What is TPGi?

This section explains what to confirm about TPGi when evaluating them against Evinced. Do not rely on marketing claims alone — validate each point with vendor documentation or a written conformance report.

• Services to verify: consultancy engagements, accessibility audits, training, long-term governance and any hosted or on-premise tooling.
• Testing and remediation: ask whether they provide automated scanning, manual expert testing, code-level remediation, or developer training as separate line items.
• Standards and evidence: request a VPAT or accessibility conformance report stating which WCAG versions and levels they assess and any regulatory coverage (for example, Section 508 or EAA — verify relevance to your market).
• What’s often missing from vendor pages: exact scan limits, how false positives are handled, and explicit lists of CI/CD or CMS integrations — ask sales or support for those details.

What is Evinced?

This section lists the same verification points for Evinced so you can compare like-for-like. Insist on documentation for automated coverage and remediation workflows.

• Services to verify: product licences, SaaS testing platform, professional services, and any managed remediation offerings.
• Testing and remediation: confirm what portion of WCAG can be covered automatically versus what they treat as manual review items and how suggested fixes are delivered to developers.
• Standards and evidence: request a VPAT or equivalent conformance report and a clear statement of which WCAG versions and levels are covered by their automation and manual services.
• What’s often missing from vendor pages: exact pricing formula, real-world coverage percentages, and whether API or CI integrations are included in each plan.

Feature comparison: testing scope, WCAG coverage, integrations and reporting

Use the same checklist for both vendors and score them on documented evidence rather than marketing language. Key features to compare:

• Automated vs manual testing: automated tools find only a subset of WCAG failures. Verify which rulesets are used (for example, axe-core or other engines) and whether the vendor provides manual expert review for keyboard, screen reader and cognitive accessibility issues.
• WCAG versions and levels: confirm the vendor’s stated support for WCAG 2.1, 2.2 or 3.0 (if claimed) and whether they claim conformance at A, AA or AAA — ask for a VPAT to substantiate claims.
• Integrations: check for CI/CD pipelines, issue trackers (Jira, Azure DevOps), CMS plugins, and developer tooling. Ask for examples or a sandbox account to test integrations.
• Reporting and governance: compare dashboard screenshots, export formats (CSV, PDF), executive summary reports and audit logs for remediation progress and historical compliance evidence.
• Remediation support: evaluate whether automated fixes, code snippets, annotated screenshots, or developer training are supplied and if remediation work can be outsourced to the vendor.

Pricing comparison

Accessibility vendors commonly use one or a combination of these pricing models: subscription (per-app or per-scan), seat-based, scan-volume tiers, and professional services billed hourly or per-project. For both TPGi and Evinced:

• Request written pricing that lists what is included in each tier (scans, seats, integrations, training hours, remediation labour).
• Ask about overage charges for additional scans or users and whether discounts exist for multi-year commitments or public-sector procurement.
• If procurement requires a statement of work, get sample SOWs and deliverable timelines to compare total cost of ownership.
• Where pricing isn’t published: ask for a detailed proposal and clarify the cost of optional services (VPAT creation, manual audits, developer support).

Ratings and user reviews

To compare customer sentiment for TPGi and Evinced:

• Check multiple review sites (G2, Capterra, TrustRadius) and note dates and review volumes; vendor reputations can change quickly, so use the most recent data.
• Look for recurring praise (e.g., quality of audits, responsiveness of support) and repeated complaints (e.g., false positives, integration friction, pricing surprises).
• Ask vendors for customer references in your sector and, if possible, speak directly to peers who use the product at scale.

Ease of use and support

Evaluate both vendors on these operational criteria by requesting a demo and trial access where possible:

• Onboarding: how long to first scan and whether vendor provides onboarding support or training workshops.
• Developer experience: availability of code-level guidance, IDE or CI integrations, and reproducible test cases for developers to fix issues quickly.
• Support: support hours, contact channels, SLA response times, and whether a named customer success manager is included.
• Accessibility of the vendor’s own product: confirm that their dashboard and documentation meet accessibility standards.

Which one is right for you?

Choose by matching vendor strengths to your primary need:

• If you need strategic consultancy and custom audits: prioritise the vendor with demonstrable professional services, long-term governance and a track record of complex audits — verify with case studies and references.
• If you need automated, developer-focused testing and fast remediation: prioritise the vendor with clear automated coverage statements, CI integrations and developer tooling — test those integrations in a trial.
• If procurement or regulation drives the choice: ask for a VPAT, legal attestation, and evidence of prior compliance work in your regulated sector.
• For mixed needs: choose the vendor that documents a hybrid approach (automation plus manual validation) and offers flexible professional services.

Verdict

Both TPGi and Evinced are names buyers search for when selecting accessibility solutions. Rather than assuming parity, evaluate both against the exact criteria above and require written evidence (VPATs, demo accounts, integration tests and customer references). Pick the provider whose documented capabilities align closest with your technical stack, regulatory needs and capacity for internal remediation.

FAQs

1. Can automated testing tools make my site fully WCAG compliant?

No. Automated scans detect many common issues but cannot verify semantic correctness, keyboard and screen reader behaviour, or some cognitive requirements—manual testing is still required.

2. What is a VPAT and why ask for one?

A VPAT (Voluntary Product Accessibility Template) or accessibility conformance report summarises how a product maps to WCAG or other standards; request it to verify vendor claims about covered WCAG versions and levels.

3. Should I prioritise price or coverage?

Prioritise documented coverage and remediation outcomes. A cheaper automated-only option can leave costly manual work later—estimate total cost of ownership including professional services.

4. How do I compare false positives between vendors?

Request sample scan exports, reproduce issues in a trial, and ask vendors how they reduce false positives (rule tuning, machine learning filters, or human verification).

5. Can vendors guarantee legal compliance?

No vendor can guarantee legal compliance for you. Vendors can provide testing, remediation and documentation to reduce legal risk, but final compliance depends on the organisation’s complete remediation and governance.

6. What contract terms should I watch for?

Check data processing terms, export rights for your data, termination fees, support SLAs, and whether security and accessibility of the vendor’s product are contractually guaranteed.
