Indirect procurement: why 80% of transactions get 20% of analytical attention

Indirect procurement — covering maintenance, repair, and operations (MRO) supplies, facilities management, IT hardware, professional services, and travel — represents 15 to 27 percent of company revenue for most organizations. MRO alone accounts for 70 to 80 percent of all procurement transactions but only 5 to 10 percent of a manufacturer's cost of goods sold, according to OMNIA Partners data cited by Centerpoint Group.

Yet most procurement teams allocate their analytical resources in the opposite proportion: 80 percent of effort to direct materials, 20 percent to everything else. The mismatch is not due to incompetence. It is structural. Procurement teams are measured on direct-material savings because those are visible, contractible, and finance-validated. Indirect spend, by contrast, is fragmented across a dozen departments, purchased through multiple channels, and historically viewed as non-strategic — the lubricants, light bulbs, and consulting fees that keep the lights on but never enter the P&L as a line item anyone examines.

Why indirect spend leaks more per dollar than direct

Direct materials are concentrated. A given manufacturing category — say, aluminum sheet or steel coil — involves at most a handful of suppliers, a known market price, and a procurement specialist who owns it end-to-end. Indirect spend is the opposite: dispersed across thousands of SKUs, hundreds of suppliers, and a dozen budget holders who each buy independently.

Fragmented demand

MRO purchases are spread across maintenance, production, and facilities teams. No single person sees the total spend on fasteners, filters, or cutting tools. Each department buys independently, at different prices.

Low data visibility

Fewer than 10% of organizations have fully automated spend analysis. Most rely on manual reporting that cannot capture decentralized purchasing patterns. The Ardent Partners CPO Rising 2025 report quantifies this gap.

High transaction count

MRO generates 60-80% of all procurement transactions. High volume + low value = low strategic attention. Each transaction is small, but the aggregate is substantial.

Maverick spend is invisible

When procurement has no visibility into indirect buying decisions, end-users purchase outside contracts at unnegotiated rates. Maverick spend is the single most common reason savings forecasts fail.

The RS 2025 Indirect Procurement Report found that 62 percent of respondents cite budget pressure as their top concern, up from 31 percent in 2024. The urgency to capture indirect savings is rising, but most organizations still lack the governance infrastructure to act. The same report notes that the proportion of organizations using more than 250 MRO suppliers rose from 6 percent to 15 percent, indicating that supplier sprawl is accelerating, not contracting.

"Most category plans underperform not because the strategy was wrong but because implementation stopped short of full adoption." — Centerpoint Group

The four categories where leakage concentrates

Indirect spend is not a monolith. Four sub-categories account for the majority of leakage, each with distinct structural causes.

MRO supplies. Bearings, lubricants, safety equipment, spare parts — the items that keep production lines running. MRO is the highest-transaction-volume category in procurement, yet receives the least strategic attention. Because MRO items are often purchased reactively (a machine breaks, a part is needed immediately), emergency purchases at list price are common. The Verdantis analysis of MRO spend notes that system integration gaps between EAM, inventory, and procurement systems prevent accurate alignment between maintenance demand and material availability.

IT hardware and software. Laptops, monitors, servers, SaaS licenses, and cloud infrastructure. IT procurement sits outside most procurement teams' governance. The Gartner estimate that poor data quality costs organizations $12.9M annually applies disproportionately to IT categories because hardware configurations, license counts, and usage data are rarely maintained in the supplier master. Software procurement alone carries a 20-30 percent overpayment rate for enterprises.

Professional services. Consulting, legal, marketing, and temporary staffing. Services procurement is the most difficult category to benchmark because every engagement is scoped differently. The US contingent workforce market exceeded $200B in 2025, and most enterprises cannot verify whether contract rates are competitive or whether SOWs are being executed within scope.

Facilities management. Property leases, utilities, cleaning, security, and maintenance contracts. According to E&I Cooperative Services, colleges spend about 16.4 percent of their total budget on maintenance and operations. For manufacturing facilities, MRO spending including spare parts and services ranges from 0.5 percent to 4.5 percent of annual revenue. These categories are typically managed by facilities departments, not procurement, and renew on multi-year cycles without competitive review.

Why the 80/20 allocation is self-reinforcing

Procurement teams allocate resources where they are measured. Direct materials produce hard savings that procurement can claim and finance can validate. A 3 percent reduction in aluminum cost is a $300K saving that appears in the quarterly P&L review.

Indirect savings are harder to measure. A negotiated 10 percent discount on MRO supplies is diluted by maverick spend on items that still flow through emergency channels at list price. A consolidated IT hardware contract saves $200K in negotiated pricing, but the savings are distributed across 15 departmental budgets and attributed to nobody in particular. Finance cannot validate them, so procurement does not claim them, and no one is rewarded for achieving them.

The typical approach

Procurement ignores indirect. End-users buy independently. 250+ suppliers per category. No consolidated contracts. 15-30% leakage above negotiated rates.

Outcome: compounding invisible cost

The governed approach

Each indirect sub-category has a named owner. Spend data is automated. Contracts are enforced at point of purchase. Maverick spend is visible and addressed quarterly.

