Why Do I Have to Complete a PCI Self-Assessment Questionnaire With a Merchant Account
—but Stripe, Square or PayPal May Seem Easier?
It's a question I hear from business owners:
“Why does my merchant account ask me to complete an SAQ when I never had to do this with an aggregator?”
Here's the important part:
Using an aggregator does NOT automatically eliminate your PCI DSS responsibilities.
The Self-Assessment Questionnaire (SAQ) is one method eligible merchants use to validate that they're following the PCI DSS security requirements applicable to the way they accept payments.
Why Does a Traditional Merchant Account Ask for It?
Your account is individually underwritten.
Your processor/acquirer may require you to validate PCI compliance directly.
Your payment environment matters.
In-store terminals, virtual terminals, e-commerce, stored card data and other acceptance methods can result in different PCI requirements and SAQ types.
It's about identifying vulnerabilities.
The process can help uncover security practices that need attention before they become expensive problems.
What About Stripe, Square & PayPal?
Aggregators can simplify portions of PCI compliance because much of the payment infrastructure may be handled within their controlled environments.
But “simplified” doesn't mean “exempt.”
Your responsibilities depend on how your business accepts, handles, stores and transmits cardholder data.
Think of the SAQ Differently
Don't look at it as:
“Why is my processor making me do more paperwork?”
Look at it as:
“What am I doing to make sure my customers' payment data—and my business—are protected?”
The Bottom Line
PCI compliance isn't about who processes your payments.
It's about protecting the payment environment.
Whether you use a traditional merchant account or an aggregator, don't assume PCI security is somebody else's responsibility.
Protect the cardholder.
Protect your merchant account.
Protect your business.
