Client Overview

A US-based, mid-market fashion brand with $60M in annual revenue was experiencing stagnating online sales. Their PrestaShop store was slow, averaging a 6-second load time, and lacked the customization needed to compete with larger retailers. They struggled with manual inventory updates between their store and their ERP, leading to stock discrepancies and poor customer experience.

D2C Fashion Website Performance Problem

Problem

The client's growth was being throttled by their technology. A slow, generic PrestaShop site was leading to high bounce rates, while inefficient manual processes were draining resources and causing costly errors.

Key Challenges

Zero Downtime Migration Challenge

Poor Performance

Page load times exceeded 6 seconds, causing a 50%+ bounce rate.

Fast Page Load Speed Challenge

No ERP Integration

Manual inventory updates took 20+ hours per week and led to overselling.

Unique UX Challenge

Generic User Experience

The standard theme lacked features for product personalization and upselling.

High Traffic Handling Challenge

Lack of Expertise

Their small in-house team lacked the specialized PrestaShop skills to solve these core issues.
