Why Manufacturers Need a Different Checklist
ERPNext implementation for a manufacturing company is fundamentally different from a trading or service business. You're dealing with Bills of Materials, production planning, quality inspection, subcontracting, and shop floor operations - areas where a generic ERP approach falls apart.
This checklist is built from our experience implementing ERPNext for manufacturers across GIDC industrial areas in Gujarat - from tile factories in Morbi to chemical plants in Ankleshwar to auto-part manufacturers in Sanand.
Phase 1 • Week 1-2
Process Study & Discovery
This is where your implementation partner visits your factory and documents how your business actually works - not how you think it works.
Map the complete production flow - from raw material receipt to finished goods dispatch. Document every stage.
Document all Bill of Materials (BOMs) - single-level and multi-level. Include sub-assemblies, raw materials, and consumables.
Identify manufacturing operations - list every operation (cutting, welding, assembly, packaging) with average time per operation.
Map inventory locations - raw material store, WIP area, finished goods warehouse, rejection area. Each needs a separate warehouse in ERPNext.
Document quality inspection points - incoming raw material QC, in-process QC, and final inspection parameters.
List subcontracting processes - which operations are outsourced? What raw materials go to the subcontractor?
Map approval hierarchies - who approves purchase orders, work orders, stock entries, and delivery notes?
Document current pain points - what's broken? Inventory mismatches? Delayed production? Manual tracking?
Phase 2 • Week 3-4
Accounting & Financial Setup
Always set up accounting first. This is the foundation everything else builds on.
Chart of Accounts - map from Tally/existing system. Include manufacturing-specific accounts: WIP, FG Stock, Scrap, Job Work charges.
Cost Centers - create cost centers per department: Production, Quality, Warehouse, Admin, Sales.
GST Configuration - set up GSTIN, e-Invoice, e-Way Bill, HSN codes for all items, TDS/TCS templates.
Tax templates - configure tax templates for intra-state, inter-state, exempt, zero-rated, and reverse charge transactions.
Payment terms - set up standard payment terms (Net 30, Net 60, advance + balance, etc.).
Bank accounts - add all bank accounts with proper GL mapping for auto-reconciliation.
Currency & exchange rates - if you export, configure multi-currency with rate sources.
Phase 3 • Week 5-8
Manufacturing Module Configuration
This is the core of your manufacturing ERP - get this right, and everything else flows smoothly.
Item Masters
Create item master hierarchy - Raw Materials, Sub-Assemblies, Finished Goods, Consumables, Packing Materials.
Set valuation methods - FIFO for most items. Moving Average for bulk raw materials. Be consistent.
Configure UoMs & conversions - purchase in KG but manufacture in pieces? Set up UoM conversion factors.
Batch & serial tracking - enable batch tracking for raw materials that need traceability (chemicals, pharma, food).
Bill of Materials (BOM)
Create all BOMs - start with simple single-level BOMs, then build multi-level for complex products.
Define operations - link each BOM to workstations and operations with standard times.
Set scrap percentages - define expected scrap/waste at each BOM level for accurate costing.
Configure BOM costing - ensure BOM costs roll up correctly including operation costs and overheads.
Production & Work Orders
Configure Workstations - define capacity, operating hours, and hourly rates per workstation.
Set up Work Order workflow - Draft → Submitted → In Process → Completed. Add approval steps if needed.
Configure Job Cards - enable if you track time per operation per work order.
Production Plan - test production planning from Sales Orders to Work Orders to Material Requests.
Quality & Inspection
Define Quality Inspection Templates - for incoming RM, in-process, and finished goods with acceptance criteria.
Link inspections to Stock Entries - mandatory QC before material can move to the next stage.
Rejection workflow - configure what happens to rejected materials (return to supplier, rework, scrap).
Subcontracting
Set up subcontracting BOMs - define which items are sent to subcontractors and what comes back.
Configure Stock Entry for RM transfer - track raw materials sent to subcontractors.
Reconciliation process - ensure RM consumed by subcontractor matches what was sent.
Phase 4 • Week 9-10
Data Migration
Item master import - all items with HSN codes, UoMs, pricing, and warehouse defaults.
Customer & Supplier masters - with GSTIN, addresses, payment terms, and credit limits.
Opening stock - warehouse-wise inventory with valuation as of cutoff date.
Opening balances - accounts receivable, accounts payable, and bank balances from Tally/Excel.
Outstanding invoices - pending customer invoices and supplier bills with aging.
Reconciliation check - Trial Balance in ERPNext must match Tally/previous system exactly.
Phase 5 • Week 11-12
Training & Go-Live
Accountant training - invoicing, payments, bank reconciliation, GST returns, P&L review.
Warehouse/store keeper training - stock entries, material requests, stock reconciliation, batch tracking.
Production team training - work orders, job cards, stock entry for manufacture, QC inspections.
Purchase team training - supplier quotations, purchase orders, GRN process, purchase invoicing.
Management dashboards - train owners/managers on reports, dashboards, and approval workflows.
Parallel run (optional) - run both old system and ERPNext for 1-2 weeks to verify accuracy.
Go-Live ✅ - cut over to ERPNext as the primary system. Old system becomes read-only.
Typical Manufacturing Implementation Timeline
| Phase |
Duration |
Key Deliverables |
| Process Study | 1-2 weeks | Process document, BOM list, gap analysis |
| Accounting Setup | 1-2 weeks | CoA, GST, tax templates, cost centers |
| Manufacturing Config | 3-4 weeks | BOMs, workstations, work orders, QC, subcontracting |
| Data Migration | 2-3 weeks | Item masters, opening stock, balances, reconciliation |
| Training & Go-Live | 2-3 weeks | Role-based training, SOPs, go-live support |
| + 30 days post-go-live stabilization |
Final Thoughts
Manufacturing ERP implementation is complex, but it doesn't have to be chaotic. With a structured checklist and an experienced partner who understands factory floor operations, you can go live confidently in 10-14 weeks.
The key is discipline: accounting first, configuration before customization, and thorough data validation before go-live. Skip any of these and you'll pay for it later.
