Noregna Invoice - Norwegian invoicing & financial SaaS
01 · The problem

Norwegian businesses doing B2B and public-sector invoicing have to handle EHF 3.0, MVA reporting, and audit-grade accounting - but most tools either skip EHF entirely or treat the ledger as an afterthought. Finance teams were exporting CSVs into spreadsheets to reconcile.

02 · What I built

EHF 3.0 + MVA compliance

Automated EHF 3.0 generation for B2B and public-sector invoicing. Norwegian VAT (MVA) calculation, NOK-first multi-currency support, audit-aware logic.

Triple-entry ledger

Verifiable accounting with automated journal entries for every invoice, payment, and credit note. Designed so historical numbers stay correct as data evolves.

Recurring + payment tracking

Subscription invoicing engine for recurring billing, real-time payment tracking with overdue reminders, custom invoice template system.

Reporting + exports

Financial reporting dashboard with NOK-first views, audit-ready data export tools for accountants and regulators.
