Terms of Service

Last Updated: May 2026

1. Acceptance of Terms

These Terms of Service ("Terms") govern access to and use of the QA Stack platform, associated applications, APIs, integrations, documentation, and related services (collectively, the "Services") provided by QA Stack ("Company," "we," "our," or "us"). By accessing, evaluating, subscribing to, implementing, or otherwise using the customer, organization, or authorized user (collectively, "Customer" or "you") acknowledges and agrees to be bound by these Terms.

If you are entering into these Terms on behalf of an organization, you represent and warrant that you possess the requisite authority to bind such organization.

2. Enterprise Platform Nature

The Services constitute configurable enterprise software tools intended to assist Customers in managing operational, quality, compliance, manufacturing, documentation, and workflow-related activities. The Services are not intended to replace independent operational judgment, regulatory review, internal validation procedures, qualified personnel oversight, or legally mandated compliance obligations.

Customer acknowledges and agrees that:

  • operational decisions remain solely Customer’s responsibility;
  • regulatory compliance obligations remain solely Customer’s responsibility;
  • Customer is solely responsible for validation, verification, implementation review, workflow configuration, approval procedures, and production deployment decisions;
  • Customer assumes full responsibility for evaluating whether the Services are suitable for its intended operational, regulatory, manufacturing, or compliance use cases.

3. Customer Evaluation and Independent Verification

Customer expressly acknowledges that prior to purchasing, deploying, integrating, relying upon, or operationalizing the Services, Customer has had adequate opportunity to:

  • independently evaluate the functionality, performance, suitability, and operational compatibility of the Services;
  • conduct internal testing, sandbox validation, pilot deployments, verification procedures, and regulatory assessments;
  • review technical documentation, workflows, outputs, integrations, automation behavior, and data handling processes;
  • consult legal, compliance, validation, quality assurance, cybersecurity, manufacturing, and technical advisors as deemed necessary.

Customer further acknowledges that enterprise software implementations inherently involve operational, technical, integration, configuration, deployment, migration, data quality, workflow, and human-process risks.

Accordingly, Customer assumes sole responsibility for all decisions made in reliance upon or connection with the Services.

4. No Warranty

QA Stack does not warrant that:

  • the Services will meet Customer requirements;
  • workflows will operate without interruption or misconfiguration;
  • outputs will be complete, accurate, or suitable for regulatory reliance;
  • the Services will prevent operational losses, compliance failures, manufacturing deviations, or audit findings;
  • integrations with third-party systems will remain continuously available or error-free.
