Industry: Banking
Scope: Payroll and HR outsourcing for large employers
Cooperation period: Since July 2008


Banking is one of the industries in which payroll and HR outsourcing must combine high scalability with stringent regulatory requirements.


This case study demonstrates how Aider Polska (MDDP Outsourcing) has been supporting the Polish branch of a Scandinavian bank since 2008 by providing comprehensive payroll and HR services, ensuring efficient HR and payroll operations as the workforce grew from 39 to 269 employees (as of May 2026), with all employees hired exclusively under employment contracts.


Background and Scale of the Cooperation


The client is the Polish branch of a Scandinavian bank operating from a single location in Poland. The cooperation began in July 2008, when the organization employed 39 people. Over the following years, the company experienced steady growth. As of May 2026, Aider Polska provides payroll and HR outsourcing services for 269 employees, all of whom have been employed under employment contracts since the beginning of the cooperation.

The Client's Challenge


From the outset, the bank's operating model in Poland assumed the outsourcing of payroll and HR processes. Due to the specific nature of the banking industry—subject to extensive regulatory supervision—and the planned, steady increase in headcount, the client sought a payroll and HR service provider capable of combining strong technical expertise with the ability to scale services as the workforce expanded, without compromising quality or process timeliness.


Importantly, the project has been delivered without any system integration with the client's internal systems. This demonstrates that high-quality payroll and HR outsourcing does not always require advanced IT integration. Instead, success depends primarily on well-designed processes and effective reporting tools.

Scalable processes, electronic employee records, and comprehensive HR and payroll reporting enable organizations to support a growing workforce without compromising service quality, timeliness, or regulatory compliance.
