Compliance gaps usually emerge when policies are written for centralized procurement teams but execution happens across departments with different urgency, incentives, and tools.
Local teams may not understand approval thresholds, supplier restrictions, or documentation requirements. Even if each transaction looks harmless, cumulative control drift creates meaningful audit and financial exposure.
A common pattern is split transactions used to stay below approval limits. Another is inconsistent use of preferred suppliers for recurring low-value spend. These patterns are difficult to detect without consolidated data views.
The solution is not to remove decentralization. It is to define non-negotiable controls, automate exception visibility, and assign clear accountability for corrective action.
