ERP-Connected Inventory App MVP

I need a lean MVP of an inventory management app that can plug straight into our existing ERP. We have not locked ourselves into a single back-end yet, so the build should be flexible enough to link via API to SAP, Oracle, or Microsoft Dynamics once the decision is final.

Core functions must include real-time stock updates flowing both ways between the ERP and the app, reliable barcode scanning, and an in-app dashboard for reporting and analytics. The scanner has to read QR, UPC and EAN codes out of the box.

I’m expecting a clean, mobile-friendly interface, solid database design, and concise documentation that lets my internal team scale the codebase after the MVP is proven. Please outline your recommended tech stack, estimated timeline, and any past work that shows you can get an ERP-connected prototype into production quickly.
