Website redesign for an accounting and tax firm in Antwerp: budget, timeline and risks (2026)

The verdict in three sentences

An accounting and tax firm in Antwerp redesigning its website in 2026 should budget, as a ballpark, EUR 6,000 to 22,000 with a local agency, against a fixed EUR 4,500 (Growth) or EUR 8,200 (Premium) with Kolonell, while any client portal or secure document upload stays a separate line on quote. The value of the redesign sits in clear service pages (bookkeeping, VAT, corporate tax, payroll coordination, advice for SMEs and expatriates) written in Dutch first, with English and French for international clients around Zuid, Berchem and the port. The risks are predictable: lost rankings on old service URLs, documents sent through open forms, and marketing wording that does not fit professional rules, all of which a URL inventory, a 301 map and a pre-launch compliance review address.

How do you know the firm's site needs a redesign?

Antwerp firms serve owner-managed companies, logistics and port businesses, traders and expatriate professionals. The website often lags behind the practice:

• Service pages are one long list, so a prospect cannot tell whether you handle VAT for import and export or only annual accounts.
• The English page is a short summary, and French speakers from Brussels or Wallonia find nothing.
• Clients email payslips, invoices and ID scans because the contact form has an upload field.
• Old URLs from a previous name or merger still appear in Google and return errors.
• Team pages do not state who is an accredited professional, so prospects ask on the phone.

What budget should an Antwerp firm plan?

Ranges reflect typical quotes and public rate pages of Belgian agencies, in general terms.

All Kolonell tiers include a project manager in your time zone, native English or French copywriting, delivery in 3 to 4 weeks once content is ready and 3 months of support; maintenance afterwards is on quote.

Lines that stay on quote with any provider:

Which risks should you manage, and when?

Three points deserve attention. First, every old service and article URL gets a 301 to its closest new page, never a blanket redirect to the homepage. Second, the contact form collects name, company, email or phone and the service needed; documents go through the portal or your secure channel, not the website. Third, wording such as "the best tax adviser" or guaranteed savings does not belong on an accountant's site: have the copy reviewed against the ITAA's professional rules and include the legal notices Belgian businesses must show. Personal data falls under the GDPR, supervised in Belgium by the Data Protection Authority (APD/GBA). This is not legal advice.

DNS is switched outside office hours, and the old site stays reachable on a staging address for a week.

Questions to ask, and when a local agency wins

Ask every provider: Is the 301 map a file you deliver? Who writes the Dutch, English and French pages, and who reviews technical tax terms? Is the portal linked, embedded or built, and at what price? What does support cover after launch?

A local Antwerp agency is the better choice if you want frequent in-person workshops in Dutch, a new brand after a merger, or a custom portal tightly integrated with your accounting software. Kolonell fits a firm with an established brand that wants a fixed price and a structured redesign in 3 to 4 weeks. As a reference in professional services, Kolonell built the website of TR Signing Group (trsigninggroup.com), a signing services company in New Jersey.

Mini case study

Illustrative example: "Verbeke en Peeters Accountants", a fictional firm of 9 people in Berchem serving SMEs and expatriate professionals, wants Dutch, English and French pages and a link to its existing client portal.

• Kolonell Premium (the multilingual tier, languages set in the quote): EUR 8,200.
• Independent Dutch reviewer for technical tax terms (third-party cost): about EUR 600.
• Maintenance months 4 to 36 at a market assumption of EUR 90 per month (Kolonell maintenance after the 3 included months on quote): 33 x 90 = EUR 2,970.
• Portal link: on quote.

Three-year total excluding the portal: 8,200 + 600 + 2,970 = EUR 11,770, against EUR 14,000 to 22,000 for the build alone with a premium Antwerp agency.

FAQ

How much does an accounting firm website redesign cost in Antwerp?

As a 2026 ballpark, EUR 6,000 to 22,000 with a local agency. Kolonell charges EUR 4,500 for Growth and EUR 8,200 for Premium.

Should clients upload documents through the website?

Not through an open contact form. Use your portal or a secure channel, scoped on quote, and keep the form to 4 or 5 fields.

Do we need Dutch, English and French?

If 15 % or more of your clients are expatriates or French speakers, it is worth it. Premium, at EUR 8,200, is the multilingual tier with languages set in the quote.

How long does the redesign take?

With Kolonell, 3 to 4 weeks once content is ready. Local agencies typically quote 8 to 18 weeks.

Can we keep our current client portal?

Yes, in most cases it is linked or embedded rather than rebuilt. The link is priced on quote and often takes 1 to 3 days of work.
