Setting up Google Tag Manager by hand means editing theme.liquid, writing a data layer and rebuilding it after every theme update. GTM Kit does all of it for you. Paste your GTM container ID and the app pushes view_item, add_to_cart, begin_checkout and purchase events, with product and order value, straight to your data layer. From there, fire GA4, Google Analytics, Google Ads and Facebook Pixel tags in one container. Prebuilt tags and triggers included, so tracking is live in minutes.
