Building E-Commerce for Regulated Industries

Not every product can be sold through a standard Shopify store. Some industries have compliance requirements that generic platforms either can't handle or actively restrict. I learned this firsthand building an e-commerce platform for the research peptide space.

Why Generic Platforms Fall Short

Shopify, BigCommerce, and similar platforms have acceptable use policies that restrict certain product categories. Even when your product is legal, the platform may flag or suspend your store without warning. Beyond that, regulated industries often need custom verification steps, disclaimers, and documentation workflows that no plugin can handle properly.

The answer is building custom. It's more work upfront, but you own the entire checkout experience.

Age Verification at the Gate

For regulated products, age verification can't be an afterthought. I implemented it as middleware that intercepts every product and checkout route:

// middleware.ts - age gate before any product access
export function middleware(request: NextRequest) {
  const verified = request.cookies.get("age-verified");

  if (!verified && request.nextUrl.pathname.startsWith("/products")) {
    return NextResponse.redirect(new URL("/verify-age", request.url));
  }

  return NextResponse.next();
}

The verification page collects a date of birth, validates it server-side, and sets a signed cookie. No client-side JavaScript tricks that can be bypassed.

Compliance Disclaimers in the Checkout Flow

Regulated products often require the buyer to acknowledge specific terms before completing a purchase. I built this as a required step in the checkout flow, not a modal that users click through without reading.

// Server action - validate disclaimer acceptance before processing
async function processCheckout(formData: FormData) {
  const disclaimerAccepted = formData.get("research-disclaimer");
  const ageConfirmed = formData.get("age-confirmation");

  if (!disclaimerAccepted || !ageConfirmed) {
    return { error: "All compliance acknowledgments are required." };
  }

  // Log acceptance with timestamp for compliance records
  await db.complianceLog.create({
    data: {
      orderId,
      disclaimerAcceptedAt: new Date(),
      ipAddress: headers().get("x-forwarded-for"),
    },
  });
}

Every acknowledgment is timestamped and logged. If there's ever a compliance audit, the paper trail exists.

Stripe for Restricted Categories

Stripe supports regulated products, but you need to classify them correctly. This means setting the right product metadata and being transparent about what you're selling during onboarding.

const product = await stripe.products.create({
  name: "BPC-157 Research Compound",
  metadata: {
    category: "research-peptide",
    requires_age_verification: "true",
    compliance_class: "research-use-only",
  },
});

The key insight: Stripe won't reject you for selling regulated products if you're upfront about it. The problems start when merchants try to obscure what they're selling. Be transparent during account setup, classify your products correctly, and maintain proper documentation.

Key Takeaways

1. Build custom when the platform can't comply. Plugin-based compliance is fragile and unreliable.
2. Enforce verification server-side. Client-side age gates are theater.
3. Log everything. Compliance audits happen. Timestamped records protect you.
4. Be transparent with Stripe. Proper product classification prevents account freezes.

I built this for Anarchy Research, a research peptide supplier that needed a compliant storefront from day one. The result is a checkout flow that satisfies legal requirements without destroying the user experience.
