rata.id
Warehouse and logistics platform needed automated pricing, discount rules, and coupon management. Built backend systems to handle complex pricing logic at scale.
The Problem
Rata.id's warehouse and logistics operations required a sophisticated pricing engine to handle dynamic pricing, bulk discounts, promotional coupons, and SEO-optimized product listings. The existing manual processes couldn't scale with business growth and led to pricing inconsistencies.
Constraints
Pricing rules must support complex conditions (volume, time-based, customer segments)
Discounts and coupons must apply correctly without race conditions
SEO requirements for product listings with dynamic pricing
System must handle high-volume transactions during promotional periods
