PCI DSS for Software Companies: A Complete Step-by-Step Guide

If your software company handles, processes, stores, or transmits payment card data — or if you build products that do — you need to understand PCI DSS compliance. Getting certified can feel overwhelming, but breaking it down into manageable steps makes the process far more approachable. This guide walks you through exactly what PCI DSS is, why it matters for software companies specifically, and how to achieve compliance efficiently.

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

The Payment Card Industry Data Security Standard (PCI DSS) is a set of security requirements established by the PCI Security Standards Council (PCI SSC). It was created by major card brands — Visa, Mastercard, American Express, Discover, and JCB — to protect cardholder data and reduce fraud.

For software companies, PCI DSS matters for several critical reasons:

You may be a “service provider” if your software touches cardholder data environments (CDEs)
Your clients may require it as a contractual condition before signing
Non-compliance can result in fines, card brand penalties, or loss of the ability to process payments
A data breach without compliance can expose you to significant legal and financial liability

Even if your software doesn’t directly store card numbers, if it integrates with payment systems, you likely fall within scope.

Understanding Your PCI DSS Scope as a Software Company

Before you can achieve compliance, you need to understand what’s in scope. This is one of the most important — and most misunderstood — steps.

What “In Scope” Means

Your PCI DSS scope includes any system, network, or component that:

Stores, processes, or transmits cardholder data
Could impact the security of cardholder data if compromised
Is connected to systems that handle cardholder data

Common Scope Scenarios for Software Companies

SaaS payment platforms — directly in scope if handling card data
E-commerce plugins or integrations — likely in scope depending on data flow
Point-of-sale (POS) software — in scope and subject to specific requirements
APIs that connect to payment processors — may be in scope depending on what data passes through

Pro tip: Use tokenization and point-to-point encryption (P2PE) to significantly reduce your scope. If your software never actually sees raw card data, your compliance burden shrinks dramatically.

Determining Your Merchant or Service Provider Level

PCI DSS compliance requirements vary based on your transaction volume and role in the payment ecosystem.

Merchant Levels

Level	Annual Transactions	Requirement
Level 1	Over 6 million	On-site audit by Qualified Security Assessor (QSA)
Level 2	1–6 million	Self-Assessment Questionnaire (SAQ) + quarterly scans
Level 3	20,000–1 million	SAQ + quarterly scans
Level 4	Under 20,000	SAQ + quarterly scans

Service Provider Levels

If your software company is a service provider (storing, processing, or transmitting cardholder data on behalf of clients), you fall into one of two levels:

Level 1: Over 300,000 transactions annually — requires a QSA audit
Level 2: Under 300,000 transactions annually — SAQ may suffice

Contact your acquiring bank or the relevant card brands to confirm your exact level requirements.

Step-by-Step: How to Get PCI DSS Compliance

Step 1: Perform a Gap Analysis

Start by comparing your current security posture against PCI DSS requirements (currently version 4.0). Identify where you fall short across all 12 requirement areas:

Install and maintain network security controls
Apply secure configurations to all system components
Protect stored account data
Protect cardholder data with strong cryptography during transmission
Protect all systems against malware
Develop and maintain secure systems and software
Restrict access to system components by business need
Identify users and authenticate access
Restrict physical access to cardholder data
Log and monitor all access to network resources and cardholder data
Test security of systems and networks regularly
Support information security with organizational policies and programs

Step 2: Define and Reduce Your Scope

Work with a QSA or internal security team to map your data flows and identify every system that touches cardholder data. Then actively work to reduce scope by:

Implementing tokenization through a compliant payment processor
Segmenting your network to isolate the CDE
Using hosted payment pages (iframes) managed by a PCI-compliant vendor

Step 3: Remediate Security Gaps

Address every gap identified in your analysis. This typically involves:

Technical controls: Firewalls, encryption, multi-factor authentication (MFA), intrusion detection
Process changes: Access control reviews, patch management procedures, incident response planning
Documentation: Policies, procedures, and evidence of compliance activities

Step 4: Implement Required Documentation

PCI DSS is heavily documentation-driven. You’ll need:

Information security policy
Acceptable use policy
Access control policy
Incident response plan
Vulnerability management policy
Change management procedures
Vendor management policy

This is where many software companies get stuck — creating all of this documentation from scratch is time-consuming and requires compliance expertise.

