One product, many markets

One product, many markets.

Kontier is one billing engine serving multiple European markets: Germany with XRechnung and DATEV, France with Factur-X, and EU-wide VAT, OSS and reverse-charge handling for every member state.

Why Europe is different

Global billing tools stop where European complexity begins.

US-centric billing

  • Subscription
  • Card
  • Invoice

European reality

  • Subscription
  • Usage
  • VAT
  • Reverse charge
  • E-Rechnung
  • SEPA
  • Accounting
  • Country requirements

One revenue layer

Pricing, tax, invoicing and collections - one consistent lifecycle.

Pricing leads to billing, leads to tax, leads to invoice, leads to collections, leads to accounting.

Designed for expansion

Add markets without rebuilding billing.

Expanding across Europe shouldn't mean a new billing architecture for every country you enter. Kontier is built so VAT rules, invoicing formats and accounting handoffs scale with your business - not against it - as you add markets.

Stop maintaining billing infrastructure.

Build your product. Let Kontier handle the revenue machinery.
