over a week end or holiday?
New users should purchase at their own risk because more expereinced ones would know about the above situation. There are many accounting products available for small businesses and non-MYOB network affiliated accountants.
