BigCommerce's Script Manager exists specifically so merchants can add third-party scripts without editing raw theme templates — set the placement to head and all pages, and Orbit covers the whole storefront.
Not necessarily — depending on your checkout type (standard vs. optimized/custom checkout), checkout can run on a separate flow, so confirm coverage there separately if checkout-page tracking matters to you.
Yes — Script Manager is a standard part of the BigCommerce control panel across plans, not a paid add-on.
No — Script Manager only injects into BigCommerce's own Stencil-themed storefront. On a headless setup (e.g. a custom frontend), add the script directly to that frontend's head template instead.
No — Script Manager is designed to run multiple independent third-party scripts side by side without conflict.
