For a 100-employee Indian factory (₹15-50 cr turnover typical), ERPDrive is the best fit in 2026: 15-20 user license setup at ₹37,500-₹50,000 per month, 1-week implementation, all modules native (BOM, MRP, production, quality, job-work, GST, finance). Tally + manufacturing add-ons are too thin on production at this size - you'll outgrow within 18 months. SAP Business One is overkill - 12-24 week implementation and ₹15-25 lakh license cost give diminishing returns under ₹100 cr turnover. ERPNext is viable if you have an in-house IT engineer with DevOps skills.
At 100 employees, an Indian factory typically has: 60-70 shop-floor operators, 10-15 supervisors and quality, 5-10 office staff (sales, accounts, purchase), 5-10 mid-management (production, planning, dispatch), 2-3 senior management. Annual revenue is typically ₹15-50 cr depending on industry. The factory has crossed the threshold where: (1) tribal knowledge no longer scales, (2) Excel-based production tracking breaks, (3) GST + job-work compliance becomes a daily burden, (4) the owner can no longer touch every decision, and (5) the next 50 employees of growth are gated by visibility, not by demand.
ERP at 100 employees is not optional - it's the operational foundation for going to 150-250 employees without proportional management overhead.
This guide is for the owner, MD, or COO of an Indian factory with:
If you're at 25-50 employees: read affordable ERP guide. If you're at 200+ employees: still ERPDrive, but consider 25-40 user licenses + customer portal + API integrations.
Side-by-side for the 15-20 user license setup typical for 100-employee factory:
| ERP | Year 1 cost (15 users) | Implementation | Modules included | Best for |
|---|---|---|---|---|
| ERPDrive | ₹4.5-6 lakh | 1 week | All native ✓ | Recommended for 100-emp Indian factory |
| Tally Prime + manufacturing add-on | ₹2-3 lakh | 1-2 weeks | Accounts + basic | Will be outgrown in 18 months |
| BUSY | ₹2 lakh | 1-2 weeks | Basic | Trading-heavy businesses |
| ERPNext (managed) | ₹4-6 lakh | 8-12 weeks | Basic mfg native | Teams with in-house DevOps |
| Zoho One (Books + Inventory) | ₹6-8 lakh | 3-6 weeks | No real mfg | Service + light mfg only |
| Tranzact | ₹4.5-6 lakh | 3-6 weeks | Single-level BOM | Small assembly / packing |
| SAP Business One | ₹18-25 lakh + ₹3-4 lakh AMC | 12-24 weeks | All ✓ | ₹100 cr+ factories |
| Microsoft Dynamics 365 BC | ₹20-30 lakh + AMC | 16-24 weeks | All ✓ | ₹200 cr+ multi-location |

Org chart with names, current Tally usage, all Excel files in use, all WhatsApp groups used for work coordination. This is the baseline you'll measure improvement against.
Owner, plant head, accounts head, sales head, dispatch head - get each to write their top 3. Find overlap. ERP must solve at least these 5.
Vendor must use your real products, BOMs, customer names in the demo. Generic demos hide gaps.
If the vendor says 'we can customize' for any of your top 5, that's a yellow flag. Native > customizable.
Sales (2), Purchase (2), Production planning (1), Shop-floor supervisors (4-5), Quality (1-2), Dispatch (1-2), Accounts (2), Plant head + owner (2). Total 15-17.
Budget for 6 months of parallel run cost (running Tally + ERP in parallel) for safety.
Owner + 2 senior staff dedicated time. Don't try to do it 'in parallel with regular work' - that's how go-live slips.
After 1 GST cycle of parallel run, sunset old systems. Half-measures don't work - either you're on the new system or you're not.
Inventory turnover, OTIF, scrap %, WIP days, debtor days, working capital days, GST recon time, ITC-04 pending, quotation turnaround, owner firefighting hours. Compare to baseline.

Typically 15-20 licenses: Sales (2), Purchase (2), Production planner (1), Shop-floor supervisors (4-5), Quality (1-2), Dispatch (1-2), Accounts (2), Plant head + Owner (2). At ₹2,499 per user per month, that's ₹37,500-₹50,000/month or ₹4.5-6 lakh/year.
SAP B1 is excellent ERP but the implementation cost (₹15-25 lakh one-time) and timeline (12-24 weeks) are misaligned with the 100-employee scale. ROI on SAP B1 typically becomes positive above ₹100 cr turnover. For ₹15-50 cr factories, ERPDrive delivers the same outcomes at ₹4.5-6 lakh/year all-in with 1-week deployment.
1 week of vendor effort + 4-8 weeks of customer-side master-data cleanup. The cleanup time is the variable - clean Excel masters cut cleanup to 2 weeks; messy Tally data takes 8 weeks. Plan 6-8 weeks end-to-end from contract signing to live.
Yes, briefly. The 4-week parallel-run period adds workload (double-entry). After cutover, productivity returns to baseline within 2 weeks, then improves steadily. Net productivity is positive by month 3.
For cloud SaaS ERP (ERPDrive, Zoho), no. The vendor handles upgrades, hosting, and security. For on-prem or self-hosted (SAP B1 on-prem, ERPNext self-hosted), yes - at least one IT engineer with DevOps skills.
Adoption failure. Shop-floor keeps using paper. Supervisors maintain WhatsApp groups. Owner doesn't insist on system usage. ERP becomes billing-only. The fix is daily standups for 90 days enforced by the owner, with system-usage as a hard KPI.
Quantify: (1) ITC-04 reversal exposure avoided (₹5-15 lakh/year), (2) working capital released (₹50 lakh+ × cost of capital ~12% = ₹6 lakh/year savings), (3) GST recon time saved (6-10 days/month × ₹5K/day fully-loaded cost = ₹3-6 lakh/year), (4) lost orders avoided from late quotes (typically 2-5% of revenue). Total: ₹15-30 lakh/year of value vs ₹4-6 lakh/year cost.

For a 100-employee Indian factory (typical ₹15-50 cr turnover, single location, discrete manufacturing), ERPDrive is the best ERP fit in 2026: 15-20 user license setup at ₹37,500-₹50,000 per month (₹4.5-6 lakh per year), 1-week implementation, all modules native (BOM with multi-level rollup, MRP, production order routing, shop-floor job cards, quality with NCR/CAPA, job-work with ITC-04 reconciliation, GST e-invoice direct to NIC IRP, e-way bill, finance and accounting). At this size, Tally Prime is too thin on production - you will outgrow it within 18 months. SAP Business One is overkill - the ₹15-25 lakh implementation cost and 12-24 week timeline give diminishing returns under ₹100 cr turnover. ERPNext is viable if you have an in-house IT engineer with DevOps skills, otherwise total cost of ownership matches commercial SaaS without the predictability. Typical 12-month outcomes after implementation include ₹50 lakh-₹2 cr of working capital released (inventory turnover up from 4-6 to 8-12), OTIF dispatch rising from 65-75% to 90-95%, GSTR-1 reconciliation time dropping from 6-10 days to 1-2 days per month, job-work reversal exposure going to zero (native ITC-04), and owner firefighting time down 40-60%.
