Bill of materials
Name the finished product and list each component with the quantity one unit uses.
BOM & work orders
BOM and work order software for small manufacturers
Write down what goes into each product once. When a work order is done, the raw material comes out of stock, the finished goods go in, and you know what each unit cost in material.
For garment and textile units, food processing, packaging and printing, furniture makers and small engineering workshops.

Components out, finished goods in, at what they cost
A work order draws each component in the bill of materials from its godown, and puts the finished units into stock at the rolled-up cost.

From recipe to finished stock
The same four things every small unit tracks on paper or in a spreadsheet, kept in one place with your stock.
Work orders
Plan a run for a quantity of a product, start it, and complete or cancel it.
Assembly
Building draws the components out of stock and puts finished goods in, in one step.
Rolled-up cost
Finished goods come into stock at the average cost of the material that went into them.
The working
What 480 tote bags cost in material
The bill of materials for one bag is 0.5 m of canvas, 1.2 m of webbing, 0.1 of a thread spool and one woven label. Work order WO-0142 is for 480 bags.
On completion, 240 m of canvas, 576 m of webbing, 48 spools and 480 labels come out of the godown, each at its average cost. The ₹50,160 total is divided by 480, so the bags go into stock at ₹104.50 each.

On the shop floor
Every run from planned to done
Work orders move through the same few steps, and the dashboard shows what is open and what material is short.
Planned
Raise a work order for a product, a quantity and the godown it builds in, with a note for the floor.
In progress
Start it when the job goes on the machines, so everyone can see what is running.
Completed
Complete it to draw the components and add the finished goods to stock at their cost.
Cancelled
Cancel a run that will not go ahead. Nothing moves in stock.

A list of the components and the quantity of each that goes into one unit of a finished product. For a tote bag that might be 0.5 m of canvas, 1.2 m of webbing, a tenth of a thread spool and one label.
The components for the full quantity are taken out of stock, the finished goods are added to stock, and an assembly record is saved with the cost per unit. The work order is marked completed.
Each component is costed at the weighted average cost of the stock you have received, multiplied by the quantity used. The total is divided by the number of units built, so every finished unit carries its material cost.
The build stops before anything moves and tells you which component is short, how much is in the godown and how much is needed. The dashboard also lists components to buy for your open work orders.
Yes. Use Assemble on the Manufacturing page to build a quantity straight away, for example when you have already made the goods and only need the stock and cost recorded.
No. It covers bills of materials, work orders and assembly for small units. It does not do capacity planning, machine scheduling or labour costing.
