PCI Checklist for Software Platforms

PCI compliance is one of the most important security and operational requirements for software platforms that accept payments. Understanding compliance responsibilities is critical for protecting cardholder data, reducing security risks, and maintaining customer trust.

This PCI compliance checklist outlines the key requirements SaaS companies and software platforms should evaluate when accepting payments.

What is PCI Compliance?

PCI compliance refers to the Payment Card Industry Data Security Standard (PCI DSS), a global security framework designed to protect payment card data.

Organizations that store, process, or transmit card data are generally required by payment brands, acquiring institutions, and payment providers to comply with PCI DSS requirements.

For SaaS platforms, PCI requirements are often determined by how payment data is collected and processed within the payment workflow.

The more payment data that touches your environment, the larger your PCI compliance scope may become.

Why PCI Compliance Matters for Software Platforms

PCI compliance helps software companies protect sensitive payment information, reduce fraud risk, and meet payment industry security requirements.

Failure to maintain compliance can result in financial penalties, increased liability, reputational damage, and additional scrutiny from payment providers and card brands.

As embedded payments become more common, understanding PCI compliance is an important part of building secure and scalable payment experiences.

PCI Compliance Checklist for Software Platforms

1. Determine Your PCI Scope

The first step in PCI compliance is understanding your PCI scope.

PCI scope includes all systems, applications, processes, and personnel that can impact the security of cardholder data.

Questions to ask:

• Does cardholder data pass through your platform?
• Is payment information stored within your environment?
• Do your APIs transmit, process, or interact with cardholder data?
• Which employees have access to payment systems?

Reducing PCI scope is often one of the most effective ways to simplify compliance requirements and lower operational risk.

2. Evaluate How Payment Data is Collected

The way your platform collects payment information directly affects compliance obligations.

Software platforms that use embedded payments and secure payment collection methods may be able to reduce the amount of sensitive cardholder data that enters their environment.

Checklist:

• Review payment collection workflows
• Identify where cardholder data enters the payment process
• Confirm payment data is encrypted during transmission
• Avoid storing sensitive authentication data
• Document payment data flows

3. Validate PCI Compliance Requirements

Most organizations must complete a PCI Self-Assessment Questionnaire (SAQ) or undergo additional validation depending on transaction volume, payment architecture, and compliance requirements.

Checklist:

• Determine which PCI validation requirements apply
• Complete the appropriate SAQ
• Maintain compliance documentation
• Review PCI DSS requirements annually

4. Implement Access Controls and Security Policies

PCI DSS requires organizations to restrict access to systems that impact payment security.

Checklist:

• Limit access to authorized personnel
• Implement strong password policies
• Enable multi-factor authentication
• Maintain audit logs
• Review user permissions regularly

5. Monitor Risk and Security Activity

PCI compliance is an ongoing process that requires continuous monitoring of systems, security controls, and payment workflows.

Checklist:

• Monitor payment-related systems
• Review security alerts and logs
• Conduct vulnerability assessments
• Maintain incident response procedures
• Address identified risks promptly

6. Review Third-Party Payment Providers

Many SaaS platforms rely on payment companies to support onboarding, compliance, underwriting, and transaction processing. Before selecting a payments partner, it's important to verify their security practices and PCI compliance responsibilities.

Checklist:

• Confirm PCI compliance status
• Review security certifications
• Understand shared compliance responsibilities
• Maintain vendor documentation

7. Train Internal Teams

Security and compliance require ongoing collaboration across engineering, operations, product, and leadership teams.

Checklist:

• Provide PCI security awareness training
• Document compliance procedures
• Establish internal ownership
• Review policies regularly

How Embedded Payments Can Help Reduce PCI Compliance Scope

For most SaaS companies, one of the biggest advantages of embedded payments is the potential to reduce PCI compliance scope.

Modern embedded payments solutions can use tokenization, hosted payment fields, and secure payment APIs to reduce the amount of cardholder data that touches the software platform's environment.

Depending on payment architecture and implementation, this can help:

• Reduce PCI scope
• Lower compliance overhead
• Improve payment security
• Accelerate time to market
• Simplify payment operations

By limiting exposure to sensitive payment data, software companies may be able to reduce some of the operational burden associated with PCI compliance while delivering a seamless payment experience for merchants and customers.

Many software platforms work with embedded payments providers to support payment operations, security, and compliance-related responsibilities while maintaining control of the customer experience.
