Ecommerce (electronic commerce) is the buying and selling of goods and services over the internet, including the transfer of money and data to execute these transactions. Global ecommerce sales exceeded $6 trillion in 2024 and continue to grow as buyer behavior shifts online across virtually every product category.
Whether you sell physical products, digital downloads, subscriptions, or professional services, ecommerce infrastructure is the engine behind online revenue.
Types of Ecommerce
B2C (Business to Consumer)
The most familiar model: a business sells directly to individual consumers. Think retail stores online — apparel, electronics, health products, food. B2C is characterized by high transaction volume, lower average order values, and a focus on customer acquisition and conversion rate.
B2B (Business to Business)
B2B ecommerce handles transactions between businesses. Features often required include:
- Account-based pricing (different rates per customer)
- Bulk ordering and minimum quantities
- Purchase order (PO) support
- Net payment terms (Net 30, Net 60)
- Multi-user accounts with approval workflows
- Custom product catalogs per customer
B2B ecommerce has higher average order values and longer sales cycles than B2C.
C2C (Consumer to Consumer)
Platforms where consumers sell to other consumers. eBay and Facebook Marketplace are examples. This model typically requires marketplace infrastructure.
Multi-Vendor Marketplace
A multi-vendor marketplace aggregates multiple sellers on one platform. The platform operator manages infrastructure, payments, and trust while sellers list their own products. Commissions or subscription fees generate revenue.
Core Ecommerce Infrastructure
Product Catalog and Inventory
A reliable inventory management system tracks stock levels, SKUs, variants (size, color), and availability across channels. Poor inventory management leads to overselling, stockouts, and customer service issues.
Payment Gateways
A payment gateway processes transactions securely. Key considerations:
| Gateway | Best For |
|---|---|
| Stripe | Developer-friendly, subscription support |
| PayPal | Consumer trust, international payments |
| Square | In-person + online unified commerce |
| Authorize.net | Enterprise B2B and legacy integrations |
Checkout UX
Checkout is where most ecommerce revenue is won or lost. Best practices:
- Guest checkout option (no forced account creation)
- Minimal form fields
- Multiple payment methods (cards, PayPal, Apple Pay, Buy Now Pay Later)
- Clear shipping cost and delivery date estimates
- Trust signals near the buy button
Order Management
After payment, orders must be fulfilled, tracked, and managed. Order management systems (OMS) handle fulfillment routing, shipping label generation, return processing, and customer notifications.
Platform Options
| Platform | Best For |
|---|---|
| Shopify | SMB retail, fast launch, app ecosystem |
| WooCommerce | WordPress-based stores, existing WP sites |
| Magento / Adobe Commerce | Large catalog enterprise retail |
| BigCommerce | Growing brands, B2B support |
| Custom build | Unique models, marketplaces, complex B2B |
Platform selection should be driven by your transaction volume, customization requirements, integration needs, and long-term scalability — not by which platform is easiest to demo.
Headless Ecommerce
Headless commerce separates the frontend presentation from the ecommerce backend. A headless storefront delivers faster pages (often 2–4x better Core Web Vitals), greater design freedom, and the ability to sell across web, mobile, and other channels from a single backend.
