Context

Lulubuy is an e-commerce retailer bridging suppliers and global marketplaces. The core is a backend API connecting supplier systems to e-commerce platforms — orders are received and validated by suppliers, then products move through Lulubuy's warehouses for B2B or directly to end-customers for B2C.

Challenge

  • Align business, marketing and engineering on product requirements across very different surfaces.
  • Maintain consistency across a warehouse mobile app, ERP, website and SaaS.
  • Scale the design output as the product family grew over seven years.

Key decisions

— Why, not just what.
DECISION /01

Warehouse mobile app, not desktop

Operators worked on the floor. Mobile-first with strong batch actions matched the real workflow and cut time per order.

DECISION /02

Single design system across all products

Five products with overlapping users (operators, managers, customers) needed a shared visual and component language to keep cognitive load low.

DECISION /03

Improved user management in operations tools

Tracking operator output was needed to coach the team and improve double-check workflows for managers.

Learnings

/01

Operational tools live or die on small workflow details — observe before designing.

/02

A design system pays back the moment you have two products, not five.

/03

Long-tenure on a product builds the context that makes good decisions cheap.
