When organizations look for procurement savings, the focus is often on price. However, in our experience, costs are rarely driven by price alone. They are also shaped by the number of suppliers a business manages and the number of stock keeping units (SKU)s it carries.
Over the last few years, we have repeatedly seen supplier fragmentation and SKU proliferation create hidden costs across the value chain. These costs are hidden because they do not appear in one clear budget line. Instead, they are spread across activities such as supplier onboarding, order processing, planning, quality management, inventory holding, production changeovers, and logistics.
What often starts as a way to increase flexibility, improve service or offer more customer choice can gradually create additional complexity. Over time, that complexity becomes a structural cost driver that impacts both performance and profitability.
Where Complexity Creates Cost
The financial impact of supplier and SKU complexity is often underestimated because it is distributed across multiple functions. Procurement, supply chain, manufacturing, warehousing, transport and commercial teams all absorb part of the burden.
A fragmented supplier base increases effort and reduces leverage. At the same time, a broad SKU portfolio introduces operational complexity throughout the value chain, often resulting in:
- More administrative effort, driven by additional supplier management, order processing and contract administration
- Higher operational complexity, through increased planning requirements, production changeovers and quality management activities
- Higher inventory levels, caused by lower forecast accuracy and a wider range of products to manage
- Reduced agility, making it more difficult to respond quickly to changing market conditions
When organizations take an end-to-end view, they often discover that complexity is eroding margins, tying up working capital and limiting operational flexibility.
Why the Challenge is Becoming More Urgent
The cost of complexity has become increasingly visible in recent years. Supply disruption, inflation, and growing resilience requirements have exposed the true cost of unmanaged complexity.
Businesses with a scattered supplier base, too many specifications, or too many low-value variants are harder to steer and slower to adapt. At the same time, complexity creates competing priorities across functions. Procurement may seek supplier consolidation to improve leverage, operations may push for standardization to increase efficiency, while commercial teams often advocate for greater product variety to meet customer needs. Without strong governance, complexity tends to grow by default.
Simplification Without Oversimplifying
Reducing complexity does not mean eliminating choice or consolidating suppliers at all costs. The objective is to understand which complexity creates value and which complexity creates cost.
Organizations that successfully address supplier and SKU complexity typically focus on a combination of initiatives:
- SKU rationalisation, removing low-value or low-volume products
- Supplier consolidation, where it improves leverage and reduces management effort
- Specification standardisation, reducing unnecessary variation across products and materials
- Tail spend management, increasing visibility and control over low-value purchasing activities
The most effective decisions are based on total value creation rather than unit price alone, balancing efficiency, resilience, service and growth objectives.
The Value of Managing Complexity
Addressing supplier and SKU complexity effectively delivers benefits beyond procurement savings. Clients can improve margin, reduce working capital, simplify operations, strengthen supplier management, and build a more resilient operating model. In many cases, this also improves cost, service, and cash performance.
Perhaps most importantly, simplification creates a more agile and resilient operating model. By reducing unnecessary complexity, businesses can respond faster to market changes while maintaining control over costs and service levels.
At Argon & Co, as supply chain and procurement experts, we help clients make supplier and SKU complexity visible, understand its true cost, and focus on the biggest opportunities. We assess the impact across sourcing, inventory, production, logistics, and service so decisions are based on total value, not just unit price. We then identify where simplification will have the greatest effect, whether through SKU rationalisation, supplier consolidation, specification standardisation, or tighter control of tail spend. Our objective is to reduce unproductive complexity while protecting what is necessary for resilience, service, and growth.
