CLIENT CHALLENGES
-
Stock & pricing desynchronization risks. The client managed inventory in PC-Market ERP. Concurrent online and offline sales created a high risk of overselling out-of-stock items without real-time sync.
-
Food retail specifics. Complex product requirements including weight-based items (+/- 100g step), hybrid items (grams in warehouse, sold by piece), and mandatory Polish packaging deposit fees (kaucja) calculated as separate line items.
-
Local payment & shipping integration. To ensure high trust and seamless conversion among Polish shoppers, the platform required native integrations with PayU (BLIK, card payments, instant transfers) and InPost (Paczkomaty lockers and courier delivery).
-
Conversion and UX bottlenecks. Need for frictionless customer onboarding (1-click checkout with auto-saved profiles), average order value (AOV) growth drivers, and automated catalog visual management.
-
Ad campaign readiness. Strict requirements from the marketing team to prepare site architecture, feed generation, event tracking, and landing pages for Google Shopping and Meta Ads campaigns.
OUR SOLUTION
-
Bi-Directional PC-Market ↔ WooCommerce Integration (Every 15 min)
- We engineered an automated bi-directional data exchange between PC-Market ERP (Pcm2www PRO) and WooCommerce via FTP/XML and standard WooCommerce REST API:
- PC-Market → WooCommerce: Stock and price updates run via cron every 15 minutes, mitigating overselling risks. Imported 500+ initial SKUs.
- WooCommerce → PC-Market: Orders are automatically transmitted to the ERP for instant fulfillment. Implemented order editing in WooCommerce for managers to adjust quantities when weight discrepancies occur.
-
Grocery Retail Engineering & Localization
- 3 Product Types: Standard (per piece), Weight-based (customizable +/- step in admin, default 100g), and Hybrid (stock reserved in grams when purchased per piece).
- Automated Packaging Deposit (Kaucja): Triggered by PC-Market flags, the system automatically adds kaucja as a separate line item in the cart, checkout, emails, and admin orders, scaling with item quantity.
- PayU & InPost Integration: Integrated PayU payment gateway (including BLIK) and seamless InPost shipping selection (Paczkomaty parcel lockers and courier) directly into the checkout flow.
-
5 Conversion-Focused Features
- Quick Purchase & Onboarding: Instant 1-click checkout for registered users and streamlined registration for new buyers with auto-saved delivery profiles.
- Dynamic Free Shipping Progress Bar: Interactive cart/checkout widget showing remaining amount for free shipping with an editable threshold in the admin panel.
- Automated Visual Badges: Smart labels ("New", "Bestseller", "Sale", "Last Item") with automated expiry handling via Cron to prevent database bloat.
- Smart Recommendations (Cold-Start Hybrid Model): Category-based mapping at launch (e.g., suggesting cookies when viewing tea) with underlying architecture for future self-learning algorithms.
- Auto-Centering & Image Scaling: Smart image containers maintaining clean catalog grids and aspect ratios regardless of raw uploaded photo dimensions.
-
Marketing-Ready Architecture
- We fully configured the platform according to the marketing team's technical specifications: setup structured data, Google Merchant Center feeds, enhanced e-commerce tracking events, and optimized page speed for high-converting ad traffic.
SCALABILITY
The robust system architecture easily supports ongoing product expansion and traffic scaling. The 15-minute PC-Market sync operates reliably under heavy loads, while administrative controls allow staff to manage promo thresholds, badges, and recommendation mappings without developer assistance.
