Web Accessibility for SaaS: Compliance Guide

SaaS Accessibility Is a Revenue Problem

For SaaS companies, accessibility is not just a compliance issue — it is a sales issue. When your product cannot pass a procurement accessibility review, you lose the deal. No negotiation, no workaround, no exception.

Government agencies at all levels require Section 508 conformance. Enterprise buyers increasingly include accessibility in vendor evaluations. The EU’s European Accessibility Act makes accessibility a legal requirement for digital products sold in Europe starting June 2025.

SaaS companies that treat accessibility as a feature rather than an afterthought win deals their competitors cannot.

The VPAT Problem

VPATs are the gatekeepers of government and enterprise SaaS sales. A government agency purchasing software must verify Section 508 conformance, and the standard way to do that is requesting the vendor’s VPAT.

Here is where most SaaS companies stumble:

No VPAT at all — the prospect asks for one, you do not have one, and the deal stalls or dies. Creating a VPAT from scratch on a product with no accessibility investment requires a full audit and remediation cycle that takes months.

Outdated VPAT — a VPAT from two years ago does not reflect your current product. Procurement teams know this. An outdated VPAT signals that accessibility is not an ongoing priority.

VPAT full of “Does Not Support” — a VPAT that honestly documents significant non-conformance is better than no VPAT, but it highlights every gap. Government buyers may accept a remediation roadmap, but enterprise buyers typically have alternatives with better conformance.

The fix is not creating a VPAT at the last minute. It is building accessibility into your development process so your product is conformant before the procurement question comes up.

Where SaaS Products Fail

Single-Page Applications

Most modern SaaS products are built as SPAs (React, Angular, Vue). SPAs introduce accessibility challenges that traditional multi-page sites do not have:

Route changes — client-side navigation changes the view without a full page load. Screen readers do not announce the change unless you explicitly manage focus and announce the new page title.

Dynamic content — dashboard widgets, notifications, and data updates that appear without page reload need ARIA live regions to be announced to screen readers.

Complex components — data grids, drag-and-drop interfaces, rich text editors, and date pickers need extensive keyboard navigation and ARIA implementation.

Data-Heavy Interfaces

SaaS dashboards display data in tables, charts, and grids. Common accessibility failures:

• Data tables without proper header markup
• Charts and graphs with no text alternative
• Sortable columns that do not announce sort state changes
• Pagination controls that are not keyboard-accessible
• Filter interfaces that update results without announcing changes

Multi-Tenant Considerations

SaaS products serve multiple customers through a single codebase. This means accessibility issues affect all customers simultaneously, and accessibility improvements benefit all customers simultaneously. Investing in accessibility at the platform level scales across your entire customer base.

Building Accessibility into the Development Process

Retroactive remediation is expensive. A SaaS product with years of accumulated accessibility debt can require months of dedicated work to reach WCAG 2.1 AA conformance. Building accessibility in from the start costs a fraction of that.

The practical approach:

1. Add accessibility linting — eslint-plugin-jsx-a11y catches common issues at compile time
2. Add automated testing — axe-core in your component tests and end-to-end tests catches issues before merging
3. Add production monitoring — A11yProof scheduled scans catch regressions from deployments, content changes, and third-party integrations
4. Generate VPATs from scan data — regular scanning gives you the conformance data to maintain current VPATs

This is not a one-time project. Every sprint, every feature, every deployment can introduce new accessibility issues. Continuous scanning is what keeps your product conformant and your VPATs current.

What SaaS Companies Need from Accessibility Tools

Effective accessibility scanning for SaaS products requires:

• SPA support — full JavaScript rendering before testing
• Authenticated testing — scanning your actual product behind login, not just the marketing site
• Component-level testing — integration with your test framework for CI/CD
• Reporting for procurement — scan results that feed into VPAT creation
• Ongoing monitoring — scheduled scans that catch regressions between releases

A11yProof handles SPA rendering, authenticated page scanning, and generates reports suitable for VPAT documentation. Starting at $29/month for a single product domain, or $199/month for agency-level scanning across multiple products.
