The verdict in three sentences
A website redesign for an accounting firm in Dublin costs EUR 6,500 to EUR 16,000 in 2026, excluding a secure client portal (quoted separately at EUR 4,000-9,000). The real B2B differentiator isn't design but the online booking rate, targeted between 12 and 18 %. GDPR compliance isn't optional: it governs the lawful collection of prospect data.
Template or bespoke: the real trade-off
An accounting firm sells trust and availability. The site must reassure and convert into meetings. Here's the 2026 costed comparison of the two approaches.
| Criterion | Dressed-up template | Bespoke redesign |
|---|---|---|
| Initial cost (EUR) | 2,500 - 4,500 | 6,500 - 16,000 |
| Timeline | 3 - 5 weeks | 7 - 11 weeks |
| Online booking | Basic | Optimised, target 12-18 % |
| Differentiation | Low | High |
| GDPR compliance | To verify | Built into the quote |
| Lifespan | 2 - 3 years | 4 - 5 years |
The secure client portal is the line item that tips a firm toward bespoke. Here is its 2026 pricing.
| Client portal feature | 2026 range (EUR) |
|---|---|
| Secure authentication | 1,200 - 2,500 |
| Document upload / sharing | 1,500 - 3,500 |
| Notifications and reminders | 600 - 1,500 |
| GDPR audit log | 700 - 1,500 |
| Portal total | 4,000 - 9,000 |
Recurring costs and compliance
An accounting firm's maintenance retainer runs EUR 200-400/month: it covers security updates, essential on a site handling tax data. GDPR compliance requires a lawful basis for processing, an up-to-date privacy policy and a records register. These must be written into the quote to avoid a hidden cost.

Mini case study
Ciara, finance director at an accounting firm in Dublin (11 staff). Her current site offers no online booking; prospects call or drop off. From 1,500 qualified monthly visitors, only 15 complete the form (1 %). She invests EUR 12,500 (redesign + booking module) and targets a 15 % booking rate. On 1,500 visitors that theoretically means 225 interactions, part of which convert into 20 qualified meetings/month. With an average annual value of EUR 3,200 per new client and a 20 % win rate, 4 new clients/month generate ~EUR 12,800 of additional monthly recurring revenue. ROI is reached in under two months.
FAQ
How much is the redesign alone, without a portal? Between EUR 6,500 and EUR 16,000 in 2026, depending on page count, design quality and content depth (service pages, tax news).
Is a secure client portal worth it? Yes for a firm exchanging many documents. At EUR 4,000-9,000 it cuts email back-and-forth and improves retention; it pays back in saved admin hours.
What booking rate should I target? A realistic goal is 12 to 18 % of qualified visitors, thanks to a visible booking button, an embedded calendar and strong reassurance.
How do I ensure GDPR compliance? By writing into the quote the lawful basis for processing, a privacy policy, explicit consent and EU hosting. It's essential from the very first form submission.
What maintenance budget should I plan? Allow EUR 200-400/month, higher if a secure client portal must be maintained and audited regularly.
