Serensia

Serensia is a French software publisher established in 2004 by Emmanuel Flesselles, who also serves as the company's CEO. The firm specializes in the digitization and automation of administrative and accounting processes, carving out a significant niche in the electronic invoicing market. Building on two decades of research and development, Serensia has positioned itself as a key player for companies navigating the mandatory shift to e-invoicing in France and Europe.

The company's core business revolves around providing a comprehensive platform for managing the entire lifecycle of invoices. This includes issuing and receiving compliant electronic invoices, automating purchase-to-pay and order-to-cash workflows, and offering probative archiving to ensure regulatory conformity. Serensia's platform is designed for high-volume processing, handling over 250 million invoices annually with the capacity for peaks of up to 100 invoices per second. The business model appears to be centered on software as a service (SaaS), with offerings available as white-label or grey-label solutions for software publishers and accounting firms that wish to provide their own branded e-invoicing service.

Serensia serves a diverse client base that includes multi-site industrial groups, utilities, banking networks, real estate companies, and public sector entities. A key milestone was achieved when the company was registered as a Partner Dematerialization Platform (PDP) by France's General Directorate of Public Finances (DGFiP), authorizing it to transmit invoices and related data directly to the government's public invoicing portal. This certification, along with its compatibility with the pan-European Peppol network, makes its solution robust for clients with international operations. In a strategic move to bolster its digital financial automation services, Quadient acquired Serensia on June 2, 2025. This acquisition provides Quadient with an operationally mature and certified e-invoicing technology, enhancing its ability to support a vast European customer base through the transition to mandatory digital invoicing.
