From SAP Hana Limitations to ERPNext Freedom
A Precious Metals Manufacturing Story - Custom Solutions for Live Metal Rates, Tray-Level Inventory, and Multi-Branch Operations
Jewellery Alloy Manufacturing
"Implementation": 6 months
Key Results Achieved
The Challenge: SAP Limitations Holding Back Growth
Precious Alloys Pvt Ltd is a trusted leader in manufacturing and supplying premium metal alloys. However, SAP's rigid structure couldn't address their industry-specific needs.
Industry-Specific Requirements Unmet
The specific requirements of the metals business, such as live metal rates, tray-level inventory, job work accounting, and currency-based client segmentation, did not align with SAP's standard procedures.
- Live metal rate pricing not supported
- Tray-level inventory tracking impossible
- Job work accounting limitations
- Currency-based client segmentation issues
Expensive and Difficult Customization
Customisation was difficult, as adding a simple custom field or creating a new print format required consultants and significant costs.
- Simple changes required external consultants
- High costs for minor customizations
- Long lead times for modifications
- Dependency on expensive SAP specialists
Multiple Disconnected Systems
They operated several systems but SAP couldn't bring them together under one unified system, making consolidated reporting and management a nightmare.
- Fragmented data across systems
- No consolidated reporting
- Management visibility challenges
- Manual data reconciliation required
Manual Pricing Calculations
Sales teams used live metal rates to calculate prices in Excel, which they then entered into SAP. It was frustrating, time-consuming, and prone to mistakes.
- Excel-based price calculations
- Manual data entry into SAP
- Error-prone pricing process
- Time wasted on repetitive tasks
No Mobile Accessibility
Due to a lack of mobile applications, their HR and sales team were stuck at desks.
- No mobile app support
- Teams tied to desktop systems
- Limited field sales capabilities
- HR processes desk-bound
Expensive Per-User Licensing
Every time a new user was added, licensing costs went up, making it expensive to scale.
- High per-user licensing costs
- Scaling limitations
- Budget constraints on growth
- Cost unpredictability
Foreign Currency Challenges
Managing foreign currency transactions and exchange rates was complex and manual.
- Manual exchange rate updates
- Currency conversion errors
- No automated rate fetching
- Compliance challenges
Warehouse-Level Tracking Only
They needed to track inventory down to the tray level across multiple branches, but SAP only supported warehouse-level tracking, which made accurate stock control very difficult.
- Only warehouse-level visibility
- No tray-level granularity
- Inaccurate stock control
- Multi-branch tracking issues
Business Impact Before Implementation
Benefits
Key advantages achieved through the ERPNext implementation
A custom pricing module was built that auto-fetches live metal rates and calculates sales prices instantly
Custom workflows now handle labour charges, approval routing for loss-making quotations, and job work accounting that doesn't hit their books incorrectly
Using API-based rate fetching with schedulers, an automated currency exchange list was implemented in ERPNext. This list includes spread-based rate calculation for EUR–INR and USD–INR and vice versa, and exchange rates are applied to every transaction
Customers and suppliers auto-filter based on currency and branch, dramatically reducing manual selection errors
Smart controls and approvals that provide real-time credit visibility, strict user permissions, and automatic invoice naming based on their conventions
Powerful custom reports, including COGS and batch-wise profit reports, Other Metal Variance Report, MSME compliance reports, forex and currency-based tracking reports, and detailed MRP reports with custom reorder logic
They implemented inventory dimensions at the tray level. Now items are properly divided by branch AND tray, giving them precise stock visibility
Reliable mobile apps that let the sales team work from anywhere and employees easily manage attendance, leave, and expenses on the go
