    Solutions for business sectors

    In a world of shifting regulations, rapid technological advancement, and rising customer expectations — one-size-fits-all solutions simply don’t work. That’s why we’ve developed a service offering tailored to the real needs of your sector. This gives you more time, less stress, and tangible support in growing your business.

    What we offer

    We tailor our services to your needs; following a conversation and analysis, we propose next steps that deliver measurable results — streamlining daily operations, saving time, reducing unnecessary risk, and helping you focus on the direction you want your business to grow in.

    We understand that manufacturing companies focus on optimizing raw material usage and supply management, that e-commerce faces increasing competition and customer demands, and that shared service centers need efficient, repeatable processes. That’s why instead of predefined scenarios, we offer support tailored to your growth pace, work style, and business model.

    Why EFF

    We work with companies at every stage of development — from startups to mature enterprises and international groups. Our clients have trusted us because they were looking for — and found — a partner who understands business and thinks long-term. We know the realities of specific industries — regulations, challenges, seasonality, and dynamics. That’s why we offer solutions that actually work.

    Work with us
    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. We can always count on their reliable advice and prompt answers to all of our questions. Duni EFF experts’ big commitment and individual approach to a client cannot go unnoticed. Their high competence and vast professional knowledge ensure all our needs are met and it facilitates efficient cooperation.
    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.
    Jorg Schulz, Sales Director
    We at Euroflorist are very pleased with EFF's high competence and ability to adapt to our changing needs.
    Per Gränse, CFO, Euroflorist
    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.
    Miłosz Wójcik, Chief Product Officer Nethansa
    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.
    Sophie Thompson, Payroll Specialist, Cloetta UK
