The accounting profession uses various tools to generate accurate accounting information at the close of accounting cycles (monthly, quarterly and annually). The primary document is the working trial balance. It is very similar to the traditional trial balance except there are additional columns used to identify various adjustments and the corresponding source documents (work papers).
Professional accounting services use various schedules, reports from the accounting software, charts, ledgers and spreadsheets to support their position taken in regards to each of the respective account balances with a trial balance. These supporting documents are called ‘Work Papers’.
