TeamSystem expands into Türkiye with DIA Yazılım

TeamSystem – an Italian tech & AI company leading the development of digital platforms for business management for companies and professionals – has acquired ACD, a major French provider of accounting and management software for accounting firms and professionals.
The acquisition reinforces TeamSystem’s role as a European champion for the digitalisation of SMEs and professionals and further strengthens its footprint in France, where administrative and tax processes are undergoing a profound transformation driven by the gradual introduction of mandatory electronic invoicing, following the model already implemented in Italy.
Founded in 2004, ACD has progressively established itself as a leading technology partner for French accounting firms, developing solutions that are seamlessly integrated into their daily workflows. Today, the company serves the needs of approximately 3,200 firms and indirectly supports more than 1.3 million businesses. With offices in Tours and Aix-en-Provence, ACD recorded revenues of around €35 million in 2024, employing more than 280 people. Over the years, it has developed an offering designed to benefit the core activities of firms, ranging from accounting production and practice management to CRM, document management and payroll solutions. Based on cloud and SaaS platforms, its business model leverages advanced AI-powered capabilities to unlock innovation and drive the digital transformation of accounting firms.
“Given the importance of professional services firms in its economic system and the profound transformation under way in administrative and tax processes, France plays a strategic role in our European growth journey,” said Federico Leproux, CEO of TeamSystem. “The French context is closely aligned with Italy’s, where electronic invoicing marked a milestone in the digitalisation of companies and SMEs. With the acquisition of ACD, we aim to bring this expertise to France, supporting professionals in their daily activities and helping them navigate the digital transformation.”
Additionally, TeamSystem has also expanded its cloud-based management software offering with the acquisition of DIA Yazılım, a well-established technology player based in Türkiye. With over 100 employees and a strong presence in the local market, serving tens of thousands of users, the company provides modular and scalable cloud ERP solutions to support the operational and regulatory needs of SMEs.
Both operations are testament to TeamSystem’s international expansion, as the Group continues to invest in markets with needs and dynamics similar to those in Italy, exporting a proven and scalable business model.
“The acquisition of DIA further accelerates our growth in Türkiye. In line with our other key markets, we have adopted a long-term approach based on pursuing targeted investments, capitalising on local expertise and implementing solutions that meet the needs of SMEs, where efficiency and user experience are increasingly driving digitalisation,” added Leproux.
