Our passion is supporting our customers to transform their traditional consolidation, forecasting, budgeting cycles into truly value adding business processes and streamline their Financial Close and Tax Reporting processes.


What we do

The name Sonum is the concatenation of the Greek word Sophia which means wisdom and Nummus, the Latin word for coin. Together they embody how we service companies to optimize their business process through connected planning and simplify financial consolidation through sophisticated solutions at the best value for money. Ranging from small projects for local customers to global roll-outs for some of the largest companies in the world.



Sonum International is the connecting link between the business, finance and IT. By tailoring innovative tools to the customers’ needs and requirements, time is freed up to focus on the insights provided and take the best decisions based on reliable data that is available in real-time. Technology is the enabler to streamline the complex processes in a fast-changing environment.


All Sonum consultants are officially certified in the solutions they implement and they are encouraged to take the extra step to become the experts in their field. This approach has led to Sonum becoming highly rated partners of the software vendors we support. Every year new solutions are evaluated to make sure we can advise our customers based on the latest insights on the solutions in the market.


Within Sonum professionals grow by extending their competences through projects. We have seasoned consultants with over 10, 15 and even 20 years of implementation experience still supporting our customers to model the best solutions. Through numerous projects in different industries and covering over 20 different use cases, we have grown a vast knowledge base that is put to work for our customers.

Planning & Business Modelling

The true value of budgeting and forecasting lies in the ability to connect the people, the data and the processes. Enabling people to make decision based on reliable data, presented in a meaningful way and supporting the business processes.

Consolidation and Reporting

Accuracy and confidence in financial reporting are built on repeatable processes and reliable systems. Financial statements provide accountability and maintain the trust of your key stakeholders. Preserving that trust means producing accurate, relevant information within a consistently short timeframe by following the same controlled steps for each close cycle. 

Tool selection

Since Sonum has expertise on and experience with implementing the ‘best-of-breed’ software solutions in the market, we know the advantages and constraints of the different solutions.  In combination with the requirements defined, we advise and support our clients in selecting the best solution to optimize and streamline their processes.

How we are different

There are two facts that make us different from other consulting firms. On one hand, the great variety of EPM tools that we have in our portfolio. And, on the other hand, the team with a mixture of different nationalities makes it possible for us to speak your language.

Our Tools

Here you will find more information about the tools that help make this possible

At Sonum we have proven experience in eight different tools to improve our clients’ planning, budgeting and consolidation processes. Our goal is to deliver quality services to our clients so we invest time each year to test new solutions which can solve our client´s challenges and meet our quality standards.

Highest Partnership level

Due to the number of projects succesfully implemented since the tools were adopted in our portfolio, the number of certified consultants in these solutions and the commercial actions carried out to promote them, we have achieved the highest partnership level in Anaplan and OneStream.
