SaaS-Based B2B Marketplace Development: Our Case Study

At The Brihaspati Infotech, we worked with a US client to build a centralized B2B marketplace platform where businesses can find, compare, and hire testing labs for unique project needs. Our web portal development team planned and delivered the on-demand service marketplace solution.

Here’s how we worked through it: 

Step 1: Project Requirements Analysis for B2B Marketplace Development

Before writing a single line of code, we mapped out the system architecture and defined user roles. The B2B marketplace platform needed to support multiple test labs, users, and admins.

Defined User Roles

• Users:  Search for labs, submit projects and track responses.
• Test Labs: Manage profiles, list equipment, and respond to project requests.
• Admins: Oversee platform operations, verify test labs, and configure system settings.

Selected Tech Stack

• Backend: Laravel (handles user management, data processing, and APIs).
• Frontend: Vue.js (creates a dynamic, fast user experience).
• Database: MySQL (structured storage for projects, users, and test labs).
• Search Engine: MeiliSearch (for typo-tolerant search and advanced filtering).
• Maps & Location: Google Maps API (for lab discovery and geolocation features).

We implemented a multi-tenant architecture, ensuring scalability and structured data management.

Step 2: Implemented User Authentication & Role-Based Access 

A multi-vendor marketplace platform means different users need different levels of access. We implemented role-based access control (RBAC) to ensure a smooth user experience.

• Custom authentication system with secure login, registration, and password recovery.
• Created dashboards tailored for each user type (Users, Test Labs, Admins).
• Deployed restricted access to features based on user roles.

Step 3: Created Advanced Test Lab Search & Filtering System 

During B2B web portal development, we built an intelligent search system with typo tolerance and location-based filtering to help users quickly find the right service provider.

• Developed a search system using MeiliSearch for:
  • Typo-tolerant search (users get results even with minor spelling errors).
  • Filtering by: Location, test types, accreditations, and equipment.
• Implemented Google Maps API to allow location-based lab discovery.
• Added custom sorting options (distance-based, rating-based, etc.).

Step 4: Enabled Project Submission & Management

Our client wanted project submission system to be simple yet comprehensive.

We designed a structured 4-step project creation form with:

• Project’s draft-saving functionality so users can resume later. 
• Live validation of inputs to prevent errors.
• Project tracking dashboard where users could view responses from test labs.

Test labs received project details and could respond directly with pricing or queries, streamlining communication and decision-making.

Step 5: Created Lab Profiles & Equipment Management

Each test lab needed a customizable profile to showcase its capabilities. 

We created a dedicated dashboard for test labs to:

• Manage profiles, accreditations, and equipment listings.
• Add multiple team members with controlled access.

Admin verification system was implemented to ensure data accuracy before profiles were published. This helped businesses make informed decisions based on verified lab credentials.

Step 6: Integrated Custom Engineering Calculators

During B2B web portal development, we found precision testing requires complex calculations.

We integrated a set of engineering calculators that allow users to enter test parameters and receive real-time results.

• Integrated SINE, RANDOM, Terminal Peak Sawtooth, and other calculators.
• Designed a dynamic UI for calculations, making it easy for users to generate test parameters.
• Backend logic that ensures high accuracy for large datasets.

This feature enhanced the B2B platform’s value by helping users determine test specifications without external tools.

Step 7: Created Admin Panel for B2B Marketplace Development 

A centralized admin dashboard was essential for managing the multi-vendor marketplace platform.  

• Created centralized dashboard for admins to:
  • Manage and moderate test labs, users, and test types.
  • Configure accreditations & certifications.
  • Export reports & analytics for tracking platform performance.

This ensured smooth platform operations and a controlled ecosystem for all users.

Step 8: Implemented Security & Performance Enhancements

Security and speed were our top priorities throughout B2B web portal development. Also, the multi-vendor marketplace platform deals with sensitive project data.

Security Measures:

• SSL encryption for secure transactions.
• Role-based access controls to restrict sensitive data.
• API rate limiting to prevent abuse.

Performance Optimization:

• Caching search queries to reduce load times.
• Lazy loading images to improve page speed.

These measures enhanced reliability and protected user data for B2B platform development.

Step 9: Testing & Deployment

The multi-vendor marketplace platform needed rigorous testing to ensure seamless user experience and drive performance. 

Testing Process: 

• Conducted cross-browser & device testing to find and fix UI inconsistencies.
• Implemented A/B testing on critical UI elements to refine the user experience.
• Used agile development to incorporate client feedback iteratively, ensuring fast turnarounds.

Final Deployment:

• Launched on AWS for scalable hosting.
• Used Cloudflare for added security & faster loading times.

Our B2B web portal development required comprehensive and dedicated IT resources. From managing multiple roles to implementing intelligent search and real-time calculations, every feature was designed to create a seamless experience for vendors and their customers.

The result? A powerful, multi-tenant SaaS platform where users, test labs, and admins can efficiently collaborate, manage projects, and streamline operations.

Challenges in B2B Marketplace Development

Our SaaS-driven B2B platform development faced several technical hurdles. Here’s how we effectively addressed them:

1. Implementing Multi-Role Functionality

The B2B platform development required three distinct roles (Prospect, Test Lab, and Admin), each with controlled access.

• Implemented Role-Based Access Control (RBAC) to restrict unauthorized actions dynamically.
• Used middleware authentication for secure API-level permissions.
• Designed separate dashboards to ensure role-specific experiences.

2. Handling Soft Deletes & Data Consistency

We observed that users could delete and re-register accounts, leading to data inconsistencies.

• Used Laravel’s Eloquent ORM to keep deleted data hidden but restorable.
• Enforced email uniqueness to prevent duplicate accounts.
• Handled data dependencies when accounts were removed.

3. Integrating Complex Features

The B2B marketplace platform required typo-tolerant search, location-based filtering, and complex calculations.

• Integrated MeiliSearch for fast, error-tolerant searches.
• Used Google Maps API for precise lab locations & filtering.
• Optimized the calculators to process large datasets with minimal latency.
• Built a four-step project submission form with auto-save for user convenience.

By overcoming these challenges, we delivered a high-performance B2B online marketplace within an estimated time.
