There are three **main** types of entries:

* **Purchase Receipt**: Items received from Suppliers against Purchase Orders.
* **Stock Entry**: Items transferred from one Warehouse to another.
* **Delivery Note**: Items shipped to Customers.

Apart from these core transactions, there are other documents available in ActiveBooks Stock module to manage Stock Reconciliation, Item Prices, deliveries, serial numbers, batch numbers, quality inspections, returns, etc.
