Understanding why the product wasn’t being used.

Before redesigning screens, we needed to understand why a product built to simplify procurement was being actively avoided.




Through user interviews, operational audits, and live order shadowing, we uncovered a pattern: most high-value workflows were happening outside the app. Orders, payments, invoices, and credit were all being managed manually — turning the platform into an incomplete catalogue, not a system.

  • Large and credit-based orders bypassed the platform entirely

Once the core blockers were mapped, we focused on the highest-leverage opportunity: improving how buyers discover products, suppliers, and value.

Discovery wasn’t just about search — it was about confidence, comparison, and clarity.

Lack of unified payments were the single biggest blocker for user adoption.

Cash on delivery, offline invoices, manual credit approvals, and post-order chaos meant Watermelon had no real control over its own transactions.



This section shows how we redesigned payments not as a feature — but as an operating system.
