The craft is the easy part; the admin is what overwhelms people leaving a job to go solo. Registering, VAT, invoicing, contracts, banking — in plain English and in the right order. This is the complete map of the legal and operational layer for a one-person business in Europe, with each step linked to its full guide. Do it in sequence and the admin stops being a 40-tab research spiral.

- France — micro-entrepreneur · running a one-person business in France

- Portugal — recibos verdes
- Ireland — register as a sole trader
- Poland — register a JDG sole proprietorship
- Belgium — register as indépendant · Austria — Gewerbe / Neue Selbständige
- Sweden — F-skatt / enskild firma · Finland — toiminimi
- Greece — self-employed setup · Czechia — živnost / OSVČ
- Denmark — enkeltmandsvirksomhed · Switzerland — self-employed (non-EU)
- Norway — enkeltpersonforetak (EEA, non-EU) · Romania — PFA / self-employed
- EU-wide route — start a business via e-Residency
3. VAT & OSS

- The 2025 cross-border SME VAT scheme — sell VAT-exempt across the EU under €100k.
- VAT for Amazon, Etsy & POD sellers — the €10k threshold and when you must register locally.

The admin layer sets the stage; the money side is in the money guide, and getting found is in the SEO guide. Not sure which kind of solo you are? Find your path.

The takeaway
- EU admin is a sequence: structure & country → register → VAT → invoicing & contracts → banking.
- Start simple (sole trader), form a company when it’s justified; usually register where you live.
- Handle VAT when you cross the threshold or sell cross-border digital products (OSS).
- Compliant invoices, real contracts, a separate business account — the unglamorous basics that prevent the expensive problems.
- It’s country-specific — use these guides to orient, then confirm the details locally.
