# Serial items and stock status

Here you'll get an easy understanding of serial items and their stock management/status.

In Customers 1st, it's easy to keep track of each individual serial item. Both when it comes to stock status and inventory management.

## Overview of serial items and their stock status

In the **Items** section on the left side, you'll find an overview of all your items. To show only serial items, just go to the **Choose filter** box and tick **Has serial number**.

As you can see in the picture, we have 3 bikes that are all **Serial items**.

We have one of **Serial item 1** and two of **Serial item 2** - serial item 2 has the same product number, but different serial numbers.  
That's why, next to Serial item 2, it says **Total: 2**, because both are in stock.

1) When a bike is sold and is no longer in stock, the status of the item will automatically update from yes to no.  
If you, as a **Serial Item 2**, have more of the same model in stock, the **Total** will also change, since there are now fewer bikes in stock with that same product number.

**2)** If a serial item gets added to a work order, the status and stock count also change:  
The serial item will still show as in stock, so the Total doesn't change.  
But it will show that the item is **Reserved**, and that there is now only 1 piece **Available**. ​

If you haven't managed to order a new bike for the customer yet, you can still create it in the system and make an order for the customer in **Work Order**.  
​

To create the bike with a different frame number, find the bike under **Items**, click the **duplicate** icon next to the bike.

You’ll get a copy of all the info you’ve filled out for the item, such as this serial item’s **size, color** or whatever else. It’ll automatically be filled out on the duplicated serial item.  
  
You’ll get a reminder that the **serial number** is identical to the previous bike. So, the old serial number needs to be swapped out with the new one, since you can’t create and/or sell the same unique bike twice.

Once you’ve changed the serial number, you can hit **Save** and that’s it—you’ve created the new bike.

When the item is saved, you can complete the sale and now the stock status will change to **backorder**. This lets you know it’s time to order a new bike, if you haven’t already.
