Core Assortment in Procurement: Why Less Choice Often Saves More Money
by Anna Ullmann on Jun 12, 2026Procurement & Purchasing
Why less choice often saves more money and how companies can make their procurement more efficient through standardized products.
What is a core assortment?
A core assortment is a defined selection of products that employees should preferentially use in their daily work.
Instead of choosing from hundreds of similar products, the company focuses on a manageable number of proven items.

Why do companies introduce core assortments?
In many companies, employees order the same products in numerous variations.
- Ten different ballpoint pens
- Five different copy papers
- Several brands of paper towels
This leads to higher process costs, additional administrative effort, and lower purchase volumes per item.
A core assortment creates clear standards and ensures greater transparency in purchasing.
What are the advantages of a core assortment?
Less search effort
Employees don't have to compare products anew with each order. The appropriate items are already defined.
Higher purchase volumes
When many employees use the same products, the order quantity per item increases, and better conditions become possible.
Fewer incorrect orders
Standardized products reduce queries, mistaken purchases, and unnecessary complaints.
Faster procurement
Orders can be placed, checked, and approved significantly faster.
Simplified inventory management
Fewer different items mean:
- lower storage requirements
- better overview
- easier reordering
- less capital tied up

How to create a core assortment?
Step 1: Analyze purchasing data
- Which products are ordered most frequently?
- Which items generate many individual orders?
- Where do many variants exist?
Step 2: Define standards
Select products that are reliably available, meet requirements, and are economically viable.
Step 3: Involve employees
Acceptance significantly increases when affected departments are involved early on.
Step 4: Review regularly
Needs change. Therefore, the core assortment should be updated regularly.
Common mistakes with core assortments
Too many exceptions
If every employee receives special requests, the core assortment loses its usefulness.
Too large assortments
A core assortment should reduce choice, not just rename it.
Lack of communication
Employees should understand why standards are introduced and what benefits they bring.
Core assortment and digital procurement
Many companies store their core assortments directly in the procurement system or B2B shop.
Employees automatically see the preferred items and order them with a few clicks.
- Individual price lists
- Approval processes
- Order histories
- Cost centers
- Fixed assortments
Conclusion
A core assortment is one of the simplest measures to reduce process costs and simplify purchasing.
Fewer variants mean less effort, a better overview, and often better purchasing conditions.
Especially for frequently needed C-items, a well-thought-out core assortment can enable significant savings.
