Why Kewos
The power of an ERP, without the legacy debt
Kewos does what legacy suites do — with a clean architecture, predictable performance and security by construction. Zero hidden magic.
Security by construction
RBAC, record rules and field rules are enforced in the ORM — never only in the API. Access is denied by default and fully audited.
Predictable performance
No sneaky N+1, controlled queries, a declarative view engine. Your instance stays fast as it grows.
Native compliance
Tamper-proof legal numbering, immutable entries, e-invoicing and GDPR baked into the core — not bolted on.
Extensible without forking
Runtime fields, automations, views and workflows are configured without touching code — and stay upgrade-safe.
Sovereign & European
Your data lives in Europe, one database per customer. Deploy on-premise under licence when sovereignty demands it.
Mandate-ready
E-invoicing, built in — not bolted on
France mandates B2B e-invoicing (2026/2027). Kewos natively generates, sends and receives compliant invoices, with a calendar of rates and obligations versioned by effective date.
- Factur-X (PDF/A-3), UBL 2.1 and CII formats supported
- Platform connectivity (Chorus Pro / PPF, PDP) with circuit-breaker and audit
- Lifecycle and CDAR statuses tracked per invoice
- VAT rates and schedules are dated data, never hard-coded
SaaS or on-premise
The same product. Your infrastructure, your choice.
Unlike solutions that fork their code, Kewos ships the exact same core in multi-tenant cloud or on your own servers. No watered-down features per mode.
Sovereign cloud
We run it for you, hosted in Europe.
- One isolated database per customer
- Updates, backups and monitoring included
- Transparent storage and compute quotas
- Dedicated subdomain, automatic TLS
On-premise
On your servers, under licence, in your control.
- Docker / Helm deployment
- Signed licence, hardware fingerprint
- Full data sovereignty
- Ideal for regulated sectors
Same code, same modules, same security — the difference is configuration, never hidden branches.
