Serialised inventory management
Serialised inventory management holds one record per physical unit, identified by a serial number, instead of a quantity per product line, so each unit carries its own cost, custody and history.
Serialised and SKU inventory are not competing features. They are different shapes of record, and the choice is far easier to make now than to undo later.
The difference in one line
SKU inventory holds a quantity against a product: 42 of SKU-1183. Serialised inventory, also spelled serialized, holds a row for every unit, each with its own identifier.
SKU inventory is efficient and right for anything interchangeable. One row however many you hold, and reordering is simple arithmetic.
Serialised inventory costs more to store and answers questions a quantity cannot:
- which unit did this customer buy, and what did we make on it
- who was holding the one that is missing
- is this specific unit still under warranty
- which units came off the delivery the supplier is disputing
When you need it
Serialise when units are individually identifiable and individually valuable, when staff carry them rather than the stock sitting on a shelf, or when after-sales service attaches to the specific unit. Phones, motorbikes, solar equipment, meters, medical devices, high-value tools.
Do not serialise sugar, screws or airtime. Any system that forces it on you for those is making your life harder for no return.
Most businesses need both
A phone shop sells handsets by IMEI and cases by the dozen. In StockRada that is a per-category decision. A category states whether each unit needs a unique identifier, what it is called, and how it is checked. Handsets require an IMEI. Cases require nothing.
What it unlocks
Once every unit is identified, the useful reporting follows without extra work. True cost of goods on each sale, honest margin, stock ageing per unit, shrinkage you can attribute to a person and a date, and warranty cover you can check rather than argue about.

Questions people ask
What is serialised inventory?
Serialised inventory holds one record per physical unit, identified by a serial number, rather than a quantity per product. Each unit carries its own cost, custody and history, so you can answer which one rather than how many.
When should I use serialised inventory?
When units are individually identifiable and individually valuable, when staff carry them rather than the stock sitting on a shelf, or when after-sales service attaches to the specific unit. Phones, motorbikes, solar equipment, meters and medical devices, not sugar or screws.
Can one workspace hold both serialised and loose stock?
Yes. It is set per category, so handsets can require an IMEI while accessories require nothing at all.
