Step 01
Pick the model
Bundle (fixed components, sell-as-one), kit (substitutable components, configured at order), BOM (light manufacturing consumption).
Item Master Software | Kits, Bundles & BOM
Bundle, kit or BOM. The right component model per item.
Bundles for sales packaging (sell as one, ship as components). Kits for substitutable assemblies. BOM for light manufacturing consumption. Each model captures component cost roll-up, GST treatment and stock movement correctly.
How it works
From component definition to invoiced sale.
Step 02
Components defined
Components, quantities, scrap factor (for BOM), substitution allowance (for kit). Versioning by date for change control.
Step 03
GST treatment resolved
Composite supply (one principal + ancillary, takes the principal rate) vs mixed supply (independent items, takes the highest rate). The system flags the treatment.
Step 04
Stock movement at sale
Bundle: components decrement at dispatch. Kit: configured components at order, decrement at dispatch. BOM: components issue at work-order start, finished good receives at closeout.
What the system does
Capability, input, output.
| Capability | Input | Output |
|---|---|---|
| Bundle definition | Components + fixed quantities | Sell-as-one with component decrement at dispatch |
| Kit configuration | Components + substitution rules | Order-time configuration with options |
| BOM definition | Components + scrap factor + version | Versioned BOM per finished good |
| Cost roll-up | Component cost + scrap | Bundle / kit / FG cost |
| GST classification | Bundle / kit composition | Composite or mixed supply flag |

Compliance + integrations
Bundled supply, classified right.
Composite vs mixed supply is a frequent GST audit finding. The system flags the classification at item creation; the tax reviewer approves before the item goes live.

Kits, Bundles & BOM FAQ
What buyers ask.
Bundle vs kit vs BOM. Which model do we pick?
Bundle: customer buys as one, components are fixed, sold for retail packaging or promotion. Kit: customer configures at order (substitution allowed), typically B2B assembly. BOM: internal manufacturing of finished goods from components. The right model drives the right stock and GL behaviour.
Composite vs mixed supply. How do we know?
Composite supply: one principal item with ancillary supplies that are naturally bundled (e.g., AMC contract with spare parts). Takes the principal rate. Mixed supply: independent items packaged together (e.g., diwali gift hamper). Takes the highest rate. The system flags both at item creation; the tax reviewer approves the classification.
Can a kit have substitutable components?
Yes. A kit definition can specify a primary component and a list of acceptable substitutes (configured at order time based on stock availability). The substitute's cost rolls up correctly; the audit trail captures the substitution decision.
