The five numbers to close on every oil mill batch

An oil mill batch is useful only when the input and every output are recorded together. If one quantity sits in a paper register, your stock and margin will drift.

1. Seed consumed

Record the actual kilograms drawn from a specific seed lot. Do not use the planned quantity after the batch has run.

2. Oil produced

Record the measured output and the tank that received it. Keep the unit and density conversion consistent.

3. Cake produced

Cake is inventory, not a balancing number. Record its kilograms, grade and storage location.

4. Wastage

The difference needs a reason: moisture, handling, filter loss or another agreed category. A trend is more useful than a one-off percentage.

5. Loaded cost

Seed is the largest input, but labour, power and consumables still change the cost per litre. Close them while the shift details are available.

When these five numbers reconcile, the batch becomes a reliable source for tank stock, cake stock, costing and management reports.
