B2B/B2C Marketplace & Procurement SaaS
End-to-End MVP Product Design for Quanti.dk
Bridging tender and group-buy in one SaaS
🗂️ Overview
Quanti.dk is a B2B/B2C e-commerce platform designed to enable users to make group purchases or launch tenders for suppliers. It provides role-specific interfaces and dashboards for administrators, vendors, and customers. I needed a complete UX/UI solution to build a modern MVP that supports different market flows
Goal
Deliver a modern, role‑based MVP (Admin • Vendor • Buyer) that supports tenders for B2B and group‑buying for B2C

💥 Problem Statement
How might we give corporate buyers, vendors and everyday shoppers one web platform where they can create a tender, submit a bid, or complete a group-buy purchase in ≤ 5 clicks, while admins keep full oversight

💻 Process
Initial Audit & Design Alignment
I began with a quick audit of existing materials—wireframes, feature lists, market decks, and workflow diagrams. Based on that, I created a structured kickoff questionnaire covering business goals, role-based value, and timeline constraints. The insights helped define the product direction and guided all design decisions
Research — Competitor Analysis
After stakeholder interviews, I ran a focused competitor analysis, including a POP-POD matrix, feature comparison, and UI audit. This clarified the market landscape and helped prioritize MVP features and shape a realistic growth roadmap.
Research Summary
I consolidated all collected materials and stakeholder input into a clear vision of our target users and their primary pain points.
Corporate Buyer
Alex, 42
Head of Procurement at a 200-employee manufacturing firm. Owns tendering for raw materials; KPIs are savings and process transparency
Pain: Receives fragmented Excel price lists and PDF quotes from multiple suppliers; manual comparison takes hours. Launching a tender means 1–2 days of emails and approvals
Vendor
Lars, 39
Wholesale electronics seller serving EU markets; sales team of three. Wants to locate tenders quickly and submit bids with minimal friction
Pain: Typical B2B platforms require a 10-step onboarding (CSV templates, certificate uploads). After bidding he may wait weeks for feedback, missing live opportunities.
Consumer Buyer
Julia, 24
Digital marketer and active online shopper, attracted by group discounts and fast delivery
Pain: Group-buy sites rarely show the final discount or closing time, so she abandons the cart. Multi-page checkout flows add more drop-off ~40 %.
Role Based MVP Feature Matrix
I clarified the must-have MVP feature set for each user role, mapping every critical task to Corporate Buyers, Vendors, and Consumer Buyers so development can focus on the highest-impact workflows first
Role
Critical user flows to cover
Admin
Sign-in → Manage Products / Categories / Vendors / Buyers → Create & Moderate Tenders
Vendor
Register/Login → Portal Home → Submit Bid → Profile & Support
Buyer
Register/Login → Browse Catalogue → Add to Cart & Purchase → Orders → Profile & Support
Additionally, I laid out a phased design workflow—Discovery, Ideation, Prototyping, Validation, and Handoff—complete with milestones, deliverables, and timelines to keep the entire team aligned and the project on schedule
🗃️ Assumptions
1. Fragmented and time-consuming tendering: Corporate buyers currently juggle email threads, PDF quotes, and Excel price lists; manually comparing offers can consume an entire day and still lead to costly errors
2. Unclear path to the first bid: Vendors often abandon new B2B platforms because a 10-step onboarding (CSV uploads, certificates, tax forms) stands between them and submitting that critical first offer
3. Need for instant, transparent savings: Consumer buyers join group-buy pages expecting to see how much they will save and when the deal closes; if the discount meter or timer is unclear, they drop the cart within seconds
4. Admin overload on basic moderation: Operations managers spend an extreme time approving vendors, resolving disputes, and hunting for status data spread across tools, leaving little capacity for insight-driven improvements

🚀 Solution
To address key pain points, I worked closely with the PM and engineers, validated technical constraints, and aligned with stakeholders through an iterative plan and feedback loops
Streamlined Tender Wizard: A guided 4-step flow that lets corporate buyers launch a tender without spreadsheets, cutting setup time from hours to minutes
Instant Bid Path for Vendors: A 3-steps Express Bid form and light-touch onboarding, enabling suppliers to place their first offer in under 10 minutes
Transparent Group-Buy Checkout: Real-time discount meter and closing timer so shoppers always know savings and deal status, reducing cart abandonment
Unified Admin Dashboard: One control panel for approvals, dispute resolution, and live tender metrics—turning routine moderation into one-click actions

🏗️ Wireframing — Role-Based Low-Fidelity Prototypes
The team started with a rough low-fi mockup that lacked detail and had UX gaps. After auditing it, I got stakeholder approval to rebuild from scratch. I designed clear, task-focused flows for Admin, Vendor, and Buyer roles, which helped align logic early and speed up the move to high-fidelity design
🚧 Design Handoff
As wireframes progressed, I created a lightweight UI kit in Figma with colors, typography, spacing, and components. It kept visuals consistent, sped up UI work, and helped developers build faster
I collaborated closely with the front-end team to implement the UI, holding regular walkthroughs to check tokens, states, and edge cases. End-of-sprint reviews ensured the build matched the prototype, reducing visual debt and QA fixes

📊 Outcome
- ↓ 30 % vendor‑onboarding time
- ↑ checkout clarity → boosted purchase-completion rate by 15 %
Next Step
Post-launch, completed tenders increased by 15%, confirming readiness for the next phase. The upcoming focus includes a real-time analytics dashboard and in-app support chat to boost visibility for buyers and reduce friction for vendors
