About MAS Solar Systems
MAS Solar Systems is a solar panel manufacturer headquartered in South India, supplying photovoltaic modules and complete solar energy systems to commercial and industrial clients across the country.
With over 100 employees and ₹200 Cr+ in annual revenue, the company had grown rapidly - but its operational backbone had not kept pace. Procurement, production, finance, and HR were managed in silos, making real-time decision-making nearly impossible.
Scaling Pains Across Five Departments
Procurement, manufacturing, and finance ran on disconnected spreadsheets and legacy tools, creating data silos across departments.
No real-time visibility into raw material stock levels, leading to production stoppages and emergency purchases.
Month-end finance close took over two weeks due to manual reconciliation across systems.
Indian GST compliance required significant manual effort per invoice with no centralised e-invoicing workflow.
HR and payroll processing was entirely manual, prone to errors, and not integrated with attendance data.
End-to-End ERPNext Implementation
AtlasProds delivered a fully integrated ERPNext system across five core modules, configured for Indian statutory compliance and customised for the specific workflows of solar panel manufacturing.
Manufacturing
BOM management, work orders, production planning, and quality control tailored to solar panel assembly lines.
Accounting & Finance
GST-ready ledgers, accounts payable/receivable, and automated bank reconciliation.
Procurement
Purchase requisitions, vendor management, and landed cost tracking for imported components.
Inventory & Warehouse
Multi-location warehouse management with serial and batch tracking for panels and inverters.
HR & Payroll
Attendance, leave management, and Indian statutory payroll (PF, ESI, TDS) for 100+ employees.
HRMS Mobile PWA Extension
Built a mobile-optimised Progressive Web App extending ERPNext's native HRMS module. The PWA introduces mandatory selfie capture on every employee check-in, ensuring attendance entries are tied to a verifiable photo - eliminating proxy attendance and giving HR a reliable audit trail without additional hardware.
On-Premise Hosting & Offshore Backups
Deployed and configured ERPNext on the client's on-premise infrastructure. Set up automated offshore backup schedules to a remote location, ensuring data durability and disaster recovery readiness independent of local hardware failures.
11-Week Delivery

Discovery & Audit
Mapped all existing processes across procurement, manufacturing, finance, and HR. Identified integration points and data migration requirements.
Weeks 35
Configuration
Set up chart of accounts, item masters, warehouses, BOM structures, and user roles. Configured GST tax templates and e-invoicing credentials.
Weeks 68
Customisation
Built custom print formats for sales invoices and purchase orders. Developed automated reorder alerts for critical raw materials and a custom production dashboard.
Weeks 910
Data Migration & Training
Migrated historical accounting data, open purchase orders, and item master records. Conducted department-wise training for 100+ users across all roles.
Week 11
Go Live
Full parallel run followed by cutover. All five modules went live simultaneously with a dedicated on-site hypercare team for the first two weeks.
One System. Five Departments. Zero Silos.
All 100+ employees across procurement, manufacturing, finance, HR, and management onboarded to a single ERPNext instance.
Real-time raw material stock visibility eliminated production stoppages caused by unplanned stockouts.
Month-end finance close time reduced dramatically by eliminating cross-system reconciliation.
GST and e-invoicing compliance automated from day one - every invoice generated is GSTN-validated.
HR payroll processing fully automated with Indian statutory deductions (PF, ESI, PT, TDS) calculated and payslips generated in ERPNext.
ERPNext runs on the client's own on-premise servers, keeping all business data in-house. Automated offshore backups run on a regular schedule, providing reliable disaster recovery without dependence on local hardware alone.
