About Our Client
Our client wanted to modernize how wholesale businesses discover products, manage inventory, evaluate market pricing, and coordinate sourcing activities.
Traditional wholesale operations often rely on spreadsheets, WhatsApp conversations, manual price comparisons, and fragmented supplier relationships. Sellers lacked visibility into competitor pricing, inventory performance, and procurement opportunities, while platform operators needed a way to verify sellers and maintain a trusted supplier network.
To solve these challenges, Space-O developed PrivateShopper, a B2B marketplace that combines seller verification, product catalog management, inventory management, competitive pricing intelligence, product sourcing, procurement workflows, and financial reporting into one platform.
How We Built a Custom B2B Marketplace Platform
The client partnered with Space-O Technologies to build a centralized B2B marketplace platform capable of managing seller onboarding, product sourcing, inventory operations, pricing intelligence, procurement activities, and marketplace reporting. To support the client’s vision, we designed and developed six core modules that power the entire PrivateShopper ecosystem.
Seller Verification & Vendor Management Platform
Requirement:
The client needed a structured onboarding process to verify businesses before granting marketplace access. They wanted to build a trusted supplier network platform where only approved sellers could access products, pricing data, and sourcing opportunities.
Solution:
We developed a centralized vendor management platform that allows businesses to submit applications, complete onboarding requirements, and gain access to the marketplace after approval. Administrators can review applications, approve verified sellers, reject submissions, and maintain a trusted verified seller network through a dedicated user management dashboard.
Wholesale Product Catalog & Inventory Management Platform
Requirement:
The client required a centralized solution for managing product listings, inventory visibility, stock availability, and marketplace inventory across multiple sellers.
Solution:
We built a robust product catalog management and inventory management platform that allows sellers to add products, manage inventory, monitor stock levels, track inventory value, and maintain accurate product information. The platform provides complete visibility into wholesale inventory management operations through a centralized seller dashboard.
Product Sourcing & Procurement Management Platform
Requirement:
The client wanted to simplify sourcing activities and create a structured process for connecting sellers with procurement opportunities and sourcing agents.
Solution:
We developed a product sourcing platform and procurement management platform that enables sellers to participate in proxy shopping trips, discover sourcing opportunities, connect with procurement agents, and streamline product acquisition workflows through the marketplace.
Competitive Pricing Intelligence & Market Analysis Platform
Requirement:
Sellers needed access to market pricing insights to evaluate competitors, optimize pricing strategies, and improve profitability.
Solution:
We developed a competitive pricing intelligence module that enables verified sellers to compare competitor listings, review market pricing trends, analyze pricing performance, and make informed pricing decisions. The platform helps businesses improve margins through data-driven pricing analysis and competitor benchmarking.
Sales Tracking & Financial Reporting Platform
Requirement:
The client wanted sellers and administrators to track revenue, profit margins, inventory performance, and business growth through a single reporting system.
Solution:
We developed a centralized financial reporting and sales tracking system that provides visibility into revenue, profit, sales activity, inventory value, and business performance. Sellers can monitor operational performance while administrators gain platform-wide financial insights.
Marketplace Analytics & Seller Performance Monitoring
Requirement:
The client required a reporting ecosystem capable of measuring marketplace growth, product engagement, seller activity, and operational performance.
Solution:
We built a comprehensive marketplace analytics and seller performance monitoring system that tracks product views, seller activity, inventory performance, sourcing engagement, and platform growth. Administrators can evaluate marketplace health while identifying top-performing sellers and products.
