How JoulesLabs Built iVendorz, Bangladesh’s First B2B Marketplace Platform
Digitizing vendor discovery and sourcing for a nation of 170 million people
iVendorz was developed to solve one of Bangladesh’s biggest business challenges: the absence of a dedicated B2B marketplace connecting buyers and verified local vendors.
JoulesLabs partnered with the iVendorz team to design and build a comprehensive B2B platform that brings verified suppliers online, giving every business a digital identity and making vendor discovery effortless for buyers.
Challenges & Solutions
Problem Statement
Bangladesh’s B2B ecosystem operated largely offline. Buyers relied on referrals and manual searches, while vendors struggled to establish an online presence.
Key problems included:
- No centralized vendor database or sourcing platform
- Manual quotation and comparison processes
- Vendors without websites or digital visibility
- High communication friction between buyers and suppliers
The objective was to build a secure, scalable platform that allowed buyers to discover vendors, send RFQs, and compare quotations efficiently, while helping vendors build digital storefronts to showcase their products and expertise.
Approach & Solution
JoulesLabs approached the project with a clear focus on usability, scalability, and market relevance.
Research and Discovery
We conducted extensive research into global and regional B2B marketplaces such as Alibaba and IndiaMart, identifying local gaps in vendor onboarding, verification, and buyer workflows.
Platform Design and Engineering
- Built a user-friendly marketplace with advanced vendor search and filtering
- Created automated RFQ matching to connect buyers with relevant suppliers
- Designed personalized subdomains for each vendor to function as their own micro-website
- Developed a verification system to ensure vendor credibility
- Enabled vendors to manage their products, credentials, and client inquiries directly from their dashboards
Technical Execution
The system was architected for scale using cloud-based infrastructure and modular service components, allowing the platform to grow as the vendor base expanded.
Impact
iVendorz is poised to become Bangladesh’s largest B2B vendor network, transforming how businesses source products and services.
Key outcomes and milestones include:
