Launch Order
- Serbia FIRST - SEF operational, largest opportunity, e-invoicing driving adoption NOW
- Croatia SECOND - HR-FISK launching Jan 2026, EU compliance adds credibility
- BiH THIRD - Wait for CPF specs (2027), build locale/tax early
Competitive Strategy
- Compete on UX - Pantheon = ERP (complex), Bilko = accounting (simple). Fiken model.
- Compete on price - Pantheon charges "secretary salary" equivalent. Undercut.
- Compete on cloud-native - Minimax closest but older architecture
- Local language + compliance = moat - QuickBooks/Xero can't compete here
