Antwerp accounting and tax firm website: local agency prices or Kolonell? (2026)

The verdict in three sentences

In Antwerp, an accounting and tax firm website costs a 2026 ballpark of 6 000 to 30 000+ EUR from a local agency and 2 500 to 8 000 EUR from a freelancer, with trilingual Dutch, French and English sites at the top of the range. Kolonell builds the English site at a fixed 2 700, 4 500 or 8 200 EUR in 3 to 4 weeks, with native English copy and a project manager on calls during Belgian office hours. For a firm whose new clients are foreign subsidiaries, port and logistics companies and expat professionals, the English site is where mandates are won, and it does not need a 20 000 EUR budget.

Local agency, freelancer or Kolonell: which fits your firm?

Before comparing prices, match the provider to what the site has to do. This table is a decision aid, not a ranking.

What do Antwerp providers charge in 2026?

The ranges are prudent orders of magnitude drawn from the public rate cards of Belgian agencies, the minimum project sizes listed on Clutch.co agency profiles and the rates visible on freelance platforms such as Malt and Upwork. They vary with scope, languages and integrations.

The content of each tier is described on our international website offer. Payment is by bank transfer or Wise, 50 % at kickoff and 50 % at delivery. The team works on GMT, one or two hours behind Antwerp, so Google Meet calls fit your day and a written update arrives every week.

What does an Antwerp accounting and tax firm site need?

Antwerp firms with an international practice often serve foreign subsidiaries setting up near the port, logistics and trading companies, the diamond and commodities trade, expat employees and their families, and Belgian companies with foreign shareholders. A site that turns these visitors into meetings usually includes:

• Service pages: bookkeeping, payroll (often with a social secretariat partner), annual accounts, corporate and personal income tax, VAT returns, company formation, advisory, and international or expat tax if you offer it.
• Client-type pages: foreign subsidiaries, logistics and trading companies, expats, startups. Each explains what you take on and how the first month goes.
• A team page with real qualifications and the languages each person speaks.
• Booking and onboarding: an embedded calendar and a short engagement request form, no document upload on the public site.
• Secure document exchange: a link or embed to the portal you already use is included; a custom portal, or a custom integration with your accounting software, is quoted on request.
• Resources: a general tax calendar and explainers, with no individual tax advice and no promised savings.

On compliance, the GDPR applies to every form and file exchange, and accounting clients send sensitive financial and identity data. Belgian accountants and tax advisers are members of the ITAA, whose rules cover advertising and protected titles: the firm checks them itself and only uses titles it holds. Accountants also have AML obligations. The European Accessibility Act has applied to certain services since 28 June 2025; check whether it covers yours. This is not legal advice.

What will it cost over three years?

Illustrative comparison with the same assumptions for all options: hosting at 25 EUR a month and maintenance at 90 EUR a month from month 4 to month 36. Kolonell maintenance after the included support is quoted on request; the assumption only makes the comparison fair.

When you compare quotes, ask for the page list, the copywriting arrangement per language, the hourly rate after launch and written confirmation that the domain is registered in the firm's name. A quote that is vague on any of these is a red flag.

Mini case study

Illustrative example: Koen is a partner in a six-person firm in Berchem. Most new mandates come from foreign subsidiaries and logistics companies around the port. A local agency quotes 17 500 EUR for a Dutch and English site in 10 weeks. He picks Kolonell Growth at 4 500 EUR for the English site, live in 4 weeks, and his team supplies the Dutch pages. With the hosting and maintenance assumption above, the three-year totals are 21 370 EUR against 8 370 EUR: 13 000 EUR kept in the firm.
