India ERP GST Readiness Assessment for Manufacturers
GST problems in manufacturing rarely come from one big error. They come from many small manual steps between the ERP, the portal and the books. This assessment tests where those steps remain.
1. How clean is the HSN and GST rate data in your item master?
2. How are e-invoices (IRN) generated?
3. How are e-way bills generated?
4. How do you reconcile purchases with GSTR-2B?
5. How is reverse charge (RCM) handled?
6. How are ITC reversals tracked, such as unpaid vendors beyond 180 days and blocked credits?
7. How do you prepare GSTR-1 and GSTR-3B?
8. Can you trace any GST figure back to the underlying invoices and postings?
9. How are notices, mismatches and credit notes controlled?
10. How controlled is access and change in GST configuration (tax codes, rates, HSN)?
How to use the assessment
Have the finance controller and the ERP manager answer together, because each knows a different half of the process. Pick the option that matches what happens in a typical month, not what the policy says. The score gives a rough maturity band, and the recommendations list the highest value fixes for that band. Retake it after you make changes to see progress.
- Answer for a typical month, not the best month
- Include both finance and ERP people in the answers
- Retake it after each improvement
What the ten questions cover
The questions follow the GST data flow: item master and rates, e-invoice generation, e-way bills, purchase reconciliation with GSTR-2B, reverse charge, ITC reversals, return preparation, traceability, notice handling and access control over tax setup. Together they show whether data flows from transactions to returns with controls, or whether people patch gaps with spreadsheets.
Reading your result
Scores below 40 percent usually mean month end is a scramble and ITC leakage is likely. Between 40 and 64, the basics exist but reconciliation and exception handling are manual. Above 65, the likely work is audit trail and monitoring. The score is a conversation starter, not an audit opinion, and it does not replace advice from your GST professional.
Common mistakes
Teams buy a GST add-on without fixing item master data, which carries errors straight into returns. Others automate returns but never reconcile purchases, so ITC mismatches stay hidden until a notice. A third mistake is giving many users access to tax code setup without approvals, which makes wrong rates hard to trace.
Frequently Asked Questions
Is this assessment specific to one ERP?
No. The questions apply to SAP, Oracle, Infor, Tally, Busy, NetSuite and others. The answers differ by system, but the workflows, such as e-invoice, e-way bill and 2B reconciliation, are the same.
Does a high score mean we are audit ready?
Not by itself. It shows process maturity at a high level. Audit readiness also depends on correct tax treatment, documentation and your professional adviser's review of specific transactions.
Who should answer the questions?
Ideally the finance controller or GST head along with the ERP manager. Finance knows the return and notice process, while the ERP manager knows how invoices, e-way bills and tax codes are actually configured.
How often should we reassess?
Once or twice a year, and after any major ERP change, new plant, GST notification that affects your products or a change in turnover that brings new e-invoice or HSN obligations.
If your result shows gaps, we can help you design reports and checks that run on your own ERP data without sending it outside your environment.
