From application to approval in 16 days: how we secured a commercial permit for a Paris-based e-commerce founder

Marie L. sells home and living products to customers across Western Europe. By spring 2026 her warehouse contract in France was running out, Luxembourg's logistics position made sense for the next lease, and her Sàrl was already registered here. One thing was missing: the business permit that makes a company allowed to trade.

The application had been sitting on her desk for two months. Not because it is long, but because every field seemed to hide a way to get it wrong.

Where the application stalls

Luxembourg's autorisation d'établissement rests on three checks: professional qualification, professional integrity, and a fixed physical establishment in the country. None of them is exotic. What stalls founders is the evidence: which documents prove qualification for a commercial activity, what counts as a compliant address, and how a foreign career translates into the Ministry's categories.

Marie had a French business degree, six years of running her own company, and a pile of documents in the wrong shape. Her draft application also listed the activity so narrowly that a future product line would have needed a second permit.

What we changed before submitting

• The activity description. Rewritten so it covers her actual trade today and the two directions she plans next, without drifting into activities that trigger extra requirements.
• The evidence file. Her degree, her French company extract and proof of management experience, assembled in the order the Ministry reads them, with translations only where they matter.
• The address. Her planned warehouse did not qualify as a fixed establishment on its own; a compliant registered address closed that gap before it could become a rejection letter.

Sixteen days

The completed file went to the Ministry with every supporting document attached on day one. No queries came back. The authorisation was issued sixteen days after submission, without a single request for clarification.

The two months of hesitation turned out to be the expensive part. The application itself, once complete, was quick.

What the permit unlocked

With the authorisation in place, the pieces Marie had been holding fell into line within weeks: the warehouse lease signed, the bank account activated for operations, and her first Luxembourg hire posted.
