Exclusive B2B platform for certified diamonds and gemstones
Loehn Digital developed for KGK Suisse not just an online shop, but an exclusive B2B platform for certified diamonds and gemstones
The shop combines a premium presence with deep APPlus ERP integration, controlled B2B access and specialised product search for professional buyers in the watch and jewellery industry.
Starting point
KGK Suisse stands for Swiss diamantaire heritage since 1918 and operates in a market where trust, provenance documentation and precision are decisive. A conventional online shop would not have been enough. The platform had to become an exclusive B2B sales tool that grants access only to verified business customers while addressing international audiences in German, English and French.
The challenge was combining premium branding, complex diamond data, ERP synchronisation and a protected purchasing process. Buyers need to find products quickly by professional criteria, while stock levels, customer data and orders remain cleanly connected to the APPlus system. The custom website addresses these requirements seamlessly.
Solution
Custom theme
Loehn Digital developed a fully custom theme that reflects the brand’s calm, premium visual language while keeping navigation deliberately clear. The shop was not designed as open mass-market commerce, but as a digital B2B platform for qualified enquiries, regular customers and recurring purchasing processes.
APPlus ERP integration
At the core of the technical implementation is APPlus ERP integration. Product data, stock levels, customer data and orders are synchronised between shop and ERP. This creates a reliable data foundation for sales, customer service and procurement — without manual duplicate maintenance.
Controlled B2B onboarding process
The onboarding process ensures that only verified business customers gain access to sensitive product areas:
- Request access
- Complete form
- Apply for customer account
- Customer verification (manual KGK process)
- Activate customer
Specialised diamond search
The product search translates industry-specific criteria into user-friendly filters and makes it easier to research suitable stones — by carat, clarity, colour, cut and other professional parameters.
