Start a business in Luxembourg: 10-day digital checklist

You’ve just registered your business in Luxembourg. The SARL-s is created, the RCS number is in, the pro bank account is open. Congratulations. Now starts the phase that determines your first six months: laying the digital foundations correctly, in the right order, without panicking.

Most new directors rush into the wrong topics — €800 logo creation, €12,000 website rebuild, complete marketing plan — before having a pro email that works. Result: 3 months later, the site still isn’t live, the first potential clients don’t know where to look, and the launch budget is consumed.

Here’s the day-by-day checklist for the first 10 days, in logical order. Each day has a concrete action, doable solo or with a provider — no step confusion.

Why the first 10 days count

The first potential clients of a new business often come from immediate word-of-mouth: professional network, former colleagues, neighbours, partners. They search for you on Google as soon as they hear about you.

If at that moment you have no website (even minimal), no Google Business listing, no pro email at your domain — you lose these first signals. And losing the first 10 prospects of week 1 means losing the 10 potential testimonials that would have fed the word-of-mouth for the following 6 months.

The next 10 days don’t create a perfect presence. They create the foundations so the work of the following 90 days can build on top.

D1-D3: Digital identity

Day 1 — The domain name. Buy your .lu (and .com if available, to protect the brand) at a registrar — directly in your name, not via a provider who’d put it in theirs. Configure auto-renewal and note the credentials in a pro password manager. Duration: 1 hour. Cost: marginal.

Day 2 — Pro email at your domain. firstname@yourcompany.lu rather than a Gmail address. Google Workspace or equivalent, configuration in 30 minutes. Also configure contact@, hello@ and an alias forwarded to your main inbox.

Day 3 — Administrative verification. Check that the coordinates that will appear publicly (on the site, in directories, on Google) are perfectly consistent: legal company name, exact registered office address, definitive phone number, pro email. This NAP consistency (Name, Address, Phone) is the foundation of local SEO.

D4-D6: Legal and operational framework

Day 4 — Legal notice and privacy policy. Prepare the mandatory texts: legal notice (company name, RCS, registered office, publication manager, hosting provider) and GDPR-compliant privacy policy. More detail in GDPR and website in Luxembourg: complete checklist.

Day 5 — GDPR basics before data collection. Prepare the cookies banner, internal procedure for GDPR requests, and a simple processing register.

Day 6 — Pro presence on LinkedIn and directories. Update your personal LinkedIn profile with your new role. Create the LinkedIn company page. Register your business in relevant Luxembourg sectoral directories (Chamber of Trades if artisan, professional federations, sectoral associations). These are your first backlinks and consistency signals for Google.

D7-D8: First digital point of contact

Day 7 — Temporary one-pager site. Don’t chase a complete 20-page site. Put online a single page with: who you are, what you offer, how to contact you, legal notice. Five sections, one page.

The INNOVALUX SARL-s case shows what we should aim for even at startup: fast site (loading under a second), clear structure, complete mentions. No need to wait for a substantial budget to do things right.

Day 8 — Quote or appointment booking tool. Depending on your activity, configure the tool that will receive first requests: Calendly/Cal.com for appointments, a quote form on the site, or simply an easily accessible email. Topic covered in how to book appointments online in Luxembourg.

D9-D10: Measure from the start

Day 9 — Google Business Profile. Probably the most rentable action on the list, especially if your activity has a local dimension. Create the listing, verify it, fill it completely: precise category, service area, hours, detailed services, quality photos, 3-5 posts. For the complete mechanism, see Google My Business: complete guide.

Day 10 — Analytics and basic measurement. Configure Google Analytics 4 (with IP anonymisation) and Google Search Console from day 10. Submit the sitemap. First data arrives within 24-72h.

Classic pitfalls

A few pitfalls we see repeating with new directors in Luxembourg:

• Buying a domain in the provider’s name. Always in your name. Topic detailed in reclaim your website when the agency stops responding.
• Oversizing the first site. 20 pages, blog, e-shop, member area — you won’t keep up with content. A well-done one-pager beats an abandoned big site.
• Neglecting Google Business Profile. For local, that’s 50% of referencing. Doing it on day 9 rather than month 6 changes the entire trajectory.
• Forgetting legal notice. Potential first fine as soon as an unhappy client or competitor looks at your site.
• Putting online with Disallow: / in robots.txt. Developer forgot to remove it — Google sees nothing for 3 months. Check before day 11.

What you can postpone

In the marketing noise, many things can wait:

• Complete site rebuild — at month 3-6 once you know what works.
• Professional designer logo — at month 2-3, after first client feedback.
• 50-article content plan — at month 2 once you’ve identified the first recurring client questions.
• Instagram / TikTok presence — depends on your sector. For 80% of B2B activities in Luxembourg, it’s misplaced effort for the first 6 months.
• Newsletter — before having an audience, it’s talking to yourself. Wait for 200-300 relevant contacts.

No commitment · Reply within 24h · Luxembourg — that’s the clean start signature: lay what counts, await the first signals, adjust from real data rather than preconceptions.

Frequently asked questions

Should I create the SARL-s before the website, or the opposite?

The SARL-s first. Without an RCS number, you can’t have legally compliant legal notices, so no legally publishable website. The sequence is: registration → pro bank account → 10-day digital checklist.

How much does this 10-day checklist reasonably cost?

The only fixed costs: domain name (tens of euros/year), Google Workspace pro email (about a dozen euros/month per user), Calendly or equivalent if needed (free or low tier). The rest — one-pager site, Google Business listing, analytics — has no tool cost. The real cost is in time: 30-50 hours over 10 days if you do it yourself, or in services if you delegate.

Can I do it all alone or do I need a provider?

The first 6 days (domain, emails, legal notice, basic GDPR, LinkedIn) are doable alone if you’re comfortable with tools. Day 7 (one-pager site) requires either technical skills or a provider. Days 8-10 (RDV, Google Business, analytics) are doable alone with patience.

Which channel brings clients fastest when starting?

For 80% of B2B and B2C local activities in Luxembourg, it’s the well-configured Google Business Profile + word-of-mouth from your immediate network. The website becomes the second channel after 2-4 months. Trajectory detailed in how long before a website brings clients.
