MerchantKit: Store Tools

MerchantKit brings checkout rules and store-health workflows into one embedded Shopify app. Hide, rename, or move payment methods using AND / OR conditions based on cart, customer, delivery, B2B, and product context. Create targeted product and cart warnings, require acknowledgments, enforce checkout validation, review consent evidence, and monitor metafield sync health. Shopify Plus stores can also use payment terms, B2B order review, and placement-specific checkout controls.
