For manufacturers & factories
Manufacturing and BOM software for small units and factories
Give every product a Bill of Materials. SMI Books makes sub-assemblies, consumes raw material, values finished goods at their real cost and posts the accounts.
In one line
What is BOM manufacturing software?
BOM manufacturing software records what goes into each product and uses it to move stock and cost when you produce. SMI Books adds multi-level BOM, separate raw-material, WIP and finished-goods accounts, and GST billing in the same app.
Bill of Materials
Set it up once per product
Materials and quantities per unit, plus labour, logistics, electricity and other overhead — the recipe the app uses every time you produce.
- Materials in any unit (KG/GM, LTR/ML, PCS, METER)
- Labour, electricity, logistics, other overhead
- Multi-level: products made from sub-assemblies
- Multi-level roll-up view of the whole tree

Production
Produce — stock and cost update together
Enter how many to make. Short sub-assemblies are produced first, raw material is consumed and finished goods are added at their true cost.
- Refused cleanly if material is short — nothing half-saved
- Actual-used quantities when they differ from the BOM
- Production history with cost per unit
- Manufacturing and consumption reports

Factory accounts
Raw material to COGS, in the books
Raw material, work-in-progress and finished goods are separate inventory accounts. Overhead is absorbed into cost and COGS is posted when you sell.
- RM, WIP and FG inventory accounts
- Overhead absorbed into production cost
- Standard cost and variance (Factory plan)
- Profit & loss that shows real margins

Questions
Frequently asked
Does SMI Books support Bill of Materials and multi-level BOM?
Yes, on the manufacturing plans. Each product can have a BOM with materials, labour and overhead. During a production run any sub-assembly that is short is produced first automatically, then raw material is consumed and finished goods are added to stock.
Is it proper double-entry accounting?
Yes. Every invoice, bill, payment, expense and production run posts its own double-entry journal, so you get a day book, ledgers, trial balance, profit & loss and balance sheet without typing journals.
How much does SMI Books cost?
Plans start at ₹149 a month plus 18% GST for a retail shop and go up to ₹599 a month for a full factory. Yearly plans save about 8%. Every new business gets a 30-day free trial of all features.
