Walk into most manufacturing units in India and the 'ERP' is three things: Tally for accounts, a thick Excel file for stock, and a WhatsApp group for orders. It holds — until raw material discrepancies, job work tracking and customer-wise delivery promises start quietly eating your margin.
The modules a manufacturing unit actually needs
Forget the 40-module catalogue software vendors love. A working manufacturing ERP in India needs six things done properly:
- Raw material & finished goods inventory — with batch/lot tracking and stock ageing, because idle material is money parked in the store.
- Job work (contract manufacturing) — send-to, receive-from, and payment per piece or per weight. If you do job work, this module alone decides whether the ERP earns its keep.
- Production tracking — order → work order → stage-wise status, so "where is this order?" stops being a phone call to the floor.
- Quality checks — at raw material receipt and before dispatch, with rejection reasons captured.
- Sales with GST billing — customer-wise rates, credit limits, e-invoice ready, and GST-compliant invoicing that reconciles with your returns.
- Tally integration — your accounts team lives in Tally. The ERP should push vouchers cleanly, not replace the habit overnight.
Ready-made vs custom: the honest comparison
- Ready-made wins on speed and sticker price. It also wins on friction — you adapt your process to their screens, and every deviation is a consultant-billed customisation.
- Custom wins on fit. Your unit's stages, units of measure, and reports are exactly what you asked for, the screens stay simple enough that the floor staff actually use them, and you own the roadmap — future modules cost you a sprint, not a license renewal.
- The real decision rule: how many of the six modules above does the off-the-shelf product cover 80%+ of your way? If it's three, the "savings" disappear in the first year of workarounds.
Why "Tally + custom ERP" is the Indian pattern
Most of our manufacturing clients don't throw Tally out — they put a custom ERP around it. Tally stays the system of record for accounts; the ERP handles operations (stock, production, job work, dispatch). Vouchers flow between them automatically, and nobody's daily habit changes. You can see the full approach on our custom ERP services page.
Realistic timelines and cost
A core system — inventory, billing, job work and basic production — typically goes live in 8–12 weeks, and you use value from week one, not after a "big bang" cutover. Data migration (from Tally, Excel, or legacy software) is done with field-level mapping and a parallel month. Cost is quote-based on the module list; the point of this guide is that the module list should be yours, not the vendor's default.
Red flags when evaluating ERP vendors
- They demo a product, not your process — ask them to demo your job-work flow, not theirs.
- Quoting per-user licences that punish your growth.
- "Yes" to every request with no module map or timeline.
- No plan for Tally integration — because they expect you to abandon it.
Once the ERP is running, the boring work begins — servers, backups, updates — which is exactly what our AMC plans exist for.
Key takeaways
- Fit beats features: count how many of your six must-have modules the off-the-shelf product truly covers.
- Tally + custom ERP is the pragmatic Indian pattern — don't force a full accounting replacement.
- A core manufacturing ERP goes live in 8–12 weeks, with value from week one.
- Make the vendor demo YOUR job-work flow, not their standard product.
- Parallel-run month + field-level data migration = a cutover nobody fears.
