Complete Warehouse Management System Development

I need a production-ready Warehouse Management System that covers the full life-cycle of inventory from receipt to shipping. The platform must track stock in real time, guide efficient order picking and packing, and generate the documents and carrier labels required at dispatch. Tight, reliable links with the rest of my tech stack are critical. The WMS has to exchange data seamlessly with our ERP, push live availability and order statuses to our e-commerce storefronts, and stay synchronised with broader supply-chain tools so purchase orders, ASN’s, and carrier events flow automatically. API endpoints or standard connectors to achieve this are essential. Key deliverables • Web-based WMS application with user, role, and location management • Core modules: inventory tracking, order fulfillment workflow, inbound shipping & receiving • Bi-directional integration bridges for ERP, e-commerce, and supply-chain systems (REST or SOAP; flat-file fallback acceptable) • Dashboard and reporting suite (stock accuracy, ageing, pick accuracy, OTIF) • Source code, deployment scripts, and concise technical documentation Acceptance criteria • All listed functions demonstrable in a staging environment with sample data • Data exchanged with at least one ERP and one e-commerce sandbox in real time • Zero critical bugs during a five-day test run; no workflow may dead-end a user Hand-off should include instructions for on-premise or cloud deployment and a quick-start guide for operators. Let’s agree milestones for architecture, MVP, integrations, QA, and final go-live so we both stay on schedule.
