Economical Office Supplies Procurement: Price, Process Costs, and Core Ranges

In a nutshell

It's not the cent amount per pen, but supplier management, invoice processing, and search efforts that drive the actual costs of office supplies. A fixed core range of regularly used items precisely reduces these process costs.

When it comes to office supplies, attention is often paid to cent amounts. In practice, however, larger costs often arise from search efforts, supplier management, individual orders, and invoice processing.

Why process costs are important

  • new suppliers need to be set up
  • invoices need to be checked and booked
  • employees search for suitable items
  • orders are placed in too small quantities
  • stock shortages cause interruptions

Core assortments create clarity

A core assortment consists of items that are regularly needed. This includes, for example, paper, folders, pens, toner, labels, and shipping materials.

Frequently Asked Questions

Why is the unit price often not the decisive criterion?

Because the effort for ordering, invoice processing, and supplier management for many small orders usually exceeds the savings in unit price.

How large should a core assortment be?

It should cover the recurring basic needs with as few variants per product group as possible; more choice only increases administrative effort.

Who should define the core assortment?

Ideally, a central department in purchasing or administration, which is also responsible for subsequent maintenance and reordering.
