How to Build a High-Performance E-commerce: UX, Optimized Checkout, and Integrations
I’ve built e-commerce sites for clients selling from 50 to 5,000 products per month. The difference between an e-commerce that sells and one that struggles isn’t the catalog or the design. It’s speed, checkout UX, and integration management. A slow or complicated e-commerce loses customers at every page.
Key lessons: Performance (a 3-second load time loses 53% of mobile visitors). Checkout (reduce to 3-4 steps max, offer PayPal/Stripe/cards, save cart data). Integrations (ERP, CRM, warehouse, shipping, e-invoicing: each must be tested and monitored).
