- Maverick spend has four categories of root causes and can be measured effectively with modern-day spend and contract analytics.
- Top performers can reach +90% contract compliance using a combination of AI-powered spend analytics, guided buying tools, and automated compliance monitoring.
- Speed matters. Organizations using Suplari's AI data platform can establish baseline maverick spend metrics and implement solutions within weeks—without waiting for perfect data
What is maverick spend, exactly?
Maverick spend occurs when employees purchase goods or services outside established procurement processes, approved suppliers, or negotiated contract terms. Maverick spending can occur even with suppliers that have been approved in the past.
Critical distinction: Maverick spend differs from tail spend. Tail spend refers to low-value purchases across many suppliers. It may be unmanaged but isn't necessarily non-compliant. Maverick spend specifically involves circumventing established processes.
According to The Hackett Group's research, organizations lose between 5-16% of targeted savings to maverick buying.
The most common types of maverick spending include:
- Unapproved suppliers (74% cite as primary concern) – Buying from vendors not vetted by procurement
- Wrong channels (68%) – Using approved suppliers but bypassing e-procurement systems
- Unapproved categories (43%) – Buying outside authorized spend areas
- Off-contract pricing (34%) – Paying rates different from negotiated contracts
Root causes of maverick spend
Maverick spend can occur for different reasons across different organizations. Generally you can group key reasons into four categories: technology gaps, cultural issues, information failures and process design flaws.
Understanding why employees bypass procurement processes is essential for designing effective solutions. These root causes fall into four categories.
How to measure maverick spend
You can't control what you can't measure. Before implementing solutions, procurement teams need to establish a baseline understanding of their maverick spend problem—how much is occurring, where it's happening, and what it's costing the organization.
Calculate your maverick spend rate
The maverick spend rate is the foundational metric for understanding non-compliant purchasing. It measures the percentage of total organizational spending that occurs outside established procurement processes and approved contracts.
Maverick Spend Rate = (Total Spend Outside Approved Channels / Total Company Spend) × 100
For example, if your organization spends $50 million annually and $7.5 million bypasses procurement processes, your maverick spend rate is 15%.
According to The Hackett Group research, organizations lose between 5-16% of targeted savings to maverick buying. For a company with $500M in annual spend, that translates to $25-80M in lost value every year.
Understand the three levels of maverick spend
Not all maverick spend is created equal. Modern spend analysis distinguishes between three types based on visibility and control:
Level 1: Fully unknown and uncontrolled
You receive an invoice from an unknown vendor for goods or services you weren't aware of. Neither the expense nor the supplier appears in established procurement records. This represents the highest risk category—completely outside your procurement ecosystem.
Level 2: Partially known and partly controlled
The purchase involves a vendor you know and have worked with before, but you don't know what was purchased. The approved supplier was used, but the established procurement process wasn't fully followed. This often happens when employees contact suppliers directly rather than going through proper channels.
Level 3: Known and partly controlled
You know the vendor and the nature of the purchase, but details like pricing or quantities deviate from contract terms. The buyer may have used an approved supplier but negotiated different terms or exceeded authorized volumes without proper approval.
Each level requires different detection methods and remediation strategies. Complete visibility starts with identifying which types of maverick spend exist in your organization.
Quantify the financial impact
Measuring maverick spend isn't just about compliance rates. You need to quantify the actual financial impact to build the business case for change.
Lost savings from negotiated contracts
Calculate the difference between contracted rates and what you actually paid for off-contract purchases. Organizations report up to 16% loss in negotiated savings due to maverick spend.
Volume discount opportunities missed
When spending fragments across multiple suppliers instead of consolidating with preferred vendors, you lose volume leverage. Measure potential discounts you could capture by consolidating maverick spend with contracted suppliers.
Processing cost premium
Maverick purchases create administrative burden—invoice reconciliation, supplier onboarding, payment processing—that exceeds the value of what you're buying. Calculate the fully-loaded cost to process each maverick transaction versus purchases through established channels.
