The verdict in three sentences
For a 40-person audit and statutory assurance firm in Berlin, a serious website redesign costs 12,000 to 25,000 EUR in 2026, driven by agency day rates of 850 to 1,050 EUR. Compliance with DSGVO (GDPR) and the BFSG accessibility law is no longer optional and adds real scope. The only metric that matters is the number of qualified engagement requests per quarter, not the number of pages delivered.
Why a 2017 website no longer brings in engagements
A firm website built in 2017 usually carries three handicaps: a structure that presents the firm instead of answering a CFO's questions, weak mobile performance (LCP often above 4 seconds) and no page targeting commercial-intent searches such as Wirtschaftsprüfer Berlin Mittelstand or due diligence audit for an acquisition. Statutory audits are a regulated, price-sensitive market, so growth comes from voluntary audits, transaction services and sector expertise, which sell on proof. The site has to show cases, sectors and identifiable partners.
| Observed symptom | Estimated 2026 impact | Fix in the redesign |
|---|---|---|
| Mobile LCP above 4 s | 25 to 40 % of visitors lost | Next.js, AVIF images, CDN hosting |
| A single Services page | No ranking on service-specific searches | 8 to 12 dedicated expertise pages |
| No sector pages | Prospects unsure about specialisation | 4 to 6 sector pages |
| Generic contact form | Unqualified leads | Form by engagement type (statutory, voluntary, due diligence) |
| No careers section | Recruiter fees of 20 to 30 % of annual salary | Careers area with openings and team stories |
| Outdated cookie banner | DSGVO exposure and image risk | Compliant consent manager, updated privacy policy |
2026 price grid for an audit firm redesign in Berlin
The figures below are 2026 orders of magnitude for B2B-focused agencies in Berlin. They include design, development, migration of useful content and 301 redirects. For comparison, the same 20-page scope costs 7,500 to 11,000 EUR excl. VAT in Lyon, France.
| Scope | Pages | Price (EUR, excl. VAT) | Timeline |
|---|---|---|---|
| Essential redesign | 12 to 15 pages | 9,000 to 12,000 | 6 to 8 weeks |
| Standard redesign with expertise pages | 20 pages | 12,000 to 17,000 | 8 to 10 weeks |
| Redesign with careers area | 25 pages + openings | 16,000 to 20,000 | 9 to 11 weeks |
| Full redesign with sector content | 30 to 35 pages | 20,000 to 25,000 | 10 to 12 weeks |
| BFSG accessibility audit and fixes | per site | 2,500 to 5,000 | 2 weeks |
| SEO copywriting per page (option) | per page | 250 to 450 | in parallel |
| Maintenance and security | monthly | 180 to 350 | ongoing |
A remote studio with lower day rates can deliver the standard scope for 8,000 to 12,000 EUR, provided the German copy is written or reviewed by a native professional.
What really moves engagement requests
Three elements matter more than pure design. First, decision-oriented expertise pages: statutory audit, voluntary audit, transaction services, internal control review, each with deliverables, typical timelines and the lead partner. Second, proof: number of engagements, sectors, anonymised references allowed by professional rules. Third, a short contact path: booking a call with a partner in two clicks instead of a ten-field form.
| Lever | Additional cost (EUR) | Expected effect (order of magnitude) |
|---|---|---|
| Online appointment booking | 600 to 1,200 | +20 to 35 % contacts |
| Sector pages (x5) | 2,000 to 3,500 | Qualified organic traffic x2 within 9 months |
| Audit threshold calculator | 1,500 to 2,500 | Lead magnet for growing SMEs |
| Careers area | 3,000 to 4,500 | Less reliance on recruiters |
| Tax and audit news blog | 1,000 to 2,000 | LinkedIn and newsletter visibility |

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Jonas, partner at a 40-person audit firm in Berlin, received 3 qualified engagement requests per quarter through the website. He invests 21,000 EUR in a redesign with 10 expertise pages, 5 sector pages, a careers area and a BFSG audit, plus 250 EUR per month for maintenance. Nine months after launch, the site generates 8 requests per quarter. With a 25 % win rate and an average annual fee of 15,000 EUR per engagement, the 5 extra requests bring about 1.25 additional engagements per quarter, close to 18,750 EUR in quarterly fees. Hiring two junior auditors through the careers area also saves around 20,000 EUR in recruiter fees. Payback: under two quarters.
FAQ
How long does an audit firm website redesign take?
Plan 8 to 12 weeks for 20 to 35 pages, including 2 weeks of workshops and copy validation by the partners. Partner availability is usually the bottleneck.
Does the BFSG apply to an audit firm website?
The accessibility law mainly targets consumer-facing services, but most corporate buyers now expect WCAG 2.1 AA. An audit and fixes cost 2,500 to 5,000 EUR and reduce legal and reputational risk.
Do we need to keep old URLs?
No, but every indexed old page needs a 301 redirect. On a 2017 site this typically covers 50 to 150 URLs, included in the 12,000 to 17,000 EUR standard scope.
Should the site be in English as well as German?
If you audit subsidiaries of foreign groups, yes: an English version of the 10 key pages costs 2,000 to 4,000 EUR with professional translation.
What should we budget for SEO after launch?
A monthly retainer of 900 to 2,000 EUR covers 2 to 4 pieces of content and tracking of 30 to 50 local and service keywords.
Let's scope your project. A 20 to 35 page redesign, indicative budget of 12,000 to 25,000 EUR depending on expertise pages, careers area and accessibility work, live in 8 to 12 weeks. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
