Fortnox is a Swedish cloud-based business platform founded in 2001 and listed on Nasdaq Stockholm. The company provides integrated software solutions for accounting, invoicing, payroll, and financing to over 500,000 businesses across Sweden. Its platform connects companies, users, and partner integrations through a REST API designed for developers.
The platform serves small and medium-sized businesses, accounting firms, and organisations seeking digital tools to manage core financial and administrative functions. Fortnox positions itself as an ecosystem rather than a single-purpose application, allowing third-party developers to build integrations and extend functionality through its open API architecture.
Beyond traditional business software, Fortnox has expanded into financing solutions through acquisitions including Capcito. This diversification reflects the company's strategy to become a comprehensive hub for business management rather than a standalone accounting tool.
