ERPNext Subcontracting – Complete Guide to Outsourced Manufacturing Control
Introduction
Manufacturers commonly use subcontracting to outsource part or all of the production process to external vendors. This approach improves flexibility and scalability but often creates challenges such as material visibility gaps, inaccurate costing, delayed tracking, and manual reconciliation. ERPNext Subcontracting addresses these challenges by bringing outsourced manufacturing into the same system as in-house production. The system lets businesses track raw materials issued to subcontractors, monitor consumption, manage inward receipts, and maintain accurate production costs in real time.
What Is Subcontracting in ERPNext?
Subcontracting in ERPNext allows a company to:
- Send raw materials to a subcontractor
- Track materials while they remain outside the company’s premises.
- Receive finished or semi-finished goods
- Automatically record material consumption and costs
Unlike manual job-work tracking, ERPNext actively manages subcontracting through a structured manufacturing workflow and delivers full traceability and clear accountability.
Subcontracting Workflow in ERPNext
1. Subcontracting Setup
Before starting subcontracted production, ERPNext requires a structured setup:
- Subcontractors are defined as Suppliers
- Subcontracted items are linked to Bills of Materials (BOMs)
- Dedicated subcontractor warehouses are configured
- Subcontracting settings define how materials and costs are handled
This setup ensures all movements are system-controlled rather than manually tracked.
2. Issuing Raw Materials to Subcontractor
When production is outsourced:
- Raw materials are issued from the company’s warehouse
- Stock is transferred to a subcontractor-specific warehouse
- Ownership of material remains with the company
- Quantity and valuation are tracked continuously
This ensures businesses always know:
- How much material is with each subcontractor
- What quantity is available, consumed, or pending
Subcontracting Inward in ERPNext
What Is Subcontracting Inward?
Subcontracting Inward records the receipt of finished or semi-finished goods from the subcontractor after job work completion.
This step is critical because it:
- Confirms production completion
- Records raw material consumption
- Updates finished goods inventory
- Triggers accounting and costing entries
How ERPNext Handles Subcontracting Inward
Create a subcontracting inward entry:
- The system adds finished goods to stock
- The system automatically deducts raw materials based on the BOM
- The system adjusts subcontractor warehouse stock
- The system records job work charges
- The system calculates the final product cost accurately
This removes the need for:
- Manual consumption calculations
- Spreadsheet-based reconciliations
- Post-production cost corrections
Key Features of ERPNext Subcontracting
Material Traceability
Every unit of raw material sent outside the organization is fully traceable until it returns as a finished product.
BOM-Based Consumption
BOMs drive material usage, ensuring consistency and preventing overconsumption.
Subcontractor Inventory Control
Dedicated subcontractor warehouses provide clear visibility into material balances at each vendor location.
Accurate Costing
Final product cost includes:
- Raw material valuation
- Subcontracting charges
- Additional landed costs (if applicable)
Seamless Integration
Subcontracting integrates directly with:
- Inventory
- Purchasing
- Manufacturing
- Accounting
Subcontracting Reports in ERPNext
ERPNext provides detailed reports to monitor outsourced production:
- Subcontractor Stock Report – material held by each subcontractor
- Issued vs Consumed Materials – usage accuracy tracking
- Pending Subcontracting Inward – production follow-up
- Subcontracting Cost Analysis – cost transparency
These reports help businesses reduce material losses, improve planning, and maintain vendor accountability.
