Małgorzata Łysio, Administration Specialist

I would strongly recommend the services of EFF. We have transferred a large part of our AP processes to EFF. The transfer was very efficient and unbureaucratic. The employees of EFF are very ambitious, focused and it is a pleasure to work with them. Thus we were able to increase the reliability and quality of our AP with the same number of employees. Through the competence and experience of EFF, at a good value for money, we can concentrate better on our main business.

Duni EFF is a proven, reliable partner in business.

Across the years of working with EFF, we developed a fantastic professional relationship. Their services to us included AR and AP and I have to say, nothing was ever too much or too little for them to help us with. They were very efficient and knowledgeable, you could say I learned a thing or two from them! It was a pleasure to work with them.
