About us


THOMAS Sp. z o.o. was established in 1993 as THOMAS TV Sp. z o.o. The first activity of the company was the installation and maintenance of cable television networks, and the first projects were realized for ELEKTRIM TV Sp. z o.o. These experiences allowed us to gain practical knowledge in realization of investments, making inventory and accounting for it.

The next stages of our development were closely related to accounting and finance. Working with other clients we gained the experience, among others, of organizing the circulation of documents, consolidation of financial statements, corporate reporting and others.

Quality Management System

People make mistakes. Sometimes they are a source of great discoveries and inventions, however, much more often they are the cause unnecessary costs, worries and frustrations. People make mistakes. It is a truth which very often is difficult to accept. However, if we accept it, we will begin to find ways to limit their impact and eliminate in them in the future.

In 2007, we have implemented a Quality Management System according to ISO 9001. We continuously monitor emerging inconsistencies and improve processes to eliminate their causes. Every year, DAS Polska carries out an external audit to confirm the correctness of actions carried out by us in this area.

If you have comments regarding our work (both positive and negative) write to our Quality Manager (szj[@]thomas.pl). We will use them to improve our work for you.

IAPA International

Every day we meet new people and come up with new ways of developing our business. More and more often, we consider making a start abroad, but equally often we give up not having proper knowledge or fearing the high price of acquiring it.

IAPA International was created in response to these challenges. Our members and partners are present worldwide, supporting our clients in the areas of accounting, taxes and auditing. They also provide support in other issues related to starting and running a business abroad.

Cooperation with our international partners is also open to clients of other companies in the accounting and advisory sector, i.e. our competitors. We guarantee not to take steps to establish cooperation with their clients in the areas supported by these companies, focusing exclusively on international cooperation.

You can learn more about the IAPA International and find our partners on the organization’s website.
