How to Choose the Right PDF Accessibility Vendor
A PDF can pass an automated accessibility check and still be difficult for someone using a screen reader. Tables may be read in the wrong order, forms may be difficult to navigate with a keyboard, and images may lack meaningful descriptions. Choosing the right PDF accessibility vendor means looking beyond compliance claims to how well the remediated documents work in practice. This matters for organisations managing reports, financial disclosures, educational materials, government documents and large document libraries.
This guide covers the key things to look for when evaluating a PDF accessibility service provider. These include standards expertise, remediation methods, technical capabilities, quality checks, ongoing support, and pricing.
1. Expertise in WCAG, Section 508, ADA, PDF/UA, and EAA Compliance
Why it matters: A PDF accessibility vendor needs to know which standards apply to your organisation and what they mean for your documents. The checks will depend on the document itself and the accessibility issues it contains. Ask for validation reports that show what was checked and which issues, if any, still need to be fixed.
Which accessibility standards should your vendor know
Depending on your organisation’s location and requirements, the relevant standards and regulations may include:
- WCAG 2.2 Level AA (Web Content Accessibility Guidelines)
- Section 508
- Americans with Disabilities Act (ADA)
- European Accessibility Act (EAA)
- Accessibility for Ontarians with Disabilities Act (AODA)
Questions to ask the vendor
- Which accessibility standards and versions do you assess our PDFs against?
- How do you verify conformance with the applicable requirements?
- What testing do you perform beyond automated checks?
- Can you provide validation reports showing the results and any remaining issues?
Ask for real-world examples of their compliance success. A knowledgeable provider will confidently walk you through how they tackle legal and functional accessibility in complex documents.
2. Human-Led Remediation and Automation
Why it matters: Automated tools can fix some accessibility issues, but a table with a complicated structure or a form with poorly labelled fields may still need an expert to step in. Charts and nested lists can pose similar problems. The work needs to go beyond automated checks to make sure these elements are accessible and usable with screen readers and other assistive technologies, in line with the relevant standards.
| Approach | What it involves | Where it falls short |
|---|---|---|
| Automated remediation | Software identifies and fixes certain accessibility issues, such as adding tags or detecting document structure. | It may miss contextual problems, incorrect reading order and complex content that needs human judgment. |
| Manual remediation | Accessibility specialists inspect and correct the document, including its structure and reading order. | It can take more time, particularly when large volumes of documents need remediation. |
| Hybrid remediation | Automation handles suitable tasks, while accessibility specialists review the results, correct errors and address complex content. | The outcome depends on the quality of the tools, the expertise of the reviewers and the checks performed before delivery. |
Questions to ask the vendor
- How many pages or documents can your team remediate per week or month?
- Can you handle large backlogs as well as recurring document volumes?
- What is your typical turnaround time for standard and complex PDFs?
- Can you accommodate urgent requests, and what are the associated turnaround times and charges?
- How do you handle scanned documents, multilingual content and complex layouts?
- What happens if a deadline is missed or the volume exceeds your agreed capacity?
- Can you scale your team and resources when our document requirements increase?
- Can they remediate thousands of pages within tight deadlines?
- Do they handle rich media and interactive content?
The ideal partner should offer scalable PDF accessibility solutions for both simple and highly technical content.
3. Check Whether the Vendor Can Handle Your Document Volume and Complexity
Why it matters: Handling a large volume of PDFs requires more than basic remediation capabilities. Your provider should be equipped to manage complex layouts, such as academic publications, financial reports, and legal documents, without compromising accessibility. Choosing a partner with the right expertise and capacity helps ensure consistent results, even as your document requirements grow.
| Capability | What the vendor should be able to handle |
|---|---|
| PDF tagging | Apply appropriate tags to headings, paragraphs, lists, figures and other content elements. |
| Reading order | Ensure content is presented in a logical sequence for screen reader users. |
| Alternative text | Add meaningful descriptions to informative images and figures, where needed. |
| Tables | Structure tables correctly, including header relationships and complex table layouts. |
| Forms | Make form fields identifiable, labelled and usable with assistive technology. |
| OCR and scanned PDFs | Convert scanned content into searchable text and remediate the resulting document structure. |
| Navigation | Create a logical heading hierarchy, bookmarks and working links to help users move through the document. |
Questions to ask the vendor
- How many pages or documents can your team remediate per week or month?
- Can you handle large backlogs as well as recurring document volumes?
- What is your typical turnaround time for standard and complex PDFs?
- Can you accommodate urgent requests, and what are the associated turnaround times and charges?
- How do you handle scanned documents, multilingual content and complex layouts?
- What happens if a deadline is missed or the volume exceeds your agreed capacity?
- Can you scale your team and resources when our document requirements increase?
- Can they remediate thousands of pages within tight deadlines?
- Do they handle rich media and interactive content?
The ideal partner should offer scalable PDF accessibility solutions for both simple and highly technical content.
4. Transparent QA Processes and Reporting
Why it matters: Fixing accessibility issues is one part of the job. You also need to check that the finished documents meet the required standards. Ask the provider how they check their work and what their validation reports include. These reports should show whether any issues remain and give you the records needed for audits or compliance reviews.
What should the vendor check?
