## The panel's verdict

Fenerum, from Fenerum ApS of Denmark (CVR 40430989), is subscription billing for B2B SaaS with automatic booking into the accounting system. Scoring is strongest on revenue and handoff at 6-7 and sovereignty at 7: judges credit real-time automatic booking with chart-of-accounts and general-ledger postings, sixteen webhook events, a data processing agreement in the master service agreement, and a published subprocessor list naming registration and processing countries. Collections and dunning scored 6-7 on SEPA direct debit via Stripe across all 36 SEPA countries and an API handover of nonpaying invoices to Likvido. Tax handling is weakest at 4: VAT rates sync from the connected accounting system, and we found no public information on reverse charge, VAT ID validation, One-Stop-Shop or US sales tax. Invoicing compliance ranged 5-6; we found no public information on XRechnung, ZUGFeRD or sequential numbering. Pricing transparency scored 6-7: Core is free up to 50.000 DKK MRR, Plus 1.149 DKK per month up to 100.000 DKK MRR, Enterprise Contact us from 8.000.000+ MRR, with no published price between those bands and the VAT treatment of prices not stated.

**Speaks for it:**
- Real-time automatic booking into the accounting system, with chart-of-accounts entries and general-ledger postings exposed in the API
- SEPA direct debit via Stripe covers all 36 SEPA countries
- A published subprocessor list gives registration and processing countries for every provider
- Two deferred-revenue reports plus a financial audit overview and deviation report support reconciliation
- The vendor states it charges no percentage of revenue and nothing per invoice, with unlimited customers and invoice volume on every tier

**Held against it:**
- We found no public information on reverse charge, VAT ID validation, One-Stop-Shop reporting or US sales tax, with VAT codes synced in from the connected accounting system
- We found no public information on XRechnung, ZUGFeRD, sequential numbering or retention and archiving standards
- We found no public information on trials, proration or usage-based metering
- The vendor states that a list of discount agreements cannot currently be exported
- The captured pages give different information on the availability of the Likvido debt-collection integration

**Best for:**
- You run B2B SaaS subscriptions and need real-time automatic booking into your accounting system with deferred-revenue and churn reporting
- You collect recurring payments by SEPA direct debit across the 36 SEPA countries via Stripe
- You send EAN invoices to Danish public bodies or Peppol e-invoices, documented through named subprocessors
- Your MRR falls inside a published band — Core free up to 50.000 DKK MRR or Plus 1.149 DKK per month up to 100.000 DKK MRR — so you can compute your cost from public pages

**Avoid if:**
- You need tax determination inside the billing product — VAT codes and rates are synced in from the connected accounting system
- Your MRR exceeds the Plus cap of 100.000 DKK, where published pricing stops and Enterprise from 8.000.000+ MRR is Contact us
- You want a short commitment — the minimum term is 12 months
- You need a complete successor-ready export, since the vendor states a list of discount agreements cannot currently be exported

## 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.
