Why TikTok Shop vs Shopify checkout matters for Shopify brands
Shopify sellers already have products, inventory and customers. Brands pick one checkout by habit and never measure the trade-offs.
The goal is not just more TikTok Shop GMV — it is more total contribution margin across Shopify and TikTok Shop.