The process should cover automated validation as well as manual checks of the document’s structure and usability. Tools such as PAC can help identify technical issues, while testing with screen readers such as JAWS, NVDA or VoiceOver can reveal problems that automated checks may miss. The exact tests will depend on the document and the accessibility requirements that apply.
Ask the vendor to deliver
- The remediated PDF.
- An accessibility validation report showing the checks performed and their results.
- The accessibility standard and version used for the assessment.
- A list of any remaining issues or exceptions.
- A record of the manual checks and assistive technology testing performed.
- A clear process for correcting defects identified after delivery.
If your organisation also needs a VPAT or other accessibility documentation, confirm what the vendor can provide and what the document covers. A report should make it clear what was tested, what remains unresolved and what needs further attention.
Questions to ask the vendor
- Do you use automated checkers such as PAC alongside manual testing?
- Do you test PDFs with JAWS, NVDA or VoiceOver where appropriate?
- Will you share a validation report and details of any unresolved issues?
- How do you handle defects found after delivery?
5. Look for a Partner Who can Support you Long-Term
Why it matters: PDF accessibility needs attention as documents change, new files are added, and requirements evolve. Working with a long-term partner can help organisations keep existing documents accessible and deal with new issues as they come up, without treating every update as a fresh project.
Look for a team that can help your staff create accessible documents, provide training and clear guidance, and support you when documents need updating or accessibility issues come up after delivery.
As your organisation creates and updates documents, that support can help staff keep accessibility in mind at each stage, rather than dealing with it only when a problem comes up.
Questions to ask the vendor
- Can you support ongoing remediation as our document volume grows?
- How do you handle updates to documents that have already been remediated?
- Will we have a consistent point of contact for queries and issues?
- Do you offer guidance or training to help our team prepare more accessible documents?
- What support is available if we discover an accessibility issue after delivery?
6. Compare Pricing and Total Cost
Why it matters: A lower quote may not cover everything you need. Manual testing, quality checks, and fixing issues found during review may come at an extra cost. Check what each provider includes in the quoted price and what you’ll pay for separately before making a decision.
Common PDF remediation pricing models
Vendors generally price remediation in one of three ways:
- Per page: You pay for each page remediated. The rate may change depending on how much work the page needs.
- Per document: You pay a set price for each PDF. This can work well when your documents are similar in length and complexity.
- Complexity-based: The price depends on the work involved, such as OCR, complex tables, forms, charts or mathematical content.
PDF remediation rates vary depending on the provider, document complexity, and level of testing required. Costs may be calculated per page, per document, or based on the work involved. Compare quotes carefully to understand what is included and whether additional services, such as OCR, manual testing, and quality checks, incur extra charges.
What should an itemized quote include?
Ask the vendor to break down the costs so you know what you’re paying for. The quote should cover:
- Base remediation fees and how pages are counted.
- Extra charges for scanned documents and OCR.
- Costs for complex tables, charts, forms and mathematical content.
- Manual testing and quality assurance fees.
- Volume discounts and minimum order requirements.
- Rush delivery charges.
- Rework and defect correction fees.
- Ongoing support or maintenance charges.
- Setup, platform, or licensing fees.
Watch for the cost of rework
A low quote can become expensive if testing and corrections cost extra. Your team may also have to spend time reviewing files, reporting problems and following up on fixes.
Before agreeing to the work, ask whether defect corrections are included, how long that coverage lasts and whether any limits apply. You should also know how the vendor will handle accessibility issues found after delivery.
Questions to ask the vendor
- What does the quoted price include, and what costs extra?
- How do you price documents that vary in complexity?
- Are manual testing, validation and defect corrections included?
- Do you offer volume discounts, and is there a minimum order?
- Are there extra charges for urgent delivery, ongoing support or platform access?
- Can you provide an itemised quote based on a sample of our documents?
7. Match the PDF Accessibility Vendor to Your Organisation’s Needs
Why it matters: Different organisations have different document types, accessibility requirements, and remediation needs. Choosing a vendor with relevant industry experience and the capacity to handle your content helps ensure the right approach to remediation, testing, and ongoing support.
| Organisation or requirement | What to look for in a vendor |
|---|---|
| Government and public sector | Experience with applicable accessibility requirements, clear compliance reporting and the ability to manage public-facing documents at scale. |
| Education and higher education | Experience remediating course materials, research papers, reading lists, tables and documents used by students with disabilities. |
| Finance and banking | Experience with financial reports, statements, forms and data-heavy tables, along with consistent quality checks and clear documentation. |
| Tables | Structure tables correctly, including header relationships and complex table layouts. |
| Publishing | The ability to handle complex layouts, long-form content, figures, footnotes, tables and documents produced in large volumes. |
| Confidential records | Clear data-handling practices, appropriate access controls, secure file transfer and defined policies for storing and deleting documents. |
| Large document archives | Capacity to process substantial backlogs, prioritise documents by need, manage different file types and maintain consistent quality across batches. |
8. Red Flags to Watch for When Choosing a PDF Accessibility Vendor
Why it matters: Identifying these warning signs early can help you avoid poor-quality remediation, unexpected costs, and accessibility issues that remain unresolved after delivery.
- Reliance on automated checks alone
- Vague compliance claims
- No clear QA process or validation reports
- Unrealistic volume and turnaround promises
- Unclear post-delivery support
- Low prices with hidden costs