Outcome: 10-20% sustained savings

The Deloitte 2025 Global CPO Survey identifies "siloed working (57%)" and "competing priorities (46%)" as the top barriers to delivering procurement value. These numbers describe the indirect procurement problem precisely: the business units that own indirect spend do not share goals with procurement, and procurement lacks the mandate to govern what it cannot see.

What good governance looks like for indirect spend

Organizations that capture indirect savings do not use a different playbook. They apply the same governance principles that work for direct materials — category ownership, spend visibility, contract compliance — but adapted for the structural reality of indirect spend.

Visibility

Automate spend aggregation across all indirect categories. Any spend not visible cannot be managed. Target: 90%+ visibility within one quarter.

Governance

Assign named category owners for MRO, IT, services, and facilities. Each owner accountable for strategy, contracts, and compliance in their domain.

Consolidation

Reduce supplier count by 40-60% per category. Centralize high-volume, low-complexity items under single contracts with automated catalog purchasing.

Enforcement

Block non-contract purchasing at the system level. Allow exceptions only through a managed approval workflow. Report maverick spend by department monthly.

First, automated spend aggregation. Fewer than 10 percent of organizations have fully automated spend analysis, according to the Ardent Partners CPO Rising 2025 report. Manual reporting from 15 departmental systems produces a spend picture that is six months stale by the time it is compiled. Automated aggregation from procurement, AP, and card data produces a current picture in hours. Sievo emphasizes that identifying opportunities is only half the job — the real work is closing the gap between insight and execution through automated workflows.

Second, named category ownership. Each indirect sub-category needs a single accountable owner, not a committee. Centerpoint Group's category management framework assigns each category an owner "accountable for the category end-to-end the way a general manager is accountable for a business unit." This means ownership of strategy, supplier base, performance, and stakeholder alignment — not just running sourcing events.

Third, supplier consolidation with bite. The average proportion of organizations using more than 250 MRO suppliers rose from 6 percent to 15 percent. Each supplier adds administrative cost, reduces leverage, and creates opportunities for non-standard pricing. A disciplined consolidation program reducing the supplier base by 40-60 percent per category creates the volume concentration needed for meaningful negotiation leverage. Consolidation works best when paired with catalog-based purchasing that makes the preferred supplier the easiest path for end-users.

Fourth, contract enforcement through system controls. Maverick spend — purchases made outside approved suppliers, contracts, or category plans — is the single most common reason savings forecasts fail, per Centerpoint Group. The fix is structural: configure procurement systems to route all indirect purchases through catalogs and contracts. Allow exceptions only through a managed approval workflow. Report maverick spend by department to the CFO quarterly. When end-users must explain why they paid 30 percent more for the same bearing, the behavior changes.

What this means in practice

Five specific actions a CPO or procurement director can take this quarter, with expected outcomes:

Map indirect spend across all systems. Pull data from AP, procurement, P-card, and T&E systems into a single view. Most organizations discover 20-40% of indirect spend they were not tracking. Expected outcome: complete spend baseline within 6-8 weeks.
Assign category owners for MRO, IT, services, and facilities. These need not be new hires — existing category managers can add indirect categories to their portfolio if the scope is clearly bounded. Expected outcome: named accountability for 80% of indirect spend within 4 weeks.
Consolidate MRO suppliers to 3-5 per site. The current average of 250+ suppliers per organization is not value-driven. A consolidation exercise typically recovers 10-15% in year one through volume pricing and reduced administrative overhead. Expected outcome: year-one savings equal to 8-12% of current MRO spend.
Implement catalog-based purchasing for high-volume items. Move 60-70% of MRO transactions to catalog models where prices are pre-negotiated and compliance is automatic. Expected outcome: maverick spend reduction of 40-60% within two quarters.
Report indirect savings separately to the CFO. Create a scorecard that separates indirect savings from direct-material savings. Finance needs to validate and attribute the numbers. Without this, indirect savings remain invisible and unrewarded. Expected outcome: finance-validated indirect savings line in quarterly procurement report within 3 months.

What is the difference between direct and indirect procurement?

Direct procurement covers materials that become part of the finished product — raw materials, components, packaging. Indirect procurement covers everything else: MRO supplies, IT hardware, professional services, facilities management, and travel. Indirect goods do not enter the final product but are essential for operations.

Why does indirect procurement get less analytical attention than direct?

Indirect spend is decentralized, fragmented across departments, and historically viewed as non-strategic. MRO alone generates 70-80% of all procurement transactions but accounts for only 5-10% of COGS. Procurement teams allocate resources by dollar value, not transaction complexity, creating a blind spot for high-volume, low-visibility categories.

How much of revenue goes to indirect procurement?

Indirect spend typically equals 15-27% of company revenue. For service businesses, indirect can reach up to 90% of total procurement spend. Manufacturing sectors spend 0.5-4.5% of annual revenue on MRO alone.

What is the biggest source of leakage in indirect procurement?

Maverick spend — purchases made outside approved contracts and suppliers — is the single largest source of value leakage. When procurement has low visibility into decentralized indirect buying, departments revert to ad-hoc purchasing at unnegotiated rates, inflating costs by 10-30% compared to contracted pricing.
