Partnership models

What partnership models best suits your business and clients?

Back Office Support - EFF acts as your subcontractor – whether you want to expand your portfolio or are looking for support in services you already offer, but lack the knowledge, time, or technology to get this off the ground.
Depending on your requirements, we can operate as a white-label service under your brand or as a third-party partner working under our brand.

Reseller Partnership - if you have a product or solution, EFF can help you sell it through our channels.

Referral Partnership – as our partner, you can gain access to a whole new range of potential customers, and the referral system can work both ways.


Let's discuss the details!

Feel free to contact us for more information on how we can collaborate effectively.

Why is it beneficial for your company to choose EFF as a partner?

What problems within your company can we solve?

Do you want to expand your portfolio of services but lack the resources for additional investment?
By partnering with EFF, your company can expand its portfolio without a need to invest in developing your assets. By providing specialised services, you can help increase your company's overall revenue.

Do you want to implement a new service in a short period of time?
Working with EFF will enable you to quickly get to market and offer EFF services to your company’s portfolio. This solution is especially valuable in a situation when developing new services on your own involves high costs and is a lengthy process.

Don't have access to specialised knowledge?
We give you access to specialised knowledge, skills, and technology that supports your company.

Are you concerned about the financial risk to the business?
Investing in the development of a new service carries financial risk. With EFF, you minimize this risk because your company is not obligated to incur large costs before launching the service.

Would you like to focus on sales and marketing for your business, but lack the time?
Developing a new product or service from scratch is a time-consuming process. A partnership with EFF will save your company time that can be spent on other aspects which will grow your business.

Are you struggling to increase your competitiveness in the market?
Getting access to quality services through partnerships can increase your company's competitiveness, which will result in a significant increase in sales.

  • Across the years of working with Duni 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
  • Duni 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.

  • We at Euroflorist are very pleased with EFF's high competence and ability to adapt to our changing needs.
    Per Gränse
    CEO, Euroflorist
  • During our 5-years of cooperation with EFF we have significantly reduced operating costs and improved quality and transparency of our processes. Very positive and somewhat unexpected for us is how fast and smooth implementations have been.
    Hans Petterson
    Finance Director
  • 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.
