For whom?
Who can benefit from our services?
Do you need help in the accounting department of a domestic or a foreign company? Are you looking for support in registering your company or in the correct accounting for VAT? Or maybe you want to handle payroll processes? These and other services are available at EFF.
Why work with EFF?
With many years of experience in the industry, we have a good understanding of how important, yet complex, VAT registration and bookkeeping issues are. Dealing with such processes is time-consuming and requires your full commitment and attention. That's why our team consists of professionals who offer expert accounting and bookkeeping services. We can also take care of VAT registration, payroll and other activities for you, so you can focus on growing your business.
As experts in the industry, what can we offer to our customers?
Above all, a flexible approach and adaptation of the offer to specific requirements, as well as transparency of operations. We provide services in 15 languages, so we can handle international accounting. At the same time, we take care of a comprehensive implementation of each service - whether in the area of accounting, consulting, payroll, company registration or VAT settlement. We also offer contact centre services, such as telephone campaigns in local or foreign languages.
What do we do at EFF?
We operate on the basis of BPO (Business Process Outsourcing), i.e. the transfer of specific areas of operation in a company to our company. That way, you can rest assured that payroll processes, bookkeeping, VAT registration and other necessary activities will be handled in an appropriate manner. This means a reduction in operating costs, as it will reduce the need to employ specialists in the areas concerned.
