The verdict in three sentences
For a B2B web app, a WCAG 2.2 AA audit of 15 representative screens costs, as a 2026 market ballpark, EUR 5,000 to 11,000 in Amsterdam, and remediation typically adds EUR 12,000 to 45,000 depending on technical debt. The European Accessibility Act has applied since 28 June 2025, but it mainly targets products and services offered to consumers, so many pure B2B tools fall outside its direct scope. The pressure on B2B vendors comes from public sector buyers and enterprise procurement, which increasingly require an accessibility statement and a conformance report against EN 301 549.
Does the EAA actually apply to your app?
The EAA (Directive (EU) 2019/882) lists specific consumer services: e-commerce, banking, e-books, passenger transport, electronic communications and a few others. The Netherlands transposed it into national law, with market surveillance handled by designated Dutch authorities. If your platform sells to consumers, even partly, it is likely in scope. If it is a back-office tool sold only to businesses, the direct obligation is weaker, but two forces still push you to comply.
First, Dutch public bodies are bound by the Web Accessibility Directive and buy software that meets the same standard, so tenders ask for a statement and an Accessibility Conformance Report. Second, large enterprise customers now add accessibility clauses to their vendor questionnaires. Penalties under the Dutch EAA implementation are set nationally; check the official text on wetten.overheid.nl rather than relying on figures quoted in blog posts.
| Situation | EAA direct obligation | Practical pressure | Priority |
|---|---|---|---|
| Consumer-facing booking or checkout | Likely in scope | Regulator and consumers | High |
| B2B SaaS sold to Dutch municipalities | Usually indirect | Public tenders | High |
| B2B SaaS sold to banks or insurers | Indirect | Vendor due diligence | Medium to high |
| Internal tool, no external users | Out of scope | Employee inclusion | Medium |
| Microenterprise providing services | Exemption may apply | Customer demand | Case by case |
Audit and remediation budget
B2B apps concentrate the hardest components: sortable data tables, long forms with validation, modal dialogs, custom dropdowns, charts and drag-and-drop. WCAG 2.2 added criteria that often catch older apps, such as minimum target size and alternatives to dragging movements.
| Work package | Scope | Timeline | 2026 market ballpark |
|---|---|---|---|
| Quick scan | Automated tools plus 5 screens | 1 week | EUR 2,000 to 3,500 |
| Full WCAG 2.2 AA audit | 15 screens, manual testing | 2 to 3 weeks | EUR 5,000 to 11,000 |
| Design system remediation | Components, focus, contrast tokens | 3 to 6 weeks | EUR 7,000 to 20,000 |
| Screen-level fixes | Forms, tables, dialogs | 3 to 8 weeks | EUR 5,000 to 25,000 |
| Retest and ACR (VPAT based) | Conformance report for tenders | 1 to 2 weeks | EUR 2,000 to 4,500 |
| Accessibility statement | Published page and roadmap | 2 to 3 days | EUR 800 to 1,500 |
The winning approach is to fix the component library first: a corrected button, input or dialog propagates everywhere. Apps built on a shared design system usually land near the low end of the remediation range; apps with duplicated UI code land near the high end. If you are rebuilding parts of the product anyway, Kolonell's prices for a medium-complexity custom application run EUR 6,100 to 10,670 (4,000,000 to 7,000,000 FCFA), with accessibility designed in rather than retrofitted.
Mini case study
Illustrative example: Sanne, head of product at an Amsterdam SaaS vendor selling permit management software to Dutch municipalities. Audit of 15 screens: EUR 8,000, initial conformance around 45 % of applicable criteria. Remediation: EUR 16,000 on the design system and EUR 10,000 on screens, then EUR 3,500 for retest and the conformance report. Total: EUR 37,500 over 4 months, reaching about 90 % with a documented roadmap for the rest.
Sanne answers around 8 municipal tenders a year with an average contract value of EUR 60,000 a year. Losing a single tender for missing accessibility documentation would cost more than the entire programme in year one.

FAQ
How much does a WCAG 2.2 AA audit cost in Amsterdam?
As a 2026 market ballpark, EUR 5,000 to 11,000 for 15 representative screens. A quick scan at EUR 2,000 to 3,500 helps size remediation first.
Is my B2B app covered by the European Accessibility Act?
Pure B2B tools are often outside direct scope, since the EAA targets listed consumer services. However, public tenders and enterprise buyers in the Netherlands increasingly require WCAG conformance, so the commercial deadline is often earlier than any legal one.
What is an ACR and do I need one?
An Accessibility Conformance Report, often built on the VPAT template, documents conformance criterion by criterion. Expect EUR 2,000 to 4,500 with retesting; procurement teams frequently ask for it.
Can automated tools replace a manual audit?
No. As a commonly cited estimate, they catch around 30 to 40 % of issues; keyboard behaviour, screen reader output and meaningful labels need manual testing.
How long does remediation take?
Usually 6 to 14 weeks. Fixing shared components first can cut the budget by around 30 % compared with screen-by-screen fixes.
