price-rules-engine

Stackable discounts with priority ordering are implemented by configuring a price rules engine that evaluates multiple concurrent promotions sequentially, ensuring deterministic discount application based on assigned rule priorities.

Targeting pricing rules to specific customer segments on Shopify, WooCommerce, and BigCommerce is supported by defining customer group conditions within the rule evaluation logic, allowing promotions for groups like VIPs or new customers.

Excluding specific products or categories from a promotional discount is handled by adding product exclusion constraints to the price rule, preventing the discount engine from applying the price reduction to restricted items like Nike products.

Building a custom price rules engine for a headless e-commerce platform is facilitated by using the provided TypeScript example for rule evaluation logic, which demonstrates how to implement stackable discounts, exclusions, and priority ordering deterministically.

Deterministic discount application during overlapping promotions works by enforcing strict priority ordering across stackable discounts, ensuring the rule engine evaluates and applies each pricing rule in a predictable, controlled sequence.
