Detect Maverick Spend
An employee needs something quickly, doesn't know or doesn't bother checking whether there's already a negotiated vendor contract for that category, and just orders it directly, on a personal card or a quick one-off PO, at whatever price the first vendor they find offers. Individually these purchases look trivial, but in aggregate maverick spend, purchases made outside preferred vendor agreements and negotiated pricing, quietly erodes both the leverage procurement negotiated and the volume discounts that depend on spend actually flowing through the contracted channel, and it usually stays invisible because nobody's systematically comparing what got bought against what should have gone through an existing agreement.

How the automation works
We compare purchase activity against the catalog of categories with an existing preferred vendor agreement, flagging purchases in a covered category that went to a non-preferred vendor or bypassed the standard requisition channel entirely. Each flagged purchase gets checked for a legitimate exception, an emergency purchase, a genuine gap in the preferred vendor's capability, versus a purchase that simply should have gone through the existing contract, and the pattern is aggregated by department and requester so procurement can see where maverick spend concentrates rather than chasing one purchase at a time. The goal isn't punishing every off-contract purchase, it's making the volume of leaking spend visible enough that procurement can actually address the root cause, whether that's easier catalog access or better awareness of existing agreements.
Process flow
- 01
Load preferred vendor catalog trigger
Categories with an existing preferred vendor agreement and negotiated pricing are loaded as the comparison baseline.
- 02
Monitor purchase activity integration
Purchases across AP, card transactions, and requisitions are monitored for category and vendor against the preferred catalog.
- 03
Flag off-catalog purchases ai
Purchases in a covered category that went to a non-preferred vendor, or bypassed the standard requisition process, are flagged.
- 04
Check for legitimate exception ai
Flagged purchases are checked against known legitimate exception patterns, an emergency need, a capability gap, versus routine avoidable maverick spend.
- 05
Aggregate by department and requester output
Maverick spend patterns are aggregated by department and requester, surfacing where off-contract spend concentrates rather than treating each purchase in isolation.

- Known legitimate exception criteria

Outputs

Where this goes wrong if you get it wrong
- Not every off-catalog purchase is a real problem, a genuine emergency need or a preferred vendor's real capability gap justifies going outside the normal channel, flagging every deviation the same way as clear avoidable maverick spend will generate resistance from employees who had a legitimate reason and feel unfairly scrutinized.
- Maverick spend detection framed as catching individual wrongdoing tends to make people defensive and less transparent about future purchases, framing this as closing gaps in catalog access and awareness, not policing individual employees, gets better long-term compliance than a punitive approach.
- A preferred vendor catalog that's genuinely hard to find or use, buried in a clunky system, will keep generating maverick spend regardless of how well detection works, the aggregated pattern data should feed back into fixing the actual friction driving people around the preferred channel, not just flagging the symptom repeatedly.
- Aggregating maverick spend by department without accounting for genuinely different purchasing needs across departments can make one team look like a worse offender than it is, a department buying more unique, non-catalog items by the nature of its work isn't necessarily behaving worse than one with more standardized needs.
Frequently asked questions
Does a flagged purchase get blocked or reversed?
No, this is a detection and reporting tool, not a blocking mechanism, flagged purchases have already happened, the value is in the aggregated pattern informing future procurement policy and catalog improvements.
How does it distinguish a legitimate emergency purchase from avoidable maverick spend?
Against defined exception criteria, an urgent need with documented justification, a real capability gap with the preferred vendor, purchases meeting those criteria are tracked separately from routine avoidable off-contract spend.
Is this used to discipline individual employees who buy off-contract?
It's most effective used at the aggregate department and pattern level to fix systemic issues like catalog accessibility, using it to target individual employees tends to reduce transparency and push maverick spend further underground.
Does this cover card transactions as well as formal purchase orders?
Yes, it monitors across purchase channels, including card transactions, since a meaningful share of maverick spend happens on cards rather than through a formal requisition.
