## The panel's verdict

Younium AB sells subscription management and billing for B2B SaaS. Strongest, at 7 to 8, are the subscription engine, invoicing compliance and revenue and handoff: versioned termed and evergreen subscriptions with flat, quantity, volume, tiered and usage-based charges; Peppol BIS Billing 3.0 built to EN 16931, with the French mandate through Invopop, an approved platform; and revenue recognition to IFRS 15 and ASC 606 beside file-based DATEV export and 20+ native integrations. Tax handling scores 6 to 7 — French statutory rates and US sales tax via TaxJar and Avalara, but we found no public information on VIES validation or One-Stop-Shop reporting. Collections and dunning scores a flat 6: retries are manual and dunning appears only as automated reminders. Sovereignty is weakest at 5 to 6: EU customer data is stated to be stored within Europe and a data processing agreement with standard contractual clauses is available to EU and EEA customers, but hosting is stated only at region level and subprocessors appear only as categories. Scores on every criterion but pricing sit within one point; no prices are published.

**Speaks for it:**
- Versioned termed and evergreen subscriptions supporting flat, quantity, volume, tiered and usage-based charges, amendable through API v2.
- Peppol BIS Billing 3.0 built to EN 16931, with the French mandate delivered through Invopop, an approved platform, and non-compliant invoices blocked before posting.
- Revenue recognition to IFRS 15 and ASC 606 beside a detailed, file-based DATEV export and 20+ named native integrations including NetSuite, QuickBooks and HubSpot.
- Bank reconciliation imports CAMT.053/054, BGMAX and CSV files with automatic matching on OCR number, invoice number or payer name and amount.
- A data processing agreement including the standard contractual clauses is available to EU and EEA customers, and EU customer data is stated to be stored within Europe.

**Held against it:**
- Failed direct-debit payments are retried manually, with dunning described only as automated reminders and no configurable steps shown.
- We found no public information on VIES validation of customer VAT IDs or One-Stop-Shop reporting data.
- Hosting is stated only at region level, and subprocessors appear only as categories such as storage and CRM tools, without names or locations.
- ISO and SOC statements describe alignment rather than certifications held by Younium itself, with the only ISO 27001 certificate named belonging to Invopop, the French e-invoicing partner.
- We found no public information on grandfathered price rollouts, prepaid credits, or a documented path for moving subscriptions and stored payment details to another provider.

**Best for:**
- You run B2B SaaS subscriptions — termed or evergreen, usage-based or tiered — and need every amendment recorded as a versioned change through the API.
- You invoice under the French e-invoicing mandate or over Peppol and need EN 16931-compliant documents with the legally required mentions enforced before posting.
- Your accountant works in DATEV and needs bookable EXTF exports alongside revenue recognition to IFRS 15 and ASC 606.
- You collect by direct debit through GoCardless and reconcile CAMT, BGMAX or CSV bank files.

**Avoid if:**
- You need automatic payment retries and configurable dunning or suspension rules — failed direct-debit payments here are retried manually.
- Your vendor governance requires named subprocessors with locations and vendor-held ISO or SOC certifications.
- Your VAT scope is pan-EU rather than France plus the US — the published VAT evidence is France-shaped, and we found no public information on VIES validation or One-Stop-Shop reporting.
- You must compute an annual cost from public prices before engaging a vendor — ask the vendor: the public pages we read do not show it

## Scores by judge and criterion

Scores out of 5, each judge scoring independently against the published rubric (v1). "n/r" = not rated: the vendor publishes no price, or the judge found no public information on that criterion.

### The judges

- **The SaaS Founder** (v1.0): Runs a twelve-person SaaS that sells to companies in nine EU countries and is about to add a usage-based tier. Wants plans, trials and price changes without a developer sprint, reverse charge that is right without thinking about it, failed cards retried before they turn into churn, and a billing bill that does not grow faster than revenue.
- **The Finance Lead** (v1.0): Closes the month for a software company with eight million euros of recurring revenue. Wants MRR that reconciles with the ledger, deferred revenue scheduled rather than estimated in a spreadsheet, a journal or DATEV export the accountants can book without retyping, and dunning that stops before it reaches a key account.
- **The Billing Engineer** (v1.0): Wires billing into the product and gets paged when a webhook goes missing. Wants a documented API for usage events, idempotent webhooks, entitlements the app can read, a sandbox that behaves like production, and a migration path that moves subscriptions and payment tokens out again if the company outgrows the tool.
- **The Service-Business Owner** (v1.0): Runs an IT service company with two hundred maintenance contracts, hosting packages and monthly retainers, all billed to German businesses. Wants contract terms and price increases handled by the system, SEPA direct debit with mandates, e-invoices that public-sector customers accept, a DATEV export for the tax adviser, and customer data kept in Europe.
- **The Tax Adviser** (v1.0): Advises software and subscription businesses and sees what their billing tools get wrong at the year-end audit. Wants sequential numbering and credit notes instead of edited invoices, XRechnung and ZUGFeRD now that the B2B e-invoice is mandatory, VAT IDs checked before reverse charge is applied, and a merchant of record that says in writing which tax it owes.
- **The Skeptic** (v1.0): Has seen "automated recurring revenue" turn into a tool that takes a percentage of every euro billed and keeps the payment tokens when the customer leaves. Reads "e-invoicing ready" that means a PDF, "global tax compliance" with no word on who is liable, merchant-of-record terms that let the vendor change fees at will, and subprocessor lists that stop at the hosting provider — and asks what leaving would cost.
