What drives custom ERP development cost?
Five factors determine the cost of building a custom ERP in India:
- Number of modules: Each module (finance, inventory, HRMS, CRM, manufacturing, etc.) adds 3–8 weeks of development. A basic 3-module ERP costs 3–4x less than a 12-module full-feature ERP.
- Number of locations: Multi-branch or multi-company ERP requires a more complex data architecture — role-based access, inter-branch transactions, and consolidated reporting add 30–50% to scope.
- Integrations: Third-party integrations — GST/e-invoice, payment gateways, banking APIs, WhatsApp Business API, biometric devices — add ₹50,000–₹3,00,000 each depending on complexity.
- Custom workflows: A standard purchase approval workflow is quick to build. A custom multi-level approval workflow with escalation rules, alternate approvers, and mobile approval takes 3–5x longer.
- AI layer: Adding AI automation — document processing, WhatsApp bots, AI copilot, voice agents — adds ₹5–25L to the base ERP cost depending on the number of agents.
ERP cost by industry type
Manufacturing ERP cost
Manufacturing ERP is one of the more complex builds — BOM, production orders, quality control, multi-stage WIP tracking, and job costing require significant architecture. A typical manufacturing ERP for a company with ₹50–200Cr turnover costs:
| Scope | Modules included | Timeline | Cost |
|---|---|---|---|
| Discrete manufacturing (basic) | Purchase, inventory, production, sales, GST billing | 12–16 weeks | ₹8–15L |
| Process manufacturing | Above + BOM, job costing, QC, batch tracking, multi-plant | 18–28 weeks | ₹18–35L |
| Enterprise manufacturing | Above + MES integration, AI layer, BI dashboard | 6–10 months | ₹40–80L |
School ERP development cost
School ERP cost depends on the number of campuses, students, and modules. A single-campus school ERP with parent app and WhatsApp is significantly cheaper than a multi-campus school group ERP with AI agents:
| Scope | Modules | Cost |
|---|---|---|
| Single campus (1,000–5,000 students) | Admissions, fee, academic, attendance, parent app | ₹5–10L |
| School group (3–10 campuses) | Above + multi-campus dashboard, consolidated finance | ₹12–25L |
| Education trust (10+ campuses) | Above + AI agents (admission, fee recovery), BI | ₹30–60L |
Hospital ERP / HMS development cost
Hospital management system cost varies significantly — a basic clinic ERP is very different from a multi-specialty hospital ERP with NABH compliance, TPA billing, and lab integration:
| Scope | Cost |
|---|---|
| Clinic / nursing home (OPD + pharmacy + billing) | ₹5–10L |
| Mid-size hospital (OPD + IPD + lab + insurance) | ₹15–35L |
| Hospital group (multi-branch + NABH + AI) | ₹40–80L+ |
Trading and distribution ERP cost
Trading ERP for a distributor replacing Tally and Excel typically costs ₹6–25L depending on the complexity of the product catalogue, number of godowns, credit customer volume, and whether van sales or CRM is included.
Hidden costs to watch out for
⚠️ Beware of underquoted ERP projects. A vendor quoting ₹2L for a "full ERP" is either building something extremely basic, planning to add scope and charge more, or cutting corners on quality. ERP development is fundamentally a complex, long-horizon project — realistic pricing starts at ₹3L and rises steeply with scope.
- Data migration: Migrating from Tally, legacy software, or Excel takes 2–6 weeks and typically adds ₹1–5L to the project. Don't overlook this.
- Training: Budget for department-by-department training — a 100-user ERP rollout needs at minimum 3–5 days of training time across departments.
- Post-go-live support: The first 3 months after go-live always need changes — edge cases your team didn't think of during requirements. Ensure support is included in the contract.
- Infrastructure: Cloud hosting (AWS/Azure), SMS and WhatsApp API costs, and domain/SSL are not typically included in ERP build cost. Budget ₹3,000–15,000/month depending on usage.
Custom ERP vs. SAP vs. Odoo — which costs more over 5 years?
| Option | Year 1 cost | Annual recurring | 5-year total (50 users) |
|---|---|---|---|
| SAP Business One | ₹40–80L implementation | ₹10–20L licensing + support | ₹90L–₹1.8Cr |
| Odoo Enterprise | ₹8–20L implementation | ₹4–10L/year (per user) | ₹28–70L |
| XPndAI Custom ERP | ₹8–50L (one-time) | ₹1–3L/year (hosting only) | ₹13–65L |
Key insight: Custom ERP has higher upfront cost than basic Odoo, but zero annual licensing. Over 5 years, the total cost of ownership is almost always lower — especially as your user count grows.
How to get an accurate ERP cost estimate
The only way to get an accurate custom ERP cost is a proper discovery workshop — where the developer maps your exact workflow, documents every module and integration, and prices based on actual scope. A quote given without a discovery workshop is a guess.
XPndAI offers a free discovery workshop — 3–5 days with your operations team — and delivers a fixed-price proposal based on actual documented scope. No scope creep. No surprise invoices.
