First, we will identify the companies which provide translation services. We will start off with the information per NACE code and public domain information.

For the net sales revenues, we will use data from the last fiscal year for each company i.e. 2019. The data are provided by our survey partner Company Guru. Each company will take part as an individual entity, and their results will not be added, regardless of their correlation.

Our aim is to present only the data that show a company's revenue generated from translation services. Where a company advertises publicly that it provides other services as well, the data collected will show the amount of their total revenue. It is impossible to separate the revenue by activities only on the basis of annual reports, press publications or other documents which we have as sources. Therefore we will try to contact the representatives of these companies and request proof of net sales only from "Translation Services” (7430) as their economic activity. If they choose not to cooperate, we will not be able to rank these companies accurately and this may possibly distort the ranking. In order to avoid such a subjective approach, companies whose turnover is over BGN 100,000 but whose revenue from translation services can't be determined will be listed separately because they deserve to be addressed.

We do not tolerate unfair competition, which is why informal revenue will not be taken into account.
