Full-Stack Developer for Jewelry ERP SaaS (Multi-tenant)
Budget: ₹75,000 – ₹150,000 INR
I am looking to build a professional-grade, multi-tenant B2B SaaS application tailored for the Indian jewelry market. This is an ERP/Billing solution that requires high precision in financial calculations and strict data isolation between business users.
The Vision:
A "Walled Garden" SaaS where every jeweler gets their own private workspace. The system must support complex jewelry business logic (Gold/Silver weight tracking, Custom job work, and daily market debt management) with a professional-grade invoice generator and automated accounting ledger.
Key Requirements:
Multi-Tenant Architecture: Design a robust database structure (Firebase/Firestore) that enforces strict data isolation for each business client.
Business Logic & Math:
Implementation of precise financial engines for jewelry inventory, weights/rates, and multi-bill debt management (auto-split ledger logic).Automated Document Generation: Build a highly professional PDF/HTML print engine for invoices and account statements, including dynamic QR code integration for UPI payments.
SaaS Infrastructure:
Develop a scalable user registration, business profile customization (logos/branding), and a robust subscription model (integration with Razorpay/Cashfree webhooks). Security & Compliance: Implement server-side security rules that prevent any cross-tenant data access.
Testing:
This is a financial tool—mathematical accuracy is the highest priority. I require a project lead who emphasizes automated unit testing for all financial calculations.
Preferred Stack:
Frontend: React.js / Next.js (clean, fast UI).
Backend: Firebase (Firestore, Auth, Functions).
Infrastructure: Multi-tenant database design and strict server-side security.
What I am looking for:
A developer/architect with a proven track record in B2B SaaS.Someone who understands that this is an accounting tool—they should ask questions about how tax (GST) and financial records are handled before starting.
Commitment to high-quality code, security, and automated testing.
To apply, please provide:
A link to a similar multi-tenant SaaS application you have built from scratch.
An explanation of how you approach data isolation in Firestore (e.g., how you ensure Company A cannot access Company B’s data).
Your estimated timeline and approach to the initial architectural design phase.
Note on Budget: The project budget is currently flexible. I am looking for the most qualified partner to build a robust, secure, and mathematically precise ERP system. Please submit your project proposal and quote based on the scope provided. I am open to discussing the pricing structure once I understand your technical approach and development roadmap.
