Modern WooCommerce Architecture Example

<?php
// Custom WooCommerce configuration
add_action('woocommerce_before_calculate_totals', 'custom_price_logic');

function custom_price_logic($cart) {
    if (is_admin() && !defined('DOING_AJAX')) return;
    
    foreach ($cart->get_cart() as $cart_item) {
        $product = $cart_item['data'];
        $quantity = $cart_item['quantity'];
        
        // Volume-based dynamic pricing
        if ($quantity >= 10) {
            $discount = 0.15; // 15% discount
            $new_price = $product->get_regular_price() * (1 - $discount);
            $product->set_price($new_price);
        }
    }
}

// Custom REST API for headless commerce
add_action('rest_api_init', function() {
    register_rest_route('custom/v1', '/products/featured', [
        'methods' => 'GET',
        'callback' => function() {
            $args = [
                'status' => 'publish',
                'featured' => true,
                'limit' => 12
            ];
            $products = wc_get_products($args);
            
            return array_map(function($product) {
                return [
                    'id' => $product->get_id(),
                    'name' => $product->get_name(),
                    'price' => $product->get_price(),
                    'image' => wp_get_attachment_url($product->get_image_id())
                ];
            }, $products);
        },
        'permission_callback' => '__return_true'
    ]);
});

Implementing a WooCommerce Store

1. Install WordPress on performant hosting with SSL, then add WooCommerce plugin from official directory
2. Configure fundamental settings: currency, country, tax zones, shipping methods, and payment gateways (Stripe, PayPal)
3. Import or create product catalog with attributes, variations, optimized images, and SEO-friendly descriptions
4. Choose and customize a WooCommerce-compatible theme or use a builder like Elementor for design
5. Install essential extensions based on needs: inventory management, invoicing, marketing automation, multilingual support
6. Optimize performance with caching (WP Rocket, Redis), CDN, and image compression for fast loading times
7. Configure transactional emails, legal pages (terms, privacy policy), and secure payment methods
8. Set up analytics (Google Analytics 4, Facebook Pixel) and conversion tools to measure performance
