Advanced WooCommerce discount rules engine. Build conditional pricing strategies without touching code — percentage, fixed, tiered/bulk, role-based, and BOGO rules with date and cart conditions.

Features

  • Percentage & Fixed Discounts — apply to individual products, categories, or entire catalog
  • Tiered/Bulk Pricing — quantity breaks with configurable discount tiers
  • Role-Based Pricing — different prices per customer role (wholesale, VIP, etc.)
  • BOGO Rules — Buy X Get Y free or discounted
  • Condition Chaining — date range, minimum cart total, and role conditions
  • HPOS Compatible — fully supports WooCommerce High-Performance Order Storage
  • Cache-Aware — rules cached in the WP object cache, auto-invalidated on save
  • PHPUnit Tested — unit test coverage for the discount engine

Installation

composer install

Then activate in WordPress admin > Plugins.

Architecture Decisions

Decision Rationale
Custom Post Type for rules Leverages WP revision history, REST API, and role capabilities without a custom table
Object cache for rules Prevents repeated DB queries on every product price calculation
match expression for discount types Exhaustive, readable, and throws UnhandledMatchError on unknown types — fast-fail over silent bugs
HPOS declaration Required for WooCommerce 8.x compatibility; future-proofs the plugin
