Checkout logic gets scattered across discounts, apps, and Shopify settings. Cart Marshal puts it in one control center. Scan for discounts, apps, and Shopify Functions affecting checkout, and flag when a published rule is changed or deleted in Shopify. Build discount, payment, delivery, and restriction rules with targeting and recurring schedules. See active, upcoming, and expired rules on one timeline, read a plain-language summary before publishing, and keep a full audit trail with CSV export.

• Scan for unknown discounts, apps & Shopify Functions affecting checkout.
