I like that it can be used for both VAT purposes as well as Income Tax purpose (VAT is included).
It also has an option where you could create your own rules which are not available with other accounting softwares. The UI needs some improvement but this software works great when compared against others out there! There's nothing much about portolans emvem tool that i dislike at all so far. We use their services mainly because they offer better rates than our competitors do by quite a bit while still providing good service quality.
