The general ledger is the core of your company’s financial records.  These records constitute the central “books” of your system.  Since every transaction flows through the general ledger, a problem with your general ledger throws off all of your books.  Having us review your general ledger system each month allows us to hunt down any discrepancies such as double billings or any unrecorded payments.  We will then fix the discrepancies so that your books are always accurate.
