Abstract: A system for evaluating an invoice for work includes a processing device configured for determining one or more billing data parameters comprising a threshold payment amount based on information associated with the invoice or the work, retrieving from a historical billing database, historical billing data corresponding to the one or more determined billing data parameters, comparing the retrieved historical billing data including the threshold payment amount with at least a portion of the information extracted from the invoice including billing information extracted from the invoice, and determining whether to approve the invoice based on the comparison, wherein determining whether to approve the invoice is dependent upon the comparison of the threshold payment amount with the requested payment amount corresponding to billing information extracted from the invoice.
