Summary

PCI DSS requires documented policies for virtually every control area. This includes: PCI DSS requires annual security awareness training for all personnel. Software developers should receive additional training specific to secure coding practices. Consequences can include fines from card brands ($5,000–$100,000 per month), increased transaction fees, mandatory forensic investigations following a breach, and in severe cases, loss of the ability to process card payments.

PCI DSS Guide for Software Companies: What You Need to Know

If your software company handles, processes, stores, or transmits payment card data — even indirectly — you almost certainly have PCI DSS obligations. The Payment Card Industry Data Security Standard (PCI DSS) is a globally recognized framework designed to protect cardholder data, and non-compliance can result in fines, reputational damage, and loss of payment processing privileges.

This guide breaks down what PCI DSS means for software companies specifically, how to determine your scope, and the practical steps you need to take to achieve and maintain compliance.

What Is PCI DSS and Why Does It Matter for Software Companies?

PCI DSS is a set of security standards created by the PCI Security Standards Council (PCI SSC), which includes major card brands like Visa, Mastercard, American Express, and Discover. The current version, PCI DSS v4.0, was released in 2022 and became the sole active standard in March 2024.

For software companies, PCI DSS matters because:

• SaaS platforms that process subscription payments or e-commerce transactions touch cardholder data
• Payment software vendors building applications that integrate with payment systems must meet specific software security standards
• B2B software companies whose platforms facilitate transactions on behalf of clients inherit compliance responsibilities
• Developers and ISVs (Independent Software Vendors) creating payment-related features are subject to the PA-DSS successor framework, now called the PCI Secure Software Standard

Even if you outsource payment processing to a third-party gateway like Stripe or Braintree, you are not automatically exempt from PCI DSS. Your compliance scope depends on how your software interacts with that data.

Determining Your PCI DSS Scope

One of the most important — and misunderstood — steps for software companies is correctly defining their cardholder data environment (CDE). Your CDE includes all systems, people, and processes that store, process, or transmit cardholder data, plus anything connected to those systems.

How Scope Affects Your Compliance Level

PCI DSS defines four merchant levels based on annual transaction volume:

Most early-stage software companies fall into Level 3 or Level 4, which means completing the appropriate Self-Assessment Questionnaire (SAQ) rather than a full external audit.

Reducing Your Scope Through Tokenization and Outsourcing

The single most effective way to reduce your PCI DSS burden as a software company is to minimize contact with raw cardholder data. Strategies include:

• Using a compliant payment gateway (Stripe, Braintree, Square) that handles card data directly
• Implementing tokenization so your systems only ever see tokens, not actual card numbers
• Hosted payment pages that redirect users to a PCI-compliant environment for data entry
• iFrame integrations that keep card data entry within the processor’s environment

When implemented correctly, these approaches can qualify you for the SAQ A — the simplest self-assessment form, with only 22 requirements — rather than the more demanding SAQ D with over 200 controls.

The 12 PCI DSS Requirements: A Software Company Perspective

PCI DSS v4.0 organizes its controls into 12 core requirements. Here’s how each applies to a typical software company:

1. Install and maintain network security controls — Configure firewalls and network segmentation to isolate your CDE
2. Apply secure configurations to all system components — Harden servers, disable unnecessary services, change default credentials
3. Protect stored account data — Avoid storing sensitive authentication data; encrypt any stored PANs
4. Protect cardholder data with strong cryptography during transmission — Enforce TLS 1.2+ across all data transmission
5. Protect all systems against malware — Deploy anti-malware solutions and keep them updated
6. Develop and maintain secure systems and software — Implement a secure software development lifecycle (SSDLC)
7. Restrict access to system components and cardholder data by business need to know — Apply least-privilege access controls
8. Identify users and authenticate access to system components — Enforce MFA, strong passwords, and unique user IDs
9. Restrict physical access to cardholder data — Control physical access to servers and data centers
10. Log and monitor all access to system components and cardholder data — Implement centralized logging and alerting
11. Test security of systems and networks regularly — Conduct vulnerability scans and penetration testing
12. Support information security with organizational policies and programs — Maintain a formal information security policy

For software companies, Requirements 6 and 8 are often the most impactful. Secure coding practices, code reviews, dependency management, and multi-factor authentication are areas where software teams typically need the most documentation and process improvement.

Building a PCI DSS Compliance Program for Your Software Company

Step 1: Conduct a Gap Assessment

Before writing a single policy, understand where you currently stand. A gap assessment compares your existing controls against PCI DSS requirements and identifies what’s missing or insufficient.

Step 2: Define Scope and Reduce It Where Possible

Work with your engineering and product teams to map data flows and identify every touchpoint with cardholder data. Then actively work to reduce that scope using the strategies mentioned above.

Step 3: Develop Required Policies and Procedures

PCI DSS requires documented policies for virtually every control area. This includes:

• Information Security Policy
• Access Control Policy
• Incident Response Plan
• Change Management Procedures
• Vulnerability Management Policy
• Acceptable Use Policy
• Vendor Management Policy

These documents are not optional — they are auditable artifacts that assessors will review.

Step 4: Implement Technical Controls

Deploy the technical controls required by your applicable SAQ or audit level. Prioritize encryption, access controls, logging, and secure development practices.

Step 5: Train Your Team

PCI DSS requires annual security awareness training for all personnel. Software developers should receive additional training specific to secure coding practices.

Step 6: Complete Your SAQ or Schedule Your QSA Audit

Submit your Self-Assessment Questionnaire to your acquiring bank or payment processor. If you’re Level 1, engage a Qualified Security Assessor for your Report on Compliance (ROC).

Step 7: Maintain Compliance Continuously

PCI DSS is not a one-time checkbox. Build compliance into your ongoing operations through quarterly vulnerability scans, annual penetration tests, policy reviews, and continuous monitoring.

Common PCI DSS Mistakes Software Companies Make

• Assuming a payment gateway makes you fully exempt — You still need to complete an SAQ and maintain basic controls
• Scoping too narrowly — Forgetting to include connected systems and third-party integrations in your CDE
• Neglecting documentation — Having controls in place but no written policies to prove it
• Skipping penetration testing — Many software companies delay this due to cost, but it’s a required control
• Not reviewing third-party vendors — All service providers with access to your CDE must also be PCI DSS compliant

FAQ: PCI DSS for Software Companies

Does my software company need PCI DSS compliance if we use Stripe?

Yes, but your scope may be significantly reduced. If you use Stripe’s hosted payment pages or Stripe.js, you likely qualify for SAQ A, which has minimal requirements. However, you still need to complete the SAQ and maintain basic security practices.

What is the difference between PCI DSS and PA-DSS?

PA-DSS (Payment Application Data Security Standard) was the standard for payment software vendors. It was retired in 2022 and replaced by the PCI Secure Software Standard, which applies to software vendors building payment applications sold to merchants.

How much does PCI DSS compliance cost for a software company?

Costs vary widely. For Level 4 merchants using a simplified SAQ A approach, compliance costs may be minimal — primarily staff time and any tooling. Level 1 compliance with a full QSA audit can cost $50,000–$200,000+ annually, including remediation, audits, and ongoing monitoring.

How long does it take to achieve PCI DSS compliance?

For a software company starting from scratch, expect 3–6 months for Level 3–4 compliance and 6–18 months for Level 1. The timeline depends heavily on your current security posture and how much remediation is needed.

What happens if my software company fails a PCI DSS audit?

Consequences can include fines from card brands ($5,000–$100,000 per month), increased transaction fees, mandatory forensic investigations following a breach, and in severe cases, loss of the ability to process card payments.
