BOM accuracy, job-work GST, and a quality-hold that actually holds.

Manufacturing leaks margin in three quiet places: BOMs that drift, scrap that doesn’t flow back to job cost, and job-work invoices that confuse the GST officer. We instrument all three.

Process from RM to FG, with operations. Perfection at BOM, QC and job-work entry. Productivity: scrap visible, on-time delivery rises, ITC stops leaking.

Today’s reality

Five frictions on the shop floor.

BOM drift

BOM was right at design. Then engineering changed three components, the storeman started substituting the unavailable bracket with another, and nobody updated the master. Costing is now wrong by 3–6%.

Scrap & rejection invisible

Rejected lots get adjusted into stock as “process loss”. Real scrap cost never reaches the job card. Margin per item is decorative.

Job-work GST confusion

Material out on Challan ITC-04, returned partially, billed as job work or sent back — the chain breaks somewhere. ITC sits at risk every quarter.

Quality hold leaks

QC says hold. Dispatch ships anyway because customer is screaming. Two weeks later, return and credit-note. Hold needs to be a system rule, not a sticker.

Capacity invisible

Sales commits delivery. Production discovers next week the line is double-booked. Customer-facing ETA is theatre.

Sub-contractor settlement

Job worker raises bill in Excel. Material accounting and labour rate reconcile on a different spreadsheet. Settlement runs 30–60 days behind.

Where productivity leaks

ERP enforces. CRM remembers. Helpdesk closes.

ERPOperational core

BOM, work order, QC, job work.

Frappe ERPNext — BOM with versioning, work-order with operations, QC at receipt and FG, job-work challan ITC-04, capacity planning at machine and shift level.

CRMCustomer memory

B2B quote, sample, dealer scheme.

Quote-to-order pipeline, sample dispatch tracking, dealer / distributor scheme management, secondary-sales capture, lead nurture by industry segment.

HelpdeskClosure layer

Warranty, RMA, defect.

Warranty claim with batch lookup, RMA workflow with replace / repair / refund, defect routing to QC and engineering, root-cause register.

What we configure

Eight modules. One per friction.

BOM versioning

  • Multi-level BOM with sub-assemblies
  • Engineering change order workflow with impact list
  • Substitute item table with cost differential
  • BOM cost recompute on price-list update

Work order & operations

  • Operation-wise routing with machine and time
  • Job card per operator, time and pieces
  • WIP visibility by operation
  • Real-time costing roll-up

Quality control

  • Inspection at receipt, in-process, FG
  • Hold / release with sampling rules
  • Non-conformance workflow with root-cause
  • CAPA register tied to defect type

Job work & ITC-04

  • Material out on Job Work Challan
  • Quarterly ITC-04 return generation
  • Return / settlement reconciliation
  • Sub-contractor rate master with GST

Batch & serial traceability

  • Batch on RM — lineage to FG dispatch
  • Serial / heat / lot tracking by item class
  • Customer-side recall report
  • Shelf-life and FEFO where relevant

Capacity planning

  • Machine + operator + shift calendar
  • Order promise with available-to-promise
  • Bottleneck flag with re-sequence suggestion
  • Production plan to MRP linkage

Cost & scrap

  • Standard vs actual cost per WO
  • Scrap account by item / line / shift
  • Yield variance report
  • Margin by SKU after scrap and rework

GST & statutory

  • E-invoice + e-way bill
  • GSTR-1, 3B, ITC-04, GSTR-2A reconciliation
  • TDS on contractor / job-worker payments
  • PF / ESI export from attendance
Outcome

What changes after we go live.

90days · first wins
  • BOM master locked, ECO workflow live
  • QC hold blocks FG — no override without reason
  • Job-work challan + ITC-04 generated cleanly
  • Operation-wise WIP visible from one screen
  • On-time delivery measured, not estimated
180days · margin clarifies
  • Margin per SKU is true — scrap and rework included
  • Yield variance investigated weekly, not yearly
  • Capacity-driven order promise replaces guesswork
  • Job-worker settlement runs to a 7-day cycle
  • Warranty + RMA closes inside 14 days