Step 5: Conduct Required Testing

Before your formal assessment, you must complete:

Quarterly vulnerability scans by an Approved Scanning Vendor (ASV)
Annual penetration testing covering both network and application layers
Internal vulnerability scans after significant changes

Step 6: Complete Your SAQ or Formal Audit

Depending on your level:

SAQ (Self-Assessment Questionnaire): Choose the correct SAQ type for your environment (SAQ A, SAQ A-EP, SAQ D, etc.) and complete it honestly with supporting evidence
Report on Compliance (ROC): Required for Level 1 merchants/service providers; conducted by a QSA who will review your controls and produce a formal report

Step 7: Submit Your Attestation of Compliance (AOC)

Once your SAQ or ROC is complete, submit your Attestation of Compliance to your acquiring bank or the card brands as required. This formally demonstrates your compliant status.

PCI DSS v4.0: What Software Companies Need to Know

PCI DSS version 4.0 became the only active standard in March 2024. Key changes that affect software companies include:

Stronger authentication requirements — MFA is now required for all access into the CDE
Customized approach — Companies can now implement alternative controls that meet the intent of requirements
Enhanced e-commerce security — New requirements for managing scripts on payment pages
Targeted risk analysis — Some requirements now require a formal risk analysis to determine frequency

Make sure your compliance program is built around v4.0, not the older v3.2.1.

Common Mistakes Software Companies Make

Avoid these pitfalls that delay or derail compliance efforts:

Assuming you’re out of scope when you’re actually not
Skipping network segmentation and inadvertently expanding your CDE
Underestimating documentation requirements — auditors want evidence, not just assertions
Treating compliance as a one-time event rather than an ongoing program
Not training employees on security awareness and cardholder data handling

How Long Does PCI DSS Take for a Software Company?

Timeline varies based on your starting point:

Well-prepared companies: 3–6 months
Companies starting from scratch: 6–12 months
Complex environments or Level 1 audits: 12–18 months

The biggest time sink is almost always documentation and evidence collection. Having pre-built, audit-ready templates dramatically compresses this timeline.

Frequently Asked Questions

Do I need PCI DSS if I use Stripe or another payment processor?

Possibly. If you use a hosted payment page and never touch card data, your scope may be minimal (SAQ A). However, if your software transmits card data before it reaches the processor, you likely have broader requirements. Always confirm with your acquiring bank.

What is the difference between a QSA and an ISA?

A Qualified Security Assessor (QSA) is an external company certified by the PCI SSC to conduct formal PCI audits. An Internal Security Assessor (ISA) is an employee of your organization who has been trained and certified to perform internal assessments. Level 1 requirements typically mandate a QSA.

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

Costs vary widely. A Level 4 merchant completing an SAQ may spend $5,000–$20,000 including scanning and remediation. A Level 1 formal audit can cost $50,000–$200,000 or more when including the QSA, penetration testing, and remediation work. Documentation and policy development add additional costs unless you use pre-built templates.

Can my software company be PCI DSS compliant if we use AWS or Azure?

Yes. Cloud providers like AWS and Azure have their own PCI DSS compliance certifications, but your responsibility doesn’t disappear. You and your cloud provider share responsibility under a shared responsibility model. You’re still responsible for your application, access controls, and data handling practices.

What happens if we fail a PCI DSS audit?

A failed audit means you’re issued a non-compliance finding. You’ll need to remediate the gaps and be re-assessed. Prolonged non-compliance can result in fines from card brands ($5,000–$100,000 per month), increased transaction fees, or termination of your merchant account.
