1. A method for checking and creating a finalized invoice before billing a client, the method comprising: submitting a preliminary invoice to an automated rules engine running on a computer processor before a final invoice is sent to a client, the preliminary invoice including one or more entries associated with one of a task or an expense; automatically searching the preliminary invoice for one of an expense associated with a task listed in the preliminary invoice or a task associated with an expense listed in the preliminary invoice in a computer-implemented process; automatically querying a user to add one of the associated expense for the task or the associated task for the expense when the search of the preliminary invoice fails to locate the associated expense or associated task listed in the invoice in a computer-implemented process; automatically modifying the preliminary invoice based on a user input received in response to the query in a computer-implemented process, the preliminary invoice including a modified entry that includes the associated expense or the associated task; automatically searching the preliminary invoice for at least one of keywords, phrases, and task billing codes that define possible violation of a company's billing guidelines in a computer-implemented process; and automatically suggesting to the user alternative at least one of keywords, phrases, and task billing codes to be substituted for those that define possible violation of the company's billing guidelines in a computer-implemented process; automatically modifying the preliminary invoice based on a user input received in response to the suggestion in a computer-implemented process, the preliminary invoice including a modified entry that includes the suggested alternative at least one of keywords, phrases, and task billing codes; automatically searching the preliminary invoice for a related fee activity associated with each specific expense billed in the preliminary invoice in a computer-implemented process, wherein when the automated search of the preliminary invoice fails to find a related fee activity associated with a specific expense billed, the method further comprising automatically prompting the user to add the related fee activity not found in a computer-implemented process; automatically modifying the preliminary invoice when a related fee activity not found in the preceding step is added by the user in a computer-implemented process, the preliminary invoice including a modified entry that includes the related fee activity added by the user; and automatically generating a final invoice in a computer-implemented process based on the modified entries for sending to a client for payment.
