Aider Polska – an international group of experts

Aider Polska is not just a local accounting partner—it’s part of an international group that serves companies operating in many European countries on a daily basis.


In Poland, our teams in Warsaw, Katowice, and Lodz consist of nearly 400 specialists in accounting, HR and payroll, and compliance, backed by the entire organization, more than 2,500 experts working within the Aider Group.


This allows us to offer international accounting and HR and payroll services based on common quality standards and a single point of contact.


Each market in which we operate directly is served by local teams who are familiar with local tax regulations, labor laws, and reporting requirements. At the same time, all teams operate within a single group, which allows us to coordinate client services across multiple markets simultaneously, without compromising quality or consistency.

International Accounting, Human Resources, and Payroll Services

In addition to its own offices, Aider Polska collaborates with an extensive network of trusted accounting and HR/payroll firms in other countries across Europe and around the world.


This allows us to provide our clients with:


  • a single point of contact,
  • coordination of projects spanning multiple countries,
  • consistent reporting standards,
  • quality control and timely delivery of locally provided services.

Even if we do not have our own branch in a given country, the client works with a single partner responsible for the entire project.


The Aider Group is systematically expanding its geographic reach. In the coming years, we plan to launch operations in additional countries, expanding both our network of offices and our group of partners. This is a natural response to our clients’ growing need for services that extend beyond the borders of a single country.
