Tab Promo: Discounts & Tiers

Tab Promo is a rule-based promotion engine that helps you run checkout discount campaigns on Shopify. Build campaigns using conditional rules based on customer data, cart contents, products, and location, then publish them as Shopify Functions discounts or promo codes. The app reads customer, product, and variant metafields as discount conditions, letting you turn data from your loyalty programs, review apps, or CRM tools into checkout promotions. Run multiple discount campaigns simultaneously, each with custom rules and schedules. Every campaign can be tested on sample carts before going live. All published versions are tracked and reversible, so you can roll back changes in one step. You can also display campaign progress and discount eligibility on your storefront pages through the API.
