Custom Promotion App for a Retail eCommerce Client on Shopify

Services Offered: Shopify Integration and Migration

Industry: E-commerce/Retail

Overview

A leading retail eCommerce brand with a strong promotional strategy migrated to Shopify to modernize their online shopping experience. However, their advanced and frequent promotional needs could not be met using Shopify’s native capabilities or even with multiple third-party discount apps.

The Challenge

Upon migration, the client faced significant limitations with Shopify’s out-of-the-box discount engine. While Shopify supports basic promotion types, the client required far more nuanced capabilities, including:
Stacked promotions across SKUs and order levels

To make things work temporarily, the client had to install and juggle 4–5 different third-party apps. Even then, gaps persisted in setup flexibility, performance, and the ability to reflect accurate promotion messaging across the shopping funnel.
