Indirect materials play a crucial role in the daily operations of businesses, often serving as the unsung backbone that supports seamless production and service delivery. Items such as office supplies, repair tools, and safety equipment are essential for maintaining efficient day-to-day operations.
While indirect materials may not be directly involved in the production of finished goods, they are vital for ensuring that industries operate smoothly and effectively. Effective management of these materials contributes to streamlined workflows, improved cost control, and minimized disruptions across organizations.
Understanding the significance of indirect materials is essential for businesses, as they can account for a substantial portion—up to 90%—of a company’s total materials costs. By adopting strategic procurement practices, organizations can enhance their supply chain resilience, advance sustainability initiatives, and achieve cost reductions.
What Are Indirect Materials?
Indirect materials are essential to ensuring production processes run smoothly and efficiently. Often categorized under indirect material management, these costs are not immediately associated with the production of tangible goods. In accounting, such costs are referred to as indirect materials, which can either be part of manufacturing overhead or expensed immediately as incurred, depending on the company’s accounting practices.
Consumables including lubricants, disposable gloves, and cleaning supplies are critical for the efficient use of resources. They support keeping production running at maximum efficiency and help maintain smooth operations. While they don’t end up in the final product, their role in the overall manufacturing process is indispensable.
The value of indirect materials goes deeper than operational efficiency. They are critical for protecting worker health. Personal protective equipment (PPE), such as helmets, gloves and goggles, are all considered indirect materials. These vital tools protect workers from hazards in dangerous workplaces.
The challenge lies in their traceability: indirect materials cannot be linked to specific jobs or products, complicating cost allocation. As a solution, many companies are adopting centralized inventory management software and indirect material optimization technologies to track their usage and minimize wastefulness.

Procurement Processes for Indirect Materials

The procurement process for indirect materials management in manufacturing involves several critical steps to ensure that essential supplies, including raw materials and indirect material optimization technologies, are acquired efficiently and effectively.
1. Needs Recognition
Identify and assess the specific indirect materials required for manufacturing operations, such as maintenance tools, safety equipment, and office supplies. This step involves collaboration with various departments to understand their needs.
2. Purchase Requisition
Create a purchase requisition (PR), which is an internal document that outlines the requested materials, quantities, and justifications. This document is submitted for approval to ensure that the procurement team can proceed with sourcing.
3. Requisition Review
The procurement team reviews the purchase requisition to verify the necessity of the requested items and check budget availability. Approved requisitions move forward in the process, while rejected requests are returned with feedback.
4. Supplier Research and Selection
Conduct research to identify potential suppliers for the indirect materials needed. This may involve sending out requests for quotations (RFQs) to multiple suppliers to gather pricing and terms.
5. Evaluation and Negotiation
Evaluate supplier responses based on criteria such as cost, quality, delivery timelines, and reliability. Engage in negotiations with selected suppliers to finalize pricing and contract terms.
6. Purchase Order Creation
Once a supplier is chosen, create a purchase order (PO) that formalizes the agreement. The PO should include details such as item descriptions, quantities, prices, and delivery schedules.
7. Order Management
Monitor the order status to ensure timely delivery of indirect materials. Upon receipt, inspect the items to confirm they meet quality standards and match the specifications outlined in the PO.
8. Invoice Processing
Review supplier invoices against the purchase order and received goods to ensure accuracy through a three-way matching process (PO, goods receipt note, and invoice). Approve invoices for payment once discrepancies are resolved.
9. Record Keeping
Maintain comprehensive records of all procurement activities related to indirect materials, including purchase requisitions, orders, invoices, and supplier evaluations. This documentation supports auditing and compliance efforts.
10. Supplier Performance Evaluation
Regularly assess supplier performance based on delivery reliability, quality of materials supplied, and overall service levels. Use this information to inform future procurement decisions and improve supplier relationships.
Challenges in Managing Indirect Materials
Lack of Visibility in Procurement
One significant challenge in managing indirect materials is the lack of visibility in procurement processes. Indirect materials, such as maintenance supplies and personal protective equipment (PPE), are essential for maintaining smooth operations but often go unnoticed. Consequently, this lack of oversight can lead to inefficiencies, including overstocking or understocking, which disrupt workflows and inflate costs. For instance, a manufacturing plant may find itself with excessive cleaning supplies due to poor materials management processes, tying up capital unnecessarily, or may run out of critical spare parts, resulting in costly downtime.
Inefficient Cost Tracking
Another challenge is the ineffective tracking of indirect materials costs, which can account for a substantial portion of overall budgets. Moreover, maverick spending—purchases made outside formal procurement channels—exacerbates this issue, leading to overspending and misallocation of resources. For example, different departments might procure the same raw materials multiple times, resulting in unnecessary duplications.
Supplier Dependence and Risks
Furthermore, over-reliance on specific suppliers for indirect materials presents significant risks, including supply disruptions and price fluctuations. For example, a manufacturing facility that depends exclusively on a single supplier for maintenance tools or safety equipment may experience operational delays if that supplier faces production issues or logistical challenges, affecting the overall manufacturing process and creating vulnerabilities that adversely impact production efficiency and continuity.
