{ "_label": "Perpetual Inventory" }

In perpetual inventory, system creates accounting entries for each stock transactions, so that stock and account balance will always remain same. The account balance will be posted against their respective account heads for each Warehouse. On saving of a Warehouse, the system will automatically create an account head with the same name as warehouse. As account balance is maintained for each Warehouse, you should create Warehouses, based on the type of items (Current / Fixed Assets) it stores.

At the time of items received in a particular warehouse, the balance of asset account (linked to that warehouse) will be increased. Similarly when you deliver some items from that warehouse, an expense will be booked and the asset account will be reduced, based on the valuation amount of those items.

Activation
