# Serial Management

When a client calls about a faulty laptop or a warranty claim, you need to know exactly which unit you sold them and on which order. Serial Management in OrderEazi lists every serial number linked to a project, with its product. You can search by serial number, project, or product, and see any extra details recorded against a serial.

### Before you start

You'll need the **View Serials** or **Manage Serials** permission, in the **Inventory** permission group. Serial numbers are only tracked for products with **Requires Serial** ticked on the product screen.

### How to find a serial number

1. In the main menu, go to **Products** > **Serial Management**.
2. In **Search Term:**, enter a serial number, project number, product code, or description.
3. Select **Filter**.

The list shows each **Serial Number** with its **Product Code**, **Product Description**, and **Project**. Only serials that have been allocated to a project are listed. To see a serial's extra details, open the menu at the end of its row: **Serial Key/Value Detail** shows each **Key** and **Value**, such as a warranty date.

**Example:** A client returns a laptop with serial SN-48213. You search for SN-48213 and find it on project PRO004512, as product LAP-14-PRO. You open the project to see the invoice and delivery date.

### How serial numbers get onto a project

1. On the project's **Costing** tab, open the menu on a line for a serialised product.
2. Select **Allocate Serials**. The badge shows how many are allocated out of the line's quantity.
3. In each **Serial Number** box, start typing and choose the serial. The search starts after 3 characters.

You see "Saved!" once the serial is linked. Each serial must already exist for that product. If it doesn't, you see "Please ensure that serial exists for the selected product." To unlink one, remove it and confirm. On a completed or cancelled project, the option is **View Serials**, and you can only look.

### How to export serial numbers

Select **Export** to download an Excel file with a **Serials** sheet, listing each serial, product, and project.
