The six phases
Each phase ends in something working rather than in a document. A phase that produces only a report is a phase the business cannot judge.
Step 1: Process mapping
Each function at your Indore operation walked end to end as it actually runs, with a named process owner recorded for every one.
2 to 3 weeksStep 2: Master data cleansing
Items, customers, suppliers, accounts, tax codes and units de-duplicated and standardised, then signed off by the owner of each set.
2 to 4 weeksStep 3: Configuration
Modules configured against the mapped process, with the Indian tax detail tested on real documents rather than samples.
3 to 5 weeksStep 4: Integration
Bank feeds, e-invoicing, e-way bills, CRM, website and any machine data, so nothing survives as a hand-maintained spreadsheet.
1 to 3 weeksStep 5: Training and parallel run
Training by role, then a parallel period where the old process still exists so the new one can be compared against it.
2 to 4 weeksStep 6: Phased go-live and hypercare
Finance and inventory first, then trade, then operations, with 30 days of hypercare following each cutover.
30 days per phase
04 Statutory
What Indian law expects of the system
An ERP holding a company's books is where the statutory record lives. Four requirements are configured rather than assumed.
| Requirement | Source | In configuration |
|---|---|---|
| Audit trail and edit log | Proviso to Rule 3(1), Companies (Accounts) Rules, 2014, from 1 April 2023 | Every transaction and change logged with its date, not capable of being disabled |
| Books on accrual, double entry | Section 128(1), Companies Act, 2013 | The ledger, not a spreadsheet, is the book of account |
| Eight year retention | Section 128(5), Companies Act, 2013 | The legacy system stays readable after migration |
| E-invoicing above ₹5 crore | GST e-invoicing mandate | The ERP reports each document to the Invoice Registration Portal, within 30 days at ₹10 crore and above |
- The Ministry of Corporate Affairs administers the audit trail and retention requirements, and a statutory auditor reports on whether the feature was in use through the year.
- The e-invoice portal is where the ERP registers each document and receives the Invoice Reference Number.
We underestimated our own item master. Cleaning it took three weeks and it is the only reason the stock reports are believable now.
05 Reference
Terms used in this plan
- Master data
- The stable reference data every transaction points at: items, customers, suppliers, accounts, tax codes, units of measure and warehouses.
- Cutover
- The point at which a process stops running in the old system and starts in the new one, with opening balances and open items carried across.
- Parallel run
- A period where old and new run side by side so results can be compared before the old process is retired.
- Hypercare
- The intensive support window immediately after a cutover, when usage questions arrive at their highest rate.
- Bill of materials
- Written BOM: the structured list of components and quantities consumed to make one unit of a finished good.
- Invoice Reference Number
- Written IRN: the identifier returned by the Invoice Registration Portal when an e-invoice is reported successfully.
- Data Protection Board of India
- The adjudicating body under the Digital Personal Data Protection Act, 2023. The Schedule to that Act sets fixed rupee ceilings rather than a share of turnover: up to ₹250 crore for failing to take reasonable security safeguards against a personal data breach, up to ₹200 crore for failing to notify the Board and the people affected, and up to ₹50 crore for a breach of any other provision. That is why consent, retention and access control are build decisions here rather than paperwork.
