Comprehensive B2B Supply Chain Platform

B2B Commerce & Distribution Management Platform

Project Overview

I am looking to develop a scalable B2B Commerce & Distribution Management Platform that connects the complete supply chain:

Manufacturer → Distributor → Wholesaler → Retailer

The objective is to create one integrated platform for B2B product ordering, wholesale transactions, payments, credit management, digital billing, transportation, stock management and business reporting.

The system should automate pricing, order processing, payment calculations, credit/ledger management, transaction records and transportation options.

1. User Types

The platform will support four primary business users:

* Manufacturer
* Distributor
* Wholesaler
* Retailer

Each user type should have a dedicated dashboard and role-based features.

2. Retailer → Wholesaler Ordering

Retailers should be able to:

* Browse products available from wholesalers
* View product details, pricing and availability
* Add products to cart
* Place orders directly with wholesalers
* View order status and history
* View transaction details
* Track paid, pending and credit transactions

Wholesalers should be able to:

* Receive retailer orders
* Accept, modify or reject orders
* Update order status
* Manage pricing and discounts
* Process and fulfil orders

3. Automated Pricing & Billing

The system should automatically calculate:

* Product quantity
* Product price
* Discounts
* Applicable taxes
* Transportation charges
* Current order amount
* Previous outstanding amount
* Total payable amount
* Credit amount

Before final confirmation, users should see a clear Order Summary / Digital Bill.

4. Payment Options

The platform should support:

* UPI
* Bank / Account Transfer
* Credit

Wholesalers should be able to manage their UPI/bank payment details.

For credit transactions, the system should automatically calculate:

Previous Due + Current Due = Total Outstanding

The outstanding balance should be visible to both parties.

5. Credit & Digital Ledger Management

The platform should maintain a complete digital credit history between buyers and sellers.

Users should be able to view:

* Previous outstanding balance
* New credit transactions
* Payments received
* Remaining balance
* Payment dates
* Credit history
* Total outstanding amount

This should function as a digital B2B ledger/accounting record between businesses.

6. Transportation Management

Transportation should be integrated into the ordering workflow.

Users can select either:

Option A – Transportation Included

* Transportation cost is included in the order
* Wholesaler arranges delivery
* Transportation charges are included in the bill

Option B – Transportation Excluded

The retailer can arrange transportation separately through the platform.

The retailer should be able to:

* View available vehicles
* Compare vehicle options
* Select vehicle capacity
* View transportation charges
* Book/hire a vehicle
* Track delivery

7. Stock / Inventory Management – Optional Module

We also want to implement Stock & Inventory Management as an optional module.

Depending on the business requirement, Manufacturers, Distributors, Wholesalers and Retailers should be able to manage:

* Available stock
* Stock-in / stock-out
* Product quantities
* Low-stock alerts
* Inventory history
* Purchase and sales stock
* Warehouse/stock locations
* Stock adjustment

The inventory module should be designed so that it can be enabled or disabled depending on the user’s business type and requirements.

8. Business Dashboard & Reports

Retailers, Wholesalers, Distributors and Manufacturers should have role-specific dashboards showing:

* Monthly purchases/sales
* Total sales
* Total purchases
* Order history
* Transaction history
* Credit transactions
* Outstanding payments
* Paid transactions
* Pending payments
* Transportation expenses
* Stock/inventory summary
* Periodic business reports

9. Transaction Management

Every transaction should maintain a complete digital record, including:

* Order ID
* Buyer/Retailer
* Seller/Wholesaler
* Products
* Quantity
* Product price
* Discount
* Tax
* Transportation charges
* Payment method
* Paid amount
* Credit amount
* Previous due
* Current due
* Total outstanding
* Transaction date
* Payment status

Users should be able to access their complete transaction history at any time.

10. Admin Panel

A powerful web-based Admin Panel should be developed to manage:

* Users
* Manufacturers
* Distributors
* Wholesalers
* Retailers
* Products
* Categories
* Orders
* Transactions
* Payments
* Credit accounts
* Transportation
* Vehicle providers
* Stock/inventory
* Commissions/platform fees
* Reports
* Notifications
* Platform settings
* User verification and account management

11. Expected Platforms

The platform should be developed for:

* Android App
* iOS App
* Web Application
* Web-based Admin Panel

The architecture should be scalable so additional modules and business categories can be added in the future.

* Understand the complete business workflow before development
* Create a professional UI/UX design

* Implement transportation integration
* Implement optional stock/inventory management
* Develop APIs and integrations where required
* Provide proper testing and bug fixing

13. Future Scope

The platform should be built with future expansion in mind, including:

* Wholesaler → Retailer ordering
* Multi-level B2B commerce
* Advanced inventory/warehouse management
