Full Answer
What looks free is rarely free. Free WooCommerce tracking plugins (the GA4 plugin, basic pixel plugins, GTM4WP) handle browser-side events but cannot do server-side delivery on their own — they need a Google Tag Manager server container, a Google Cloud project, a managed host like Stape, and 50-120 hours of developer time at $100-150/hour. Seresa's 5-year cost analysis puts the all-in TCO at $70K-$145K. Paid plugins that include native server-side delivery ship with the infrastructure built in: configuration is admin-screen settings, and developer involvement drops to occasional. The honest comparison is subscription vs subscription plus a developer.
