Budget: ₹37,500 – ₹75,000 INR
We are looking for an experienced full-stack developer or team to build a custom, scalable B2B platform from scratch.
This is NOT a basic website. It is a business-critical system that will manage:
RFQs (Request for Quotes)
Quotes Orders Purchase Orders Shipping Invoices Payments →= Taxation
Internal operations currently handled via QuickBooks + manual workflows
No WordPress / WooCommerce / low-code builders
Fully custom-built, production-grade system only
Key Objectives
Replace fragmented tools (QuickBooks + Excel + manual tracking)
Automate business workflows end-to-end
Build a clean, modern, high-performance UI
Ensure scalability and modular backend architecture
Frontend Requirements
Modern, premium UI (NO generic or AI-generated layouts)
Fully responsive (mobile + desktop)
SEO-friendly structure
Features:
Product catalog (display only, NO pricing)
Multi-product RFQ (quote request system)
“Can’t find product?” custom request form
Shipment tracking:
Search via Name / Business Name + Invoice/Order Number

Core Workflow (CRITICAL)
System must replicate and improve this flow:

Vendor ships:
Send invoice
Convert PO → Bill
Customer pays → mark invoice as Paid
Repeat Orders
Skip quote step
Auto-generate invoice
Auto-fill all details
Keep invoice in “Pending Approval”
Numbering Logic (Important)
Quote Number = Invoice Number (must match exactly)
PO Number = Derived from invoice number with prefix (e.g., PO-XX-1001)
Invoicing System
Manual pricing entry
Auto invoice numbering
Convert quotes → invoices
Send via email (SMS/WhatsApp API-ready)

Reporting layer
Backup system
Taxation System
Track invoices, payments, refunds

Payment integrations
Shipping APIs