Risk exposure and compliance costs
Unapproved suppliers may not meet quality standards, ESG requirements, or regulatory compliance obligations. While harder to quantify, these risks create potential financial exposure through contract breaches, quality failures, or regulatory penalties.
Establish your baseline before implementing solutions
Don't wait for perfect data to start measuring. Even basic visibility into maverick spend drives better decision-making than operating blind.
Start by analyzing 6-12 months of historical spend data. Modern AI platforms can deliver insights from imperfect data in weeks—you don't need a perfect enterprise data infrastructure to begin.
Focus initially on high-value categories where maverick spend creates the greatest financial impact. As one Suplari customer discovered, analyzing just their marketing contracts (not complete spend data) revealed inefficiencies that shaped their entire category optimization strategy for the following year.
Track your maverick spend rate monthly or quarterly. The goal isn't to reach zero—some flexibility will always be necessary for legitimate business needs. Top-performing organizations achieve 90%+ contract compliance through the right combination of visibility, processes, and tools.
The measurement foundation you establish through spend analytics becomes the basis for everything that follows. Without it, you're implementing solutions without knowing whether they work.
With a clear understanding of your maverick spend baseline and financial impact, you're ready to implement targeted strategies that address root causes and drive measurable compliance improvements.
Strategy 1: Implement Spend Visibility
The foundation of all other strategies. You can't control maverick spend without seeing it.
✓ Deploy unified spend visibility tools that aggregate spend data from all sources: purchase orders, invoices, corporate cards, expense reports, and direct billing
✓ Use AI-powered spend classification to automatically categorize transactions and flag non-compliant spending
✓ Create real-time dashboards that show procurement, finance, and business unit leaders exactly where rogue spending is happening
Real Impact: Organizations implementing enterprise spend visibility typically see a 20-30% reduction in maverick spend within 90 days, simply by making the problem visible. Visibility creates accountability.
The Visibility Payoff: Suplari customers often discover that once business unit leaders see their own maverick spend metrics on a dashboard, compliance improves without heavy-handed enforcement. Transparency drives behavior change.
Strategy 2: Create a Curated Catalog of Approved Suppliers and Contracts
Make compliant buying easier than non-compliant buying.
✓ Publish an easily accessible, mobile-friendly catalog of approved suppliers with contract terms, pricing, and terms of service
✓ Include relevant contract terms in the catalog—payment terms, volume discounts, service levels—so employees know what they're getting
✓ Update the catalog in real time as new suppliers are approved or contracts change
✓ Use price intelligence to monitor pricing variance and flag when market prices shift significantly from contract rates
Real Impact: When employees can find an approved supplier in 30 seconds and know the pricing is competitive, they use it. Friction is the biggest driver of maverick spending.
Strategy 3: Strengthen Contract Visibility and Terms Communication
Employees can't follow contracts they don't know about.
✓ Implement contract intelligence platforms that surface key terms—pricing, volume discounts, renewal dates, payment terms—at the point of purchase
✓ Use guided buying workflows that remind employees of approved suppliers and contract terms before they order
✓ Set automated alerts when transactions approach contract limits or when renegotiation windows open
✓ Use contract negotiation intelligence to ensure all contracts are structured for easy compliance
Real Impact: When a guided buying tool surfaces a contract term showing that your company negotiated net-60 payment terms with a vendor, employees use those terms. They're not being non-compliant; they just didn't have the information.
Strategy 4: Simplify the Purchasing Process
Complexity drives maverick spending. Make the compliant path the easiest path.
✓ Streamline approval workflows—remove unnecessary sign-offs and bottlenecks
✓ Use AI agents to automate routine purchase requests and accelerate approval
✓ Create fast-track approval processes for urgent or low-risk purchases
✓ Build integration between your e-procurement system and the tools employees already use daily (email, Slack, Teams)
✓ Empower employees to make low-dollar purchases without approval while maintaining controls for higher-value spend
Real Impact: When an employee can request an office supply reorder and get it in 3 clicks, they do. When it takes 10 approvals and 2 weeks, they use their corporate card on Amazon instead.
