Before You Start
ERP implementation is a business transformation project, not just a software installation. 60–70% of ERP projects fail — not because of bad software, but because of poor planning, inadequate training, and the wrong implementation partner. This guide helps you avoid those mistakes.
The 6 Phases of ERP Implementation
Discovery & Scoping
1–2 weeks- ✓Document your current business processes (purchase, sales, inventory, accounts)
- ✓Identify pain points and must-have requirements
- ✓Define ERP modules needed (which departments, which workflows)
- ✓Shortlist 2–3 ERP products and implementation partners
- ✓Get detailed implementation quotes with scope clearly defined
System Configuration
2–4 weeks- ✓Set up company, branches, departments, warehouses
- ✓Configure chart of accounts aligned to Indian accounting standards
- ✓Set up GST tax templates (CGST, SGST, IGST) and e-invoicing credentials
- ✓Configure item groups, item codes, units of measure
- ✓Set up customer and supplier groups, payment terms, price lists
- ✓Configure workflows, approval rules, and user roles
Data Migration
1–3 weeks- ✓Export and clean master data from Tally/Excel (customers, suppliers, items)
- ✓Validate and fix data quality issues before import
- ✓Import master data into ERP system
- ✓Enter opening stock with correct valuation (moving average or FIFO)
- ✓Enter opening account balances (Trial Balance cutoff date)
- ✓Reconcile migrated data with source system
User Training
1–2 weeks- ✓Role-based training: accounts team, purchase team, sales team, warehouse
- ✓Process walkthroughs: creating PO, goods receipt, sales invoice, payment
- ✓GST invoice generation, e-way bill, e-invoicing practice
- ✓Payroll processing (PF, ESIC, TDS deduction)
- ✓Report generation: P&L, stock summary, outstanding receivables
- ✓Admin training: user management, backup, configuration changes
Parallel Run / UAT
1–2 weeks- ✓Enter 1–2 weeks of live transactions in ERP alongside existing system
- ✓Compare ERP reports with existing system (stock, accounts)
- ✓Fix any configuration gaps found during parallel run
- ✓Get team sign-off that the system works as expected
- ✓Finalise go-live date and communicate to all departments
Go-Live & Hypercare
2–4 weeks- ✓Cutover: enter opening balances as of go-live date
- ✓All transactions now in ERP — old system retired
- ✓Daily check-ins with team to resolve questions
- ✓Monitor for data entry errors and correct them quickly
- ✓Partner support on-call for first 4 weeks post-live
- ✓Monthly review at 30 and 60 days post-live
ERP Implementation Timeline for Indian Businesses
| Company Size | Modules | ERPNext | SAP B1 |
|---|---|---|---|
| Small (5–20 users) | 3–5 modules | 4–8 weeks | 6–9 months |
| Mid (20–100 users) | 6–10 modules | 8–16 weeks | 9–15 months |
| Large (100+ users) | Full suite + mfg | 16–24 weeks | 12–18 months |
6 Common ERP Implementation Mistakes (and How to Avoid Them)
One person from your business must own the ERP project. Without a decision-maker accountable for outcomes, projects drift and deadlines slip.
Cleaning data after it's in the ERP is 10x harder. Deduplicate customers/suppliers, fix item codes, and verify opening balances before migration.
The #1 reason ERPs fail post-live: teams don't know how to use them. Budget 20–30% of the project for proper, hands-on training.
Define the Phase 1 scope tightly. Defer non-critical customisations to Phase 2. Every addition mid-project delays go-live and increases cost.
The cheapest implementation partner often costs the most in the long run — via rework, delays, and data loss. Evaluate case studies and references.
Who handles system issues after go-live? Establish a support SLA with your partner before signing — at minimum, a 3-month hypercare period.

Frequently Asked Questions
How long does ERP implementation take in India?
ERP implementation timeline in India depends on company size and the system chosen. ERPNext for a small business (10–30 users, 3–5 modules) typically takes 4–8 weeks. A mid-size company (30–100 users, 6–10 modules including manufacturing) takes 8–16 weeks. SAP Business One takes 6–18 months. Infonoxe Technologies typically completes ERPNext implementations in 6–10 weeks for trading and manufacturing companies in Pune.
What are the most common ERP implementation failures in India?
The most common ERP implementation failures in India are: (1) No internal "champion" or owner driving the project from the business side; (2) Poor data quality — migrating dirty or incomplete data from old systems; (3) Inadequate user training — buying expensive software but not investing in getting teams to use it; (4) Underestimating scope — hidden customisations required post-live; (5) Choosing the wrong implementation partner — companies that just install software but do not understand your business processes.
How much does ERP implementation cost in India?
ERP implementation cost in India: ERPNext for small businesses starts at ₹50,000–₹1,50,000 (3–5 modules, up to 15 users). Mid-size companies pay ₹1,50,000–₹5,00,000 (full suite, manufacturing, multi-location). Large companies pay ₹5,00,000–₹20,00,000+. SAP implementation costs ₹5L–₹50L+ excluding licensing. These costs include requirement analysis, configuration, data migration, training, and 3-month post-live support.
Do we need to shut down operations during ERP go-live?
No. A well-managed ERP go-live does not require shutting down operations. Infonoxe Technologies follows a parallel-run approach — your old system runs alongside the new ERP for 2–4 weeks during the go-live period. Transactions are entered in both systems until the team is confident, then the old system is retired. The most common go-live approach is a weekend cutover for the accounting/inventory cutoff.
What data needs to be migrated when implementing ERP?
Typical data migration for Indian businesses switching to ERP includes: customer and supplier master data, item/product catalogue with pricing, opening account balances from Tally or Excel, outstanding invoices and bills, inventory opening stock with valuation, employee records and payroll history, and fixed asset register. Infonoxe Technologies provides a detailed data migration template and validates all migrated data before go-live.
