Logon

What Logon does

Logon d.o.o. is a privately held Croatian software company founded in 2003 (incorporated as a limited liability company on May 20, 2010) and headquartered in Ludbreg, Croatia. It develops and sells customized business information systems under the "Link" suite for small and medium enterprises, local government units (JLS), budget users, and educational institutions in Croatia. The flagship product is SEUP Link 5 (Sustav elektroničkog uredskog poslovanja), an electronic office management system fully aligned with Croatian Office Management Regulation NN 75/2021 and equipped with ZUP IT certification, eDelivery access point, qualified digital signature integration (FINA, AKD, SWIScom), OCR for paper documents, and e-invoice ingestion via Moj e-račun and FINA e-računi. The platform architecture consists of approximately 17 interconnected modules — financial operations, budgeting, payroll, HR records, municipal/communal operations, sales and invoicing, VAT, cash management, fixed assets, incoming invoices, materials and merchandise, travel orders, payment orders, and contract registries — sharing a common database to eliminate duplicate data entry.

The technology stack is Microsoft .NET 7.0 with C#, supporting either Microsoft SQL Server 2022 (Express or licensed) or PostgreSQL back-ends, and is delivered either on customer premises or hosted by Logon. Logon's go-to-market is sales-led: programs are adapted to customer requirements with pre-agreed pricing, sold via direct outreach, and supported through phone, email, Anydesk remote sessions, and a Zendesk-based support portal. Revenue is generated from three streams: one-time customized software licenses, annual flat-rate maintenance subscriptions covering updates, legal changes, and remote support during business hours, and usage-based professional services for on-demand interventions, training, and on-site visits. Headcount is reported in the 11–50 range; the company maintains a single Croatian office and is privately held by director Renata Blatarić with no disclosed external funding, parent entity, or subsidiaries.

Customer references span 20+ Croatian counties and include SME clients as well as recognizable anchors such as Philip Morris affiliates in Croatia, Korea, Serbia (Niš), and Ukraine; cities of Ludbreg and Daruvar; Nacionalni park Plitvička jezera; Hrvatska komora arhitekata; and faculties of the University of Zagreb. Operational activity in the last five years has centered on regulatory compliance (full SEUP NN 75/2021 alignment and ZUP IT certification in September 2023), an office relocation in August 2022, a Zendesk support portal launch in September 2018, e-invoice service integration with Moj e-račun and FINA in December 2019, and a refreshed service price list effective May 1, 2024. Revenue, ARR, headcount direction, and customer churn metrics are not publicly disclosed.