Top Performers: Leading organizations set clear purchasing rules: purchases under $500 are auto-approved if within budget and from an approved supplier. This removes friction without sacrificing control.
Strategy 5: Use Guided Buying and Compliance Alerts
Real-time nudges prevent maverick spending before it happens.
✓ Implement strategic sourcing workflows that guide employees to preferred suppliers and contracts
✓ Use real-time alerts to flag when a purchase is about to occur off-contract or from an unapproved vendor
✓ Show employees the cost difference: "This item is $50 cheaper from your approved vendor"
✓ Provide one-click options to switch to approved suppliers before checkout
✓ Maintain exception handling—if an employee needs to buy off-contract, they can request an exception with business justification, which gets routed to procurement
Real Impact: Guided buying reduces maverick spend by 15-25% in the first 90 days. It works because it meets employees where they are and makes compliance frictionless.
Strategy 6: Establish Ongoing Monitoring and Feedback Loops
Maverick spend isn't a one-time fix; it's an ongoing discipline.
✓ Establish monthly (or weekly) compliance metrics and review them with business unit leaders
✓ Use savings tracking to show the direct financial impact of compliance
✓ Identify patterns in maverick spending—certain departments, certain categories, certain suppliers—and address root causes specifically
✓ Provide feedback to offenders: "Your department's maverick spend rate is 12%; here's how to improve it"
✓ Celebrate wins: "Marketing switched 40% of their creative spend to approved vendors and saved $300K"
✓ Implement compliance monitoring and governance workflows that escalate high-risk exceptions
Real Impact: Organizations that treat maverick spend control as an ongoing discipline (not a one-time project) sustain 90%+ compliance rates. Those that don't monitor continuously drift back to 20-25% maverick spend within 6 months.
What AI-powered spend analytics reveals
Traditional spend analysis methods—spreadsheets and manual data reviews—struggle to detect maverick spending at scale. Modern AI-powered spend analytics platforms like Suplari automatically identify non-compliant purchasing patterns across your entire spend landscape.
These platforms reveal:
Off-contract purchasing patterns by department, category, and supplier
AI identifies which business units drive the most maverick spend and which categories show the highest non-compliance rates. This targeting enables focused intervention rather than organization-wide policy enforcement.
Price variance between contracted and actual rates
Automated contract-to-invoice matching flags when you pay more than negotiated rates, even with approved suppliers. One Suplari customer discovered systematic pricing leakage where actual payments exceeded contracted rates by 12%—recoverable money that remained invisible without automated detection.
Duplicate supplier records masking true spend concentration
Suppliers often appear in your systems under multiple names and variations. AI consolidates these duplicates to reveal actual spending with each supplier, exposing hidden maverick spend where employees use different supplier records to bypass controls.
Tail spend patterns indicating process workarounds
High volumes of small purchases from unapproved suppliers suggest employees are bypassing procurement for routine items. AI identifies these patterns even when individual transactions seem insignificant.
Payment term discrepancies leaving money on the table
Automated analysis catches when negotiated payment terms aren't applied consistently. One Fortune 2000 CFO using Suplari discovered payment terms that should have converted to Net 60 eighteen months earlier were still processed as immediate payment, with over $150,000 in working capital unnecessarily tied up.
The bottom line on wrangling maverick spend
Maverick spending isn't just a procurement annoyance. It's a multi-million dollar problem that undermines strategic initiatives, damages supplier relationships, and creates unnecessary risk exposure. But it's also solvable.
The six strategies outlined above work together as a system:
Organizations that implement all six—using modern spend analytics, contract intelligence, supplier intelligence, AI agents, and savings tracking—routinely reach 90%+ contract compliance and recover millions in annual savings.
Suplari's complete suite—including our AI data platform, spend visibility, spend classification, price intelligence, and compliance monitoring and governance capabilities—enables all of this in weeks, not months, working from imperfect data out of the box.
The organizations winning at maverick spend control aren't waiting for perfection. They're moving fast, learning continuously, and letting their data compound in value.
