Bottom Line Up Front
If you run a community on Circle.so and you just received a PCI compliance questionnaire from your payment processor, take a breath — Circle.so PCI compliance is almost certainly simpler than it looks. Circle handles your membership payments through integrated processors (typically Stripe), which means the heaviest lifting of protecting card data happens on their compliant infrastructure, not yours.
For most Circle.so creators and community businesses, this comes down to confirming you never touch raw card numbers, completing a short self-assessment questionnaire (SAQ), and — in some cases — running a quarterly scan. That’s the whole story for the majority of small merchants. Let’s walk through what the questionnaire means and exactly what you need to do.
What Is PCI Compliance (In Plain English)
PCI DSS stands for the Payment Card Industry Data Security Standard. It’s a set of security rules designed to protect credit card data anywhere it’s collected, processed, transmitted, or stored. If you accept card payments — including subscription fees and course sales through your Circle.so community — it applies to you.
The standard was created by the major card brands (Visa, Mastercard, American Express, Discover, JCB) through a body called the PCI Security Standards Council (PCI SSC). But here’s the part people miss: the PCI SSC writes the rules, while your acquiring bank (also called your acquirer) and your payment processor are the ones who actually enforce them. That’s why the questionnaire came from them, not from some central PCI office.
What happens if you ignore it? Your processor can charge non-compliance fees — often a recurring monthly surcharge. If a breach happens and you weren’t compliant, you could be on the hook for fraud liability, forensic investigation costs, and card-brand penalties. In the worst case, you can lose the ability to accept cards at all.
The good news: because Circle.so routes payments through a hosted, compliant processor, most small businesses qualify for the simplest SAQ types — the ones with the fewest requirements and, often, no scan at all.
Do You Need to Be PCI Compliant?
The simple answer: if you accept credit cards in any form, yes. Selling a $10/month community membership counts just as much as running a storefront.
Your obligations scale with your merchant level, which your acquirer assigns based on your annual card transaction volume and risk. The vast majority of Circle.so community owners fall into Level 4 — the lowest-volume, lowest-burden tier. You don’t pick your level yourself; if you’re unsure, ask your acquirer to confirm it in writing.
What does your processor expect? At minimum, an annual self-assessment confirming you handle card data responsibly. The questionnaire they sent you is that self-assessment — the SAQ (Self-Assessment Questionnaire). They sent it because card-brand rules require them to collect proof of compliance from every merchant they serve, and that includes you.
Which SAQ Do You Need?
There are several SAQ types, and the right one depends entirely on how card data flows through your business. For Circle.so creators, the answer is usually the easiest type.
Circle.so uses an integrated, hosted payment flow — when a member enters their card details, that data is captured directly by the payment processor’s secure fields, not by you or by Circle in a way that exposes raw card numbers to your systems. That hosted, fully outsourced model is the textbook case for SAQ A.
Here’s how the common scenarios map out:
| Payment Scenario | Likely SAQ | Complexity |
|---|---|---|
| Circle.so / hosted e-commerce checkout (processor captures card data) | SAQ A | Low |
| E-commerce where your page partially controls the payment fields | SAQ A-EP | Medium |
| Standalone IP-connected card terminal | SAQ B-IP | Low–Medium |
| Dial-out or imprint terminal, no electronic storage | SAQ B | Low |
| Virtual terminal — phone orders keyed into a browser | SAQ C-VT | Medium |
| Internet-connected payment systems, no card storage | SAQ C | Medium–High |
| You store card numbers anywhere (please stop) | SAQ D | High |
If you only sell through Circle.so and never see or store raw card numbers, SAQ A is almost certainly your path. If you also take card payments another way — phone orders, an in-person terminal at a live event — you may need a second SAQ for that channel.
Not sure? Our free SAQ Wizard asks a handful of plain-language questions about how you take payments and tells you exactly which questionnaire applies — no guesswork.
How to Complete Your SAQ
An SAQ is a structured checklist of yes/no questions about your security controls. SAQ A — the one most Circle.so merchants use — is the shortest type, focused mostly on confirming you’ve outsourced card handling to a compliant provider and that you protect the few things still in your control (like account access and policies).
For a typical SAQ A, expect to spend anywhere from under an hour to an afternoon, depending on how organized your documentation is. Answering “yes” to a question isn’t just ticking a box — it’s a written attestation that the control is genuinely in place. So before you answer “yes,” make sure it’s true.
