What 3 TAV does
3 TAV d.o.o. is a privately held Slovenian software company headquartered in Novo mesto, founded in 2001. It develops and sells the IS21 integrated business information system (ERP), a modular platform with single-entry data architecture spanning finance, accounting, payroll, HR, inventory, warehouse, production, sales, and specialized mass billing for utilities. The company serves medium and large enterprises — primarily municipal and public utility companies, energy distributors, water/wastewater operators, manufacturers, and select government and private-sector accounts — across Slovenia and Croatia. The Moj ECE customer portal (live 2021) extends the platform with microservices architecture (Docker Swarm, GraphQL API, Keycloak SSO, digital signing), and the OptiWaste IoT platform (2022) adds AI/ML-driven waste collection optimization with proprietary recycled-plastic sensors.
Revenue is generated through four streams: (1) subscription software licensing and implementation of IS21 and add-on modules (BI, GIS, DMS/CMS, customer portals, mobile apps); (2) managed billing outsourcing ('data capture to invoice issuance') for utilities; (3) custom software development (mobile apps, vertical solutions); and (4) business and IT consulting. Pricing is quote-based, customized per customer requirements, with multi-year enterprise contracts. GTM is direct enterprise sales (phone, email, website inquiry) with no public SaaS marketplace presence. The technology stack rests on a Vienna Advantage cloud ERP partnership, .NET backend, Microsoft SQL Analysis/Reporting Services for BI, and proprietary AI/ML algorithms developed under EUREKA and EU regional development co-financing. Key certifications include ISO 9001:2015, ISO/IEC 27001:2022, ISO/IEC 27002:2022, GDPR, and ZVDAGA archival compliance.

3 TAV competitors and assessment
Company assessmentBroad incumbents
- SAP: Global ERP incumbent whose utilities and mid-market cloud offerings target the same enterprise customers 3 TAV serves. 3 TAV integrates with SAP rather than replacing it, reflecting SAP as the broader platform incumbent competing for the same budget.
- Infor: Industry-specific cloud ERP vendor with strong manufacturing and distribution verticals. Comparable because Infor targets the same manufacturing and process-industry customers 3 TAV serves via its Industry 4.0 production module.
- Oracle NetSuite: Cloud ERP platform serving mid-market and enterprise customers globally. Targets the same enterprise digital transformation spend that 3 TAV addresses with IS21, particularly for finance, projects, and procurement functions.
- Microsoft Dynamics 365: Microsoft's ERP/CRM cloud suite competing for mid-market and utility digital transformation budgets across Europe. Represents the bundled alternative to 3 TAV's IS21 with strong channel reach.
Direct peers
- SAOP: Slovenian accounting and ERP software provider serving SMEs and mid-market enterprises with payroll, billing, and business process software. Direct competitor for IS21 in the Slovenian market with overlapping utility and manufacturing customers.
- Datalab (Pantheon): Slovenian-headquartered ERP vendor offering Pantheon, a comparable SME/mid-market business information system with accounting, production, and billing modules. Operates in the same Slovenian and broader Adriatic market with overlapping customer base.
- Comarch: Polish-headquartered ERP and utility software vendor with a strong Utility Billing and ERP portfolio. Comparable in its vertical specialization in utilities and CIS-like functionality, and competes for the same European mid-market utility customers.
Regional players
- Visma: European provider of business software and ERP/accounting solutions with strong presence across Nordics and expanding into Central/Southeast Europe. Comparable as a regional SMB/mid-market ERP competitor with local-language accounting and billing.
- Tietoevry: Nordic-headquartered IT services and software vendor with vertical ERP and utility industry software across Northern Europe. Comparable regional incumbent serving utility customers with billing, CRM, and industry-specific modules.
Emerging players
- Vienna Advantage: Open-source/cloud ERP platform that is 3 TAV's technology partner. Comparable because Vienna Advantage also sells customizable cloud ERP directly, and any open-source adoption by utilities could overlap with IS21's mid-market positioning.
