The most expensive mistake an e-commerce business in Cape Town can make is commissioning a website from an agency that treats checkout as an afterthought. Conversion rates for online stores in South Africa average 1.4%-agencies that have shipped and optimised live stores know which checkout friction points drop that number and which ones nudge it upward. This list covers Cape Town web developers with verifiable e-commerce delivery records, not agencies that added a Shopify logo to their portfolio page.

Buyer's Checklist
These are the questions and checks that separate e-commerce specialists from general web agencies who will list your sector on their homepage after you sign.
Published live stores with page speed scores above 80 on GTmetrix-ask for the report before signing
Checkout A/B testing experience: agencies that have run live split tests understand what moves conversion rates beyond gut instinct
Local payment method integrations: Stripe, PayPal, and any market-specific gateways active in Cape Town
SEO-ready product architecture: canonical URLs, structured data for products (Schema.org/Product), faceted navigation without crawl debt
Post-launch support with defined SLA-e-commerce sites fail during peak traffic, usually when you least want to be calling a developer
Platforms & Tech Stack
Shopify / Shopify Plus
Best for speed to market. Custom theme development on Shopify 2.0 gives full design control without leaving the hosted platform. Shopify Plus is the correct choice above £500,000 annual GMV.
WooCommerce
Best when the client already runs WordPress or needs customisation beyond Shopify's API surface: subscription logic, complex tax rules, multi-currency with local rounding.
Headless (Next.js + Shopify Storefront API)
Recommended for stores exceeding 10,000 monthly transactions or brands that require sub-1-second product pages. Higher build cost; dramatically better Core Web Vitals scores.
Magento 2 / Adobe Commerce
Enterprise choice for multi-store, multi-language, multi-currency setups. Requires a dedicated Magento-certified developer-not all Cape Town agencies have this.

Questions & Answers
Pre-brief questions that e-commerce businesses in Cape Town ask before commissioning a web project.
Shopify is the default recommendation for most Cape Town businesses launching a new store-faster to build, easier to operate, and lower ongoing maintenance. WooCommerce is the right choice when the client already runs WordPress or needs more complex customisation. Headless commerce (Next.js + Shopify API) suits stores exceeding £1M GMV where load speed and UX directly impact revenue.
A Shopify store with brand-customised theme costs £1,500–£5,000 in Cape Town. A custom WooCommerce build with product filtering and payment gateway integration runs £5,000–£18,000. Enterprise headless commerce starts at £25,000. Ongoing costs include hosting (£20–£200/month), platform fees (Shopify £29–£299/month), and maintenance retainers.
A Shopify store with a customised premium theme takes 1–3 weeks. A custom WooCommerce build is 4–8 weeks from brief to launch. A headless commerce platform with custom checkout flows and ERP integrations is 12–24 weeks. Timelines extend when product data, photography, or payment gateway approvals are delayed.
E-commerce development requires specific expertise that general web developers often lack: checkout conversion optimisation, inventory management integration, tax and shipping logic, and PageSpeed compliance affecting Google Shopping rankings. Ask any candidate agency to show you 3 live stores and their current Core Web Vitals scores in Google Search Console.
