The verdict in three sentences
For a 12-person accounting practice in Dublin (benchmarked against Nantes, France), a premium brochure website costs between EUR 6,500 and 11,000 excl. VAT in 2026, and a site with a secure client area (document upload, year-end files, messaging) sits between EUR 14,000 and 22,000 excl. VAT. The "turnkey" sites sold by accounting software vendors at EUR 89-149 per month are enough to exist online, but they rarely generate qualified enquiries from business founders. A conversion-focused site hosted in the EU commonly produces 30 to 60 % more incoming engagement letters within 9 months, which pays back the investment in the first year.
What each budget level covers
Price depends less on page count than on three choices: the depth of service content (pages per service and per client profile), the client area and its security level, and the conversion tooling (fee calculators, booking, qualified forms).
| Option | Typical scope | 2026 budget excl. VAT | Timeline |
|---|---|---|---|
| Vendor "turnkey" site | Shared template, 5-8 pages, generic tax news | EUR 89-149/month | 2-3 weeks |
| Standard custom brochure site | 8-12 pages, clean design, contact form | EUR 4,000-6,500 | 4-6 weeks |
| Premium brochure site | 15-25 pages, founder, property company and professional pages, calculator, local SEO | EUR 6,500-11,000 | 6-9 weeks |
| Premium + secure client area | Document upload, two-factor authentication, archiving, notifications | EUR 14,000-22,000 | 10-14 weeks |
| Client area connected to practice software | Sync with accounting software via API | EUR 22,000 and up | 14-20 weeks |
The gap between premium and vendor sites is content: a founder searching "accountant for new limited company Dublin" must land on a page answering that exact question, with the cost of the engagement, what is included and a bookable call.
Recurring costs and EU hosting
The client area handles tax returns, payslips and ID documents. GDPR and professional body expectations push towards hosting in the European Union, with encryption and access logging.
| Recurring item | 2026 range | Comment |
|---|---|---|
| EU hosting (OVH, Scaleway or equivalent) | EUR 25-60/month | Managed or dedicated server, daily backups |
| Maintenance and updates | EUR 180-350/month | Security patches, monitoring, small changes |
| Certificate and application protection | EUR 0-40/month | Web application firewall, form anti-bot |
| Client document storage | EUR 5-30/month | Depending on volume, encrypted at rest |
| Tax content and SEO | EUR 300-900/month | Optional, 2 to 4 expert articles per month |
| Vendor licence (comparison) | EUR 89-149/month | Shared content, little differentiation |
Over three years, a premium site with client area costs about EUR 18,000 to build plus EUR 9,000 to 16,000 in recurring costs. A vendor site costs EUR 3,200 to 5,400 over the same period, but you remain a tenant of your online presence, and the client area is often the software's own portal, which end clients find clumsy.
What actually moves engagement letters
Practices that see 30 to 60 % more enquiries within 9 months almost all use the same levers: dedicated pages per audience (founders, healthcare professionals, construction trades, family property companies), an indicative fee grid, a simple calculator (engagement cost by turnover), a 20-minute online booking slot and an up-to-date Google Business Profile. The client area plays a different role: it builds loyalty, cuts email chasing and saves staff time.

Claire, partner at a 12-person practice, invests EUR 17,500 excl. VAT in a premium site with client area, plus EUR 290 per month for maintenance and hosting. Before, the practice signed 4 new engagement letters per month from the web. Nine months after launch, it signs 6 (+50 %). With average annual fees of EUR 2,400 per new client, the 2 extra letters per month represent EUR 57,600 of recurring annual fees over 12 months. On the production side, the client area removes around 6 hours of chasing and email sorting per week, close to 280 hours a year. Payback is reached in under 5 months.
FAQ
How much does an accountant's website cost in 2026?
Budget EUR 6,500 to 11,000 excl. VAT for a premium brochure site of 15 to 25 pages and EUR 14,000 to 22,000 with a secure client area. Vendor offers start at EUR 89 per month but offer little customisation.
Must the client area be hosted in the EU?
It is not a strict legal requirement, but EU hosting simplifies GDPR compliance and reassures clients. The extra cost is small: EUR 25 to 60 per month.
Can the client area connect to the practice's accounting software?
Yes, if the software offers a documented API. That integration pushes the budget beyond EUR 22,000 and extends the project to 14-20 weeks.
Should fees be shown on the website?
An indicative grid (for example "from EUR 120 per month for a sole trader") filters enquiries and improves the signing rate. Practices that publish one often get better-qualified meetings.
How fast does the site deliver results?
The first local SEO effects show after 3 to 4 months. A realistic target is 30 to 60 % more engagement letter requests at 9 months, depending on local competition.
