This is P-06 in our complete procurement guide. Indirect spend is a primary focus of category management in the ISM framework — and it is consistently where the largest near-term savings opportunities sit for mid-market organizations.
Why Indirect Is Harder Than Direct
Direct procurement is easier to manage because it's centralized. Indirect is decentralized by nature — every department is a procurement function of its own. The result: the same category purchased from 8 different vendors across 6 business units, each paying different rates, with no leverage from the collective spend.
The Four Indirect Spend Problems
Each problem requires a different intervention. Solving one without addressing the others produces partial results. A complete indirect spend programme addresses all four simultaneously.
1. Spend Visibility
Indirect spend is scattered across ERP purchase orders, P-cards, expense reports, and corporate credit cards. The first work is consolidating all this data into a single spend view. Our
20–30% of indirect spend bypasses procurement controls. Root cause: the approved procurement process is too slow or bureaucratic relative to the urgency of the need. Fix: deploy
The long tail of small purchases requires a different approach than strategic categories: preferred vendor programmes, catalogue purchasing, P-card with controls. Our
The average mid-size company has 250+ software applications, and 30–40% are significantly underutilized. Our IT vendor management guide covers the governance model for managing SaaS spending specifically — inventory, utilization tracking, renewal management, and procurement routing policy for new SaaS purchases.2.

Where is spend most fragmented? The ISM category management framework identifies IT, facilities, marketing services, and professional services as the highest-opportunity categories in most organizations. Rank by fragmentation and volume — consolidation value is highest where both are high.Identify the Top 10–15 Indirect Categories

Competitive RFP using our vendor consolidation play depending on the category. Not every indirect category warrants a full RFP — calibrate the intervention to the savings opportunity and market maturity.
Implement Catalogue and Guided Buying
For common high-frequency purchases, catalogue and guided buying removes the friction that drives maverick spend. When the compliant path is faster than the workaround — because the preferred vendor and price are pre-negotiated and visible — compliance follows naturally.
A simple preferred vendor list with pre-negotiated rates for the long tail eliminates the effort of individual purchasing decisions below a threshold. P-card with controls — category restrictions, vendor restrictions, transaction limits — handles the remainder without creating AP invoice processing burden.Address Tail Spend with Preferred Vendor List and Pre-Negotiated Rates

Frequently Asked Questions
Indirect spend covers everything that doesn't go into your product — IT subscriptions, marketing agencies, facilities, professional services, travel. The average US mid-market company has indirect spend equal to 15–25% of revenue. It differs from direct spend in that it is decentralized, fragmented, and typically managed by many departments rather than a central procurement team.
Direct procurement is easier to manage because it's centralized. Indirect is decentralized by nature — every department is a procurement function of its own. The result: the same category purchased from 8 different vendors across 6 business units, each paying different rates, with no leverage from the collective spend.
The four core problems are: (1) Spend visibility — indirect spend is scattered across ERP POs, P-cards, expense reports, and corporate credit cards; (2) Maverick spend — 20–30% bypasses procurement controls; (3) Tail spend — the long tail requires a different approach than strategic categories; (4) SaaS sprawl — the average mid-size company has 250+ software applications with 30–40% significantly underutilized.
Realistic savings: 6–15% on addressable indirect spend. On $30M of indirect spend, a well-executed programme should produce $2–4M in annual savings plus significant administrative cost reduction from reduced vendor management overhead.
The ISM category management framework identifies IT, facilities, marketing services, and professional services as the highest-opportunity categories in most organizations. These categories share three characteristics: high spend, high fragmentation across multiple vendors, and consistent undermanagement by procurement. SaaS specifically is worth addressing first — underutilization savings are immediate without changing vendors or running RFPs.
