Material Master
The Material Master is the centralized database for all materials used across your projects. It defines material properties, categorization, units of measure, approved substitutes, and production recipes.
Material Database & Categorization
Every material used in procurement, inventory, and consumption must first be defined in the Material Master. Materials are organized in a hierarchical structure that supports efficient searching, reporting, and budgeting:
Material Hierarchy
- Material Group — The top-level classification (e.g., Cement, Steel, Aggregates, Electrical)
- Material Sub-Group — A secondary classification within the group (e.g., under Steel: TMT Bars, Structural Steel, MS Plates)
- Material Item — The individual material record with full specifications
The Material Master is shared across all projects in the organization. Defining a material once makes it available for all jobs, ensuring consistent naming, specifications, and units across the enterprise.
Material Properties
Each material record captures the essential attributes needed for procurement, inventory, and cost tracking:
| Field | Required | Description |
|---|---|---|
| Material Code | Required | Unique identifier for the material, auto-generated or manually assigned |
| Material Name | Required | Descriptive name of the material (e.g., "TMT Bar Fe500D 12mm") |
| Material Group | Required | Top-level category the material belongs to |
| Material Sub-Group | Optional | Secondary classification within the material group |
| Unit of Measure (UOM) | Required | Primary unit used for procurement and inventory (e.g., MT, Kg, Nos, Cum, Sqm) |
| HSN/SAC Code | Optional | Tax classification code for GST compliance |
| Specifications | Optional | Detailed technical specifications, grade, brand preferences |
| Tax Configuration | Optional | Default tax rates (CGST, SGST, IGST) applicable to the material |
Units of Measure (UOM)
JobNext supports a comprehensive set of units of measure commonly used in construction. The UOM defined in the Material Master becomes the default unit for all transactions involving that material:
- Weight — MT (Metric Tonnes), Kg, Quintal
- Volume — Cum (Cubic Metres), Litres, KL (Kilolitres)
- Area — Sqm (Square Metres), Sqft (Square Feet)
- Length — Rm (Running Metres), m (Metres)
- Count — Nos (Numbers), Set, Pair, Bag, Bundle
Material Alternates
The Material Alternates feature lets you define approved substitute materials for any primary material. When a primary material is unavailable or a vendor offers an equivalent product, alternates provide a controlled way to manage substitutions.
Setting Up Alternates
- Open the Material Master Navigate to the Material Master and select the primary material you want to configure alternates for.
- Go to the Material Alternates Tab Within the material record, switch to the Material Alternates tab to view and manage substitutes.
- Add Alternate Materials Use the "Select Material" dropdown to search for and add materials that can serve as substitutes for the primary item.
- Save the Configuration Save the record. The alternate materials are now linked to the primary material and will be visible throughout the procurement workflow.
Alternates in Procurement
Once configured, alternate materials become visible and usable in the following areas:
- Estimates — Alternates appear alongside primary materials when building cost estimates
- Material Requisitions — Site teams can see available alternates when raising demands
- RFQs & Vendor Offers — Vendors can submit offers using approved alternate materials instead of the primary item
- Purchase Orders — When an alternate is accepted in a vendor offer, it carries forward automatically into the PO
Only materials that have been pre-approved as alternates in the Material Master can be substituted during procurement. This prevents unauthorized material changes that could affect quality or compliance.
Bill of Materials (BOM)
For materials that are produced in-house (such as ready-mix concrete, hot-mix asphalt, or concrete blocks), the Bill of Materials feature defines the recipe or formula specifying the raw materials and quantities needed to produce a unit of the finished product.
BOM Structure
| Component | Required | Description |
|---|---|---|
| Parent Material | Required | The finished product being manufactured (e.g., M25 Ready-Mix Concrete) |
| Component Material | Required | Each raw material required for production (e.g., Cement, Sand, Aggregate, Water) |
| Quantity per Unit | Required | The quantity of each component needed to produce one unit of the parent material |
| UOM | Required | Unit of measure for each component quantity |
When production output is recorded in the Equipment module, the BOM is used to automatically calculate raw material consumption, deducting the correct quantities from inventory.
Best Practices
- Standardize naming conventions — Use consistent naming patterns across material groups to make searching and reporting easier
- Set up tax codes early — Configure HSN codes and tax rates during material creation to avoid manual corrections later
- Define alternates proactively — Identify and approve substitute materials before procurement begins to avoid project delays
- Maintain BOM accuracy — Keep production recipes updated to ensure accurate inventory consumption tracking
- Use sub-groups effectively — Organize materials into meaningful sub-groups to simplify filtering in MRs, RFQs, and reports