Documentation and information you’ll likely want on hand:
- Confirmation that your payment processor is PCI compliant (their AOC — Attestation of Compliance — is usually downloadable from their site)
- A short information security policy covering how your business handles card data
- Your list of users with access to payment-related systems and confirmation that multi-factor authentication (MFA) protects those accounts
- Evidence you don’t store, process, or transmit raw card numbers yourself
The Quarterly ASV Scan
Some SAQ types require a quarterly ASV scan — an external vulnerability scan run by an Approved Scanning Vendor (ASV) against any internet-facing systems in scope. SAQ A merchants frequently do not need an ASV scan because there are no in-scope external systems under their control, but this depends on your exact setup. If you run your own website or server alongside Circle, a scan may apply. When in doubt, confirm with your acquirer or QSA — and if you do need one, our ASV scanning service can schedule and run it for you.
Once your SAQ is complete, you sign the accompanying AOC (Attestation of Compliance) and submit both to your acquirer or processor — usually through their compliance portal. That submission is what satisfies the questionnaire they sent you.
What It Costs
Costs vary, but for a small Circle.so merchant on SAQ A, this is one of the lower-cost compliance situations out there. Here’s a realistic picture:
| Item | When It Applies | Typical Budget |
|---|---|---|
| Compliance platform / SAQ tools | Most merchants | Modest annual subscription |
| Quarterly ASV scanning | Only if you have in-scope external systems | Per-quarter or annual fee |
| QSA assessment | Level 1 or complex environments only | Significant — usually not small merchants |
| Non-compliance fees | If you skip the SAQ | Recurring monthly surcharge from your processor |
Most small merchants never need a QSA — that’s reserved for Level 1 entities or those undergoing a full ROC (Report on Compliance). Self-assessment via the SAQ is your route.
Now weigh that against the cost of non-compliance: ongoing processor surcharges, and — if a breach ever occurs while you’re non-compliant — forensic investigation, card-brand fines, and potential liability. Honestly assessed, annual compliance for a small merchant costs a fraction of a single breach event. PCI compliance reduces risk; it doesn’t eliminate it, but staying current is dramatically cheaper than the alternative.
Staying Compliant Year-Round
Here’s the thing most first-timers don’t realize: PCI compliance isn’t a one-and-done task. Your SAQ is valid for a point in time, and you’ll need to revalidate at least annually — plus run your ASV scans quarterly if they apply to you.
A few practical habits keep you on track:
- Set a recurring annual reminder to renew your SAQ before your acquirer asks again.
- Schedule your quarterly scans so they never lapse (a lapsed scan can break your compliance status).
- Re-assess when things change. Switching payment processors, adding a new sales channel (phone orders, a live-event terminal), or changing how checkout works can all change your SAQ type and your obligations.
This year-round tracking is exactly what trips up busy community owners — which is why our compliance dashboard keeps your SAQ status, scan schedule, and renewal dates in one place, with reminders so nothing slips.
FAQ
I just sell community memberships on Circle.so. Do I really have to do this?
Yes — accepting any card payment, including recurring memberships, makes you a merchant subject to PCI DSS. The good news is that Circle.so’s hosted payment flow usually puts you in SAQ A, the simplest and least burdensome questionnaire.
Does Circle.so being PCI compliant mean I’m automatically compliant?
No. Your payment provider being compliant covers their systems, but you still have your own responsibilities — confirming you don’t store card data, protecting account access, and completing your own SAQ. Their compliance makes your job much smaller, but it doesn’t replace it.
What SAQ do I need for Circle.so?
For most creators using Circle’s integrated hosted checkout, the answer is SAQ A. If you take payments through other channels too, you may need an additional SAQ for those — our free SAQ Wizard confirms your exact path in minutes.
Do I need a quarterly ASV scan?
Often, no — SAQ A merchants frequently have no in-scope external systems to scan. But if you run your own website or server connected to your payment flow, a scan may apply. Confirm with your acquirer or QSA, and we can run the scan if needed.
What happens if I just ignore the questionnaire?
Your processor can apply non-compliance fees, usually a recurring monthly charge, and you’ll carry far greater liability if a breach ever occurs. Completing the SAQ is faster and cheaper than living with those consequences.
Can I store a member’s card number to rebill them later?
No — you should never store raw card numbers. Circle’s processor handles recurring billing securely through tokenization, so the card is rebilled without you ever holding the actual number. Storing card data pushes you into SAQ D, the most demanding questionnaire.
How long is my compliance good for?
Your SAQ and AOC are valid for a point in time and must be renewed at least annually, with quarterly scans where required. Significant changes to how you take payments can require reassessment sooner.
Do I need to hire a QSA?
Almost certainly not. QSAs and ROCs are for Level 1 merchants and complex environments — most small Circle.so businesses self-assess with an SAQ and never need one.
