Purchase tracking is the most critical element of ecommerce analytics — yet it's also the most commonly broken. Duplicate transactions, missing revenue, incorrect product data, and post-purchase-page tracking all corrupt your data and inflate or deflate your reported ROI. Our purchase tracking service implements the GA4 purchase event correctly, with deduplication logic, accurate transaction IDs, complete product item arrays, and thorough validation against your actual order data.
