What Is E-Commerce, Really?
E-commerce simply means buying and selling products or services over the internet. It covers everything from a one-product Shopify shop to a multi-warehouse Amazon seller — and it's how 36% of all UK retail now happens.
The 4 Main Types of E-Commerce
B2C (selling to consumers — e.g. ASOS), B2B (selling to other businesses — e.g. RS Components), C2C (consumer-to-consumer — e.g. eBay, Vinted), and D2C (direct-to-consumer brands cutting out retailers — e.g. Gymshark).
Platforms: Shopify vs WooCommerce vs Custom
Shopify is the fastest way to launch (£25–£300/month, hosted, supports Klarna/Apple Pay out of the box). WooCommerce is free but requires WordPress hosting and more technical work. Custom builds suit complex catalogues but cost £10k+.
Payments: What UK Customers Expect
In 2026, UK shoppers expect Apple Pay, Google Pay, PayPal, and Klarna (buy-now-pay-later) at minimum. Stripe and GoCardless are the dominant payment processors. Card-only checkouts now lose ~30% of mobile customers.
VAT, Tax & HMRC Compliance
Once you turn over £90,000/year you must register for VAT (20% standard rate). E-commerce platforms like Shopify auto-calculate VAT. For EU sales, you may need IOSS registration. Always issue VAT invoices for B2B orders.
Shipping, Returns & Consumer Rights
UK Consumer Contracts Regulations give buyers a 14-day return right on most goods. Royal Mail, DPD, Evri, and Amazon Logistics dominate fulfilment. Free delivery over a threshold (£40–£60) is now expected by 70% of shoppers.
GDPR, Cookies & ICO Rules
You must publish a privacy policy, get explicit cookie consent (PECR rules), and register with the ICO (£40–£60/year). Storing customer data in the EU/UK is preferred — avoid US-only services without a Data Processing Agreement.
Marketing: How People Actually Find Your Shop
Top UK traffic sources for e-commerce: Google organic search (SEO), Google Shopping ads, Meta (Instagram + Facebook) ads, TikTok Shop, email marketing (Klaviyo), and influencer partnerships. SEO is slowest but cheapest long-term.
