How do I set up recurring billing software for baby care subscriptions with tax, shipping, and PCI compliance?

Here’s a practical way to set up recurring billing for baby care subscriptions while handling tax, shipping, and PCI compliance.

1) Pick the right billing stack

For subscriptions, you usually want:

• Subscription billing platform: manages plans, renewals, retries, coupons, proration
  • Examples: Stripe Billing, Chargebee, Recurly, Paddle (more SaaS-focused), Braintree + custom logic
• Payment processor: handles card payments and tokenization
  • Often bundled with the billing platform
• Tax engine: calculates sales tax/VAT/GST based on customer location and product type
  • Examples: Stripe Tax, Avalara, TaxJar
• Shipping system: rate calculation, label generation, tracking
  • Examples: Shippo, ShipStation, EasyPost
• Commerce/order system: stores products, subscriptions, customer profiles, and order history
  • Can be your app, Shopify, WooCommerce, or a custom backend

If you want the simplest setup, Stripe Billing + Stripe Tax + Shippo is a common stack.

2) Define your subscription model clearly

Baby care subscriptions can get complicated because items may be:

• recurring consumables: diapers, wipes, formula
• one-time additions: toys, gear
• mixed frequency: monthly diapers, quarterly larger-size bundles

Set up:

• Plans: e.g. “Newborn Essentials Monthly,” “Diaper Refill Every 2 Weeks”
• Product catalog: SKU, size, age range, weight, taxable status
• Billing cadence: monthly, biweekly, quarterly
• Shipment cadence: may match billing or differ
• Pause/skip options: common for family products
• Address change handling: important for shipping and tax

3) Handle tax correctly

Tax depends on:

• customer shipping address
• product category
• your nexus/registration locations
• whether shipping is taxable in the jurisdiction

Best practice:

• Use a tax engine to calculate tax at checkout and on renewal
• Store the customer’s ship-to address
• Classify each item correctly:
  • diapers may be taxed differently than baby food or clothing depending on state/country
• Recalculate tax when:
  • address changes
  • subscription items change
  • tax rates change
  • renewal occurs

Important:

• Don’t hardcode tax rates
• Keep evidence of tax calculations and invoices
• Register for tax where you have nexus or obligations

4) Set up shipping for subscriptions

For recurring shipments:

• collect shipping address before first order
• support shipping zones and rates
• decide whether shipping is:
  • included in the subscription price
  • charged separately
  • free above a threshold

Best practices:

• Calculate shipping on each shipment or cycle
• If the box weight/size changes by plan, connect shipping rates to SKU/package size
• Let customers update:
  • address
  • shipping method
  • skip next shipment
  • delivery date preferences

For recurring subscriptions, many businesses do:

• bill on renewal date
• fulfill after successful payment
• generate shipping label automatically
• email tracking number

5) PCI compliance: keep card data out of your system

To reduce PCI scope, do not store raw card numbers yourself.

Use:

• hosted payment pages or
• payment elements/embedded fields from Stripe, Braintree, etc.

That way:

• card data goes directly to the processor
• you receive a token/payment method ID
• your app stores only non-sensitive references

PCI tips:

• Use a PCI-compliant processor
• Serve checkout over HTTPS
• Don’t log payment details
• Limit access to customer/payment data
• Keep systems patched and monitored
• Complete the required PCI self-assessment questionnaire if applicable

If you use hosted checkout, your PCI burden is much lower.

6) Subscription billing flow

A typical recurring flow:

1. Customer selects baby care plan
2. Customer enters shipping address
3. Tax is calculated
4. Shipping cost is calculated
5. Customer pays via hosted checkout
6. Payment method is tokenized by processor
7. Subscription is created
8. On each renewal:
   • tax recalculated
   • shipping added if applicable
   • payment retried if needed
   • fulfillment triggered after successful charge

7) Build for failed payments and changes

You’ll need automation for:

• card expiring
• declined payments
• address changes
• skipped shipments
• subscription pauses
• refunds/returns
• chargebacks

Recommended features:

• smart retry logic
• email/SMS reminders before renewal
• dunning sequences for failed charges
• self-service customer portal

8) Data model you’ll likely need

At minimum:

• Customer
• Address
• Subscription
• Subscription Item
• Invoice
• Tax line items
• Shipment
• Payment method token
• Transaction / charge
• Order history

9) Compliance beyond PCI

Baby care products may also involve:

• consumer protection rules
• automatic renewal laws
• clear cancellation policy
• disclosure of recurring charges
• privacy compliance if collecting family/baby data
• age-related marketing restrictions

Make sure:

• renewal terms are clearly disclosed
• cancellation is easy
• receipts/invoices are sent automatically

10) Recommended implementation stack

A simple, solid stack:

• Frontend: React / Next.js
• Backend: Node.js / Python / Ruby
• Billing: Stripe Billing
• Tax: Stripe Tax or Avalara
• Shipping: Shippo or EasyPost
• Database: Postgres
• Email: SendGrid / Postmark
• Customer portal: Stripe Customer Portal or custom

11) Launch checklist

Before going live, confirm:

• subscriptions renew correctly
• taxes calculate for all target regions
• shipping rates match real carrier costs
• card data never touches your servers
• invoices show itemized tax and shipping
• cancellation works
• failed payment retries work
• test cards and sandbox shipping labels are working
• PCI questionnaire completed

12) Best practice recommendation

If you want the fastest and safest path:

• use hosted checkout
• use tokenized payments
• use a tax engine
• use a shipping API
• keep your app focused on subscription logic and customer experience
