Custom Ecommerce Platforms for Regulated Products: What to Do When Mainstream Platforms Say No

A custom ecommerce platform gives regulated retailers the control that mainstream platforms often won’t. Shopify, BigCommerce and Squarespace may restrict the products, payment methods, checkout processes or shipping options available to sellers of fireworks, supplements, CBD, alcohol and vaping products.

Unlike standard Software-as-a-Service (SaaS) platforms, which have their own policies and restrictions, a custom platform allows businesses to build an online store around their specific requirements. This can reduce their reliance on third-party providers and minimize the risk of disruptions caused by policy changes.

A custom ecommerce website lets these businesses manage catalogue rules, age verification, payment gateways, hosting, and shipping options according to their specific needs. However, a custom platform does not remove legal responsibilities. Businesses must still comply with all applicable laws and regulations.

Why Do Regulated Products Face Platform Restrictions?

Shopify, BigCommerce, or Squarespace work with global payment processors and are subject to a wide number of internal and external regulations. A custom approach lets the retailer set its own product, customer and order rules.

Regulated products often need special handling, such as age verification, shipping restrictions and different rules in each jurisdiction. In the UK, alcohol sales fall under the Licensing Act 2003, and nicotine vapes and most consumer fireworks can only be sold to adults.

Products that need special handling are often restricted or prohibited on mainstream platforms. A real-world example is Shopify’s approach to vaping products.

• Age verification
• Restrictions on where products can be shipped
• Varying legal restrictions across jurisdictions

Products that need special handling are often restricted or prohibited on mainstream platforms. A real-world example is Shopify’s approach to vaping products.

• A coalition of 25 US state attorneys general and the City of New York had urged the company to take stronger action against illegal e-cigarette sales.
• Following those calls, the California Attorney General’s Office described Shopify’s decision as a ban on all vaping products, including e-cigarettes.

Shopify’s Acceptable Use Policy sets out which products merchants can and can’t sell. Policies like this can change at any time, which is why depending on one platform is a risk for regulated retailers.

Choosing the Right Ecommerce Architecture

You need to have your own code and your own hosting environment to be able to protect your business. If a specific provider changes their policy, a custom platform will give you the ability to switch out the backend services.

• Open-Source Ecommerce Platforms

Self-hosted options such as WooCommerce (on WordPress) and Magento Open Source give you the flexibility to build what you need.

Adobe Commerce, the paid version of Magento, is widely used for high-volume catalogues, complex wholesale workflows and advanced pricing rules.

• Headless Commerce for Greater Flexibility

This divides your website into two components: front end (the part your customers see) and back end (your website logic and database). Separating these layers enables the use of specific tools without restriction to any specific ecosystem.

Many large retailers use headless commerce because it lets them redesign the storefront, add new sales channels or swap backend services without rebuilding the whole site. For regulated retailers, that same flexibility means you can replace a payment gateway or compliance tool if a provider changes its policy.

Before you build a custom ecommerce platform, consider the specific problems that you can’t solve with your current platform.

Choose Payment Providers That Support Regulated Businesses

Mainstream processors such as Stripe and PayPal restrict or prohibit many high-risk sectors.

• To ensure revenue continues to flow, you need to install special gateways.
• With a custom build, you can directly communicate with High Risk Merchant Account Providers.
• In addition, you can integrate Alternative Payment Methods (APMs) such as bank transfers (BACS or Faster Payments) or open banking payments.

Build Compliance Checks Into the Checkout

Compliance should be built into checkout from day one, not added later.

Verify Customer Age Before the Purchase

A simple “Are you over 18?” pop-up isn’t enough. Use a UK age-verification provider such as Yoti or VerifyMy to check customers at checkout, using ID documents, credit reference data or facial age estimation.

For alcohol and age-restricted deliveries, the check should happen twice: once online, and again at the door, with couriers following Challenge 25 when handing over the order.

Restrict Orders by Location

Some products can be sold in one country but not another, or need a licence to ship.

IP geolocation and postcode restrictions should be implemented on a custom platform to block sales to jurisdictions where the product is prohibited.

