Helping sellers manage listings, leads, and performance in one place
This project involved designing a seller dashboard for a used vehicle trade platform, focused on helping individual sellers and dealers efficiently manage their inventory and buyer interactions.
The dashboard acts as the operational core of the platform — enabling sellers to list vehicles, track inquiries, monitor ad performance, and communicate with potential buyers, all from a single interface.
Context
Selling vehicles online can quickly become overwhelming. Sellers often juggle multiple active listings, repeated buyer inquiries, and performance tracking across different ads.
The goal was to design a clear, structured dashboard experience that reduces friction and helps sellers focus on closing deals rather than managing tools.
The Challenge
- • Multiple active listings to manage
- • Timely responses impact conversion
- • Need for performance visibility
Business Goals
- Increase listing quality and completion
- Improve seller responsiveness to inquiries
- Encourage continued engagement from sellers
- Create a scalable foundation for future seller tools
User Goals
- Easily manage all vehicle listings
- Track buyer inquiries and responses
- Understand how listings are performing
- Feel confident and in control of the selling process
Understanding the Users
Instead of traditional personas, I focused on behavior-driven seller types.
The Individual Seller
Selling one or two vehicles and wants a simple, guided experience.
The Power Seller / Dealer
Managing multiple listings and needs efficiency, visibility, and speed.
The First-Time Seller
Needs clarity, reassurance, and guidance throughout the process.
Design Principles
Clarity over clutter
Sellers should immediately know what needs attention.
Action-first design
Every screen should clearly suggest the next step.
Visibility builds confidence
Performance data should be easy to understand.
Designed to scale
The dashboard should grow with seller needs.
Process
1. Defining Core Seller Jobs
I mapped the key jobs sellers hire the platform for: create/manage listings, respond to inquiries, monitor performance, and edit/relist.
2. Information Architecture
The dashboard was structured around seller intent: Overview, Listings, Inquiries, Performance.
3. User Flows & Wireframes
Adding a new vehicle, editing details, responding to buyers. Wireframes focused on reducing steps.
4. Visual & Interaction Design
UI emphasizes clear tables, card layouts, strong hierarchy for status/actions, and consistent controls.
Final Design Highlights
Seller Overview Dashboard
A high-level snapshot showing active listings, new inquiries, and performance indicators. Designed for quick daily check-ins.
Listings Management
View all vehicles at a glance, edit/pause/relist easily, and track status changes. Bulk-friendly layouts support power sellers.
Buyer Inquiries & Leads
A centralized inbox allows sellers to respond quickly, track conversation status, and avoid missing leads.
Performance Insights
Simple metrics help sellers understand views, conversion to inquiries, and optimization needs.
Quality Assurance & Certification
Mechanic Verification Workflow
To build trust in the marketplace, we designed a dedicated interface for certified mechanics. This tool allows them to perform comprehensive quality checks directly on the platform.
- ✓150-Point Inspection: A digital checklist ensuring no detail is overlooked (Engine, Transmission, Exterior, etc.).
- ✓Real-time Uploads: Mechanics capture and upload photos of defects instantly.
The "Velocegrade Certified" Badge
Once a vehicle passes the inspection, it receives a verified certification badge. This acts as a signal of quality to buyers, differentiating premium inventory from standard listings.
The certificate is auto-generated and attached to the listing, providing buyers with a downloadable, transparent report of the vehicle's health.
Impact
Clear Workflow
The dashboard created a clear, usable selling workflow.
Centralized Management
Sellers could manage listings and messages from one place.
Future Ready
The foundation supports future features like pricing insights.
Empowering Sellers
"A good marketplace doesn’t just connect buyers and sellers — it empowers them. This project reflects my approach to designing practical, scalable, and user-centered product experiences."
