The verdict in three sentences
In Luxembourg, redesigning the website of an accounting and tax firm costs roughly EUR 10,000 to 35,000 with a local agency in 2026, against EUR 2,700, 4,500 or 8,200 on Kolonell's fixed grid, delivered in 3 to 4 weeks once content is ready. For a firm in Kirchberg, Gare or Cloche d'Or serving SMEs, holding companies and cross-border workers, the sensitive points are service and fee pages, the client area, and forms that must never collect tax data. Everything else, design included, fits comfortably within a fixed price.
Which signs show it is time to redesign?
- Your service pages mix bookkeeping, company domiciliation, payroll and cross-border tax with no clear path by client type.
- Published fee scales or ranges are several years old, or contradict what partners quote in meetings.
- The contact form invites visitors to attach a tax return, balance sheet or payslip.
- The German or English version is incomplete, although some clients run international holding companies.
- The link to your document upload portal is hidden in the footer.
What budget should you plan, and for what?
Ranges are a 2026 ballpark based on typical Luxembourg agency quotes and public agency rate pages; this is not a market survey.
| Option | What you get | Indicative budget | Timeline |
|---|---|---|---|
| Full-service Luxembourg agency | Workshop, custom design, 3 or 4 languages, integrations | EUR 20,000 to 35,000 | 3 to 6 months |
| Local agency, theme-based redesign | 15 to 25 pages, two languages | EUR 10,000 to 20,000 | 2 to 3 months |
| Freelancer | Theme, simple migration, one language | EUR 4,000 to 10,000 | 6 to 10 weeks |
| Kolonell Starter | Compact site, one language | EUR 2,700 | 3 to 4 weeks |
| Kolonell Growth | Pages by service and client profile, articles | EUR 4,500 | 3 to 4 weeks |
| Kolonell Premium | The multilingual tier, languages set in the quote | EUR 8,200 | 3 to 4 weeks |
Every Kolonell tier includes a project manager reachable in your time zone, native English or French copywriting, delivery in 3 to 4 weeks and 3 months of support. Maintenance after that is on quote. A native German or Luxembourgish review, if you want one, is a third-party cost (independent translator). Details are on the international offer page.
How long does the redesign take, phase by phase?
| Phase | Kolonell (content ready) | Typical local agency | Who signs off at the firm |
|---|---|---|---|
| Scoping, URL inventory, site structure | 3 to 4 days | 2 to 4 weeks | Managing partner |
| Design and mock-ups | 4 to 5 days | 3 to 6 weeks | Managing partner, marketing |
| Copywriting and content build | 5 to 6 days | 3 to 6 weeks | Accountant responsible for each service |
| Compliance review of content | 2 to 3 days | 1 to 2 weeks | Partner, legal counsel if needed |
| Testing, 301 redirects, switchover | 2 to 3 days | 1 to 2 weeks | IT lead |
| Total | 3 to 4 weeks | 2 to 6 months |
The bottleneck is nearly always partners' availability to review. Block two one-hour slots a week for the duration of the project.
Which risks, and how do you control them?
Lost search rankings. Pages such as "company domiciliation", "holding company accounting" or "cross-border tax return" often bring in the enquiries. Full URL inventory, page-by-page 301 redirect map, new sitemap submitted, Search Console monitoring for 8 weeks.
Fees and promises. The profession is regulated; the Order of Chartered Accountants (Ordre des experts-comptables) sets a professional conduct framework your site must respect. Stay factual: fee ranges shown as indicative, no promise of tax savings, no disparaging comparisons. A compliance review of marketing copy before go-live avoids unpleasant surprises.
Forms and data. The GDPR applies, supervised by the CNPD. The public form asks for name, company, contact details, type of need and language, never a tax identification number, income or attachments. Documents go through your secure portal. This is not legal advice.
Client area and upload portals. The site links to your existing tool with a visible button or embeds it in a page; any client area, e-signature or connection to your accounting software is quoted separately.
Downtime. DNS switch on a Friday evening outside filing periods, old site kept ready for rollback.
Kolonell built the website of TR Signing Group (trsigninggroup.com), a signing services company based in New Jersey: a professional services business where clear service descriptions matter as much as they do for an accounting firm.

When is a Luxembourg agency still the better choice?
If you want four languages written by one local team, weekly meetings in Kirchberg, or a custom client area connected to your accounting software, a Luxembourg agency is better placed. Whatever you choose, ask these questions: who delivers the redirect map? Who reviews fee pages before publication? Where is form data hosted? What does maintenance cost after the warranty?
Mini case study
Illustrative example: Claire Hoffeld, partner at Fiduciaire Pétrusse Conseil, a fictional twelve-person firm near the Gare, wants a site in French, English and German.
| Item | Amount |
|---|---|
| Kolonell Premium (the multilingual tier, languages set in the quote) | EUR 8,200 |
| German review by an independent translator (third-party cost) | EUR 1,200 |
| Partners' time: 14 hours valued at EUR 120 | EUR 1,680 |
| Total first-year cost excluding maintenance | EUR 11,080 |
Against a local agency quote of EUR 24,000 for a similar scope, the gap is EUR 12,920. The firm keeps the option of an integrated client area later, quoted separately. For your own figures, request a free quote.
FAQ
Should we publish our fees on the site?
It is not mandatory; many firms show indicative ranges, for example from EUR 150 a month for a small company. Have the wording checked against your professional conduct rules.
How many languages should we plan for in Luxembourg?
French and English cover most SMEs and holding companies; German serves cross-border workers and some clients. Premium at EUR 8,200 is the multilingual tier, languages set in the quote.
Is our document upload portal carried over?
It stays with your vendor, and the site links to it clearly. A deeper integration or a new client area is quoted separately.
How long does the redesign take?
3 to 4 weeks with Kolonell once content is ready, 2 to 6 months with a local agency. Avoid year-end closing months and filing periods.
What does the site cost after launch?
The first 3 months of support are included. After that, maintenance is on quote, based on the number of updates per year.