Enforce Product and Purchase Limits

Some regulated categories, such as over-the-counter medicines, CBD, supplements and nicotine products, come with quantity limits. These may be set by law, regulator guidance or your own compliance policy. For example, UK retailers limit how many packs of paracetamol a customer can buy in one transaction.

These limits need to be applied automatically by your backend, per order and across repeat orders, so your store stays compliant without relying on manual checks.

As a business, these restrictions need to be imposed automatically by your backend so you can be compliant. 

Choose Hosting That Supports Your Business Model 

Your hosting provider could terminate your account even on open-source software with a high-risk gateway, if they don’t accept your product category. 

• Avoid generic, low-cost shared hosting if it cannot meet your business’s security and performance requirements.
• Instead, choose high-performance, secure cloud hosting that supports your business model. 

Additionally, setting up a custom domain for an ecommerce platform helps preserve your brand identity no matter the physical location of your servers.  

For UK retailers, make sure your hosting and data handling comply with UK GDPR. 

Build SEO Into Your Ecommerce Platform From the Start 

There are several restrictions on ads for regulated products on mainstream advertising platforms such as Google Ads, Meta, and TikTok. This means you need to be creative in your customer acquisition strategy. This makes organic search a much bigger growth channel. 

1. SEO Becomes More Important When Paid Ads Are Restricted 

Because you can’t depend on paid ads, your site structure needs to be very optimised for organic search traffic. A custom build can give you the ability to build a powerful content management system that supports  

• Rich educational material
• Blogs
• High-speed product pages 

2. Use Affiliates and Influencers to Reach the Right Customers 

Your platform should feature a custom-designed tracking system to recognise niche influencers and reviewers who are able to legally promote your product on their own outlets. 

3. Monitor Which Marketing Channels Are Making Sales 

A bespoke ecommerce system could enable regulated product retailers to monitor customer signals and gauge marketing efficiency via authorised channels. Ecommerce marketing attribution determines touchpoints, which impact purchases, such as: 

• Organic search
• Email campaigns
• Affiliate referrals
• Direct visits.  

This assists retailers in knowing the channels that attract customers and drive sales. Retailers are also able to monitor 

• Creator referrals
• Organic search
• Consent based first-party data  

to gain insight into the customer journeys. 

Attribution insights can be used by retailers to: 

• Measure conversions: Identify the channels that lead to purchases.
• Budget allocation: Focus spend on outlets that can produce quantifiable outcomes.
• Understand customer journeys: Monitor how customers learn about products and go back to purchase.
• Optimize performance of the campaigns: Review performance and optimize marketing. 

Because advertising policies differ according to product and medium, retailers must confirm what types of promotional tactics are allowed at that time, and then invest in a campaign.

B2B Regulated Ecommerce Needs More Than a Standard Store 

If you have wholesale or distribution activities in your company, the process gets even more complicated.  

• For businesses that operate with account hierarchies, dynamic price lists, and bulk ordering, having a custom B2B ecommerce platform is essential.
• For example, a building-materials supplier needs to reflect specific measurements, grades, volumes, distribution zones, and customer pricing.  

The best custom B2B ecommerce platform connects to your existing ERP through API system integrations. When choosing a development partner, prioritise one that understands B2B workflows. 

Is a Custom Ecommerce Platform Right for Your Business? 

In a Shopify vs custom ecommerce platform comparison, Shopify is quicker to launch but gives you less control. A custom platform involves trade-offs you should plan for:

• Higher upfront investment: development costs more than a SaaS subscription at the start.
• Ongoing security patching and PCI responsibility: you own server updates, security monitoring and payment compliance.
• Support and maintenance: you need a development partner or an in-house team to keep the platform up to date.

With the right development partner, each of these is manageable, and for regulated retailers the control you gain usually outweighs the extra effort.

• Retailers can also use marketing data to determine whether their ecommerce platform is generating business growth.
• Linking website analytics, sales reports and authorized advertising data will allow businesses to compare channel performance and detect any gaps in customer tracking.  

For companies that are considering going down this path, Ecommerce Excellence can help them make the decision based on platform flexibility and compliance with workflow/operation requirements.
