Who this guide is for:
This guide is designed for Squarespace users who are new to PCI compliance, including small business owners, entrepreneurs, and anyone who needs to understand these requirements without getting lost in technical jargon.

The Basics: Understanding PCI Compliance

What is PCI Compliance?

PCI compliance refers to following the Payment Card Industry Data Security Standard (PCI DSS)—a set of security requirements designed to protect credit card information. Think of it as a comprehensive checklist of security measures that businesses must implement when they handle, store, or transmit credit card data.

Key Terms You Need to Know

PCI DSS: The Payment Card Industry Data Security Standard—the actual security requirements
SAQ (Self-Assessment Questionnaire): A validation tool for merchants to assess their compliance with PCI DSS
Merchant: Any business that accepts credit card payments (that’s you!)
Payment Processor: The company that handles your credit card transactions
Cardholder Data: Information printed on a payment card, including the primary account number (PAN)

How Squarespace Fits Into PCI Compliance

Squarespace is what’s called a “hosted solution”—they provide both your website platform and payment processing capabilities. This setup significantly simplifies your PCI compliance requirements because Squarespace handles much of the heavy lifting related to payment security.

When you use Squarespace’s built-in commerce features and payment processing, you’re not directly handling raw credit card data on your servers. Instead, Squarespace’s secure systems manage this sensitive information, which reduces your compliance burden considerably.

Why PCI Compliance Matters for Your Squarespace Business

Business Protection

PCI compliance serves as your first line of defense against cyber threats. Data breaches can cost small businesses an average of $2.98 million per incident, according to IBM’s Cost of a Data Breach Report. For many small businesses, this could mean closure.

Legal and Financial Consequences

Non-compliance can result in:

Fines ranging from $5,000 to $100,000 per month until compliance is achieved
Increased transaction fees imposed by payment processors
Loss of ability to accept credit cards if violations persist
Legal liability if customer data is compromised

Customer Trust and Business Growth

Customers are increasingly security-conscious. Demonstrating PCI compliance shows professionalism and builds trust, which can:

Increase conversion rates
Reduce cart abandonment
Enable expansion into new markets
Provide competitive advantage over non-compliant competitors

Insurance and Risk Management

Many cyber liability insurance policies require PCI compliance. Without it, you might face higher premiums or denied claims if a breach occurs.

Step-by-Step Guide to Squarespace PCI Compliance

Step 1: Assess Your Current Setup (Week 1)

What you need:

Access to your Squarespace admin panel
List of all payment methods you accept
Documentation of any third-party integrations

Actions to take:
1. Log into your Squarespace account and review your commerce settings
2. Identify how you’re processing payments (Squarespace Payments, Stripe, PayPal, etc.)
3. List any third-party apps or integrations that might handle payment data
4. Document where customer payment information might be stored or transmitted

Step 2: Determine Your SAQ Type (Week 1-2)

Based on how you handle payments, you’ll need to complete a specific Self-Assessment Questionnaire:

Most Squarespace users fall into SAQ A or SAQ A-EP:

SAQ A: For merchants who have fully outsourced payment processing (most common for standard Squarespace setups)
SAQ A-EP: For e-commerce merchants who outsource payment processing but have some additional requirements

Step 3: Complete Your Self-Assessment Questionnaire (Week 2-3)

Timeline expectation: 1-2 weeks for first-time completion

What to do:
1. Download the appropriate SAQ from the PCI Security Standards Council website
2. Answer each question honestly based on your current practices
3. Address any “No” answers by implementing required security measures
4. Document your compliance efforts

Key areas the SAQ will cover:

Network security measures
Employee access controls
Regular security testing
Information security policies

Step 4: Implement Required Security Measures (Week 3-6)

Common requirements for Squarespace merchants:

Network Security:

Ensure your business WiFi uses WPA2 or WPA3 encryption
Install and maintain firewall protection on any computers that access payment data
Use secure passwords and two-factor authentication

Access Controls:

Limit access to cardholder data to only those who need it
Assign unique user credentials to each person with access
Regularly review and update access permissions

Regular Monitoring:

Implement logging and monitoring for all access to payment systems
Regularly review logs for suspicious activity
Maintain an inventory of all devices that could access payment data

Step 5: Submit Compliance Documentation (Week 6)

Required documents typically include:

Completed SAQ
Attestation of Compliance (AOC)
Network vulnerability scan results (if required)

Where to submit:

Your payment processor or acquiring bank
Sometimes directly to card brands, depending on your processing volume

Step 6: Maintain Ongoing Compliance (Ongoing)

PCI compliance isn’t a one-time achievement—it requires ongoing attention:

Quarterly tasks:

Review and update security procedures
Conduct vulnerability scans if required
Train new employees on security practices

Annual tasks:

Complete annual SAQ reassessment
Update and test incident response procedures
Review and update security policies

Common Questions Beginners Have

“Do I really need to worry about this if I’m using Squarespace?”

Yes, but the good news is that Squarespace significantly reduces your compliance burden. While Squarespace handles much of the payment security, you’re still responsible for certain aspects of compliance, particularly around how you handle any payment data and secure your business environment.

