What Is E-Commerce?
E-Commerce is the technology infrastructure that enables businesses to sell products and services online. An e-commerce platform provides the complete stack for running an online store: product catalog management, shopping cart and checkout, payment integration, order management, shipping and fulfillment, and customer account management.
Modern e-commerce platforms support multiple sales models and channels from a single platform:
- Product catalog – organize products with variants (size, color, SKU), categories, attributes, pricing tiers, digital assets, and rich descriptions; manage inventory quantities per SKU; support virtual and downloadable products alongside physical goods
- Shopping cart and checkout – session-managed cart with persistent cart recovery (abandoned cart emails), guest and registered checkout flows, address validation, coupon and discount codes, gift card redemption, and upsell/cross-sell recommendations at checkout
- Payment integration – connect to payment gateways (Stripe, PayPal, Adyen, Square) for card processing; support digital wallets (Apple Pay, Google Pay); buy-now-pay-later (Klarna, Afterpay); alternative payment methods (iDEAL, Bancontact); PCI DSS compliance through hosted payment pages and tokenization
- Order management – full order lifecycle from placement through fulfillment, shipment, and return; order editing, partial fulfillment, split shipments, backorders, and cancellations; customer order history and self-service return initiation
- Shipping and fulfillment – carrier integration (UPS, FedEx, USPS, DHL, Royal Mail) for real-time shipping rates, label generation, and tracking; fulfillment rules for warehouse routing; dropship support; integration with 3PL (third-party logistics) providers
- Digital products and subscriptions – deliver software licenses, downloadable files, and media; manage subscription plans with recurring billing, free trials, metered usage, and dunning for failed payments; enforce access control for digital entitlements
- Multi-channel selling – synchronize product listings and inventory across channels: online storefront, Amazon Marketplace, eBay, Google Shopping, Facebook and Instagram Shops, TikTok Shop, and physical POS; unified order and inventory management across all channels
- Headless commerce – decouple the storefront presentation layer from the commerce backend; expose products, cart, and checkout via REST or GraphQL APIs; power custom frontend experiences built with Next.js, Nuxt, or React Native while the platform manages commerce logic and data
- Multi-store and multi-region – operate multiple storefronts from a single platform for different brands, markets, or locales; per-store product catalogs, pricing, currencies, tax rules, and shipping zones; localized storefronts with translated content and regional payment methods
- Tax calculation – automatic sales tax for US states, VAT for EU/UK, GST for Australia and Canada; product tax class assignment; nexus management; integration with dedicated tax engines (Avalara, TaxJar) for complex compliance scenarios
- SEO and marketing – canonical URLs, structured data (JSON-LD), sitemap generation, customizable meta tags, open graph tags for social sharing; built-in blog or CMS for content marketing; integration with Google Analytics, Meta Pixel, Google Tag Manager, and email marketing platforms
