Why This Matters

Every business that processes, stores, or transmits credit card information must comply with Payment Card Industry Data Security Standard (PCI DSS) requirements. Non-compliance can result in hefty fines, legal issues, and loss of customer trust. More importantly, compliance helps protect your customers’ sensitive payment information and your business reputation.

Who This Guide Is For

This guide is designed for BigCommerce store owners who are new to PCI compliance, including:

Small business owners launching their first online store
Entrepreneurs transitioning from other platforms
Anyone who feels overwhelmed by PCI requirements
Business owners who want to understand compliance before hiring help

The Basics

Core Concepts Explained Simply

PCI DSS (Payment Card Industry Data Security Standard) is a set of security requirements created by major credit card companies to protect cardholder data. Think of it as a comprehensive security checklist that every business handling credit card information must follow.

BigCommerce is what’s called a “hosted solution” or “Software as a Service (SaaS)” platform. This means BigCommerce handles much of the technical infrastructure for your online store, including payment processing and data security.

Key Terminology

Cardholder Data: Credit card numbers, expiration dates, and cardholder names
SAQ (Self-Assessment Questionnaire): A validation tool to assess compliance with PCI DSS
Level 1-4 Merchants: Classifications based on annual credit card transaction volume
ASV (Approved Scanning Vendor): Companies authorized to perform external vulnerability scans
QSA (Qualified Security Assessor): Certified professionals who can validate PCI compliance

How It Relates to Your Business

When you use BigCommerce, you’re essentially partnering with them to handle payment processing. BigCommerce maintains PCI DSS Level 1 compliance, which is the highest level of certification. However, this doesn’t automatically make your store compliant – you still have responsibilities.

Your compliance requirements depend on:

How many credit card transactions you process annually
How you handle customer payment information
What additional tools or customizations you use

Why It Matters

Business Implications

PCI compliance isn’t just about avoiding penalties – it’s about building a trustworthy business. When customers enter their credit card information on your BigCommerce store, they’re trusting you to protect their data. Compliance demonstrates that you take this responsibility seriously.

Risk of Non-Compliance

The consequences of non-compliance can be severe:

Financial Penalties: Credit card companies can impose fines ranging from $5,000 to $100,000 per month until compliance is achieved.

Legal Liability: In the event of a data breach, non-compliant businesses may face lawsuits and regulatory action.

Loss of Processing Rights: Payment processors may terminate your ability to accept credit cards.

Reputation Damage: Data breaches and security incidents can permanently damage customer trust and brand reputation.

Increased Processing Costs: Non-compliant merchants often pay higher processing fees.

Benefits of Compliance

Achieving PCI compliance offers numerous advantages:

Customer Trust: Compliance badges and security certifications reassure customers that their information is safe.

Reduced Liability: Proper compliance reduces your liability in case of security incidents.

Better Processing Rates: Some payment processors offer better rates to compliant merchants.

Competitive Advantage: Security-conscious customers may choose your store over non-compliant competitors.

Peace of Mind: Knowing you’re following best practices allows you to focus on growing your business.

Step-by-Step Guide

What You Need to Get Started

Before beginning your compliance journey, gather:

Your BigCommerce store admin access
Annual credit card transaction volume estimates
List of any third-party tools integrated with your store
Contact information for your payment processor

Clear Actionable Steps

Step 1: Determine Your Merchant Level
Calculate your annual credit card transaction volume:

Level 1: 6+ million transactions annually
Level 2: 1-6 million transactions annually
Level 3: 20,000-1 million transactions annually
Level 4: Under 20,000 transactions annually

Most BigCommerce stores fall into Level 4, which has the simplest compliance requirements.

Step 2: Identify Your SAQ Type
Self-Assessment Questionnaires vary based on how you process payments:

SAQ A: For businesses that have fully outsourced payment processing (most BigCommerce stores)
SAQ A-EP: For e-commerce businesses with direct payment integration
SAQ D: For larger businesses or those with complex setups

Step 3: Complete Your SAQ
The SAQ is a detailed questionnaire about your security practices. For BigCommerce stores using standard payment processing, this typically involves:

Confirming you don’t store cardholder data
Verifying secure payment page usage
Implementing basic security measures for your admin access

Step 4: Implement Required Security Measures
Common requirements include:

Using strong passwords for admin accounts
Enabling two-factor authentication
Keeping your BigCommerce store and any apps updated
Regularly monitoring for suspicious activity

Step 5: Complete Vulnerability Scanning (if required)
Some SAQ types require quarterly external vulnerability scans by an Approved Scanning Vendor (ASV).

Step 6: Submit Compliance Documentation
Submit your completed SAQ and any required scan reports to your payment processor or acquiring bank.

Timeline Expectations

Initial Compliance: 2-4 weeks for straightforward BigCommerce setups
Complex Setups: 1-3 months for stores with multiple integrations
Ongoing Maintenance: Quarterly scans and annual SAQ updates

The timeline depends on your store’s complexity and how quickly you can implement required changes.

Common Questions Beginners Have

“Does BigCommerce’s compliance cover my store?”

BigCommerce maintains its own PCI compliance, which covers their platform infrastructure. However, you’re still responsible for your portion of the payment environment, including how you handle customer data and secure your admin access.

“I’m a small business – do I really need to worry about this?”

Yes, PCI compliance applies to all businesses that accept credit cards, regardless of size. However, smaller businesses typically have simpler requirements and can often complete compliance with minimal effort.

“What if I only sell a few products per month?”

Even low-volume merchants must comply with PCI DSS. The good news is that small businesses usually qualify for the simplest compliance path (SAQ A), which requires minimal documentation.

“How often do I need to renew compliance?”

PCI compliance is ongoing. You’ll typically need to complete an annual SAQ and may need quarterly vulnerability scans, depending on your merchant level and processing volume.

“Can I lose my BigCommerce store if I’m not compliant?”

While BigCommerce doesn’t typically suspend stores for PCI non-compliance, your payment processor might stop processing payments or impose fines until you achieve compliance.

“Is compliance expensive?”

For most BigCommerce stores, basic compliance costs are minimal. You might pay $100-500 annually for vulnerability scanning if required. The cost of non-compliance is typically much higher than the cost of compliance.

Mistakes to Avoid

Common Beginner Errors

Ignoring Compliance Completely: Some business owners assume BigCommerce’s compliance covers everything. This can lead to payment processor penalties and increased liability.

Choosing the Wrong SAQ Type: Selecting an inappropriate SAQ can result in incomplete compliance. When in doubt, consult with a compliance professional.

Storing Unnecessary Customer Data: Keeping credit card information you don’t need increases your compliance burden and security risk. Use BigCommerce’s secure payment features instead of trying to store payment data yourself.

Using Weak Admin Passwords: Simple passwords for BigCommerce admin accounts create security vulnerabilities. Always use strong, unique passwords and enable two-factor authentication.

Neglecting Third-Party Apps: Some apps and integrations can affect your compliance requirements. Review all installed apps to understand their security implications.

How to Prevent These Mistakes

Research your specific compliance requirements before starting
Document all third-party integrations and their security features
Implement strong security practices from day one
Review and update your security measures regularly
Stay informed about PCI DSS updates and changes

What to Do If You Make Them

If you discover compliance issues:
1. Address security vulnerabilities immediately
2. Review and correct your SAQ if necessary
3. Notify your payment processor of any significant changes
4. Consider hiring a compliance professional for guidance
5. Implement processes to prevent future issues
