[Back](./) # Why do I see ‘Accounting Stock’ and ‘Physical Stock’ in place of ‘Available Stock’ while creating transactions? Zoho Inventory provides two methods of stock tracking: * **Accounting Stock:** This represents the stock level in your books upon recording a transaction. The accounting stock of an item, increases whenever you record _Bills_ and decreases when you create _Invoices_. * **Physical Stock:** This indicates the stock level in your inventory when you physically move the stock from/to your warehouse. The physical stock of an item increases when you record _Purchase receives_ and decreases when you create _Shipments_. The _Quantity_ section of your sales/purchase transactions shows you the remaining stock for that item based on your preferred mode of stock tracking. When you change the mode of stock tracking, it will correspondingly get reflected while initiating a new transaction.
