Maverick spend, the practice of purchasing goods and services outside of established procurement channels, is a persistent and costly challenge for organizations. It erodes negotiated savings, introduces supplier risk, and creates a significant lack of visibility into enterprise-wide expenditure. While many companies struggle to get a handle on it through manual audits and policy reminders, a more systematic and powerful solution lies in the application of artificial intelligence. By adopting a structured approach, procurement teams can transform raw data into actionable intelligence to finally rein in this unmanaged spending.
The Challenge of Unstructured Data
The primary obstacle in identifying maverick spend is that it hides in plain sight within vast, unstructured datasets. It lives in P-card statements, expense reports, and non-PO invoices, often described with vague line-item details like “miscellaneous supplies” or “project services.” Traditional, rules-based systems fail to catch these transactions because they lack the nuance to understand context. Manually reviewing this data is an impossibly time-consuming task, meaning most maverick spend goes undetected until long after the purchase, if at all. This is where a methodical AI implementation becomes essential.
A Structured Approach: The 7-Step Framework
To effectively tackle this problem, organizations can apply a seven-step AI framework. The first step is Problem Definition, which involves clearly articulating the goal: to identify and reduce maverick spend by a specific percentage. Next is Data Aggregation and Preparation, where data from all relevant sources—invoices, expense reports, and card statements—is collected, cleaned, and standardized into a usable format.
The third step is Model Selection. For maverick spend, a combination of Natural Language Processing (NLP) and anomaly detection models is highly effective. NLP can interpret the free-text descriptions of purchases, while anomaly detection can flag transactions that deviate from normal purchasing patterns. The fourth step, Model Training, involves feeding historical data to the AI. The system learns to distinguish between compliant purchases made from preferred suppliers and non-compliant ones.
Following training is Evaluation, where the model's accuracy is tested against a validation dataset to ensure it correctly identifies maverick transactions without generating excessive false positives. Once validated, the sixth step is Deployment. The AI model is integrated into the procurement workflow, perhaps as a tool that analyzes expense reports in real-time or provides a daily dashboard of non-compliant activity. The final step is Monitoring and Iteration. The AI's performance is continuously tracked, and the model is retrained with new data to adapt to changing spending patterns and improve its accuracy over time.
From Insight to Strategic Action
The true power of this process extends beyond simply flagging individual transactions. The AI can identify patterns and trends that are invisible to the human eye. For example, it might reveal that a specific department consistently purchases office supplies from a non-preferred online retailer at a 20% premium. This is where the true value of the AI Framework in Procurement is realized. Armed with this data-driven insight, procurement leaders can take strategic action. They can approach the department to understand their needs, add the required items to a preferred supplier catalog, or negotiate a new contract with a more suitable vendor, turning a reactive problem into a proactive, value-adding strategy. By methodically applying AI, organizations can move from a state of chaotic, unmanaged spending to one of control, visibility, and strategic financial stewardship.
