Most mid-size Indian businesses grow into a tangle of disconnected tools — Tally for accounts, Excel for inventory, a separate HR software for payroll and WhatsApp for purchase orders. Data never lines up, staff duplicate entries, and the owner still cannot see a real-time picture of the company. A custom ERP system solves this by connecting every department into one database with role-based access, automated workflows and dashboards that show the full business health at a glance. At Chulbul Design, we build custom ERP systems for manufacturing companies, trading firms, construction businesses, logistics companies and multi-branch service organisations. We also implement and customise Odoo, ERPNext and Zoho ERP when a fully custom build is not required.
GST-Compliant Billing, Inventory & Accounts — Fully Linked
The core of any Indian ERP is getting billing, stock and accounts to talk to each other without manual re-entry. Our ERP modules are built to Indian compliance standards from the ground up: GST invoicing (B2B/B2C/export), e-way bill generation, GSTR-1/3B data export, TDS and TCS tracking, and reconciliation with GSTN portal data. When a sales order is confirmed, the stock is reserved automatically. When the invoice is raised, the journal entry posts without a human touch. When payment arrives, the ledger updates and outstanding reports reflect reality in seconds — not at month end when the accountant finally reconciles.
A Delhi-based trading firm: eliminated 3 manual data-entry roles and cut month-end closing from 8 days to same day after ERP deployment.
- GST invoicing — B2B, B2C, export, debit/credit notes
- Auto e-way bill via NIC API integration
- Real-time stock across multiple warehouses or branches
- Accounts payable/receivable with aging reports
- P&L, balance sheet and cash-flow dashboard for owners
Manufacturing & Procurement Modules Built for Indian Operations
For manufacturing companies, a generic ERP is rarely enough. Indian manufacturers deal with BOM (bill of materials) variations per customer, job work sub-contracting under GST, quality inspection at goods receipt, and machine-level production planning tied to order deadlines. Our manufacturing ERP module covers production orders, work-in-progress tracking, finished goods valuation (FIFO/weighted average), scrap management and shift-wise output reports. The procurement module handles multi-level purchase approvals, vendor rate comparisons, pending PO tracking and three-way matching between PO, GRN and invoice before a payment is approved.
A Ludhiana garment manufacturer: reduced raw material overstock by 34% and late deliveries by 60% within 4 months of ERP go-live.
- Bill of materials with multi-level sub-assemblies
- Job work in/out with GST 2B reconciliation
- Multi-level purchase approval workflow
- Vendor scorecards — delivery, quality, price history
- Reorder-level alerts with auto draft PO generation
HR, Payroll & Attendance — India Statutory Compliant
Indian payroll is complex: PF (EPF/VPF), ESI, professional tax (varies by state), LWF, TDS on salary under new/old regime, and Form 16 generation at year end. Our HR module handles all of this automatically. Attendance is captured via biometric integration, mobile app geo-punch or manual entry. Leaves are tracked against Indian leave types (CL, EL, SL, national holidays per state). Payroll is calculated with a single click, salary slips are sent to employees via email/WhatsApp, and PF/ESI challans are generated ready for upload on the government portals. For construction companies and labour contractors, we build daily wage and piece-rate payroll with site-wise cost allocation.
- Auto EPF/ESI/PT calculation and challan generation
- Biometric / mobile attendance integration
- One-click payroll with salary slip on WhatsApp
- TDS on salary — old and new regime comparison
- Form 16 / Form 12BA auto-generation

Our ERP Development Process
Business Audit
We map every department's current workflow, data sources, pain points and reporting needs before writing a single line of code.
Module Blueprint
We define the modules, user roles, approval workflows, integrations and data migration plan in a detailed SRS document you approve before development starts.
Phased Development
Modules are built in priority order — core billing and inventory first, then manufacturing, HR and analytics. Each phase is demoed before the next begins.
Data Migration & Training
Historic data is migrated from Tally, Excel or your current software. Role-specific training is delivered to each department before go-live.
Go-Live & Support
We run parallel operations for 2 weeks to catch any discrepancies, then fully switch over. Ongoing support covers bug fixes, compliance updates and feature additions.
