User Research & Persona Development
User Research
-
To ground the design in real needs, we conducted user research with potential bulk buyers in the fitness and nutrition industry. From interviews and surveys, we identified three primary user personas, each with distinct motivations, pain points, and goals:
Insights
All personas highly value pricing transparency (knowing their cost and margin at a glance) and trust (verification that products are authentic). They also desire efficiency in placing repeat orders and flexibility in how orders are fulfilled (either receiving goods themselves or shipping directly to someone else). These insights guided our design priorities and feature set.
User personas
Information Architecture & User Flow
With the personas’ needs in mind, we structured the app’s information architecture to prioritize bulk purchasing and trust. The app’s main navigation is simple and task-focused, with key sections for Shop, Orders, Scan/Verify, and Account/Rewards. This ensures users can quickly find products, place orders, verify authenticity, and track their rewards or orders.

This ensures users can quickly find products, place orders, verify authenticity, and track their rewards or orders.
Trust & Authentication Features
scanning function is integrated throughout the app. A “Scan” button (accessible from the home screen or navigation) lets users scan a product’s barcode or QR code. This serves two purposes:
1. Product Authentication: After receiving inventory, the buyer can scan an item’s code to verify it’s authentic and from the official supply (the app will confirm authenticity or flag issues).
2. Quick Reorder: Optionally, the user can scan an empty product package to quickly find that item in the app for reordering. This dual-use of scanning streamlines reorders and builds trust in product genuineness.

Outcomes & Impact
