Project thinking
From brief to working system
The decisions behind the interface matter as much as the final screen.
A specialist catalogue for two audiences
Heating, cooling, ventilation and energy-efficiency products needed to remain understandable to both consumers and professional installers.
- Consumer and professional audiences
- Technical product categories
- Content that supports selection
Bulk management and commercial feeds
The management of many products, prices and availability was organised to reduce manual work and support distribution through channels such as Skroutz.
- Bulk product handling
- Skroutz XML feed
- Pricing and stock
Payments and shipping for complex products
Payment methods and shipping rules were connected to weight and volume so checkout can better reflect the real order.
- Multiple payment methods
- Weight- and volume-based calculations
- A clear checkout journey
Content and operations on one foundation
Editorial content, analytics and order management were incorporated into the same OpenCart environment, supporting information, sales and measurement.
- Integrated blog
- Analytics
- Central order management