“What if I only process a few transactions per month?”

Transaction volume doesn’t exempt you from PCI requirements. Even if you process just one credit card transaction annually, you must maintain compliance. However, lower volume typically means simpler requirements (like SAQ A instead of more complex assessments).

“Can I just rely on Squarespace’s security?”

While Squarespace provides robust payment security, PCI compliance also covers your business practices, employee access, and any other systems that might interact with payment data. You need to ensure your entire payment ecosystem is secure.

“How do I know if I’m compliant?”

Compliance is demonstrated by completing the appropriate SAQ, implementing all required security measures, and maintaining ongoing adherence to PCI standards. Regular self-assessments and staying current with security best practices are key indicators.

“What happens if I have a data breach?”

If you experience a breach, immediately contact your payment processor, law enforcement if required, and begin incident response procedures. Having documented compliance efforts can help mitigate penalties, but the focus should be on prevention through proper compliance.

Mistakes to Avoid

Mistake 1: Assuming Squarespace Handles Everything

The problem: While Squarespace provides excellent payment security, compliance also involves your business practices, employee training, and operational security.

How to avoid it: Complete the full SAQ assessment and implement all requirements, not just payment processing security.

If you’ve made this mistake: Conduct a comprehensive review of all your business practices related to payment handling and implement missing security measures.

Mistake 2: Treating Compliance as a One-Time Task

The problem: PCI compliance requires ongoing maintenance, annual reassessments, and continuous monitoring.

How to avoid it: Set up calendar reminders for quarterly reviews and annual reassessments. Treat compliance as an ongoing business process.

If you’ve made this mistake: Establish a compliance calendar and catch up on any missed assessments or security updates.

Mistake 3: Not Training Employees

The problem: Employee mistakes are a leading cause of data breaches. Untrained staff can inadvertently compromise payment security.

How to avoid it: Implement regular security awareness training for all employees who might access payment systems or customer data.

If you’ve made this mistake: Immediately provide security training to all relevant employees and establish ongoing training programs.

Mistake 4: Ignoring Third-Party Integrations

The problem: Adding third-party apps, plugins, or services to your Squarespace site can introduce new compliance requirements or security vulnerabilities.

How to avoid it: Evaluate the PCI compliance status of any third-party services before integration and understand how they affect your compliance requirements.

If you’ve made this mistake: Audit all current third-party integrations and ensure they meet PCI requirements or remove non-compliant services.

Mistake 5: Using Weak Passwords and Access Controls

The problem: Weak passwords or shared accounts can provide easy access points for cybercriminals.

How to avoid it: Implement strong password policies, use two-factor authentication, and ensure each user has unique credentials.

If you’ve made this mistake: Immediately update all passwords, enable two-factor authentication, and create individual user accounts for each person who needs access.

Frequently Asked Questions

1. Does Squarespace automatically make me PCI compliant?

No, while Squarespace provides a secure payment processing environment that significantly reduces your compliance burden, you’re still responsible for completing the required self-assessment questionnaire and implementing security measures in your business operations. Squarespace handles the payment processing security, but you must ensure your business practices meet PCI requirements.

2. How much does PCI compliance cost for Squarespace users?

For most Squarespace merchants, basic PCI compliance can be achieved at minimal cost—primarily your time to complete the SAQ and implement required security measures. You might need to invest in security software, employee training, or professional assistance, which could range from $100 to $1,000 annually depending on your business complexity.

3. How often do I need to complete PCI compliance assessments?

You must complete PCI compliance assessments annually. However, you should also reassess whenever you make significant changes to your payment processes, add new integrations, or experience security incidents. Quarterly vulnerability scans may be required depending on your merchant level.

4. What happens if I switch from Squarespace to another platform?

If you migrate to a different e-commerce platform, you’ll need to reassess your PCI compliance requirements. The new platform may have different security capabilities and compliance responsibilities, potentially requiring a different SAQ type or additional security measures.

5. Can I accept payments on Squarespace while working toward compliance?

While it’s technically possible to process payments during your compliance journey, it’s risky and potentially violates your merchant agreement. Most payment processors require compliance before or shortly after you begin processing payments. It’s best to achieve compliance quickly rather than risk penalties or service termination.

6. Do I need compliance if I only use PayPal or other third-party payment services?

If you redirect customers to PayPal or other third-party services for payment (without collecting payment information on your site), you may qualify for the simplest compliance requirements (SAQ A). However, you still need to complete the appropriate assessment and maintain compliance with applicable requirements.

Conclusion

PCI compliance for Squarespace users doesn’t have to be overwhelming. While the requirements are serious and the consequences of non-compliance significant, the steps to achieve compliance are manageable, especially with Squarespace’s secure payment infrastructure handling much of the technical complexity.

The key to success is treating compliance as an ongoing business practice rather than a one-time hurdle. By following the step-by-step guide in this article, avoiding common mistakes, and staying committed to security best practices, you can protect your business and customers while building trust and credibility in the marketplace.

Remember that PCI compliance is ultimately about protecting your customers and your business. Every security measure you implement reduces your risk and demonstrates your commitment to responsible business practices.
