EFF, a Medius partner
EFF was first introduced to Medius through one of our clients, Candyking, when they decided to change their invoice workflow solution back in 2015. As the provider of accounting services to Candyking, our team played a key role in the implementation project — from testing all required functionalities to ensuring a successful go-live and managing the workflow thereafter.
Since then, our expertise with Medius solutions has grown substantially through involvement in numerous client projects across various industries. This extensive experience has led EFF to become a trusted Medius partner, supporting companies that want to streamline, optimise, or outsource their accounts payable operations — whether fully or partially — through the Medius platform.
EFF’s team brings a deep understanding of both the technical functionality and the financial process management behind Medius. We provide more than just implementation — we act as consultants and partners, helping clients make the most of their automation journey. From workflow design and system configuration to ongoing administration and support, we are there every step of the way to ensure the solution delivers measurable results.
Whether you are already using Medius or considering invoice automation for the first time, EFF can provide expert advice, tailored configuration, and dedicated hands-on support to ensure seamless integration and continuous improvement across your financial operations.
