SEP Feestartikelen has been a go-to destination for party supplies in the Netherlands for over 60 years.
To future-proof the brand, owner Dennis Sep set out to create an e-commerce experience that matched the warmth and vibrancy of the physical store—while integrating smoothly with the point-of-sale system and keeping the customer experience at the heart of it all.
Bumpp created a colorful, user-friendly webshop that captures SEP’s unique store experience and festive brand personality. The platform integrates with Lightspeed Retail X for real-time syncing of inventory and payments, and guides customers from inspiration to checkout with ease.
The new platform seamlessly connects SEP’s physical store with its digital presence, offering customers a shopping experience that’s just as cheerful online as in the physical store.
The brand’s personality comes through in every detail—from vibrant visuals to simple navigation and inspiring product displays. Customers can now shop online without losing SEP’s personal feel.
Real-time integration with the POS system ensures smooth operations, keeping inventory, payments, and customer data perfectly aligned.
The platform supports long-term growth with a future-ready foundation that blends tradition and technology, helping SEP stay relevant for the next generation of party planners.
