The problem

What your current billing setup costs every week.

Three line items that never appear on an invoice – but that you pay every quarter.

Engineering time

Your product team is building billing instead of product.

Twelve documented blueprints with ready-made API calls – your first invoice goes out in hours.
Compliance risk

Tax and invoice errors only surface at the customer or at closing time.

Every invoice is Schematron-validated before it leaves; the tax logic for 2006/112/EC is built in.
Lost revenue

Failed payments and open receivables are chased manually.

Dunning and R-transaction routing run automatically – failed payments come back on their own.

The platform

Four systems you no longer have to build yourself.

Each system replaces a project of its own on your roadmap – built, audited, and made for Europe.

Monetize

Catalog, versioned pricing, usage, tiers, promotions.

usage.reported × price.v12 → line_items
- Product catalog with full version history
- Usage metering: millions of events, never double-counted
- Tiered pricing, bundles, and promotions with guardrails

Comparison

Where Kontorion wins, and where it doesn't.

Lago, Chargebee and Hyperline are solid products, but they weren't built for EU market requirements. You'll notice the first time you close an OSS quarter.

Answers from the people who built the system.

Our promise: your first OSS filing runs through cleanly – we stay on it until it does.

Start with real data

Is Kontorion a payment provider?

No. Kontorion sits on top of your payment providers: Stripe for cards, GoCardless for SEPA direct debit. You don't need a new PSP contract. Kontorion drives collection, retries and dunning through the providers you already have.

How does migration work?

Most teams are fully migrated in under two weeks. We provide a migration tool and personal support throughout the switch.

Where is my data stored?

In European data centers. Your data never leaves the EU. GDPR compliance is not an add-on, but a foundation of the architecture.

What does Kontorion cost?

After the 14-day trial with real data, from €79/month – cancel monthly, no setup fee. All plans are on the pricing page.

Can I cancel and export my data at any time?

Yes. Kontorion is cancellable monthly, and your data – customers, invoices, accounting data – is fully exportable at any time. No lock-in.

What support do I get at launch?

Migration concierge, blueprint setup, and a direct line to engineering. We stay on it until your first OSS filing runs through cleanly.
