What is Included in the Discrete Manufacturing Suite

Built specifically for job shops and serial component manufacturers navigating multi-stage routings, subcontracting challans, and machine bottlenecks.

Multi-Operation Routing (BoO)

Step-by-Step Machine Operations (BoO): Plan and track every stage in sequence: from raw cutting, lathe turning, CNC milling, precision grinding, to final digital dimension checks (CMM).

Subcontracting Challans

100% Subcontractor Tax Compliance (ITC-04): Track raw materials sent to outside job-workers and ensure full tax matching when finished goods return.

Live Spindle OEE Telemetry

Real-time tracking of machine runtimes, setup idle hours, feed rate overrides, and micro-stoppages via IoT gateways.

Scrap & Rejection Notes

Detailed defect root-cause coding, scrap recovery weight valuation, and automated rejection debit notes to raw casting suppliers.

Tooling & Fixture Vault

Lifecycle tracking for cutting tool inserts, milling cutters, and custom fixtures with automated insert reorder triggers.

Standard vs Actual Costing

True job-order absorption costing factoring actual machine hour rates, tooling wear, power consumption, and operator wages.

Frequently Asked Questions

Concrete answers to technical and operational questions asked by plant directors and CFOs.

Every batch dispatched to external vendors (for heat treatment, electroplating, or blackening) is tracked on an automated Annexure IV delivery challan. When goods return, incoming QC registers good pieces, vendor scrap, and lost parts. The system automatically issues supplier debit notes for unaccounted shortages, completely stopping inventory leakages.

Yes. Our edge IoT gateway boxes connect to current transducers (CT clamps) and cycle limit switches on older manual or semi-automatic machines, measuring spindle load and cycle counts without altering machine electricals.

Our import bridge accepts multi-level assembly structures directly from SolidWorks, AutoCAD, and Excel, mapping raw materials, sub-assemblies, fasteners, and standard bought-out parts with full revision locking.

Yes. GST e-Invoices and e-Way bills are generated automatically with QR codes directly from within the dispatch module, eliminating double data entry on government portals.
