As discussed in the Item page, if an Item is serialized, a Serial Number (Serial No) record is maintained for each quantity of that Item. This information helps track the location of the Serial No, its warranty and end-of-life (expiry) information.

You can also track from which Supplier you purchased the Serial No and to which Customer you have sold it. The Serial No status will tell you its current inventory status.

If your Item is serialized you will have to enter the Serial Nos in the related column with each Serial No in a new line. You can maintain single units of serialized items using Serial Number.

To access the Serial Number list, go to:

Home > Stock > Serial No and Batch > Serial No

1. Prerequisites

Before creating and using a Serial Number, it is advised that you create the following first:

1. Item
2. Enable 'Has Serial No' in the Item master 

2. How to create a Serial Number

Usually, Serial Numbers are auto-created when transactions are made against a serialized Item. This works only when 'Has Serial No' is enabled and a series is set in the Item master.

For example, a series was set for the following Item as 'PB2L.#####'. Then a Stock Entry was submitted to receive the Item. The Serial Numbers were created accordingly.

However, if you want to create a Serial No manually follow these steps:

1. Go to the Serial Number list, click on New.
2. Enter a Serial Number.
3. Enter the Item Code and details will be fetched.
4. If any transaction is done with an item, Serial No cannot be set or unset.
5. Save.

Inventory of an Item can only be affected if the Serial No is transacted via a Stock transaction (Stock Entry, Purchase Receipt, Delivery Note, Sales Invoice). When a new Serial No is created directly, its Warehouse cannot be set.

2.1 Notes about Serial Number

1. The Status is set based on Stock Entry.
2. Only Serial Numbers with status 'Available' can be delivered.
3. Serial Nos can automatically be created from a Stock Entry or Purchase Receipt. If you mention Serial No in the Serial Nos column, it will automatically create those serial Nos.
4. If in the Item Master, the Serial No Series is mentioned, you can leave the Serial No column blank in a Stock Entry / Purchase Receipt. Serial Nos will automatically be set from that series.
