Understand before choosing
Class C purchasing:
understand before simplifying.
A small share of spend can conceal many requests, scattered suppliers and operations to track. Class C helps describe this situation; it does not measure a purchase's criticality on its own.
Sourcing Force + Buy Made Easy
From class C purchases to a centralised workflow.
Understanding class C is useful when the analysis helps reduce work around fragmented orders.
Sourcing Force brings one-off requests into a digital portal connected to the ERP or Source-to-Pay solution.
Buy Made Easy can become the single supplier, simplifying relationships with numerous occasional suppliers.
A useful definition
What are class C purchases?
Class C purchases form the low-spend share of a portfolio classified by expenditure value. They may involve many items, requests and suppliers. Their variety explains why purchase price alone is insufficient to choose the right process.
The term Tail spend describes fragmented expenditure beyond the largest, most structured spend areas. The concepts often overlap without a universal boundary. The scope depends on available data and your organisation's chosen rules.
The same category may represent a different share depending on the site, period or activity studied. Before classifying, specify what you are comparing: categories, suppliers, items or orders. Mixing these units can lead to misplaced priorities.
Match the approach to each class
Understanding purchasing classes
A / B / C
Select a class to compare spend profiles and oversight needs. Low value does not mean low criticality.
Combine software and outsourcingFour perspectives
Class C, indirect, spot:
each term answers a different question.
| Concept | What it describes | What it does not determine |
|---|---|---|
| Class C | A small share of the total spend value within the scope. | The operational importance of the need. |
| Tail spend | Fragmentation across the long tail of spend. | A single threshold applicable to every organisation. |
| Indirect purchase | A need that supports the organisation's operations. | Its value: an indirect purchase can be significant. |
| Spot purchase | A one-off need handled in a specific context. | Automatic classification as class C. |
These criteria can overlap. An office consumable may be indirect, recurring and class C. A one-off technical service may be a spot purchase and still be critical. These examples illustrate an analytical approach; they do not replace classification of your own spend.
Choose an indirect purchasing workflow ↗Value and impact
Low value
does not mean low criticality.
An inexpensive spare part can be essential to restarting equipment. A one-off service may address a safety requirement. Financial value does not describe the consequences of unavailability.
Three questions before choosing the workflow
- What happens if the product or service arrives too late?
- Is a qualified alternative actually available?
- Which technical, document or procurement approvals must remain in the process?
ABC classification and risk assessment complement each other. A critical need retains its requirements even when a simpler workflow suits its value.
From findings to action
Start with requests,
then choose the approach.
BME's white paper combines spend analysis with process observation. This perspective avoids treating every situation in the same way.
Define the portfolio
Choose a consistent period and scope. Gather available orders, suppliers and categories. Identify data quality gaps before comparing sites.
Observe the actual work
Follow a request from the initial need through to invoice processing. Identify searches, data re-entry, discussions and exceptions that take up team time.
Adapt the workflow
A recurring need can move to a catalogue; an existing quote can follow a documented workflow; an operation to delegate can be assigned to BME within an agreed scope.
Track priorities
Choose useful indicators: supplier fragmentation, recurring needs, request volumes or data quality. Their interpretation should lead to an identifiable action.
One portal, several purchasing workflows
Centralise class C purchases
MRO and industrial supplies
Technical specifications, urgent requirements and multiple distributors make small industrial orders difficult to manage.
Explore the process →
Personal protective equipment
An order for gloves or footwear still needs the right size, product reference and specifications for the task.
Explore the process →
Testing, measurement and certification
Without a defined deliverable, method and deadline, a one-off testing service becomes difficult to accept on completion.
Explore the process →
Heating, ventilation and air conditioning
Technicians need parts and services quickly while allocating each purchase to the right site or project.
Explore the process →
Pallets and handling
Separate orders for each warehouse make specifications and delivery dates difficult to reconcile.
Explore the process →
Small IT equipment
Adapters, monitors and peripherals are often bought urgently from several distributors.
Explore the process →
Point-of-sale displays and marketing
A marketing campaign brings together printing, point-of-sale displays and promotional items from different suppliers.
Explore the process →
Freelancers and services
A one-off assignment becomes harder to track when requirements, deliverables and approvals are scattered across separate conversations.

Business travel and events
Hotels, venues, transport and MICE services create fragmented bookings, sometimes committed outside the procurement process.

A specialist application.
Services to suit your needs.
Sourcing Force organises class C purchasing and tail spend workflows alongside your existing environment. The ERP or S2P remains the system of record for rules, approvals, commitments and orders.
Assess tail spend procurement management ↗Outsourcing is an operational choice
BME Consulting provides outsourcing services for assigned operations. The application and services can be used together or separately. Class C classification alone transfers no responsibility.
Define assigned tasks, decision limits and information to share. You can then compare scenarios with procurement, site teams and IT.
Scope indirect procurement outsourcing ↗Your next step
Make tail spend understandable.
Start with a scope your teams can explain. The free Tail Spend Assessment opens a discussion about fragmented spend, workflows and priorities. The aim is to choose a suitable process for each need without applying a theoretical ratio or saving to the whole company.
Prepare your project
Implementation questions.
Is there a universal euro threshold for class C purchases?
No. Classification depends on the scope, period and distribution of the spend analysed. Your organisation defines its thresholds; assess the criticality of the need separately.
Should every class C purchase be outsourced?
No. A catalogue may suit a recurring need, a quote-based workflow a one-off purchase, and a BME service the operations you choose to assign. Classification helps select a process; it does not decide outsourcing on its own.
Can a low-value part still be a priority?
Yes. An inexpensive part can be essential to business continuity. Assess availability, acceptable lead time and the consequences of a shortage before choosing its purchasing workflow.
