Reliable accounting for companies of all sizes and industries. Professional support you can count on!
Professionalism, responsiveness, accuracy, and reliability are essential in an accounting service. Proevent excels in all these qualities; furthermore, they have exceptional employees with whom we have built a true partnership.
The best accounting service. A friendly and professional approach to the client. They truly master their work. If you want a good accounting service for your company, Proevent is by far the best choice.

Director, Retrodesign d.o.o.,
PROEVENT has proven to be a very flexible and highly responsive accounting service. They are professional and diligent in their work, and their team includes various experts, so they have an answer to every one of my questions.
Cooperation with them is easy, allowing us to devote more time to our core business.
When opening a company (in my case, a d.o.o.), I visited quite a few accounting firms. I decided on Proevent d.o.o. and now, after 5 years, I know I made the right choice. I received and still have a favorable ratio between the services received and the price.
It means a lot to me that they operate paperlessly, so I can send business documentation via email and not waste precious time traveling from Trbovlje to Ljubljana. If necessary, I also call them and get quick answers to my questions.
If you, like me, want friendly interlocutors, fast responsiveness, and to be informed monthly about your business, I truly highly recommend them.

The Sailing Federation of Slovenia is a non-governmental organization in the public interest that brings together all Slovenian sailing clubs and takes care of the development of Slovenian national sailing teams, all with a very small office team. That is why it is of utmost importance for us that external partners are top experts in their field who can provide all the necessary support for our complex challenges. In Proevent, we found competence and knowledge, responsiveness and accessibility, and along with always good, correct, and timely advice, a friendly smile.
