Procurement teams invest months negotiating favorable contracts, securing volume discounts, and vetting strategic suppliers. Yet, those hard-won savings often evaporate before they ever hit the bottom line. This is exactly where procurement margin quietly leaks away.
The culprit is usually maverick spend.
When employees, site managers, or localized teams bypass established procurement channels to make independent purchases, it creates a ripple effect of margin erosion and operational inefficiency. To reclaim that lost value, organizations must first understand why rogue purchasing happens and how to systematically identify it within their data.
What Is Maverick Spend?
Maverick spend—sometimes referred to as rogue spend or off-contract buying—occurs when goods or services are purchased from suppliers outside of the organization’s pre-negotiated contracts and approved procurement workflows.
Common examples include:
- An IT manager purchasing software licenses directly with a credit card instead of using the enterprise agreement.
- A site engineer buying localized safety equipment from a nearby hardware store to avoid a lengthy purchase order (PO) approval process.
- Department heads sticking with legacy suppliers out of habit, even after procurement has mandated a transition to a new strategic vendor.
While these individual transactions might solve an immediate operational need, they actively undermine the broader financial health of the organization.
Why Maverick Spend Matters
Maverick spend is often one of the largest sources of procurement value leakage because it directly bypasses negotiated contracts and procurement controls.
Organizations frequently discover that a meaningful percentage of purchasing activity occurs outside approved contracts, supplier agreements, or purchasing workflows. Even relatively small levels of off-contract buying can significantly reduce the savings achieved through strategic sourcing initiatives.
How to Measure Maverick Spend
A simple formula is:
Maverick Spend % = (Off-Contract Spend ÷ Total Addressable Spend) × 100
For example:
- Total Addressable Spend: AED 10M
- Off-Contract Spend: AED 1.2M
- Maverick Spend Rate = 12%
Tracking this KPI quarterly helps procurement leaders understand whether compliance is improving or deteriorating.
Common Warning Signs of Maverick Spend
Organizations experiencing high levels of maverick spend often notice:
- Rapid growth in supplier count
- Frequent non-PO invoices
- High P-card usage
- Multiple suppliers providing identical goods
- Low contract utilization rates
- Large volumes of emergency purchases
- Significant price variation for similar items
These indicators often appear months before procurement teams realize the scale of the problem.
The True Cost of Rogue Purchasing
Maverick spend is not just an administrative annoyance; it has direct, measurable impacts on the balance sheet.
1. Lost Savings and Price Premiums
When buyers go off-contract, they lose access to negotiated catalog pricing. Even a 5% to 15% premium on routine purchases can add up to hundreds of thousands of AED in annual procurement spend leakage. Furthermore, spreading purchases across unapproved vendors prevents the organization from hitting volume tiers that trigger valuable supplier rebates.
2. Vendor Master Bloat
Every time a new, unvetted supplier is used, they are often added to the ERP system to process payment. This causes the vendor master data to balloon with low-value, single-use suppliers, drastically increasing the administrative burden on the Accounts Payable team.
3. Increased Risk and Compliance Gaps
Approved suppliers undergo rigorous vetting for financial stability, cybersecurity standards, and regulatory compliance. Maverick purchases bypass these controls entirely, exposing the business to unnecessary legal, operational, and reputational risks.
Why Does Maverick Spend Happen?
To fix maverick spend, you must understand the behavioral drivers behind it. Employees rarely go off-contract maliciously; they usually do it out of perceived necessity.
The most common drivers include:
- Process Friction: The official procurement process takes too long, requiring multiple layers of approval for low-risk items.
- Poor Visibility: Employees simply do not know a contracted supplier exists for the item they need.
- Urgency: Operational emergencies (e.g., a broken machine on a manufacturing floor) force buyers to prioritize speed over policy.
- Decentralized Authority: A lack of centralized oversight allows localized budgets to operate in silos without accountability.
How to Bring Maverick Spend Under Control
Stopping rogue purchasing requires a mix of data visibility, process improvement, and organizational change management.
Step 1: Quantify the Problem with Spend Analytics
You cannot control what you cannot see. The first step is to analyze your Accounts Payable data, expense reports, and P-card transactions. By mapping this raw data against your known supplier contracts, you can identify exactly which departments are bypassing procurement and exactly how much it is costing the company.
Step 2: Simplify the Purchasing Path
If going rogue is easier than following the rules, employees will go rogue. Implementing user-friendly, consumer-style e-procurement catalogs ensures that finding and buying from contracted suppliers is the path of least resistance.
Step 3: Streamline the PO Process for Tail Spend
Not every purchase requires a strategic sourcing event. For low-value, routine purchases (tail spend), implement streamlined approval workflows. If employees know a PO for basic supplies will be approved in hours rather than weeks, they are far less likely to bypass the system.
Step 4: Communicate Contracts Effectively
Procurement cannot negotiate a great contract and simply file it away. The details of these agreements—and the benefits of using them—must be actively communicated to the stakeholders and business units who actually make the day-to-day purchasing decisions.
Shifting from Reactive to Proactive
Auditing for maverick spend once a year is no longer sufficient. Across the industry, modern procurement teams are increasingly leveraging spend analytics to flag off-contract purchases as they enter the system — a capability that lets them correct buying behavior closer to real time rather than discovering the margin loss months later.
By turning a light on the hidden corners of your purchasing data, you can transform maverick spend from a persistent leak into a concrete savings opportunity.

Frequently asked questions
What exactly is considered maverick spend?
Maverick spend, also known as rogue spend, refers to purchases made outside of agreed-upon contracts, approved vendor lists, or standard procurement processes.
Why is maverick spend dangerous for organizations?
It bypasses negotiated discounts, weakens supplier leverage, introduces unvetted compliance risks, and clutters the vendor master database with duplicate or low-value suppliers.
How can we measure maverick spend if it happens off-system?
Maverick spend usually still leaves a financial footprint, often via P-cards, expense reports, or non-PO invoices. By categorizing accounts payable (AP) data and cross-referencing it with active contracts, you can uncover these off-contract purchases.
Will punishing employees stop maverick spend?
Rarely. Most maverick spend happens because standard procurement processes are too slow, complex, or invisible to the end-user. Making the correct purchasing path the easiest path is far more effective than enforcing strict penalties.
