Your Best-Selling WooCommerce Product Might Be Losing You Money

GA4 and WooCommerce Analytics rank products by revenue, not profit—causing store owners to promote their highest-revenue products while ignoring products with better margins. Average ecommerce gross margin is 45%, but net margin drops to just 10% after marketing, shipping, and operations (Opensend, 2024). Without cost of goods sold (COGS) data in analytics, profitable SKUs silently subsidize loss-making SKUs (Finaloop, 2025). WooCommerce has no native COGS field, and no standard analytics dashboard calculates contribution profit per product. The solution is streaming complete order data to BigQuery where COGS can be joined with event data for true product-level profitability analysis.
