Why now

The Baltic business stack is being rebuilt — in law.

Compliance in the Baltics is no longer paperwork. It is digital, mandatory and machine-readable. Every company will need software underneath it. Someone has to build that layer.

E-Invoicing · PEPPOL
2026

Structured e-invoicing becomes mandatory

Latvia moves to mandatory B2B e-invoicing from 2026, delivered over the PEPPOL network. Paper and PDF stop being compliant. NAUDO is a PEPPOL-native layer from day one.

Construction · EDLUS
100%

Site workforce tracking is the law

Every construction site in Latvia must report worker time through the EDLUS electronic registry. CELTOS turns a legal obligation into automatic check-in data — compliant by default.

Identity · Smart-ID · eParaksts
3M+

National digital identity is universal

Over 3 million Baltic citizens authenticate and sign with Smart-ID and eParaksts. Qualified e-signatures are legally binding EU-wide. We build on this rail — no passwords, no wet ink.

EU · Digitalisation
€10B+

The EU is funding the transition

Billions in EU recovery and digital-decade funding push Baltic SMEs onto digital infrastructure. The demand is created by policy — what's missing is software built for this region, not adapted to it.

Global vendors localise an invoice template and call it Baltic-ready. We start from the regulation — PEPPOL, EDLUS, VID, Smart-ID — and build the company on top of it.

Products

Three operating systems.
One platform underneath.

Each product runs a different part of the business. Together they share clients, documents, identity and finance — one source of truth instead of five disconnected tools.

01 / 03 — Construction

CELTOS

Construction OS

Run construction projects from tender to handover — schedule, budget, site workforce and documentation in one system built for general contractors.

€2.4M budget tracked on a single live project — committed vs. actual, in real time
  • Schedule control — phases, dependencies, today-line
  • EDLUS workforce registry — automatic site check-in, compliant by default
  • Documents & drawings — versioned, e-signed, audit-ready

The platform

Enter data once.
It exists everywhere.

CELTOS, NAUDO and MANTO are not integrations bolted together. They are three views of one platform — the same client, document and identity, shared the moment it's created.

A client created in NAUDO is already in CELTOS. A machine registered in MANTO carries its costs straight into finance.
No sync. No exports. No duplicates.

Baltic-native

Built for how the Baltics actually do business.

Generic software ignores the infrastructure local companies run on. We integrate it natively — identity, signatures, e-invoicing, tax and banks.

IDENTITY

Smart-ID

National-grade authentication for every user. No passwords to manage, no accounts to provision.

SIGNATURES

eParaksts

Qualified electronic signatures on contracts, acts and offers — legally binding across the EU.

E-INVOICING

PEPPOL

Structured e-invoices delivered through the European network, with delivery confirmation built in.

TAX

VID / EDS

Declarations and reports generated from live data and filed with the Latvian tax authority.

CONSTRUCTION

EDLUS

Electronic workforce time registry for construction sites — compliant by default, not by effort.

BANKING

Bank APIs

Direct connections to SEB, Swedbank and Citadele. Payments reconciled the moment they land.

COMPLIANCE

Baltic compliance

Latvian, Lithuanian and Estonian regulation tracked and implemented — so you don't have to.

SECURITY

EU data residency

All data stored and processed inside the European Union, with full audit trails and GDPR controls.
