Voucherify
While generating simple coupon codes is trivial, Voucherify provides a high-throughput, ACID-compliant rule engine for stackable discounts, gift card double-entry ledgers, and dynamic customer segmenting. Rebuilding this leads to severe concurrency issues during high-volume sales drops when thousands of checkouts target the same discount code simultaneously.

- Basic static coupon code generation and verification
- Fixed percentage or fixed amount cart-level discounts
- Basic SKU or collection applicability checks
- Simple minimum order value validation rules
- Triggering email webhooks when a discount code is issued
what you lose
- Visual drag-and-drop rule builder for non-technical marketers
- Atomic concurrency controls preventing double-redemption race conditions during flash sales
- Double-entry ledger accounting and audit trails for gift card balances
- Real-time point expiration, reward redemption, and tier calculation engine
- Built-in referral fraud detection heuristics and IP rate-limiting
