Short answer: Cyber Defence, a Hisar, Haryana software company led by full-stack developer Amit Kumar (CEH, CRTA), builds custom ERP software for businesses across India remotely. We unify inventory, accounting, HR, and operations into one secure, scalable system with flat written pricing and 100% code ownership.
What is an ERP and who needs custom ERP development?
An ERP (Enterprise Resource Planning) system is software that connects and manages the core departments of a business — inventory, purchasing, sales, accounting, HR, and production — inside one integrated platform. Instead of separate tools that do not talk to each other, an ERP gives you a single database where a sale automatically updates stock, accounting, and reports at the same time.
A typical ERP is built from modules such as:
- Inventory and warehouse — stock levels, batches, transfers, and reorder alerts
- Purchasing and vendors — purchase orders, supplier management, and GRN
- Sales and billing — quotations, invoices, and GST-compliant billing
- Accounting and finance — ledgers, payables, receivables, and financial reports
- HR and payroll — employees, attendance, leave, and salary processing
- Production and manufacturing — bills of materials, work orders, and job tracking
You need a custom ERP when your business has outgrown spreadsheets and disconnected apps, when generic ERP products are too rigid or too expensive per user, or when your processes (especially in manufacturing, distribution, and trading) are unique enough that off-the-shelf software cannot model them properly.

- Inventory, sales, purchase, and accounts modules — fully integrated in one database

- GST-compliant billing and reporting — tailored to Indian requirements
- Role-based access control — each department and role sees only what it should

- Security and audit trails — reviewed by a certified ethical hacker (CEH, CRTA)
- Training, deployment, and support
Off-the-shelf ERP vs custom ERP
Off-the-shelf ERPs (like large packaged suites) are proven and fast to deploy, but they are expensive, charge per user, and force your business to change its processes to fit the software. Custom ERP fits your exact workflows, includes only the modules you need, removes recurring per-seat licenses, and gives you full ownership. The tradeoff is a higher upfront cost and longer build time. For some businesses a configured off-the-shelf ERP is genuinely the right call, and we will tell you so honestly rather than push a custom build.

Honest ERP development pricing in India
| ERP scope | Indicative price (INR) | Typical timeline |
|---|---|---|
| Core ERP (inventory + sales + billing) | Rs 1,00,000+ | 8-12 weeks |
| ERP with accounts + HR + purchase | Rs 2,50,000+ | 12-20 weeks |
| Full manufacturing / multi-branch ERP | Rs 5,00,000+ | 20+ weeks |
| Supporting website / portal | Rs 8,000 - Rs 45,000 | 1-4 weeks |
A custom ERP starts at Rs 1,00,000+ and is always scoped after a free call, because the price depends on modules, users, branches, and integrations. We offer flat written pricing, EMI options, 100% code ownership, and security built in. No endless per-user licensing, because the ERP is yours.

What you get on handover
An ERP runs your whole business, so ownership and control are non-negotiable, and we deliver both. On completion you receive the full source code and repository, the database with your migrated master data, complete technical, admin, and user documentation, deployment and backup configuration, and all credentials. We train your accounts, stores, and HR teams so adoption is smooth, and we document the role-based permissions and audit trails your auditors will ask about. Because there are no per-user license fees, adding branches or staff never inflates a recurring bill. You can host the ERP on your own infrastructure, extend it with any developer, and keep your financial and operational data entirely in-house. Ongoing maintenance and new modules are available on your terms, never as a lock-in. For government tenders, our GeM registration and ISO certification make procurement straightforward.
Industries that benefit most from a custom ERP
ERP delivers the biggest returns wherever inventory, money, and people all move at once. We commonly build ERPs for:
- Manufacturing — bills of materials, work orders, and shop-floor tracking
- Trading and distribution — multi-warehouse stock, purchase, and GST billing
- Retail chains — multi-branch inventory, sales, and central reporting
- Pharma and FMCG — batch, expiry, and compliance-heavy inventory
- Construction and projects — material, labour, and project cost tracking
- Services and institutions — accounts, payroll, and resource planning
How an ERP saves time and reduces errors
The real value of an ERP is that data is entered once and flows everywhere. When a sale is recorded, stock reduces, the invoice is raised, the ledger updates, and the dashboard refreshes automatically, with no duplicate entry and no reconciliation between separate tools. This removes the errors that creep in when teams copy numbers between spreadsheets, and it gives management a single, trusted view of the business in real time. Reorder alerts prevent stockouts, GST reports are generated in minutes instead of days, and approvals move through defined workflows instead of email chains. Because access is role-based, staff see only what their job requires, which protects sensitive financial and HR data. Over time, the hours saved on manual reconciliation and the errors avoided usually justify the investment well beyond the initial build cost.

FAQ
How much does custom ERP development cost in India?
A core ERP (inventory, sales, billing) starts at Rs 1,00,000+, one with accounts, HR, and purchase from Rs 2,50,000+, and a full manufacturing or multi-branch ERP from Rs 5,00,000+. Every ERP is scoped after a free call.
Should I buy an off-the-shelf ERP or build a custom one?
Buy off-the-shelf if a packaged ERP fits your processes and budget. Build custom when your workflows are unique, per-user fees are high, or you need exact-fit modules and full ownership. We give honest advice based on your situation.
Can the ERP handle GST billing and Indian compliance?
Yes. We build GST-compliant invoicing and reporting, and can integrate with e-way bill and GST portals so your billing and filing stay compliant.
Can you migrate our existing inventory and accounts data?
Yes. We migrate master data such as items, stock, ledgers, and customers from your spreadsheets or existing software, with validation to prevent data loss.
Is our financial and HR data secure in a custom ERP?
Yes. We enforce role-based access control, encryption, secure authentication, and audit trails, with a security review by our certified ethical hacker (CEH, CRTA). Since you own the system, your sensitive data is not held by a third-party SaaS.
Can we start small and add modules later?
Yes. We build ERPs modularly, so you can launch core modules first and add accounts, HR, production, or multi-branch support as your business grows.
