Migrate to Kontorion

From Stripe Billing & Chargebee to Kontorion.

Lago, Chargebee and Hyperline are solid products, but they weren't built for EU market requirements. Migrating to Kontorion follows a clear process, typically live in under two weeks.

Why switch

The EU compliance gaps that stand out.

The reasons European teams switch are laid out in full in the comparison on the home page. Here are the key capability gaps at a glance.

01

EU VAT (OSS, reverse charge, VIES)

VAT for the EU single market: OSS, reverse charge and VIES validation, native rather than bolted on. It pays off the first time you close an OSS quarter.

02

XRechnung (native, with Leitweg-ID)

E-invoicing for the German market straight from the platform, including the Leitweg-ID. ZUGFeRD 2.3 and Factur-X as hybrid PDF/A-3 invoices are also live.

03

DATEV export (SKR03/SKR04)

Monthly posting batches with correct BU keys for §13b, OSS and the small-business regime, sent straight to your accountant with no Excel step in between.

04

SEPA Direct Debit (CORE + B2B)

SEPA Direct Debit for CORE and B2B, connected today via GoCardless, with a dunning state machine and R-transaction routing.

05

GoBD-compliant audit trail

A traceable, replay-safe audit trail with plan and price versioning, built for the requirements of European audits.

06

Managed Cloud (EU-only)

Hosted EU-only and GDPR-native. German UI and German-language support are included.

How the switch works

Migrated in four steps.

From connection to production, typically live in under two weeks. No architecture change, one data model for finance, engineering and ops.

  1. 01

    Connect payment providers

    Connect Stripe for cards and GoCardless for SEPA Direct Debit in minutes.

  2. 02

    Configure products & rules

    Set up pricing models, tax logic and invoice templates in one place, not spread across three different tools.

  3. 03

    Parallel run & validation

    Model it in the sandbox with test clocks and validate against your existing setup before billing for real.

  4. 04

    Go to production

    Recurring billing, dunning and EU tax run automatically. Kontorion scales from your first customer to 10,000+ subscriptions.

What Kontorion handles

One system instead of three tools.

Tax, dunning, e-invoicing and accounting export all come together in Kontorion: the same capabilities the platform describes everywhere else.

  • EU VAT / OSS tax engine with reverse charge and VIES
  • Dunning state machine with banking-calendar retries
  • DATEV export (SKR03/SKR04, BU keys)
  • E-invoicing: XRechnung (Leitweg-ID) + ZUGFeRD/Factur-X
  • Wallets, prepaid credit and holds
  • GoBD-compliant audit trail + archiving
