I have a fairly complex requirement - to build a bespoke cloud-based ERP system for deployment in a specific industry. At the core is MRP inventory management; coupled to an approval and requisition system and procurement and work order elements. Accessible to clients and vendors via a web front end, similar feel to Maximo or COUPA. I have a clear idea on the required functionality, but the underlying mechanics I am open to discussion, AWS is a suggestion. I'd need to understand your capability and previous work and also explain the project in greater detail.
