What's an item in Serializer?

An item represents a single, individually trackable unit of a product. While a product or variant may be sold in multiple quantities, each item contains unique information that distinguishes it from every other unit of the same product.

Items are typically used when you need to track or store per-unit data such as:

• Serial numbers

• Auto-generated item IDs (can be used as serial numbers)

• Warranty duration

• Custom fields, specific to that unit, e.g. condition, IMEI, certification code, batch or lot numbers, etc.

Example

You sell a camera and a customer buys 2 of the same camera.

• The product is the camera

• The variant might be the colour or model

• Each physical camera is stored as a separate item

Each item can have its own serial number and warranty, even though they are the same product.

Why items matter

Items allow you to:

• Track individual products before and after purchase

• Register warranties per unit

• Store custom per-unit details without affecting other units

In short, items let you track what happens to each individual product, not just the product as a whole.
