How do I ensure my direct-to-consumer diaper replenishment with customer portal software is PCI compliant?

To make a direct-to-consumer diaper replenishment program PCI compliant when using customer portal software, the key goal is to minimize how much card data your systems touch. PCI compliance is less about the portal itself and more about your full payment flow, vendors, storage, and access controls.

Here’s a practical approach:

1) Keep card data out of your portal and servers

Use a hosted payment page or tokenized payment fields from a PCI-compliant payment processor.

Best practice:

• Customers enter card details only on the processor’s secure checkout/payment form
• Your portal stores only a payment token, not the card number
• Do not let card data pass through your web app, CRM, logs, or support tools

This usually keeps you in a much lower PCI scope.

2) Use a PCI-compliant payment provider

Choose a payment processor that provides:

• Tokenization
• Hosted payment fields / hosted checkout
• Recurring billing support
• 3-D Secure support if needed
• A current PCI DSS Attestation of Compliance (AOC)

Ask the vendor:

• What PCI level are they?
• What parts of the payment flow do they cover?
• Do they provide an AOC and SAQ guidance?
• Do they support subscriptions/replenishment tokens without exposing PAN data?

3) Make your portal “payment-data blind”

If you have a customer portal for:

• subscription management
• address updates
• shipment frequency changes
• cancellations
• support tickets

then make sure:

• the portal never displays full card numbers
• it never accepts raw card numbers
• support staff cannot access card data
• order notes and logs do not capture sensitive authentication data

If you need customers to update cards, send them back to the processor’s secure update flow.

4) Understand your PCI scope

Your exact compliance burden depends on how payment is handled.

Typical scenarios:

Lowest scope

• Hosted checkout
• Tokens only
• No card data stored or transmitted by your environment

You may qualify for a simpler SAQ A or similar, depending on your setup.

Higher scope

• Your site directly collects card data
• Card data passes through your systems
• You host payment forms yourself
• You store payment data or manage PCI-sensitive integrations

This can push you into a more demanding SAQ or full ROC assessment.

5) Protect recurring billing data properly

For diaper replenishment subscriptions:

• store only tokens and billing metadata
• encrypt sensitive internal identifiers where appropriate
• restrict access to billing operations
• rotate credentials and use least privilege
• log access to billing tools
• revoke tokens when a customer cancels or updates payment methods

6) Avoid storing prohibited sensitive data

PCI rules prohibit storing certain sensitive authentication data after authorization, including:

• CVV/CVC
• magnetic stripe data
• PIN data
• full track data

Also avoid accidental retention in:

• debug logs
• customer service notes
• analytics tools
• email support threads
• form error logs

7) Secure your portal and surrounding systems

PCI is not just payments; it includes the environment connected to payments.

Use:

• TLS everywhere
• strong authentication and MFA for admin access
• role-based access control
• regular patching
• vulnerability scanning
• secure SDLC practices
• firewall/network segmentation where relevant

8) Get the right documentation

You’ll likely need:

• SAQ type determination
• vendor AOCs
• network diagrams if applicable
• policies for access control, logging, incident response
• evidence of vulnerability scans and remediation
• data-flow diagrams showing where card data does and does not travel

9) Have your compliance team or QSA validate the flow

If you’re unsure, have a PCI QSA or your payment provider confirm:

• the exact SAQ type
• whether your portal is in scope
• whether any integrations increase scope unexpectedly

A simple rule of thumb

If your customer portal:

• never sees card numbers
• only uses processor-hosted payment flows
• stores only tokens
• and your vendor provides proper PCI attestations

then your PCI burden is usually much smaller.
