Billing infrastructure for Europe's regulatory reality.
Kontier unifies EU tax, SEPA and e-invoicing in one platform, built for the reality of 27 member states by a team with decades of enterprise-software experience.
One platform, not three systems.
Subscriptions, payments, EU tax and accounting: most teams assemble this from three separate systems. Kontier delivers it as one integrated platform, built natively for the EU market instead of retrofitted from US products.
- OSS · RC · VIES
EU tax
OSS, reverse charge and VIES checks as core logic, not a plug-in.
- SEPA
SEPA Direct Debit
Part of the billing run, not a separate tool.
- XRECHNUNG · ZUGFERD
E-invoicing
XRechnung and ZUGFeRD/Factur-X, native to the platform.
- DATEV
DATEV export
Accounting as an export, not an afterthought.
Built by people who know enterprise systems.
Behind Kontier is a team with decades of combined enterprise-software experience - people who have built systems that process millions in transactions. We know what billing infrastructure has to withstand before a finance team trusts it. That is exactly what we build Kontier for.
- Decades of enterprise-software experience across the team.
- Built systems that process millions in transactions.
- That discipline is the core of Kontier.
What we hold ourselves to.
Substance over staging
We communicate capabilities, not promises. What you read here is live, and what sits on the roadmap is labelled as roadmap. We hold our software to the same precision.
EU-first
Tax logic, payment methods and e-invoicing are built for the requirements of European finance teams, not adapted. Hosted in the EU, GDPR-native.
Finance-grade correctness
Versioned plans and prices, FX and tax rules frozen at invoice time, a traceable audit log. Existing books are never touched.
Developed in Regensburg.
