Abstract: The present invention relates to systems and methods for automated audit analysis and providing of cost reduction recommendations associated with services used and/or received by an entity. In general, invoice data associated with a service associated with an entity (e.g. a customer) is obtained and processed in order to identify at least one of billing errors and inefficiencies. The processing of invoice data is generally performed by computationally identifying relevant invoice information and comparing this information with data from a proprietary service optimization database. When errors and/or inefficiencies are identified, recommendations to remedy the inefficiencies and/or errors are provided to the entity so that cost reduction actions can be taken.
