Could you build this?
No Manufacturing ERPs require extensive domain-specific business logic including complex multi-level Bills of Materials (BOM), MRP II scheduling algorithms, inventory valuation, and regulatory audit compliance that took years of specialized domain engineering.
What it would actually take: A real manufacturing ERP needs a robust relational database backend (PostgreSQL) modeling recursive hierarchical BOM structures, inventory ledgers with FIFO/LIFO tracking, work orders, routing, and shop floor scheduling. The challenging parts are the MRP calculation engine (handling lead times, safety stocks, lot sizing, and capacity constraints) and seamless accounting integration. Building this demands seasoned ERP software architects and deep industrial manufacturing domain specialists.
