Spend Under Management (SUM) is the portion of an organization's contingent-workforce spend that is actively tracked and managed through a formal program, typically via a Vendor Management System (VMS) and/or a Managed Service Provider (MSP), with defined suppliers, standardized rate cards, and enforced controls. It is one of the most important performance metrics for any contingent-workforce program: the higher the percentage of spend under management, the greater an organization's visibility, compliance, and negotiated savings. Spend that falls outside the program, often called 'maverick' or rogue spend, is uncontrolled and carries higher costs and greater compliance risk. In practice, Spend Under Management is expressed as a percentage of total contingent-workforce spend, and leading programs work continuously to move more of that spend inside the managed framework.
Spend Under Management turns fragmented, ad-hoc contingent spending into a governed program. Instead of individual hiring managers engaging staffing agencies on their own terms, all requisitions, suppliers, rates, and invoices flow through a central system with agreed rules. That system is usually a Managed Service Provider (MSP), a Vendor Management System, or a Freelance Management System, and it becomes the single source of truth for every dollar of contingent-workforce spend.
Once spend is inside the program, the organization gains leverage and oversight it cannot get from scattered relationships:
The goal is not just measurement. Each point of spend moved under management typically unlocks negotiated savings, tighter compliance, and cleaner reporting.
Spend Under Management is expressed as a simple ratio, usually reported as a percentage:
Spend Under Management % = (Managed contingent spend / Total contingent spend) x 100
The numerator is every dollar flowing through the formal program, with defined suppliers, rate cards, and controls. The denominator is all contingent-workforce spend across the enterprise, including anything procured outside the program. The gap between the two is your maverick spend, and closing it is the core objective of most program-maturity roadmaps.
A higher percentage is almost always better, because uncontrolled spend is where budget overruns and worker misclassification risk concentrate. For a deeper look at closing that gap, see why contingent budgets go over and how to stop it.

Book a Demo Spend Under Management is often confused with total spend or with the tools used to manage it. The distinction matters because each concept answers a different question.
| Concept | What it measures | Key question it answers |
|---|---|---|
| Spend Under Management | Share of spend inside a formal program | How much of our spend is actually controlled? |
| Contingent-workforce spend | Total dollars spent on contingent labor | How much are we spending overall? |
| Maverick / rogue spend | Spend outside the program | What are we failing to control? |
| Total cost of workforce | All-in cost of every worker type | What does our full workforce truly cost? |
Put simply, contingent-workforce spend is the total, Spend Under Management is the governed slice of that total, and total cost of workforce is the broader all-in figure. Tools like an MSP or FMS are how you raise the percentage, not the metric itself.
WorkGenius brings more of your contingent spend under management by consolidating sourcing, classification, onboarding, management, and payment onto one platform, so engagements that once happened outside your program come inside it. That means fewer scattered vendor relationships and less maverick spend leaking your budget.
The result is a higher percentage of spend under management with the visibility and savings that come with it. Explore the Contingent Workforce Management playbook or read how to get real-time visibility into contingent spend across your company.
There is no single universal benchmark, but the principle is clear: higher is better. Mature contingent-workforce programs bring the large majority of their spend inside a formal program, leaving only rare exceptions outside. The remaining maverick spend is where budget overruns and compliance risk concentrate, so the practical goal is to steadily move more spend under management over time rather than hit one fixed number.
Contingent-workforce spend is the total amount your organization spends on non-employee talent. Spend Under Management is the governed slice of that total that flows through a formal program with defined suppliers, rate cards, and controls. Total spend tells you how much you spend; Spend Under Management tells you how much of it you actually control.
Maverick spend is contingent spending that happens outside the managed program, often when a hiring manager engages a vendor directly. Because it sits outside standardized rate cards and compliance checks, it typically costs more and carries higher misclassification and co-employment risk. Reducing maverick spend is the fastest way to raise your Spend Under Management percentage.
Organizations raise their Spend Under Management percentage using a Managed Service Provider, a Vendor Management System, or a Freelance Management System. These systems centralize suppliers, enforce rate cards, and capture every requisition and invoice. WorkGenius consolidates sourcing, compliance, management, and payment into one platform to bring more spend inside a single governed program.
Once spend is inside the program, the organization can negotiate standardized rate cards, cap markups, consolidate suppliers, and use direct sourcing to reduce agency fees. It also produces clean data for forecasting and audits. More visibility plus more leverage equals lower cost, which is why Spend Under Management is a core financial metric for contingent programs.
