A local parts vendors improperly billed the Town of Chapel Hill at least $210,035 for parts that did not match the associated work orders over a 15-month period. The Town and parts vendor reviewed the errors identified by investigators and agreed that at least $134,000 of those parts were not placed on Town vehicles. The Town did not detect these errors due to a lack of systems interface, inadequate parts detail reporting by the vendor, and insufficient review of monthly invoices by the Town's Fleet Manager.
