Coupon Management

Overview

Coupon systems let merchants create promotional codes with configurable rules: percentage or fixed-amount discounts, minimum order requirements, usage limits per coupon or per customer, and expiration dates. Every major e-commerce platform includes a built-in coupon system — you almost never need to build one from scratch. This skill walks you through setting up coupon management on each platform and explains when to reach for an app or plugin for advanced requirements like bulk unique codes or campaign tracking.

When to Use This Skill

• When adding promotional codes to a checkout flow for the first time
• When migrating from a simple discount field to a rule-based coupon engine
• When running marketing campaigns that require unique, single-use codes for each recipient
• When building an admin interface to create and monitor coupon performance
• When enforcing complex coupon rules such as product/category exclusions or customer segment restrictions
