Does anyone know if or how i can set up credit card protection using quickbooks online?

Welcome to the Community space, @mycomfycouches2-.

Let me share information on how you can be PCI compliant.

You must complete a Self-Assessment Questionnaire (SAQ) to become PCI compliant. The necessary SAQ is determined by how you store, manage, and process card data. Some additional requirements may include:

• External vulnerability scanning
• Internal vulnerability scanning
• Penetration testing
• Security policy implementation

After that, create an account with SecurityMetrics and purchase the PCI package that best suits your needs. For more information about PCI DSS Compliance Services, see these articles:
