Accessible e-commerce – apps & web agencies: supplier annex, proof of testing and SLA | Word/PDF/Excel

Does your Shopify store use a checkout app, payment module, login, web agency, or accessibility-critical third-party features? Document what the supplier is required to deliver, what has actually been tested, what deficiencies exist, and who approves the next release. This is a focused set of contracts and evidence for consumer-facing e-commerce—not just another general accessibility policy.

What you get: five Swedish working documents, a Swedish user guide, and an English User Guide. All seven are available as editable DOCX and searchable PDF files, along with a Swedish Excel workbook with nine tabs. 15 customer files in total in a digital ZIP. The PDF files are printable but do not contain interactive form fields; use Word to fill out the templates.

Who Should Buy—and Who Should Choose the Basic Package?

For e-commerce businesses, web agencies, Shopify and app developers, and compliance, quality, and product managers collaborating on accessibility within a customer journey. Particularly useful for theme and app changes, new checkouts, payment services, CAPTCHA/2FA, or PTS requests. If you instead need an overall accessibility routine, publicly available accessibility information, a comprehensive self-assessment, or a general exemption assessment, see Mallbutik's comprehensive basic package for accessible e-commerce.

Complete File List

Excel—From App to Manual Decision

Overview: summarizes registered apps, tests, open non-conformances, supporting documentation, and actual attestations. App Register: identifies the supplier, feature, purchase journey, and control boundary. Requirements Matrix: links needs to test cases. Test Evidence: shows passed, failed, untested, and missing evidence. Non-Conformances: flags missing retesting when an issue is closed. Remediation SLA: tracks only the timeframes agreed upon by the parties themselves. Deliverables: acknowledges supporting documentation without automatically approving it. Decisions: require an attestation by a named human. Read Me: sources, limitations, and instructions.

The formulas have been tested using ten synthetic scenarios. The customer file contains no sample customers or fictitious supplier certificates. A passed test with evidence receives the signal “Technically OK—NOT a Legal Decision”; a closed non-conformance without retesting is clearly marked.

Legal Basis—with Important Limitations

The Act (2023:254) on the Accessibility of Certain Products and Services covers consumer-facing e-commerce services where the conditions of the Act are met. PTSFS 2024:6, particularly Section 8, specifies, among other things, accessibility requirements for identification, security, and payment, as well as information on the accessibility of products and services when responsible actors provide such information.

Neither the Act nor the regulations require a template named “supplier addendum.” This is a voluntary contract addendum. Responsibility for the e-commerce service cannot be contractually excluded without question. The exemption for certain third-party content must be assessed on a case-by-case basis, including whether the content is funded, developed, or controlled by the actor in question. Micro-enterprise exemptions and any other exemptions require separate assessment. Follow PTS's current supervisory guidance.

Date Clarification: the Accessibility Act has applied since 28 June 2025. The PTSFS 2026:6 amendment concerns certain product documentation in Swedish or English in market surveillance cases and is not a new requirement for e-commerce apps from 1 November 2026.

How the Documents Are Used

1. Determine whether the e-commerce service and service provider are covered by the applicable requirements.
2. Inventory critical apps and purchase journeys; define the scope of the contract.
3. Negotiate the supplier addendum with concrete, version-specific acceptance criteria.
4. Request test evidence and conduct your own manual tests using relevant assistive technologies.
5. Record errors, send non-conformance notices, and follow up against the actual agreed SLA.
6. Perform retesting after the supplier's remediation and document a separate human decision before release.

Frequently Asked Questions About Accessibility Requirements for Apps and Web Agencies

Is a Supplier's WCAG Certificate Enough?

No. A certificate or automated test may be relevant supporting documentation, but the actual scope, test environment, known deficiencies, and applicable legal requirements must be assessed.

Are All Third-Party Apps Exempt?

No. The exemption for third-party content is narrow and fact-dependent. A purchased or controlled checkout or form feature is not automatically exempt.

Can I Use the Contract Addendum as Official Regulatory Evidence?

No. It is a voluntary B2B addendum, not a form prescribed or approved by PTS.

Does the Remediation SLA Have a Legally Mandated Number of Days?

Not as a general number of days in this template. The parties must specify any contractual timeframes and assess other applicable obligations separately.

Can Excel Legally Approve an App?

No. The register tracks administrative control signals. Legal assessment and the decision of the responsible person lie outside Excel.

Are the English Templates Ready to Send as an English Contract?

No. Five working templates and the Excel file are in Swedish; the English file is a user guide. An English contract addendum must be translated, adapted, and reviewed separately.

Do the Files Work Without Internet Access?

DOCX, PDF, and Excel can be used locally in programs that support the formats. No independent verification against all program versions and operating systems has been performed.
