What a VPAT is and why it matters

A VPAT (Voluntary Product Accessibility Template) is a standardised document describing how your product conforms to accessibility standards like Section 508, WCAG, or EN 301 549. Buyers use it to evaluate vendors during procurement. Federal procurement requires it. Over 50% of enterprise buyers request one before evaluating a product on its merits. A missing or inaccurate VPAT can disqualify you before your product is even reviewed. Zylyn produces VPATs backed by real testing — every conformance claim is defensible because it's grounded in evidence, not self-assessment.

  • Section 508 (WCAG 2.0 AA) VPATs
  • WCAG 2.1 AA and WCAG 2.2 AA ACRs
  • EN 301 549 conformance documentation
  • Gap analysis and remediation guidance
  • Updated documentation as your product evolves
  • Evidence-backed claims — no unsupported assertions

Frequently asked questions

Common questions about documentation services.

A Voluntary Product Accessibility Template — a standardised document produced using the VPAT framework that describes how your product conforms to accessibility standards like Section 508, WCAG, or EN 301 549. Buyers use it to evaluate vendors during procurement.

Any time a federal agency, state government, or large enterprise asks for one as part of a procurement process. Over 50% of government and enterprise buyers request accessibility documentation before evaluating a product on its merits. A missing or weak VPAT can disqualify you before your product is even reviewed.

A VPAT is the blank template. An ACR (Accessibility Conformance Report) is the completed document — your filled-in VPAT. The terms are often used interchangeably.

Yes, but an inaccurate VPAT is worse than none. If your self-reported conformance claims are tested and found to be wrong during procurement evaluation, it damages your credibility and can expose you to contract risk. Zylyn's VPATs are backed by real test evidence so every claim is defensible.

We produce VPATs against Section 508 (WCAG 2.0 AA), WCAG 2.1 AA, WCAG 2.2 AA, and EN 301 549 — the most commonly required frameworks in US government and international procurement.

Whenever your product changes significantly — a major release, redesign, or new feature set. Zylyn offers ongoing testing and VPAT maintenance so your documentation stays current.
