Our advantages


The Aval L.L.C. accounting is distinguished by an excellent and experienced team of employed professionals with rich experience. Employee motivation and continuous education is important to us, which contributes to the fact that there is no fluctuation in the work force.

Our business organization

We are a medium-sized accounting, so we can adapt to almost every rational need of micro, small or medium-sized companies or sole traders (Sp). We operate in a way that each company, each client is managed by two of our employees, so that contract work flows without interruptions, regardless of sickness leave, maternity leave or any other absence from work.


With the help of a fast and reliable software app, we can provide you with a constant insight into the status and changes of business events in your company’s general ledger, 24 hours a day, every day of the year, from any location with guaranteed access to the Internet.


Data security has always been paid great attention. We defend our system from external attacks with a dual firewall and a very high-quality antivirus program. In Aval L.L.C., archived backups are generated daily, on three different media sources and four different locations.


We are aware that we are dealing with very sensitive data, therefore we pay special attention to the confidentiality of data and business-related secrets, and consequently, we have adequate, sharp non-disclosure clauses with employees and external contractors.

To be better each day

Reflection on how to further improve and rationalize contractual cooperation is a part of our everyday work process. We try to apply the practice mentioned whenever there is an interest from both contractual parties.
