ABC inventory analysis: what it is and how to use it
Not every part in stock deserves the same level of attention. Some move every week and account for much of the money invested; others sit on the shelf for months. Treating them all the same wastes time and money. ABC inventory analysis is the tool that separates priorities from items that can be managed more simply. Here is what it is and how to use it in your shop.
What ABC inventory analysis is
ABC analysis is a classification technique that shows the relative importance of each item in inventory. It starts from the premise that items do not carry the same weight in the business's results and divides them into three categories based on each item's value or impact:
- class A: a few items that account for most of the value or usage
- class B: items of intermediate importance
- class C: many items that together represent a small share of the value.

Benefits of ABC analysis for your shop
Prioritizing resources
The analysis shows which inventory items deserve more attention and resources because they have more value or impact on the business.
Cost control
By focusing on higher-value items, the shop finds opportunities to cut costs, whether through better supplier negotiations or more efficient management of those items.
Demand planning
Classification helps identify the fastest-moving items, which need closer control. That prevents overstock and shortages and improves service. ABC analysis is a key part of supplies management at the repair shop.
How to use ABC analysis in your shop
Collect and analyze data
Gather accurate information on the value and demand of each item. Repair shop software with inventory management makes this easier. Keep the data updated to reflect changes in demand and prices.
Classify items
With the data in hand, split items into classes A, B and C according to their value or impact on the business. In practice, A items are the most important or most used by the shop, and C items appear only in a few jobs.
Define actions for each class
Class A items need close tracking, careful negotiation and frequent control. Class C items can be managed more simply. Create specific strategies for each group.
Review regularly
Classifications change over time. Review the curve regularly and adjust strategies as demand and prices change. Adapt the technique to your shop's reality.
