01 — Products

One platform.
Three operating systems.

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.

02 — Why Kaiser Labs

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.

03 — Platform architecture

Three products. One platform.

Every Kaiser product runs on the same shared foundation — so data entered once exists everywhere.

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

04 — Customers

Measured in hours, days and euros.

Companies don't switch software for features. They switch for outcomes.
