Dekoracja Domu — PrestaShop Store with Multi-Retailer Marketplace Integrations

Situation, goals and challenges

Dekoracja Domu is an online retailer specializing in home décor and interior accessories. At the start of the project, the store was running on outdated infrastructure while already supplying both direct retail customers and major marketplace partners — including Carrefour, Tesco, and Empik — which meant it needed dependable integrations and automated data flows.

Project goals: - launch a new store on PrestaShop 1.6 capable of handling a large product catalog - design a clean, easy-to-navigate interface - automate product feed exports to marketplace partners - support two warehouses with different stock levels and delivery times - introduce a "deal of the day" feature on the homepage - strengthen SEO and content structure

Key challenges: - integrating with external retail partners (Carrefour, Tesco, Empik), each requiring a different feed format - handling two warehouses with distinct logic for stock availability and delivery time - building a dynamic "deal of the day" module - optimizing performance on PrestaShop 1.6, a platform not known for being lightweight - adapting the design and UX for mobile and tablet - giving the client's team a simple panel for managing promotions and stock

Scope and delivered functionality

Frontend and UX/UI - Premium visual design tailored to the home décor category - Category layout built to handle a wide product assortment - Mobile responsiveness, largely rebuilt from the ground up — typical for a PrestaShop 1.6 theme - A "deal of the day" module with automatic, time-based promotion switching

Backend and e-commerce - Full PrestaShop 1.6 implementation, including category, filter, and product-variant configuration - Two-warehouse support with logic for stock availability and delivery time - Integrations with marketplace and retail partners: - Carrefour Marketplace feed - Tesco / Ezakupy feed (CSV/XML) - Empik Marketplace API - Automated product feed generation - Scheduled (cron-based) stock update jobs - Performance improvements for a large product catalog: caching, indexing, pagination

"Deal of the day" module - Dynamic offer banner - Countdown timer - Manual and automatic product rotation logic - Featured placement within category listings

SEO and performance - Core Web Vitals optimization — a genuine challenge on PrestaShop 1.6 - Faster load times through caching (memcached/Redis-backed), template-level optimization, custom WebP image delivery, and CSS/JS minification - Structured data implementation: Product, Offer, and BreadcrumbList schema

Results

• Meaningfully faster load times. Page load time improved by roughly a third (~35%) despite the large product catalog.
• Automated retail feeds. Product data now flows automatically to Carrefour, Empik, and Tesco, cutting manual catalog maintenance.
• More engagement with promoted products, driven by the "deal of the day" module.
• Improved UX and stronger return-visit behavior.
• Reliable two-warehouse fulfillment, with accurate delivery-time information shown to customers.
• Stronger SEO visibility across product and category pages.
• Fewer errors tied to warehouse and inventory integration.
