The Business Challenge

Legacy Monolith & Checkout Bottlenecks

A regional industrial hardware distributor had outgrown their 12-year-old monolithic e-commerce software. Page loading times averaged 6.8 seconds per catalog page, while wholesale buyers trying to order hundreds of line items experienced browser freezes and timeouts.

Customer-specific contractual pricing tiers required overnight database batch updates, leading to frequent pricing discrepancies, manual credit memos, and dissatisfied commercial accounts.

Project Objectives

Target Performance Milestones

  • 1. Sub-1-Second Catalog Browsing & Search Deliver instant faceted search across 40,000+ SKUs with real-time stock levels per regional warehouse.
  • 2. Tiered Customer Pricing Engine Dynamically calculate volume-based tier pricing, negotiated customer rates, and credit limits on the fly.
  • 3. Bulk Order CSV & Quick-Entry Matrix Enable procurement officers to upload multi-hundred SKU spreadsheets and process PO orders in under 30 seconds.
Technical Solution

Decoupled Engineering & Bi-Directional ERP Sync

Decodrz designed a modern headless architecture. The frontend uses a lightweight, semantic HTML5/Bootstrap interface optimized for speed and keyboard accessibility, served globally via CloudFront CDN.

The backend utilizes Node.js microservices coupled with an Elasticsearch cluster for instant multi-attribute search. A dedicated bi-directional connector synchronizes inventory, invoice status, and credit limits with the client's SAP ERP system via secure REST/Webhooks.
