ERP and warehouse management system development
Saksham Jain designs and builds custom ERP, warehouse management, attendance, HRMS and workflow systems end to end: database design, secure REST APIs, role-based permissions, automation, reporting and the user interface. He has 2+ years of experience delivering enterprise systems and ships them to production.
Works with technology companies, startups and product teams in India and internationally, remotely.
What you get
- Requirements, workflows and edge cases mapped before any schema is touched
- Data model and REST APIs with role-based access and permissions
- Workflow and automation engine for approvals and status changes
- Reporting views for operations teams
- Responsive, accessible admin UI built with Next.js, React and Tailwind
- Deployment, monitoring and documentation
Proof from shipped products
- PS Classes: One entitlement check (trial, purchased, admin) in a single middleware layer that every test and course endpoint routes through, instead of per-feature access logic.
- Trexind: Billing, booking and WhatsApp engines kept vertical-agnostic across clinics, restaurants and salons, with idempotent webhook handlers.
How the work runs
- Understand requirements. Business requirements, workflows, edge cases, and user journeys — before any UI or schema gets touched.
- Architect the solution. Database design, APIs, permissions, scalability, and deployment planning, mapped out before a line of production code.
- Build production systems. Type-safe APIs, reusable frontend, optimized backend, and testing — built for real load, not a demo.
- Optimize & ship. Performance tuning, monitoring, documentation, deployment, and maintenance until it's genuinely production-ready.

Common questions
What does a custom ERP or warehouse management system include?
A custom ERP covers the workflows your operations actually run: inventory or orders, approvals, user roles and permissions, reporting and integrations. Scope starts from your processes, not a template. Modules are built in priority order so the highest-value workflow goes live first and the rest follow in stages.
How much does it cost and how long does it take?
Indicative ranges for a custom ERP or warehouse management system are $1,100 to $4,700 (about ₹95,000 to ₹3.75 lakh) over 8 to 20 weeks, depending on user roles, workflows, integrations and the deadline. Treat this as a starting point: a fixed quote follows a requirements conversation, before any build starts, so the price reflects real scope.
