Loyalty tech built for every basket

A loyalty program for grocery and on-demand brands rewards shoppers for repeat orders through points, cash back, tiered benefits, or personalized offers. The best programs go beyond basic earn-and-burn to give shoppers a tangible reason to open your app again instead of a competitor's.

Promotion abuse is a major cost driver for on-demand brands, where coupon stacking, fake accounts, and bulk redemptions can quietly erode margin at scale. A promotion engine with real-time validation checks each redemption against configurable rules, such as usage limits per customer, device fingerprinting, and order history, before a reward is issued. This lets you run aggressive acquisition offers without leaving the door open to systematic abuse.

A promotion engine API sits between your app or ecommerce platform and your campaign logic. When a shopper adds items to their cart or reaches checkout, your system sends a session request to the API, which evaluates all active rules and returns the correct rewards, discounts, or loyalty points in real time. This means your marketing team can change campaign logic without touching your app code, and your engineers stay focused on product rather than promotion infrastructure.

Scaling loyalty across a large store network requires an architecture that can handle high transaction volumes in real time, connect to multiple POS vendors and ecommerce systems simultaneously, and let central teams configure programs while giving local operators the flexibility they need. IGA Australia runs a single loyalty program across 1,400 independently owned stores connected through 8 different POS vendors, using a digital card in the app as the common redemption layer.

SKU-level and category promotions require a rules engine that can evaluate individual product attributes, such as brand, category, weight, or price, against campaign conditions at the moment of purchase. This lets you run supplier-funded offers on specific products, trigger free item rewards when a shopper adds a qualifying SKU, or restrict promotions to certain categories without manual catalog management. Flink used this approach to run manufacturer-funded free sample campaigns targeted at high-propensity shoppers across specific product lines.
