What is ERP (enterprise resource planning) in manufacturing?
ERP runs finance, purchasing, inventory and production planning on one system. See what manufacturing ERP covers, what it misses and how it links to MES.
Quick answer
ERP (enterprise resource planning) is business software that runs finance, purchasing, sales, inventory, production planning and often HR and maintenance on one shared database. In manufacturing it plans what to make, buys the materials and books the results. It sits above the shop floor, at ISA 95 level 4.

ERP explained
A manufacturing ERP typically includes finance and costing, procurement, sales and distribution, inventory and warehouse management, production planning with material requirements planning (MRP) and capacity planning, and quality and plant maintenance modules. Well known examples range from SAP S/4HANA, Oracle and Microsoft Dynamics 365 for larger companies to Odoo, ERPNext and many regional products for smaller ones. In India many smaller manufacturers start from Tally for accounting and add modules around it.
ERP is strong at planning and transactions but weak at what happens minute by minute on the floor. It knows a production order was released and later confirmed; it rarely knows which machine stopped, why, for how long, which operator ran it, which material lot went into which batch, or how the process parameters looked. That gap is filled by an MES at ISA 95 level 3, or by manual entry, which introduces delay and errors.
The most useful integration patterns move production orders and master data from ERP to the floor, and send confirmations, consumption, scrap, quality results and stock movements back, automatically and with an audit trail. Planning stays in the ERP; execution truth flows up from the machines.

- MRP and capacity planning
- ISA 95 level 4
- Weak at minute by minute shop floor execution
- MES fills the execution gap and confirms back to ERP
Questions
What is the difference between ERP and MES?
ERP plans and records the business: orders, materials, costs. MES executes and records production on the floor: machine states, operators, lots, quality, and confirms results back to ERP.
Can ERP replace an MES?
Rarely completely. Some ERPs have shop floor modules, but they usually lack machine connectivity, real time performance tracking and detailed genealogy. Many plants pair ERP with MES.
Is Tally an ERP?
Tally is primarily accounting and inventory software used widely in India. Manufacturers often extend it or integrate it with production and attendance systems rather than treating it as a full ERP.

How we help with ERP
We integrate shop floor data with SAP, Oracle, Dynamics, Tally and other ERPs through their standard interfaces, and build custom ERP modules where an off the shelf product does not fit the process.
