Riptide is a loyalty system that helps Shopify merchants reward repeat customers and earn referrals. Customers earn points on purchases and redeem them at checkout for fixed-dollar discounts, percentage-off discounts, or shipping rewards. Merchants can run time-limited specials with point multipliers, set up VIP tiers with their own perks, and run two-sided referral rewards. Built natively for Shopify with theme extensions, customer accounts, checkout, and Shopify Flow.
