Migrating from SAP to a Custom ERP for Chennai Manufacturers
For Chennai manufacturers reviewing SAP costs: where a custom ERP fits, what must stay compatible with OEM customers, and a low-risk migration sequence.
Chennai's suppliers were early adopters of SAP, encouraged by their customers. Years later the picture is mixed: finance and purchasing run well, while the shop floor relies on bolt-on tools and spreadsheets, and each plant addition means more licences.

What must not break
EDI with customers, label formats, traceability and statutory reporting. These are interfaces and outputs, and a new system can reproduce them exactly.
