Selected Work

Every integration we build runs in production — handling real orders, real inventory, and real money. Here's what that looks like.

Case 01

Multi-Supplier Inventory Sync for E-Commerce

Client
Lascava
Industry
E-commerce / Retail
Live since
2013

Challenge

Lascava sells products from multiple European manufacturers, each with their own inventory system and API. Customers need to see accurate, real-time availability across all suppliers — including every size and color variant. Stock changes constantly, and selling an item that's no longer available means lost trust and costly cancellations.

What We Built

Custom integration layer connecting to each supplier's API, normalizing different data formats into a unified product catalog

Real-time inventory aggregation: combined availability across Lascava's own warehouse and all supplier warehouses

Unified size/color matrix per product — one complete view, not fragmented data

Payment gateway and shipping API integrations for end-to-end order processing

Case 02

AI-Powered Price List Processing for HVAC Retailer

Client
Eco Service
Industry
HVAC / Retail
Type
AI Automation

Challenge

Multiple suppliers send price lists in different formats — Excel files, PDFs, custom exports. A full-time employee spent every working day manually updating prices and stock levels. Formats changed without warning, new products appeared, and human errors caused pricing discrepancies.

What We Built

AI-powered processing pipeline that accepts price lists in any format

The AI agent identifies document structure, maps products to the existing catalog, and updates prices and availability automatically

Smart matching: handles variations in product naming, SKU formats, and column structures across different suppliers

Exception handling: flags uncertain matches for human review instead of guessing

Results

1 FTE freed
Position redirected from data entry to higher-value work
Minutes, not days
Price and stock updates happen automatically
Fewer errors
Pricing discrepancies from manual copy-paste eliminated
Self-adapting
System handles format changes without reprogramming
