A leading provider of outsourced administration services, with a global presence: “We deliver consolidation services to a highly discriminating clientele with various profiles. We have extensive expertise in addressing the difficult consolidation issues that arise with international groups of companies that must comply with local GAAP or IFRS. To provide the best service to our clients we needed a reliable and flexible tool as well as efficient technical support. The web-based technology of Mona Group Reporting and the expertise of Sigma Conso were key in our decision to work with them.”

An investment holding company, exchange listed: “We were looking at replacing our old consolidation software. Based on the survey we performed, Mona Group Reporting quickly appeared to be the best match for our needs. Sigma Conso was fully responsible for managing the implementation project. Not only did they meet the deadline and respect the budget but the team in charge of the project also demonstrated an outstanding level of expertise: Sigma Conso conducted the project in full autonomy, leaving our team time to deal with our current business.”

We have more than 150 entities all over the world and we especially appreciate the multi-currency capability of the solution and the fact that it is fully web-based, making it possible to involve all of our subsidiaries in the process.
