We have the pleasure to work with EFF within VAT Compliance services, which we can honestly recommend for any company seeking a professional support in tax related problems or similar.

Their high competence and vast professional knowledge ensure all our needs are met and it facilitates efficient cooperation.

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.

We at Euroflorist are very pleased with EFF's high competence and ability to adapt to our changing needs.

EFF are tax professionals in the European Union. In cooperation with them, I especially appreciate the individual approach to each case. In international sales, there are often non-standard situations, from which they always find a way out. Their experts have extensive knowledge and provide it in a very accessible way. 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.
