Euleo is a company with over 20 years of experience in receivables management and the legal and financial protection of entrepreneurs. Tandemite played the role of Euleo's strategic partner in its web projects.

Design Challenge

The company Euleo has been dealing with debt collection and the related services for many years. It decided to create an online platform for enterprises from the B2B sector, which would enable the effective management of their receivables.

When creating the solution for Euleo, we faced many challenges. First and foremost, we had to design a solution that would allow entrepreneurs to manage a company’s receivables comprehensively – it had to provide preventive tools, facilitate the control of the recovery process and ultimately enable debt recovery.

To properly fulfil its function, the platform we created also had to be integrated with the internal IT systems used by Euleo.



We realised that there were no ready-made solutions on the market that would meet all the needs and expectations Euleo had laid out when they approached us. It was therefore necessary to create an appropriate base system.

In the first stage of the work, our team had to fully understand what tools Euleo wanted to offer to its clients. To make this possible, we took steps in the field of conceptual and strategic consulting.

During the project meetings, we were able to define the assumptions of the application, as well as finding room for improvements in the client’s internal system. As a result, many of the analytical tools used by Euleo had to be automated.

Implementation details

Our cooperation with Euleo included:

  • Business analytics
  • Internet analytics
  • Technological and UX audits
  • Taking care of the websites
  • Software and its implementation
  • Functional design
  • Graphic design
  • Technical assistance
  • Permanent cooperation

Stage 4: Finish


Our team created numerous solutions for the field of business intelligence, which opened Euleo – that had previously operating outside the Internet – to online activities. The system designed by Tandemite got the company up and running, by providing its clients with useful tools for managing their receivables.

We created a Receivables Management System from scratch on the Prudent Company platform that was also designed by us. Among other features, it enables the monitoring of invoices, thereby reducing the risk of lost funds. Due to the modular design of the system, it can be easily scaled and integrated via an API with external applications.

In addition, we created an additional website for Euleo: the debt and receivables exchange Among others features, it allows the publication of debts for sale, purchases of debts and the verification of contractors.

Thanks to our many years of cooperation with Euleo, we have been able to deepen our knowledge of the financial industry and of issues related to fintech.
