To compare accessibility service providers, evaluate them across five criteria: audit methodology, deliverables, team credentials, pricing transparency, and post-audit support. The strongest providers conduct fully manual audits against WCAG 2.1 AA or WCAG 2.2 AA, deliver actionable reports with severity ratings, publish clear pricing, and offer remediation guidance after delivery. Scan-only providers cannot determine WCAG conformance because scans detect approximately 25% of issues. A provider that mixes automated scanning with a small manual review is not equivalent to a fully manual audit. Use the same criteria across every provider you evaluate so the comparison is apples to apples.
| Criterion | What to look for |
|---|---|
| Audit methodology | Fully manual audit against WCAG 2.1 AA or 2.2 AA, not a scan with light review |
| Deliverables | Detailed report with issue descriptions, WCAG references, severity ratings, and remediation guidance |
| Team credentials | Auditors with verifiable accessibility experience and recognized certifications |
| Pricing transparency | Published pricing or clear per-page, per-screen, or per-template structure |
| Post-audit support | Remediation guidance, validation, and ACR availability after the report is delivered |
Start with audit methodology
Methodology is the single most important factor when comparing providers. A fully manual audit is the only way to determine WCAG conformance. Scans flag approximately 25% of issues, which means a scan-based report leaves the majority of accessibility issues undetected.
Ask each provider directly: is the audit conducted entirely by a human auditor, or does it rely on automated scanning with a manual review layer? The answer separates serious providers from the rest.
Some companies blur this line. They market a “hybrid” approach but deliver mostly scan output with a few human notes. Push for specifics on hours spent per page or screen and what the auditor actually evaluated.
What should the deliverables look like?
A useful audit report identifies issues with enough detail that a developer can act on them without guessing. Look for issue descriptions, the specific WCAG success criterion referenced, the location in the code or content, and remediation guidance.
Severity ratings matter. They let your team prioritize fixes based on user impact and risk. A report with 200 flat issues and no prioritization signal forces your team to rebuild that structure themselves.
Sample reports tell you more than sales decks. Request a redacted example from each provider. Compare the depth, clarity, and organization side by side.
How do you verify team credentials?
Accessibility work depends on the auditor. Ask who will conduct your audit, what their experience is, and what certifications they hold. Recognized credentials include CPACC, WAS, CPWA, and DHS Trusted Tester.
A provider that cannot name the auditor or share credentials is a red flag. So is a provider that subcontracts the work to a rotating pool without disclosing it.
Experience with your asset type also matters. A team that audits web apps and SaaS daily will move faster on a SaaS audit than a team that mostly works on marketing websites.
Compare pricing transparency
Pricing transparency is a fast filter. Providers that publish per-page, per-screen, or per-template pricing make comparison easy. Providers that only quote after a sales call often price based on perceived budget rather than scope.
When requesting quotes, give every provider the same scope: the same number of unique pages or screens, the same WCAG version and level, and the same environments (desktop, mobile, or both). Otherwise you are comparing different audits, not different providers.
Ask what is included. Some quotes cover the audit report only. Others include a kickoff call, validation of fixes, and an ACR. The cheaper quote can become the more expensive engagement once those items are added.
Evaluate post-audit support
The audit report is the start, not the finish. Compare what each provider offers after delivery: remediation guidance, validation of fixes, user evaluation, ACR preparation, and ongoing monitoring.
A provider that hands over a report and disappears leaves your team to interpret findings alone. A provider that offers validation will re-evaluate fixed issues and confirm conformance, which is what auditors, attorneys, and procurement teams want to see.
If you need a VPAT or ACR, confirm the provider can produce one. Independently issued ACRs carry more weight in procurement than self-attested documents.
Build a comparison scorecard
Once you have the data, score each provider on the five criteria. Weight methodology and deliverables heavily. Weight pricing transparency less than the substance of the work.
A scorecard prevents the loudest sales pitch from winning. It also gives leadership a clear record of why one provider was selected over another.
What questions should I ask every provider?
Ask whether the audit is fully manual, who the auditor is and what their credentials are, what the report includes, whether severity ratings are provided, what the per-page or per-screen price is, and what support is offered after delivery. Same questions, every provider.
How long does the comparison process take?
Most teams can complete a thorough comparison in one to two weeks. Request sample reports and quotes from three to five providers, then complete a structured scoring round. Rushing this step often costs more later when a poor audit needs to be redone.
Is the cheapest provider ever the right choice?
Sometimes, if the methodology, credentials, and deliverables match what stronger providers offer. More often, low-priced quotes reflect scan-heavy work or shallow manual review. Price is a factor, but methodology and report quality decide whether the audit is usable.
Comparing accessibility service providers is less about who has the best website and more about who delivers a report your team can act on. Use the same criteria across every provider and the right choice tends to surface on its own.
