## Steps

1. Open the product (Products → search → the product) and press Add stock.
2. Type the quantity in the primary unit and the buying price per unit.
3. Optional: batch number, manufacturing and expiry dates, and this batch's own MRP or sale price if they differ.
4. Save. The batch appears under the product with its quantity; the stock report values it at the buying price.

## Tips

- Sales take from the oldest batch with stock first unless the counter picks another.
- A purchase from a supplier (Purchases → New) adds the batches for every line at once and records what you owe the supplier.
